EXAM 1 SET A
Question 1
Intracellular fluid (ICF) constitutes approximately what percentage of total body weight?
A) 20%
B) 30%
C) 40%
D) 60%
Answer: C
Rationale: Intracellular fluid is about 40% of body weight, while extracellular fluid is about 20%.
This distribution is essential to understand for fluid balance assessment.
Question 2
Extracellular fluid (ECF) constitutes approximately what percentage of total body weight?
A) 10%
B) 20%
C) 30%
D) 40%
Answer: B
,Rationale: Extracellular fluid is about 20% of body weight. ECF includes interstitial fluid, plasma,
and transcellular fluids.
Question 3
Interstitial fluid (ISF) is best described as:
A) The fluid inside cells
B) The fluid component of blood
C) Filtrate of blood located between cells or between cell and capillaries, normally lacking
protein
D) Fluid found in the digestive tract
Answer: C
Rationale: Interstitial fluid is a filtrate of blood located between cells or between cells and
capillaries. It normally lacks protein, which distinguishes it from plasma.
Question 4
Hydrostatic pressure is best described as:
A) The pulling force of solutes in the bloodstream
B) The pushing force of water that pushes water into cells
C) The pulling force of albumin
D) The pressure exerted by sodium in the blood
Answer: B
Rationale: Hydrostatic pressure is the pushing force of water, controlled by water in the
bloodstream. It pushes water into cells.
Question 5
Osmotic pressure is best described as:
A) The pushing force of water
B) The pulling force of solutes in the bloodstream
C) The pressure created by albumin
D) The pressure in the interstitial space
Answer: B
, Rationale: Osmotic pressure is the pulling force of solutes in the bloodstream. Electrolytes and
sodium in blood vessels draw fluid toward them.
Question 6
Oncotic pressure is specifically the pulling force of which substance?
A) Sodium
B) Potassium
C) Albumin
D) Glucose
Answer: C
Rationale: Oncotic pressure is the pulling force of albumin. Albumin is the biggest solvent,
exerts a lot of force, and pulls a significant amount of fluid toward itself.
Question 7
Osmoreceptors are located in which structure and what is their primary function?
A) Kidneys; they regulate urine output
B) Hypothalamus; they count solutes and trigger the thirst response
C) Heart; they detect fluid overload
D) Adrenal glands; they release aldosterone
Answer: B
Rationale: Osmoreceptors are located in the hypothalamus. They detect solute concentration
and trigger the thirst response when high particles and low fluid are present in the
bloodstream.
Question 8
Hypervolemic hyponatremia is characterized by:
A) Low sodium and low fluid volume
B) Excess water that dilutes sodium
C) High sodium and high fluid volume
D) Low potassium and high sodium
Answer: B
