T/F When infusing isotonic IV solution older adults are at risk for fluid
overload. Correct Answer-True
Hypertonic solutions move fluid from the _____ into the ________.
a. bloodstream; cells
b. tissues; muscles
c. cells; bloodstream
,d. muscles; tissues Correct Answer-c. cells; bloodstream
Hypertonic solutions greatly expand what space?
a. tissue
b. interstitial

a. shifts fluid out of the blood vessels
b. reduces the risk of edema
c. causes unstable BP
d. regulates urine output Correct Answer-b, d
T/F Diffusion occurs when a hypertonic solution is administered.
Correct Answer-False; Osmosis occurs when a hypertonic solution is
administered
List the 4 conditions in which you would not give a hypertonic solution
(C, D, D, D) Correct Answer-CHF, DKA, Decreased Renal Function,
Dehydration
, Does infusing an isotonic solution alter the concentration of serum?
Why? Correct Answer-No, because it is the same osmolarity as serum
and therefore there is no movement of fluid across the membrane.
Does osmosis occur with an isotonic solution? Why? Correct Answer-
No, because it is the same osmolarity as serum and therefore there is no
movement of fluid across the membrane.
Name one isotonic solution that osmosis can occur. Why? Correct
Answer-D5W, because it is only isotonic in the bottle. Shortly after it is
administered the sugar is metabolized and the solution becomes
hypotonic.
A difference in the concentration between the serum and interstitial fluid
will cause ______ to occur. Correct Answer-Osmosis
Which isotonic solution would you not give if a patient has liver
disease?
a. 0.9% normal saline
b. Lactated ringers
c. D5W
d. D5 .45 Correct Answer-b. Lactated ringers
Which isotonic solution would you not want to give to someone with
increased ICP?
