MULTIPLE CHOICE
1.A patient has dehydration. While planning care, the nurse considers that the majority of the patient’s total
water volume exists in with compartment?
a. Intracellular
b. Extracellular
c. Intravascular
d. Transcellular
ANS: A
Intracellular (inside the cells) Ԩuid accounts for approximately two thirds of total body water. Extracellular
(outside the cells) is approximately one third of the total body water. Intravascular Ԩuid (liquid portion of the
blood) and transcellular Ԩuid are two major divisions of the extracellular compartment.

2.The nurse is teaching about the process of passively moving water from an area of lower particle
concentration to an area of higher particle concentration. Which process is the nurse describing?
a. Osmosis
b. Filtration
c. DiԨusion
d. Active transport
ANS: A
The process of moving water from an area of low particle concentration to an area of higher particle
concentration is known as osmosis. Filtration is mediated by Ԩuid pressure from an area of higher pressure to
an area of lower pressure. DiԨusion is passive movement of electrolytes or other particles down the
concentration gradient (from areas of higher concentration to areas of lower concentration). Active transport
requires energy in the form of adenosine triphosphate (ATP) to move electrolytes across cell membranes
against the concentration gradient (from areas of lower concentration to areas of higher concentration).

3.The nurse observes edema in a patient who has venous congestion from right heart failure. Which type of
pressure facilitated the formation of the patient’s edema?
