FCCN EXAM 2025 QUESTIONS AND
ANSWERS
Intracellular - ANS fluid found inside the cells
extracelluar - ANS fluid found outside the cells
osmosis - ANS fluid moving passively across semipermeable membrane from areas with
more fluid to areas with less fluid
diffusion - ANS solutes move through semipermeable membrane from area of higher
concentration to an area of lower concentration
What should MAP be greater than? - ANS 60
another name for ADH - ANS vasopressin
normal BUN level - ANS 7-20
examples of isotonic - ANS NS, LR
what is hypotonic - ANS cell swells. more fluid in cell; diluted electrolytes
examples of hypotonic - ANS 0.45 NS, D5W

, what is hypertonic - ANS cells shrink. fluid pulled out of the cells
examples of hypertonic - ANS D5 .45/.9 NS; 3/7/23.4 NS
example of a colloid - ANS albumin
When are colloids used? - ANS when blood volume doesn't increase with IV fluids
what do colloids do? - ANS pull fluid into the bloodstream (good for 3rd spacing)
when would you use isotonic fluids? - ANS hypovolemia, blood transfusion, post surg
When would you use hypotonic fluids? - ANS GI fluid loss, hypernatremia
normal Na levels - ANS 135-145
s/s hyponatremia - ANS weakness, ab cramping, postural dizziness, decreased skin turgor,
flat neck veins
treatment? - ANS fluid restriction; potentially give fluids with sodium
s/s hypernatremia - ANS Dry mouth, Thirst, Swollen tongue (severe dehydration)
treatment? - ANS fluids fluids fluids
normal K levels - ANS 3.5-5.0
