NCLEX Flashcards
1
Q
Diseases with too much aldosterone
A
Cushings (too much of all steroids), hyperaldosteronism (Conn’s)
2
Q
too little aldosterone
A
Addisons- Need to ADD steroids- will go into FVD
3
Q
ANP action
A
in response to atrial stretch (from vol excess) released to cause excretion of sodium and water
4
Q
goes up with concentration and down in dilution
A
urine specific gravity, sodium and hematocrit
5
Q
Anti diuretic hormone action (ADH)
A
causes retention of only water- think ADH-H20. ADH from pituitary in head- head injury or sx? increased ICP?
6
Q
too much ADH
A
SIADH- too many letters, too much water! Na does not follow the water. retain water- FVE. urine concentrated (being retained) and blood dilute
7
Q
too little ADH
A
DI= Diurese. Lose water, FVD, urine dilute and blood concentrated.
8
Q
normal CVP
A
2-6 mmHg, or 5-10 cmH20
9
Q
Fluid retention think
A
heart problems first. Watch the weight on all heart patients.
10
Q
assessment or evaluation think
A
signs and symptoms
11
Q
Bed rest induces
A
diureses- blood comes back to core- atrial stretch- ANP and reduction of ADH. Everything thinker- pulmonary secretions (pneumonia), blood (DVT), kidney stones- push fluids unless contraindicated. watch for crackles, edema, weight, BP, CVP
12
Q
IVF slowly to
A
old, young, hx of heart or kidney problems
13
Q
polyuria think
A
shock. loss of fluids from anywhere: thoracentesis, paracentesis, vomiting, diarrhea, hemorrhage, third spacing.
14
Q
sxs FVD
A
decreased weight, BP, UO, skin turgor, dry membranes, increased respiratory rate, concentrated urine (increased specific gravity), cool and clay. SAFETY- risk for ORTHOSTATIC HYPOTENSION, risk for falls and overload
15
Q
isotonic fluids action
A
increases blood pressure, NS goes with blood products. DO NOT give to HTN, cardiac or renal d/s can cause FVE, HTN, or hypernatremia (ones with sodium)
16
Q
types isotonic fluids (4)
A
NS, LR, D5W, D5 1/4 NS
17
Q
hypotonic fluids action and types (3)
A
(hypO= Out of vessel) shifts into cells- rehydrates without causing HTN. For those with hx of HTN, cardiac or renal d/s, to dilute hypernatremia. D2.5W, 1/2 NS, 0.33%NS ALERT- watch for cellular edema/ too much fluid to cells can cause FVD in vascular space and decrease BP
18
Q
hypertonic fluids action and types
A
(hypEr= Enter the vessel) Volume expanders
for hyponatremia or severe third spacing. ALERT- monitor for FVE- BP, pulse, CVP. D10Wm, 3 or 5%NS, D5LR, D5 1/2NS, D5 NS, TPN
19
Q
2 types of cancer
A
solid tumors and hematologic malignancies
20
Q
sarcoma
A
solid tumor in connective tissue- bones, cartilage, tendons
21
Q
carcinoma
A
solid tumor in epithelial tissues- line organs- and skin! most common type of cancer
22
Q
hematologic malignancy
A
originate from blood or lymphatic system- leukemia, lymphomas..
23
Q
metastasis
A
ability to travel- can travel by direct invasion, through blood stream or through lymphatic system
24
Q
cancer primary prevention
A
no smoking, exercise good nutrition, maintain normal weight, limit or eliminate alcohol, vaccine for viruses, avoid exposure to carcinogens
25
secondary prevention for cancer (female)
screenings to detect early. Breast SE day 7-12, clinical breast exam q3yrs 20-39 and q1yr >40. paps q3yr >21 y/o. mammogram starting at 40 y/o
colonoscopy and fecal occult blood > 50 y/o
26
secondary prevention for cancer (male)
breast self awareness, yearly testicular exam, monthly self exam, (majority ages 15-36!!) teach testical self exam early. Digital rectal example, PSA, and fecal occult blood annually after 50. colonoscopy at 50 and q10yr.
27
Cachexia
extreme wasting and malnutrition (used in cancer)
28
Cancer symptoms think
```
Caution
Chang in bowel/bladder habits
A sore that does not heal
Unusual bleeding or discharge
Thickening or lump
Indigestion or difficulty swallowing
Obvious change in wart or mole
Nagging cough or hoarseness
Also- weight loss, FATIGUE, pain
Fever- first in leukemia and lymphoma (infection!
)
```
29
Cancer can invade bone marrow causing (3)
Anemia -hypoxia risk
leukopenia- infection risk
thrombocytopenia- bleeding risk
30
rupture of innominate artery
bleeding massively from the trach- call Dr, OR ASAP
31
sputum specimen
get first thing in the morning, sterile technique! sterile specimens. have client rinse out mouth first to decrease mouth bacteria, don't let mouth touch the sterile cup. if they have a trach- get the sputum specimens from the trach.
32
total laryngectomy
removed vocal cords and epiglottis- have a permanent trach. can use an electrolarynx or Blom- Singer to talk. they cannot whistle, drink through a straw or swim, can smoke through the trach.
33
suctioning a trach
hyper oxygenate before and after, sterile procedure, stop advancing at resistance/ cough, intermittent suction on the way out for no longer then 10 seconds, monitor HR/arrythmias, can stimulate the vegas nerve and cause HR to drop
34
adjuvant
using two complimentary treatments together- like chemo and radiation
35
neoadjuvant
time specific therapies- one is done before the next- like surgery to remove tumor followed by chemo.
36
Grade of cancer
1-4 based off of how different cells are from the original cells- more different- more aggressive.
37
TNM system
cancer staging- TNM
| Tumor size, lymph Node involvement, Metastasis?
38
mastectomy with lymph node removal
protect that side for the rest of life- no constriction, no: watch, purse on that side, IV, BP, sunburn, nail biting, elastic blouses, watch small cuts
39
brachytherapy
internal radiation close to cancer. both pts will emit radiation
unsealed- IV or PO, radioactive for 24-48 hrs and radioactive body fluids
sealed or solid- body fluids not radioactive, can be temp or permanent implants
*safe to assume all emit radiation!!!
40
nursing internal radiation precautions
time, distance, iron shield. rotate assignment daily, nurse should only get one radiation implant pt a shift, private room, film badge, wear gloves with risk of exposure to body fluids, mark room with instructions for specific isotope, prevent dislodgment- bed rest, fiber restriction, cath to prevent bladder distention
41
internal radiation pt visitors
limit, visitors must stay 6 ft away, cannot visit for more than 30 minutes. no visitors who are < 16 years old or pregnant.
42
after internal radiation precautions
client is immunosuppressed. stay 6 ft away from people for up to 10 days, close lid and flush toilet 2-3 times
43
radiation implant dislodgement
gloves, forceps, tongs- put in lead lined container and call radiation dept- leave it in the room
44
external radiation
AKA tele therapy or external beam radio therapy with a cobalt or gamma machine- pt is not radioactive- do not wash off markings or put lotion on them, protect the site from UV for 1 year
45
sxs from external radiation
#1 c/o fatigue, location and dose related. erythema, shedding, altered taste, and pancytopenia (all blood components decreased)
46
calcitonin
hormone made by the thyroid gland. it takes ca from blood and puts it back into bones- so it decreases serum calcium. the drug calcitonin is given to pts with osteoporosis. need iodine to make hormones
47
don't give beta blockers to
asthmatics or diabetics. hides the symptoms of hypoglycemia and can cause an asthma attack
48
parathyroid think
calcium. parathyroid secretes PTH (parathyroid hormone) which pulls calcium from bone and deposited it in the blood- increases serum calcium
49
hyperparathyroidism=
hypercalcemia= hypophosphatemia
too much PTH, serum ca is high and phosphate is low- client is sedated (Ca acts as a sedative) fix with partial parathyroidectomy
50
pheochromocytoma
benign tumors in adrenal medulla (on top of kidneys) that secrete boluses of epi and norepinephrine causing increase BP, pulse, flushing, HA, palpitations- check the catecholamine levels (vanilla test or metanephrine test, 24 urine collection) DO NOT palpate ABN, can cause bolus and severe HTN
51
4 major actions glucocorticoids
adrenal cortex steroid. Think MI-FI Mood, Immunosuppressed, Fat, Insulin
1- change mood
2- alter defense mech- suppress immune system
3- Breakdown fats and proteins -to glucose
4- inhibit insulin- hyperglycemia- monitor glucose
and don't let them share room with infected b/c of suppressed immune system
52
Graves
hyperthyroid
53
addisons
insufficient steroids/ adrenocorticoids- glucocorticoids, mineralocorticoids (aldosterone), and sex hormones
54
aldosterone drug name
fludrocortisone
55
glucocorticoid administration
prednisone- give twice a day, 2/3 of dose in morning and 1/3 of dose in evening (for addisons disease)
56
addisons symptoms
Think no aldosterone or glucocorticoids. no aldosterone to help retain water and Na, so lose water and Na, retain K, hypotension; no glucocorticoids to make glucose or inhibit insulin, so hypoglycemic, confused, GI probs, fatigue, and skin discolorations- hyper pigment or depigment (vitiligo)
57
cushings
too many steroids- glucocorticoids, mineralocorticoids, sex hormones
58
magnesium and calcium think
sedatives/ muscles, loose, flaccid muscles, arrhythmia, decreased LOC, DTRs, pulse and respirations
59
normal magnesium
1.3-2.1 mEq/L
60
normal calcium
9.0- 10.5 mg/dL
61
low magnesium or calcium
tight rigid muscle tone, risk for seizure, stridor/ laryngospasm, chvosteks and or trousseaus sign, arrhythmia, DTRs increased, swallowing probs
62
calcium gluconate
```
given IVP very slowly (max 1.5-2mL/min)
For hypermagnesium (antidote), or hypocalcemia
```
63
hypermagnesium causes, tx
renal failure or antacids (tums have magnesium) tx: vent if resp depression, dialysis if kidney prob, calcium gluconate antidote
64
hypercalcemia cause and tx
hyperparathyroid (too much PTH), Thiazides (retain Ca), immobilization- bear weight to keep Ca in bones, fluids to prevent kidney stones, DVT, sodium phosphate- inverse relationship, steroids, phosphorous foods, calcitonin, vitamin D
65
hypomagnesium cause and tx
diarrhea, alcoholism- give Mg but monitor kidney fin!, seizure precautions, eat magnesium
66
foods high in magnesium
spinach, mustard greens, summer squash, broccoli, halibut, turnip greens, pumpkin seeds, peppermint, cucumber, green beans, celery, kale, sunflower seeds, sesame seeds, flax seeds
67
hypocalcemia cause and tx
hypoparathyroidism, radical neck dissection, thyroidectomy (all not enough PTH)
Vit D, phosphate binders (sevelamer, calcium acitate), IV Ca- give slowly with pt on heart monitor
68
Na think
Neuro! neuro changes when sodium is high or low
69
hypernatremia= dehydration cause
feeding tube, hyperventilation, heat stroke, DI. give fluids, restrict Na, Daily weights, I&O, lab work
70
hyponatremia= Dilution cause and tx
Replacing fluid with only water, psychogenic polydipsia, D5W, SIADH
client needs salt, not water, give hypertonic saline if having neuro probs- 3 or 5% NS- very dangerous, messes with brain and can throw into FVE
71
hypernatremia symptoms
neuro and dry mouth, thirsty, swollen tongue
72
hyponatremia symptoms
neuro and HA, Seizure, Coma
73
hyperkalemia cause and tx
kidney probs, aldactone (spironolactone-retain K),
dialysis if kidney prob, calcium gluconate for arrhythmia, glucose and insulin, Kayexalate (sodium polystyrene sulfonate)
74
hyperkalemia ECG changes
bradycardia, tall peaked T waves, prolonged PR intervals, flat or absent P wave, widened QRS, conduction blocks, v fib
75
hypokalemia ECG changes
U waves, PVCs, v tach
76
hyperkalemia symptoms other than ECG
first muscle twitching, then weakness, then flaccid paralysis- then life threatening arrythmia
77
hypokalemia symptoms (not ECG)
muscle cramps and weakness then life threatening arrythmias
78
hypokalemia cause and tx
vomiting, NG suction, diuretics, not eating
79
potassium supps
GI upset with PO- give with food. IV always on a pump, mix well- settles, never IVP, burns during infusion, Assess kidneys/ urinary output before giving
80
potassium and metabolic A/B imbalance
metabolic acidosis= hyperkalema
| metabolic alkalosis= hypokalemia
81
rule of 9s
head and neck-9
each arm-9
each leg-18
front-18, back-18
82
consensus formula
aka parkland formula
4mL LR X Kg X % burned= total for 24 hours
1st 8 hours- 1/2
next 16 hours- 1/2
titrate to 0.5mL/kg/hr urinary output (1mL for kids)
83
prealbumin
most sensitive indicator for nutritional status/ nitrogen balance
84
diet for burns
protein and vitamin C- always for max nutrition
85
meds to prevent GI stress ulcer
curlings ulcer
antacids= HYDROXIDE (a base!)-aluminum hydroxide, mag hydroxide (milk of magnesia). liquid on empty stomach at bedtime, when stomach empty more risk of acid on the ulcer, protects overnight.
H2 antagonist= DINEs, ranitidine, famotidine..-take at night to inhibit acid secretion
proton pump inhibitors= ZOLE- pantoprazole, esomeprazole..take before first meal
Sucralfate- barrier over ulcer. 1 hr b4 meals and at bedtime, empty stomach, with glass of water- no other meds at same time.
86
tetanus toxoid
booster- takes 2-4 weeks for body to make antibodies- active immunity. give with burns unless overdue for booster or don't know- then give immune globulin (antibodies)-passive immunity
87
circumferential burn
circulatory checks- pulse, color, temp, cap refill
| if bad- escharotomy or fascitomy to relieve pressure
88
brown or red urine post burn
myoglobin from damaged tissues- can clog kidney- call dr. may give Mannitol to flush (diuretic) also given for increased ICP. EXCEPTION- normally want to give fluids not diuretics to burn pt- trying to save kidneys
89
burns and potassium
tissue damaged- k leaks out of cells, hyperkalemia
90
enzymatic debridement
sutilains or collagenase- eat dead tissue
| not for face, if PG, over large nerves or if area is opened to a body cavity.
91
mycin drugs
cause nephrotoxicity and ototoxicity- monitor BUN, creatinine and hearing
92
autograft
(burns) graft from own skin, dressing at donor site until stops bleeding, then open to air, can re harvest from same donor site every 12-14 days in healthy pt
93
electrical burn
heart monitor for 24 hours, at risk for v fib, c collar until cervical fracture is r/o
94
Cardiac output assessment
focused assessment- do anytime a hear rhythm change!
| LOC, Chest pain?, wet lungs, skin cold and clammy or warm and dry?, Urinary output, peripheral pulses
95
what is coronary artery disease
broad term that includes chronic stable angina and acute coronary syndrome (MI and unstable angina)
96
drugs for chronic stable angina
nitro- dilates all vessels, decreased BP, ASA
and BLOCK from happening again (prevention) with BB and CCB!
beta blockers (prevention)- decrease BP, pulse and contractility
ca channel blockers (prevention)- dilates arteries, including coronary arteries and decreases BP
don't leave a hypotensive client- unstable!
97
given to protect kidneys from iodine dye
acetylcysteine preprocedure; iodine based dye makes them feel warm and flushed and palpitations are normal- cardiac cath uses dye!
98
Triad MI symptoms
in women with MI- indigestions/ abdominal fullness, chronic fatigue and SOB. women also c/o pain btwn shoulders, aching jaw or choking sensation
99
#1 sign MI in elderly
SOB. they may faint or have a behavior change
| anytime ELDERLY + BEHAVIOR CHANGE = PROBLEM could be UTI, but r/o life threatening causes first
100
MI labs
troponin most sensitive and specific- elevates 3-4 hours and remains elevated for 3 weeks
myoglobin increases within one hour and peaks in 12 hours- not specific for diagnosis, but can be used to R/O
101
troponin levels
troponin T < 0.10 ng/ml
| troponin I < 0.03 ng/ml
102
digoxin
normal level- 0.5-2 ng.ml
increases contractility and decreases heart rate (check apical pulse) =increase CO
toxicity GI probs then arrhythmia and vision change
103
apical pulse location
5th intercostal , left midclavicular
104
fluid retention, think
heart problems (heart failure) report weight gain of 2-3 lbs (1-2 kg)
105
loss of capture
when pacemaker fires but does not result in a heart contraction
106
failure to sense
when pacemaker fires at inappropriate times when it is not needed
107
cardiac tamponade
blood fluid or exudates have leaked into pericardial sac resulting in compression of heart. hallmark signs: INCREASING CVP with DECREASING BP. NARROWED Pulse Pressure=CARDIAC TAMPONADE
WIDENED PP= INCREASED ICP
decreased CO= worry shock
TX- pericardiocentesis
108
Pulse pressure
difference btwn SBP and DBP.
Narrowed= Cardiac Tamponade
Widened= Increased ICP
these are changes from baseline
109
depression nursing interventions
help with self care during acute stage. help them experience accomplishments
no compliments, thoughts slowed- slow communication or give silence
prevent isolation- Seek them out! Interaction helps
110
manic interventions
decrease stimulation, no group- one on one, brief frequent contact with staff, writing activity good. walk with them during meals- use finger foods. weigh daily, don't get manipulated, set limits and remove hazards
111
schizophrenia interventionsq
decrease stimuli, observe frequently w/o looking suspicious, orient frequently, keep conversations real world, they have concrete thinking and lots of communication probs (echolalia, neologism, word salad) "i don't understand" may be LOA X4 and still have delusions or hallucinations
112
paranoid
trust issues- be reliable, be honest, build trust. ID meds, don't mix, don't be overly friendly/ touching. consistent nurses, no competitive activities- they have an abnormal anger response- tantrums- hypersensitive. all consuming jealousy- everyone has it better
113
alcohol withdrawal intervention
DTs (stage 2 and 3 delirium) keep the lights on
stage 1 and 2- walk and talk to them- keep reorienting
give anxiolytics- may have a tolerance q2h. thiamine injections, multivitamins and magnesium
114
alcoholic signs and symptoms
peripheral neuritis/impotence (kills nerves- low B vit effects)
kills GI- liver and pancreas probs, gastritis
diurese- lose mg and K
complications- korsakoffs (time disorientation- confabulate), wernickes (moody, tire easily)
115
panic attack
stay 6 feet away and use simple words. symptoms will peak within 10 minutes. have clients journal to reduce anxiety and identify triggers, peaks and valleys.
116
hallucinations interventions
warn before you touch, don't say they, involve in an activity- out of hallucination and into real world. elevate HOB, turn off TV, and offer reassurance
117
ECT pre and post procedure
for severe depression and manic
NPO, void, atropine to dry secretions, succinylcholine chloride to relax muscles, baseline injuries
post- on side, don't aspirate, stay with client, assure family temporary memory loss is expected, reorient over and over, involve in day's activities ASAP
118
amount of fluid replacement in glomerullonephritis
24 hour loss + 500 mLs for insensible loss
| kidney damaged so not excreting, careful of FVE
119
anasarca- when happens and patho
total body edema- seen in nephrotic syndrome-
inflammatory response produces large holes in kidneys lose large amount of proteins. no protein in the blood so blood goes into tissues, bp decreases. the only kidney patient will increase protein intake in
120
fixed specific gravity
seen in renal failure- kidney lose ability to concentrate and dilute urine. do a Fluid Challenge- give bolus of 250 or more NS and the specific gravity will not change.
121
acute renal failure oliguric phase- worry about
FVE and hyperkalemia- retaining fluid and potassium. UO is decreasing to 100-400mL/24 hrs
122
acute renal failure diuretic phase- worry about
FVD and hypokalemia. sudden increase in UO, excreting fluid and potassium
123
assessing patency of dialysis access
palpate a thrill and auscultate a bruit
| feel thrill- can purr, hear bruit- turbulent blood flow
124
symptoms of peritonitis from peritoneal dialysis
abdominal pain and cloudy effluent--- cloudy effluent with any peritoneal dialysis= infection! should be clear, stat color
125
diet for client on peritoneal dialysis
fiber- abdominal fluid is decreasing peristalsis
| protein- lose protein in exchange bc holes in peritoneum are large
126
CCRT
continuous renal replacement therapy- done in ICU, never > 80 ml fluid out of body at one time- less stress on cardiovascular system. for pt with fragile cardiovascular status and acute renal failure
127
urolithiasis
means stone in ureter- renal calculi
symptoms: pain with N/V, WBC in urine, hematuria- urine test for RBC
tx with ketorolac, ondansetron and hydromorphone, increase fluids
128
extracorporeal lithotripsy
extracorporeal shock wave lithotripsy (ESWL) high energy shock wave to break kidney stones into sand- will come back with foley, want to see sediment in bottom of bag.
129
Glasgow coma scale- 3 responses
measures LOC
Eye opening, motor response, verbal response. 0 means no response. total can be 3-15, anything less than 13 bad, requires full neuro assessment hourly
130
Babinski reflex
normal for children under 1 year/ not walking, is fanning toes
plantar (curled toes) normal for adult
131
documenting reflex
(0) absent, (2+) normal, (4+) hyperactive. must have denominator to show scale used. so normal= 2+/4+
132
CT
computerized tomography - may use die (consent), picture slices/ layers, keep head still and no talking
133
MRI
magnetic resonance imaging- better than CT, not usually a dye, uses a magnet. no jewelry, pacemaker, credit cards, old tattoos may have lead, can't talk or hear others in tube. teeth fillings okay
134
Cerebral Angiography
angiography- DYE (consent), x ray of cerebral perfusion
iodine based dye- hydrate, void, peripheral pulses, groin prepped, watch BUN, retaining, output hold metformin, warmth in face and metallic taste
after- bed rest 4-6 hours, monitor femoral bleed, possible embolus,
135
ECG
electroencephalography- records electrical activity of brain to dx seizure d/o, screen for coma/brain death, and to dx sleep d/o. no caffeine, no sedatives- but normal breakfast so no blood sugar drop. baseline EEG lying quietly- then hyperventilate or stimulate coma patient
136
lumbar puncture
to obtain spinal fluid to analyze for blood, infection, and tumor cells or measure pressure with manometer, admin drugs. position over bedside table with head down. CSF should be clear and colorless
after- lie flat or prone for 2-3 hrs, increase fluids, HA is common- increases with increase HOB, for HA: bed rest, fluids, pain med and blood patch- do not do puncture if known increased ICP
137
normal ICP
0-15 mm Hg
138
early symptoms of increased ICP
earliest- change in LOC, slurred slowed speech, delay in response to verbal suggestion, slow to respond to command, increased drowsiness, confusion and may have HA, vomiting, pupil changes
139
late signs of increased ICP
worse change in LOC progressing to stupor and coma
| Cushing's Triad, posturing and may have HA, vomiting,and or pupil changes
140
Cushing's triad
changes in vital signs seen with increasing ICP
Systolic HTN with widening pulse pressure, slow, full, bounding pulse, irregular respirations- change in pattern like cheyenne stokes or ataxic (containing apnea)
141
posturing types
response to painful/ noxious stimuli when motor response centers are compromised
deCORticate- towards the CORE, arms flexed inward and bent in toward body, legs extended
Decerebrate- all 4 extremities in rigid extension- really bad and burning calories
142
complications of increased ICP
brain herniation- obstructs blood flow to brain
| DI and SIADH (with head injury)
143
Tx of increased ICP
maintain O2, isotonic saline, inotropic agents (dobutamine and norepinephrine), monitor BP and HR closely, want to decrease ICP without decreasing cerebral perfusion. keep temp < 100, elevate HOB, keep head in midline to promote drainage from head, monitor ICP when turning, avoid straining (restraints, no blowing, hep flexion, bowl or bladder distention) limit suctioning, space out nursing interventions, monitor Glasgow coma, cushing triad, phenobarbital to decrease cerebral metabolism, osmotic diuretic (mannitol) steroids to decrease cerebral edema
144
ICP monitoring
ventricular catheter monitor or subarachnoid screw
| risk for infection, no loose connections, keep dressings dry to decrease bacterial ability to travel through
145
neuro- when thinking intubate?
when glasgow coma is less than 8, think intubate
146
meningitis
inflammation of spinal cord or brain
bacterial- transmitted through respiratory system-DROPLET PRECAUTIONS, very contagious, very deadly- immunize before college
Viral transmitted by feces and requires CONTACT PRECAUTIONS seen more in infants and children
147
symptoms of meningitis
chills/ fever, severe HA, N/V, nuchal rigidity (stiff neck), photophobia
148
meningitis tx
steroids, antibiotics (bacterial), analgesics
DROPLET PRECAUTION- Bacterial
CONTACT PRECAUTION- Viral
149
generalized seizure
AKA non focal- involves entire brain and initial manifestation is Loss of Consciousness
150
Partial seizure
AKA focal- involves a local area of brain- symptoms vary widely. simple means no loss of consciousness, complex means impaired consciousness, confused, unable to respond
151
tonic- clonic
AKA grand mal
tonic- lose consciousness and completely rigid
clonic- jerking, muscles tense and relax
152
myoclonic seizure
sudden, brief contractions of a muscle or group of muscles
153
absence seizure
AKA petit mal characterized by brief loss of consciousness
154
anticonvulsants for seizure
rapid acting- lorazepam
long acting- phenytoin or phenobarbital, have toxic SE so used smallest effective dose, monitor drug levels for tox through lab values, abrupt withdrawal can cause seizure
155
autonomic dysreflexia
upper spinal cord injury (above T6), aka hyperreflexia. characterized by severe HTN and HA, bradycardia, nasal stuffiness, flushing, sweating, blurred vision, anxiety- can cause stroke
sit client up to decrease BP, put in catheter for distended bladder, removed impaction (constipation), look for skin pressure/ pain, cold draft...
156
where would you see bleeding with basal skull fracture
EENT, ears, eyes, nose, throat
157
difference in open/ closed skull fracture
whether the dura was torn
| surgery for depressed skull fractures (skull depressed into brain), don't normally need surgery for non depressed
158
NO Smoking when?
Anytime NPO. smoking increases stomach secretions- increase risk for aspiration. Also increases stomach motility- will effect an Upper GI series test- which you are NPO for as well (after midnight) also no gum or mints
159
go lytely
polyethylene glycol, put in freezer to make extra cold- can tolerate better, no straw (air), causes nausea- antiemetic- used for colon prep, colonoscopy
160
McBurney's Point
Lower right quadrant -location of appendix and pain with appendicitis (initially generalized pain, eventually localizes here with rebound tenderness, N/V (after abdominal pain), anorexia)
161
clotting times
therapeutic INR 2-3
aPTT 30-40, >110 need antidote- protamine sulfate
normal PT 11-13 seconds, therapeutic is 1.5-2.5X normal
162
D dimer
blood test that increases in presence of blood clots. look at to dx pulmonary embolism, but if had surgery will be increased from clotting at incision site- VQ scan best to dx PE
163
crutches with stairs
up with good leg, down with bad leg
164
cane
use on strong side of body
165
LVN/ LPN delegation
Cannot plan or assess independently or care for unstable pt, but do not assign them anything a UA can do. they can reinforce teach
166
full chemo precautions
chemo/ isolation gown, 2 pairs of chemo gloves, goggles and or mask if splashing or inhalation can occur (with drugs or body fluids) YELLOW waste container or waste bag. excretion 3-7 days
167
PPE order
mask, gown, gloves, goggles
168
vesicant
type of chemo drug that causes extravasation if infiltrates. stay with any client receiving vesicant drug, if extravasation happens, stop infusion, cold pack, follow extravasation protocols
169
infection prevention cancer pt
private room, limit visitors, change dressings and IV tubing daily, cough and deep breathe, no fresh plants, bathe moist areas twice/day, wash hands after touching person or pet, avoid or wash really well fresh fruits and vegetables, drink only fresh water (can be out only 15 minutes), teach come to hospital with temp >100.4
170
ANC
absolute neutrophils count. watch on cancer patients, indicates how well they can handle an infection. normal is 2200-7700
171
Neutrophenic precautions
infection prevention + V/S q4h, private room with closed door and posted sign, antimicrobial soap for HH, no invasive tx (IM injection, rectal exam/meds, indwelling caths, NG (when possible)), limit acetaminophen
172
CMV
cytomegalovirus- very common herpes virus, dormant/ asymptomatic in healthy people. blood products for immunosuppressed is tested for it, they need CMV negative blood or CMV "safe"= blood with CMV goes through leukoreduction
173
patient has symptoms of being pregnant is called
presumptive signs- ex: amenorrhea, N/V, urinary frequency or breast tenderness. signs that can be observed by the Dr are probable sings- unless they are positive signs like a heartbeat
174
can hear baby heartbeat on doppler at ? weeks
10-12 weeks
| fetoscope at 17-20 weeks
175

176
viability
24 weeks
177

178
naegele's rule
due date estimator, first day of LMP, add 7 days, subtract 3 days, add 1 year. accurate within 2 weeks
179
increase calories and protein by how much during pregnancy
increase calories by 300/day AFTER first tri (500 if adolescent). 500 calories during breastfeeding
increase protein from 40-45 (normal) to 60
expect to gain 4 lbs in first tri
180
to prevent neural tube defects in baby
take 400 msg/day of folic acid. spina bifida is an example of neural tube defects
181
exercise rule during pregnancy
do not let your HR > 140. your CO and uterine perfusion will decrease. no high impact exercise- rec walking and swimming
182
fetal HR
120-160, 110-120 worry, <110 panic
183
need RBC when H and H
hgb of 8 and Hct of 24%
184
lightening
sign of labor- about 2 weeks before term, presenting part of fetus descends into pelvis, pt can breathe easier and is less congested but urinary frequency (last had in 1st tri) returns
185
engagement
largest presenting part in pelvic INLET. will block the cord from prolapse when membranes rupture. ROM- check fetal heart tones!!!
186
fetal stations measures
measured in cm and measures relationship of presenting part of the fetus to the ischial spines of the mom
187
labor- when go to hospital
5 minutes apart or ROM
188
Non stress test
(NST) want to see 2+ accelerations of 15+ WITH FETAL MOVEMENT (pt push button when feel mvmt). acceleration is abrupt increase from baseline that lasts 15+ seconds and come back to base within 2 minutes. recorded for 20 minutes
189
biophysical profile test (BPP)
done by U/S, each parameter counts as 2 pts- want 8-10/10. done in last tri or earlier in high risk, also high risk may do every 1-2 wks in 3rd tri. measures over 30 minutes: reactive NST, muscle tone (1 flex/extend), movement (3 times), breathing (1 mvmt), amniotic fluid adequate
190
contraction stress test
CST. oxytocin challenge test. oxytocin is very dangerous- one on one observation. determines if baby can handle stress of contraction, want non reactive. do not want to see late deceleration= uterine/placenta insufficiency. want a negative test, rarely done before 28 wks and RESULTS GOOD FOR ONE WEEK, positive= hospitalization
191
three types of decelerations
Early- okay- hypoxia from fetal head compression
late- bad- uteroplacental insufficiency
variable- bad- umbilical cord compression- move patient
192
epidural complication
Can have acute severe hypotension. give bolus 1000mL NS or LR before epidural and monitor BP- put in semi fowlers on side to prevent compression to vena cava.
193
when to turn off oxytocin
contractions too frequent or too long (want 1 every 2-3 minutes lasting 60seconds), or any signs of fetal distress- like late decels. TURN OFF not down
194
post partum lochia
Dark red (RUBRA) 3-4 DAYS
Pink/brown (SEROSA) 4-10 days
white/ (ALBA)- 10-28 days or up to 6 weeks anything abnormal (amount, color, smell) decrease activity and call doctor. goes backward to rubra, call 911
close no larger than a nickel
195
peripad rule
do not saturate more than 1 peripad per hour. more think hemorrhage
196
kangaroo care
should be done for 1 hour at least 4 times a week. bonding for baby: stabilizes HR, improves O2 sats, regulates temp, conserves calories
197
dx of early post part hemmorrhage
more than 500 mL blood loss in first 24 hours AND 10% drop in hematocrit from admission. late is anytime after 24 hours to 6 weeks.
meds: oxytocin, methylergonovine maleate, carboprost
198
mastitis tx
usually 2-4 wks pp from staphylococcus
bed rest, support bra, feed frequently from affected side first, heat and pain meds, penicillin drug of choice- allergy? erythromycin. take antibiotic after feeding
199
apgar
done at 1 and 5 minutes look at HR respirations, reflex irritability, color. want at least an 8
200
drugs at birth
erythromycin drops or ointment for eye prophylaxis from gonococcus and chlamydia, phytonadione (vit k) for clotting factors to vastus laterals
201
pathologic jaundice
jaundice within the first 24 hours of life. usually means Rh/ ABO incompatibility. after 24 hours is physiological jaundice (hyperbilirubinemia) normal hemolysis of excess RBCs, liver immaturity
202
Rh sensitization or Rh factor occurs when?
only with Rh (-) mom and Rh (+) baby, get exposed with first baby and develop antibodies (become sensitized) with subsequent pregnancies babies will have increased immature RBCs (making more because getting attacked- this is called Erythroblastosis fetalis)
203
Coombs
indirect coombs- test to mom measures antibodies for Rh
Direct Coombs- done on cord blood to count antibodies on RBCs.
with Rh + baby and sensitized mom will do frequent ultrasounds and deliver when baby stops growing.
204
Rho (D) immune globulin (RhoGAM) RULE
must give before antibodies form. given at 28 wks (just in case any mixing of blood, protects current baby) and anytime bleeding episode/ ANY chance mixing of blood. also given within 72 hours after birth (protects future baby) give after car wreck, before abortion or amniocentesis, ectopic pg, percutaneous cord blood
205
cystic fibrosis
usually discovered by salty kiss to baby or meconium illeus. losing salt, have steatorrhea. causes thick sticky mucus everywhere, need pulmonary txs, pancreatic enzymes get stuck, need enzymes with food (don't digest fat well), need water soluble vitamins, autosomal recessive d/o (BOTH parents).
206
celiac d/s diet
lifelong genetic malabsorption d/o to gluten. canNOT eat BROW Barley, Rye, Oats and When
Can have rice, corn and soy.
207

211
hypoglycemia sxs and tx
cool, clammy, confusion, shaky, HA, nervous, nausea, increased pulse- give simple sugar (soda, milk, juice) then give complex carb with protein like crackers with cheese. AVOID fat- it delays absorption of sugars-
212
drugs to treat nephrotic syndrome
Diuretics to remove excess fluids
ACE Inhibitors - to block aldosterone (being excreted bc low fluid vol in vascular spaces- third spacing)
Prednisone to decrease inflammation and shrink holes in kidneys to stop losing protein
Lipid lowering drugs (cholesterol and lipids increased due to liver making albumin to replace whats lost
Anticoagulation therapy for 6 months- loss of plotting factors
increase protein- losing it.
common is albumin to pull fluid out of tissues with lasix to flush it out.
213
how is protein metabolized, what happens if liver broken?
protein is broken down into ammonia, the liver converts the ammonia to urea and the kidneys excrete the urea. so in liver failure ammonia builds up in blood- - decrease protein and salt in diet, lactulose and cleansing enemas to get rid of GI bleed and ammonia- protein in the blood is getting turned into ammonia...
214
hypothyroid looks like? sxs?
hypothyroid looks like depression. no energy, fatigue, no expression, depressed mood, slow/slurred speech, weight gain, GI slow, always cold, amenorrhea. may be immobile. tend to have coronary artery d/s (CAD)
215
hydatidiform mole Dx, tx/follow up
uterus grows too fast, no FHT, bleeding- confirm with U/S, D&C to remove. follow up- will do chest X-rays to determine metastasis, will measure hCG weekly until normal and then every 2-4 weeks, then q1-2 months for 6 mos to a year- do not get pregnant during this time!
216

severe pre-eclampsia. Hemolysis, Elevated Liver enzymes, Low Platelet sxs- RUQ pain, N/V malaise
218
cystic fibrosis think, electrolyte? dx test?
thick sticky mucus everywhere- main probs respiratory and GI, sweat sodium chloride, hyponatremia. test is sweat chloride test. newborn doesn't pass first stool (meconium illeus) is first sign- too thick and sticky. high fat, calorie, protein diet and water soluble vitamins (ADEK)
219
CDU intermittent/ continuous bubbling, what is okay and what is not?
continuous gentle bubbling expected in suction chamber. water seal chamber can have intermittent bubbling, but never continuous bubbling in water seal chamber- leak, call dr.
220
heart failure tx- meds, diet monitor
standard is ACE I's and ARBS (watch K), will go home on ACEI and/or Beta B. Also, Dig, diuretics, lo(
221
pulmonary edema cause and tx
heart, kidney prob and/or rapid fluid admin. have pink frothy sputum (like TB). keep O2>90%, diuretics, nitro, morphine, nesiritide (bnp), upright position
222
nephrotic syndrome tx (diet, 5 meds)
diet- low sodium, high protein (even though kidney problem, losing too much protein)
Give albumin to pull fluid back into vessels and diuretic to get rid of the excess fluid, ACEI to block the aldosterone that is causing retention, prednisone reduce inflammation and hopefully shrink hole too small for protein leak, lipid lowering drugs for hyperlipidemia, anticoagulation therapy for up to 6 months. dialysis
223
signs and symptoms of nephrotic syndrome (urine, blood)
proteinuria, hypoalbumineia, anasarca, hyperlipidemia, prone to clots
224
catheter for peritoneal dialysis
tenckhoff catheter
225
types of peritoneal dialysis
continuous ambulatory - 4 times a day, everyday
| continuous cycle- at night
226
miscellaneous signs of increasing ICP
head injury/ problem with HA. changes in pupil and pupil response (fixed, dilated), projectile vomiting- pressure in vomiting center of the brain
227
Increased ICP Tx
maintain O2, maintain adequate perfusion so don't allow hypotension or bradycardia, isotonic saline and inotropic agents, keep temp below 100 F (increased temp increases metabolism- maybe cooling blanket, hypothermia to decrease cerebral edema), elevate HOB, head midline position avoid anything that could increase ICP or cerebral metabolic demand- maybe barbiturate induced coma, mannitol, steroids, ventricular cath or subarachnoid screw
228
sxs of pancreatitis
pain that increases with eating- mass (swollen pancreas) in upper middle to left side, abdominal distention /ascities- losing protein rich fluids and blood- rigid board like abdm with culling sign or gray turns sign, fever, N/V, Jaundice. hypotension (bleeding/3rd spacing!)
229
pancreatitis dx blood work
lipase and amylase increase
WBC increase, blood sugar increase (pancreas makes insulin!), liver enzymes increase so now bleeding times increase and bilirubin increase. h/h may go up or down- bleeding/ dehydrated
230
long term use of steroids can cause
DM or cushings
231
treatment for pancreatitis (5 meds)
NPO, NG to suction and bed rest
control pain- PCA narcotics/ fentanyl patches
steroids for inflammation, anticholinergics to dry up, GI protectants (dines, zoles, antacids (hydroxides), insulin, maintain F&E balance and nutritional status= start with TPN, daily weights, no alcohol and AA (unless the cause is gallbladder d/s)
232
4 functions of the liver
detox the body,
helps blood clot
metabolizes drugs and proteins
synthesizes albumin
233
cirrhosis patho and symptoms- blood work
liver scarring causes hepatic portal hypertension
firm nodular liver, abdominal pain, ascites, change in bowel habits, chronic dyspepsia (GI upset), splenomegaly, jaundice
Blood- elevated liver enzymes, low albumin (not synthesizing), anemia (not clotting)
worry about BLEEDING
234
how is cirrosis dx, how is the procedure done?
first U/S, CT, and/or MRI
liver biopsy to confirm- worry about bleeding!
pre procedure VS and clotting times, position supine, no pillow, right arm behind head
tell to exhale and hold breath to get diaphragm out of the way
lie on right side post procedure and VS
235
cirrosis tx
antacids, vitamins, diuretics, I&O, daily weight, rest (tired from toxins), bleeding precautions, measure abdominal girth and maybe paracentesis for the ascites, skin care for jaundice, avoid narcotics- can't metabolize, low protein diet and low salt
236
hepatic coma caused by
too much ammonia- damaged liver cannot convert the ammonia to urea or make albumin.
237
sxs of hepatic coma
minor mental and motor probs, difficult to arouse
asterisks (flapping hands), handwriting change, reflexes decrease (sedative), EEG is slow, fetter (ammonia breath) liver problem pts tend to be GI bleeders (hepatic portal HTN- increase pressure along whole GI tract) and protein in blood will increase ammonia
238
tx for hepatic coma
lactulose, cleansing enema (get the GI bleeding blood out), decreased protein diet, monitor serum ammonia
239
treatment for esophageal varices
replace blood, VS, CVP, oxygen (anemic/bleeding)
Octreotide (reduces hepatic HTN)
Ballon Tamponade to put pressure on site (Blakemore- scissors at bedside),
cleansing enema to get rid of blood, lactulose to decrease ammonia, aline lavage to get blood out of stomach
240
gastroscopy
EGD, endoscopy- used to dx peptic ulcer
NPO 8 hrs before, sedated, NPO until gag reflex returns (tickle back of throat), watch for perforation- pain, bleeding, having trouble swallowing- check temp q15-30 mins for 1-2 hrs- sudden spike=perforation.
warm saline gargle for soar throat
241
upper GI series
looks at esophagus and stomach with dye- also used to dx peptic ulcer, NPO after midnight
242
client teaching peptic ulcer
decrease stress, stop smoking, eat what you can tolerate- avoid temp extremes, spicy, caffeine. need to be followed by a dr for 1 year, takes a long time to heal.
243
gastric ulcer vs duodenal ulcer
gastric- malnourished, pain 0.5-1 hr after meals, food doesn't help but vomiting does- vomit blood
duodenal- well nourished, night time pain common, pain 2-3 hours after meal, eating helps, blood in stools
244
hiatal hernia
hole in diaphragm too large stomach moves up-
sxs- heartburn, fullness after eating, regurgitation, dysphagia (diff swallow)
tx- small frequent meals, sit up for 1 hour after eating, elevate HOB (at home too), surgery- lose weight most important! lifestyle changes, healthy diet
245
foods that empty stomach fast
carbs and electrolytes- avoid foods high in them with dumping syndrome- eat in semi recumbent position and lay on left side after
246
painful breathing like from cracked ribs causes what imbalance
respiratory acidosis- taking shallow breaths
| hyperventilation- respiratory alkalosis
247
rebound tenderness seen in
means peritoneal inflammation- peritonitis
| ulcerative colitis, crohn's d/s, appendicitis

phenylkentouria
PKU- rare inherited d/o can't breakdown phenylanine- in all things protein- must follow diet for life with special supplements
255
cervical spine injury
cervical C1 highest through C8 lowest.
| around 4/5 make difference in ability to breath, speak, some arm movements
256
thoracic spine injury
T1-T12, T5 above is paraplegia, arms and hands okay- trunk down paralysis. T6-12, can control trunk

259
pyelonephritis
UTI in kidneys- causing dull flank pain, N/V, fever
260
rhabdomyolosis
