AH II Exam I Flashcards
What does the acronym SPICES stand for?
Sleep disorders Problems with eating and feeding Incontinence Evidence of falls Skin breakdown
What 2 assessments do we use to observe changes from the baseline in older adults?
ACES Assess function and expectations for ADLs Coordinate and manage care use Evolving knowledge makeSituational decisions
-used to Advance Care for the Excellence of Seniors
SPICES
assesses changes to their normal ADLs
What happens to each body system as we age?
kidney function, thirst and fluid status all decrease
If an older adult is having problems with swallowing/chewing, what do we want to give them?
THICKENED liquids
for example: a shake instead of a lemonade to reduce the risk of aspiration
What is a high risk BRADEN scale? What does it mean? How should a nurse intervene?
a low Braden score indicates a high risk for pressure ulcers
the highest risk score you can get is 6
no risk for ulcers is 23
Nursing Action: turn the patient every 2 hours. It only takes 20 minutes for an ulcer to begin developing.
What is a high risk MORSE scale? What does it mean? How should the nurse intervene?
a score over 50 indicates a high risk for falls
Nursing Action: get rid of environmental hazards, assess for muscle weakness.
When assessing an older adult’s AAOX3, are they oriented if they are off by just one day?
NO- the nurse should be reorienting the patient daily.
What is the “triple S” associated with chronic illness?
Sedentary lifestyle
Smoking
Stress
What defines a chronic illness?
it is permanent, and caused by a non-reversible pathological alteration.
it has a remission-exacerbation cycle.
What is the difference between the NIC and the NOC?
NIC- provides standardized patient interventions
NOC- provides standardized patient outcomes
What are 3 isotonic fluids? When are they indicated? When are they contraindicated?
0.9% Normal Saline
D 5% W
Lactated Ringers
Indicated: to increase intravascular volume
can be used in conjunction with blood products
Contraindicated: volume overload
do NOT gives lactated ringers when patient is alkylotic or in liver failure
What are 3 HYPOtonic fluids? When are they indicated? When are they contraindicated?
0.45% (half) normal saline
33% (one third) normal saline
2.5% (half) dextrose
Indicated: to draw water into the cell
Contraindicated: anasarca, cerebral edema, HYPOtension
What are 3 HYPERtonic fluids? When are they indicated? When are they contraindicated?
D 5% W in 0.45% NS
D 5% W in 0.9% NS
D 5% W in lactated ringers
Indicated: to draw water into the vessels
Contraindicated: heart failure, DKA
What is the pressure called that PULLS (absorbs) fluid from the interstitial space?
colloid oncotic pressure
What are the 4 routes too edema?
- increased capillary permeability r/t burns, allergies, inflammatory reactions, etc.
- decreased capillary oncotic pressure r/t loss of plasma proteins
- increased capillary hydrostatic pressure r/t vein obstruction, salt/water retention and heart failure
What are the 4 routes too edema?
- increased capillary permeability
- decreased capillary oncotic pressure
- increased capillary hydrostatic pressure
- lymphatic obstruction
How do decreased blood volume and decreased blood pressure affect osmolarity?
They both lead to a decrease in osmolarity.
They tell the atria and great veins that they need more fluid.
That sets off an increase in ADH.
ADH increase causes reabsorption of water into the vessels which decreases the concentration of electrolytes there (decreases osmolarity)
What are the three things that cause the body to increase its ADH production and consequently decrease its osmolarity? (yes. do the big list)
- decreased blood volume/blood pressure
- too high an increase in osmolarity (sensed by the hypothalamus)
- extrinsic factors such as:
HAANNSS
Heat
Anesthetics
Antineoplastics (chemo)
Narcotics
Nicotine
Surgery
Stress
Describe the RAAS cycle.
- Triggered by low BP
- Kidneys release renin which travels to the liver
- Renin converts angiotensin to angiotensin I
- Angiotensin I travels to the lungs to be converted by ACE into angiotensin II
- Angiotensin II powerfully vasoconstricts vessels and increases BP
What is the best indicator of fluid status?
daily weight
What are the 2 most important things to monitor during rehydration?
HR
urine output
Dilution of which two electrolytes can lead to seizures, coma and death?
sodium and potassium
Urine output below _____ for a kidney patient is cause for concern?
500mL/day
or
1lb/day
What is the most common type of fluid loss problem?
isotonic dehydration
A patient with acute kidney injury or chronic kidney disease is at risk for fluid volume _____
excess
What are the 5 clinical signs of HYPOvolemia?
sudden weight loss flat neck veins HYPOtension tachycardia weak, thready pulse
What are the 4 clinical LABS for HYPOvolemia?
Increased hematocrit
Increased BUN (>25)
Increased urine specific gravity (> 1.03)
Increased serum sodium
What are the 3 clinical signs of HYPERvolemia?
sudden weight gain
distended neck veins
lung crackles
What are the 4 clinical LABS for HYPERvolemia?
Decreased hematocrit
Decreased BUN (< 10)
Decreased urine specific gravity
Decreased serum sodium
What are 3 nursing management options for HYPOvolemia?
check urine output
monitor for bounding pulse/difficulty breathing when rehydrating
give ~100mL/hr PO fluid replacement
What are 4 nursing management options for HYPERvolemia?
prevent skin breakdown from edema/oxygen therapy
administer diuretics
restrict fluid
restrict sodium to 2-4g/day
Sodium Range:
135-145
HYPOnatremia neuromuscular:
decreased mm contraction that leads to shallow respirations
How does the nurse fix HYPOnatremia?
if related to excess fluid intake, restrict fluids and administer diuretics
if related to decreased sodium intake, replace with hypertonic solution like 3-5% normal saline
Common causes of HYPOnatremia:
excessive sweating wound drainage diuretics HYPOtonic fluids HYPERglycemia
Potassium LOSS can be caused by an INCREASE in what hormone?
aldosterone
