MT Flashcards
visceral abdominal pain vs somatic abdominal pain
stimulation of visceral pain fibers usually on organs, not localized
stimulation of somatic pain fibers usually in peritoneum, is localized
important meds to ask about in abdominal exams
blood thinners, NSAIDs, narcotics, steroids
order of abdominal physical exam
inspection
auscultation
percussion
palpation
RUQ contents
liver, gb, stomach, si/li

spleen, stomach, si/li
epigastric area contents
pancreas, liver, gb, stomach, si/li
normal bowel sounds
5-34 clicks per minute
high pitched bowel sounds suggest
obstruction
bruits suggest
vascular obstruction
friction rub sounds suggest
inflammation of peritoneal surface of an organ
venous hum sound suggests
increased circulation b/w portal/systemic
where to start w/ abdomen palpation
start farthest from tender area
causes of splenomegaly
portal hypertension, blood malignancies, hematoma, mono
ascites tests
shifting dullness - percuss borders of tympany/dullness and then have Pt lay on side and if it changes (+)
fluid wave - tapping one side of abdomen felt on other side w/ other hand monitoring
mcburney’s point
2 inches medial to R ASIS towards umbilicus
(+) tenderness, appendicitis
rosvings sign
deep palpation in LLQ
(+) tenderness in RLQ, appendicitis
psoas sign
Pt raises R thigh against resistance then lays on left side and extends R leg at hip
+ pain w/ either maneuver, appendicitis
obturator sign
flex Pts R hip w/ knee bent, then internally rotate hip
+ R hypogastric pain, appendicitis
murphy’s sign
palpate under R costal margin then Pt breaths deep
+ sharp pain w/ stop in inspiration, biliary colic
lloyd’s sign
deep percussion down back
+ pain, kidney pathology
signs of peritoneal inflammation
guarding - contraction of abdominal wall w/ palpation
rigidity - reflex contraction of abdominal wall, Pt stiff
rebound tenderness - more pain when letting go after palpation than pushing in
vindicate
vascular infectious/inflammatory drugs/degenerative iatrogenic/idiopathic cogenital AI/allergic/anatomic trauma endocrine/environment
expected sound on percussion of abdomen
tympanic mostly
GERD Sx
heartburn
regurgitation
dysphagia 30% of Pts
lifestyle modifications for GERD
lose weight (if overweight) avoid triggers avoid large meals wait 3 hours to lay down after meal elevate head of bed by 8 inches
rome 3 criteria for constipation
<3 bowel movements/week straining lumpy/hard stools sensation of incomplete defecation manual maneuvering required to defecate
must have 2+ over 3 months
bistol stool chart
1 - lumps 2 - sausage, lumpy 3 - sausage, cracks 4 - sausage, smooth 5 - soft blobs 6 - fluffy pieces, mushy 7 - watery
main cause of gastroenteritis
viral
viral gastroenteritis two “biggies”
norovirus - sudden onset, 12-48 hours after exposure, usually more vomiting; seen w/ ship/casino outbreaks
rotavirus - most immunized for this, kids either have it or immunized by age 5
bacterial gastroenteritis three “biggies”
salmonella - eating something contaminated
C. diff - most common hospital acquired illness, exposure to antibiotics
E. coli - most common w/ travel
parasitic gastroenteritis one “biggie”
giardia - causes greasy diarrhea (tends to float), bloating, cramping; most common from infected water w/ campers etc
parasitic gastroenteritis one “biggie”
giardia - causes greasy diarrhea (tends to float), bloating, cramping; most common from infected water w/ campers etc
cullen sign
ecchymosis around umbilicus secondary to hemorrhage
grey turner sign
flank ecchymosis secondary to hemorrhage
expected liver size
6-12 cm at mid-clavicular line on the right
expected spleen size
from ribs 6-10 at mid-axillary line on left
heel strike indicates
appendicits or peritonitis
chovstek sign
tap facial N when facial Ms relaxed
(+) spasm = hypocalcemia
hypoparathyroidism causes/Sx
causes: removal, DiGeorge, AI disorder
Sx: hypocalcemia (b/c low PTH) -> seizures, dementia, anxiety, paresthesia, stiffness/spasms, prolonged QT
adrenal insufficiency/addison’s disease causes/Sx
causes: primary usually AI, secondary due to lack of ACTH production
Sx: underproduction of cortisol/ACTH -> low blood glucose/Na levels, skin pigment, salty food craving, hypotension, fatigue
adrenal overproduction/cushing’s disease causes/Sx
causes: endogenous w/ tumors, etc; or exogenous due to meds
Sx: cortisol overproduction -> moon face, buffalo hump on shoulders, high blood/glucose, excess body hair growth in women, striae on skin
T4/T3 and relation to thyroid function
t4 = inactive / t3 = active
hypothyroid = TSH high b/c low T4/T3 hyperthyroid = TSH low b/c high T4/T3
T4/T3 and relation to thyroid function
t4 = inactive / t3 = active
hypothyroid = TSH high b/c low T4/T3 hyperthyroid = TSH low b/c high T4/T3
pituitary adenoma Sx
hypersecretion of hormone
deficiency of hormone (LH/FSH)
headaches, visual disturbances, loss of balance, seizures
where does thyroid lie
isthmus over 2-4 tracheal rings
soft thyroid seen in
Grave’s
firm thyroid seen in
Hashiomoto’s and malignancy
tender thyroid seen in
thyroiditis
DM Sx/Labs
Sx: polyurea, thirst, fatigue, cuts/bruises slow to heal, feeling hungry, weight loss
labs: FG > 126 mg/dL
A1C > 6.5%
random glucose > 200 mg/dL
Metabolic Syndrome
Sx: abdominal obesity, insulin resistance, elevated BP, lipid abnormalities
prevalence increases w/ age and body weight but cause unk
geriatric meds assessment
- brown bag check: bring in bag w/ all meds
- ask prescriptions, OTC, vitamins, herbs, supplements
- review meds every visit
- use Beer’s criteria to avoid prescribing meds w/ adverse effects
- start low, go slow (dosage for elderly)
- close followup after starting new medication
assessment tools for functional ability and risk of falls
- ability to perform activities of daily living (ADL)
- -self care, housework, meal prep, taking meds, managing finances, using telephone
- useful scales: Katz, Lawton ADL scales
risks secondary to DM
retinopathy -> blindness
nephropathy -> kidney failure
neuropathy of hands/feet
vascular changes -> MI/strokes
DKA at risk in T1 or T2DM
T1
geriatric vision assessment
- Snellen eye chart
- ophthalmologist referral to monitor DM Pt
- ophthalmologist referral for Pt w/ glaucoma risk (FH)
- assess vision for driving safety
mini-mental status exam
mild = 21-29 moderate = 10-20 severe = 0-9
*not relaible if Pt cant read/write or not fluent
diabetic retinopathy Sx
black spots in visual field
geriatric hearing loss
age-related sensorineural hearing loss most common hearing condition in older Pts, loss of high frequency hearing
Sx: hearing loss w/ tinnitus/vertigo/poor balance (fall risk)
cause: CN8, review meds for ototoxicity
stress incontinence
involuntary leakage w/ sneezing, coughing, laughing, exertion, etc
urge incontinence
detrusor overactivity, leading to uninhibited detrusor contractions
