A 6 years old baby is kept NPO before 4 hours of endoscopy procedure. Which of the following fluid would be prescribed for the baby?

Appeared in: NORCET 3 - 2022 (Shift-2)

Explanation

Isolyte-P is a balanced, isotonic intravenous solution specifically designed for pediatric maintenance.
It contains 5% dextrose, which helps prevent hypoglycemia and starvation ketosis in a child who is NPO (nothing by mouth).
Its electrolyte composition (e.g., ~40 mEq/L of sodium) is tailored to meet a child's daily requirements without the risk of overload associated with adult fluids.

Option B: 10% glucose is a hypertonic solution that lacks electrolytes (sodium, potassium, chloride).
Option C: This option is redundant and nonsensical, as DNS already contains 0.9% NS. It represents DNS, which has a sodium concentration of 154 mEq/L, far too high for routine pediatric maintenance.
Option D: DNS (Dextrose 5% in 0.9% Normal Saline) contains a high sodium load (154 mEq/L), which can lead to hypernatremia and hyperchloremic metabolic acidosis in children.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pediatric Intravenous Fluid Management as background academic context rather than a clinical decision trigger.
Choosing the correct IV fluid is critical in pediatrics due to their smaller body size, different metabolic rate, and narrower margin for error.
Incorrect fluid choice can lead to serious complications like hypernatremia (from high-sodium fluids), hyponatremia (from hypotonic fluids without adequate monitoring), and fluid overload.
Nurses are responsible for administering the prescribed fluid and monitoring the child for signs of fluid imbalance, electrolyte abnormalities, or adverse reactions.

How to Approach the Question

First, identify the key patient characteristics: a 6-year-old child.
Next, understand the clinical context: the child is NPO for a procedure. This means they need 'maintenance' fluids, not 'replacement' or 'resuscitation' fluids.
Evaluate the options based on suitability for pediatric maintenance. Look for a fluid that provides water, a small amount of glucose, and balanced electrolytes.
Recognize that fluids like DNS (0.9% NS) have high sodium content, making them less ideal for routine pediatric maintenance.
Identify 'Isolyte-P' where 'P' strongly suggests 'Pediatric', making it the most likely purpose-designed and safest option.
