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

Answer and Explanation

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 B

Explanation

Rationale:
A. High fat content does not directly cause refeeding syndrome; fat is less likely to trigger the electrolyte shifts seen in this condition.

B. Rapid reintroduction of carbohydrates in malnourished patients stimulates insulin release, which drives phosphate, potassium, and magnesium into cells, leading to potentially life-threatening electrolyte imbalances—the hallmark of refeeding syndrome.

C. Excess protein intake can strain kidney function but is not the primary cause of refeeding syndrome.

D. Vitamin deficiencies, such as thiamine, can worsen complications, but the immediate trigger is the rapid carbohydrate load.

A. Seizures B. Neurogenic shock C. Cardiac dysrhythmias D. Hypoglycemia

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.
