Topic 1: Fundamentals of Fluid and Electrolyte Physiology
and Homeostasis Questions 1-20




Question 1:

A nurse is assessing a patient with suspected dehydration. Which
clinical finding most strongly indicates fluid volume deficit?

A) Peripheral edema
B) Dry mucous membranes and decreased skin turgor
C) Jugular vein distention
D) Hypertension

Correct Answer:
B) Dry mucous membranes and decreased skin turgor

Rationale:
Dry mucous membranes and decreased skin turgor are classic
signs of dehydration and fluid volume deficit. Edema and jugular
vein distention indicate fluid overload, while hypertension is more
typical of hypervolemia.




Question 2:

Which hormone primarily regulates sodium and water retention in
the kidneys?

, 4


A) Thyroxine
B) Aldosterone
C) Cortisol
D) Parathyroid hormone

Correct Answer:
B) Aldosterone

Rationale:
Aldosterone promotes sodium and water retention while excreting
potassium, maintaining fluid balance. Parathyroid hormone
regulates calcium, cortisol affects metabolism, and thyroxine
regulates metabolic rate.




Question 3:

The nurse knows that which fluid compartment contains the
largest percentage of total body water?

A) Intravascular
B) Interstitial
C) Intracellular
D) Transcellular

Correct Answer:
C) Intracellular

Rationale:
Approximately two-thirds of total body water is found within cells
(intracellular compartment), making it the largest fluid
compartment in the body.
