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.

Correct Answer is C
Explanation
Rationale:
A. Seizures are more commonly associated with severe electrolyte imbalances like hyponatremia, not mild hypokalemia.
B. Neurogenic shock is related to spinal cord injury, not potassium imbalance.
C. Hypokalemia (potassium 3.3 mEq/L; normal 3.5–5.0 mEq/L) increases the risk of ventricular arrhythmias, palpitations, and potentially life-threatening cardiac complications, especially in clients taking diuretics like furosemide.
D. Low potassium does not directly cause hypoglycemia.
Correct Answer is ["D","E","F"]
Explanation
Rationale:
- Improved breathing indicates that the removal of ascitic fluid has relieved diaphragmatic pressure, allowing better lung expansion.
- Decreased abdominal pressure demonstrates that fluid removal has reduced intra-abdominal tension, improving mobility and comfort.
- Relief of abdominal discomfort is a primary goal of paracentesis, as it enhances quality of life and reduces pain caused by fluid accumulation.
- Stable vital signs and absence of respiratory distress are important for monitoring safety but are not direct measures of the procedure’s effectiveness.
- Reduced ascitic fluid volume is the mechanism of action of paracentesis, while the client’s symptomatic relief is the best indicator of clinical success.
