FCCN LEVEL 1 EXAM QUESTIONS WITH ACCURATE
ANSWERS
3 components of stroke volume correct answer preload = blood volume
afterload = resistance (how clamped or dilated the vessels are)
contractility = Squeeze of the heart
4 phases of AKI correct answer - onset
- oliguric
- diuretic = indicates return of tubular function
- recovery
ACE inhibitors correct answer - initial dose can drop BP dramatically
- subsequent double dosing shold not drop the BP significantly
-- BP is not a good parameter for finding effective dose for HF patient
acute kidney injury correct answer - decreased kidney function within 48 hrs
- UO < 0.5 ml/kg/hr for 6 to 12 hrs
ADH (antidiuretic hormone) correct answer - water retainer
- vasoconstrictor (also called Vasopressin)
- produced by hypothalamus
,- store and released from posterior pituitary
ADH pathway correct answer - hypothalamus senses low blood volumed and
increased serum osmolality
- signal pituitary to release ADH
- ADH causes kidney to retain water
- water retention increases blood volume and decreases serum osmolality
ANP (atrial natriuretic peptide) correct answer - cardiac hormone stored in atria
- released when atrial pressure increases
*works opposite of RAAS by decreasing BP and reducing intravascular volume
- important diagnostic marker in CHF
assessment for postrenal failure correct answer - oliguric or anuric
- fluid excess
assessment for prerenal renal failure correct answer - oliguria
- fluid deficit (hypotension, tachycardia, dry membranes, weak, change in LOC)
AV fistula correct answer - listen for bruit
, - feel for thrill
- requires 2 to 3 months to heal before using
- lasts longest
- fewest infections
- fewest clotting problems
AV graft correct answer - synthetic graft material that connects artery to vein
- 4 to 8 weeks to heal
- increased risk for clotting and infection
best time for blood transfusion to dialysis pt correct answer - during dialysis
blood correct answer - not a risk free fluid replacement
- this is liquid transplant
blood pressure pitfalls correct answer - insensitive sign of early shock
- must compare to patient baseline
- first BP should always be done manually
*just because you have a BP does not mean the body is being perfused
