NURS 352 Exam Questions and
Answers 100% PASS
What is third spacing - CORRECT ANSWER-loss of ECF into space from the
body but not available to be used by the ECF or or ICF
What are some spaces where third spacing can happen - CORRECT ANSWER-
Peritoneal cavity and pleural cavity
What are some signs that third spacing is happening - CORRECT ANSWER-there
is a decrease in urine output even when having proper intake
What is osmosis - CORRECT ANSWER-diffusion of water caused by fluid and
solute concentration gradients that move from high to low concentration
What is starlings laws of capillary forces - CORRECT ANSWER-the two forces at
every capillary membrane: hydrostatic and osmotic pressure
What is hydrostatic pressure; how does it work - CORRECT ANSWER-Pressure
exerted by fluid on the walls of blood vessel
pushes fluid out of the capillary toward the ICF
What is osmotic pressure; how does it work - CORRECT ANSWER-pressure
exerted by the solutes within the plasma
,pulls the fluid into the capillary from the ICF
What is colloid oncotic - CORRECT ANSWER-osmotic pressure specifically
exerted by albumin in the bloodstream
What is tonicity - CORRECT ANSWER-the ability of solutes to cause osmotic
driving force that promotes water movement
Isotonic solutions - CORRECT ANSWER-Same sodium and chloride
concentration as the bloodstream and the same water concentration as the
bloodstream
does not provoke change between ICF and ECF compartments
Isotonic solutions expand the plasma volume of blood
Hypotonic solutions - CORRECT ANSWER-composed of less sodium chloride
concentration than blood
0.45 %NaCl and 0.25 % NaCl

,less solute but more water than bloodstream
Move water from ECF to ICF
used to hydrate patient
Hypertonic Solution - CORRECT ANSWER-Composed of a greater
concentration of NaCl compared to blood
3% NaCl
More solute concentration and less water
Pulls water from the ICF to the ECF
Helps with edema, and cerebral edema
What is manitol used for and what classification is it - CORRECT ANSWER-It is
a hypertonic solution
moves water from ICF to ECF rapidly
, What is osmotic diuresis - CORRECT ANSWER-increase in urine output caused
by the excretion of solutes
Factors that increase serum osmolality - CORRECT ANSWER-severe dehydration
free water loss
D.I
hypernatremia
hypergylcemia
Acute tubular necrosis
Factors that decrease serum osmolality - CORRECT ANSWER-Fluid volume
excess
SIADH
Acute kidney injury
adrenal insufficiency
hyponatremia
overhydration
diuretic use
