Explanation

Isolyte-P is a balanced pediatric maintenance solution specifically designed for children.
It contains 5% dextrose, which is crucial for preventing hypoglycemia and starvation ketosis in a fasting child who has limited glycogen stores.
The electrolyte composition of Isolyte-P is tailored to meet the daily maintenance requirements of a child, preventing imbalances.
It is an isotonic solution, making it safe for peripheral administration and preventing drastic fluid shifts.

Option B: 10% Dextrose solution lacks essential electrolytes like sodium and potassium. Administering it as a maintenance fluid can lead to dilutional hyponatremia (low sodium) and other electrolyte disturbances.
Option C: A combination of 0.9% Normal Saline with 10% Dextrose creates a hypertonic solution. Such solutions are not used for routine maintenance in children as they can cause cellular dehydration and are typically reserved for specific, complex electrolyte disorders.
Option D: Ringer lactate is an isotonic crystalloid that does not contain any dextrose (glucose). For a child who is fasting, a glucose source is essential to prevent hypoglycemia. RL is designed for volume replacement, not caloric maintenance.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pediatric Intravenous Maintenance Fluid Therapy as background academic context rather than a clinical decision trigger.
Children have higher metabolic rates and lower glycogen stores than adults, making them more susceptible to hypoglycemia during periods of fasting. Providing a dextrose-containing maintenance fluid is a critical patient safety measure.
Nurses are responsible for correctly administering IV fluids and monitoring the patient for therapeutic effects and potential complications like fluid overload, electrolyte imbalances, and hypoglycemia. Careful calculation and regulation of the infusion rate are essential.
What if? If the 6-year-old child arrived for the procedure with signs of severe dehydration (e.g., tachycardia, poor skin turgor, lethargy) from vomiting the previous night, the priority would shift. The initial fluid would be a bolus of Ringer lactate (20 mL/kg) for resuscitation, followed by a maintenance fluid like Isolyte-P once stable.

How to Approach the Question

First, identify the patient's clinical situation: a 6-year-old child who is stable but NPO for a procedure.
Determine the primary goal of fluid therapy. In this case, it is 'maintenance' – to provide daily requirements of water, electrolytes, and calories, not 'resuscitation' or 'replacement' of a large deficit.
Recall the essential components of a pediatric maintenance fluid: water, electrolytes, and a glucose source (dextrose) to prevent hypoglycemia.
Evaluate each option based on these requirements. Eliminate Ringer lactate because it lacks dextrose. Eliminate 10% Dextrose because it lacks electrolytes.
Compare the remaining options. Isolyte-P is specifically designed for pediatric maintenance. 0.9% NS with 10% Dextrose is a non-standard, hypertonic solution not used for routine maintenance.
Conclude that Isolyte-P is the only option that safely and effectively meets all the requirements for pediatric maintenance fluid therapy.
