What is the primary reason for administering isotonic crystalloid IV fluids to a client with fluid volume deficit?
To replace lost blood components
To restore extracellular fluid volume
To replenish electrolytes rapidly
To correct metabolic acidosis
The Correct Answer is B
Rationale:
A. Replacing lost blood components requires blood products, not isotonic crystalloids.
B. Isotonic crystalloid fluids (e.g., 0.9% sodium chloride, lactated Ringer’s) are administered to restore extracellular fluid volume in clients with fluid volume deficit.
C. While isotonic solutions contain electrolytes, their primary purpose is volume replacement, not rapid electrolyte correction.
D. Correcting metabolic acidosis may require specific interventions; isotonic fluids alone do not address acid-base imbalances.

Explanation
Rationale
- Advise strict bed rest → Contraindicated
Strict bed rest is not necessary unless the patient is severely compromised; mobility is encouraged to prevent complications.
- Encourage high-sodium diet → Contraindicated
A low-sodium diet is essential to reduce fluid retention and ascites; high sodium worsens edema.
- Administer diuretics as prescribed → Anticipated
Diuretics (e.g., spironolactone, furosemide) help reduce ascites and edema.
- Monitor abdominal girth daily → Anticipated
Helps track fluid accumulation and assess effectiveness of interventions.
