The Volume of Enema used in infants?

Appeared in: NIMHANS Nursing Officer - 2019

Explanation

The correct volume of enema solution for an infant is 100-150 mL.
Infants have a small colon capacity and immature kidneys, making them highly vulnerable to fluid overload and electrolyte imbalances.
Using a small, controlled volume prevents excessive bowel distention, potential injury, and systemic complications like water intoxication.
This volume is sufficient to stimulate peristalsis and cleanse the lower bowel without overwhelming the infant's system.

Option B: This volume is too large for an infant and risks causing significant abdominal cramping, bowel distention, and fluid overload.
Option C: This volume is appropriate for a school-aged child, not an infant. Administering this much fluid to an infant would be dangerous.
Option D: This volume is intended for adolescents and adults. It would cause severe complications, including potential bowel perforation, in an infant.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pediatric Enema Administration as background academic context rather than a clinical decision trigger.
Administering the correct enema volume is a critical patient safety measure in pediatrics to prevent iatrogenic complications.
Nurses must use isotonic normal saline for pediatric enemas, as tap water (hypotonic) is contraindicated due to the high risk of water intoxication and circulatory overload.
Hypertonic solutions (like Fleet enemas) are also generally contraindicated in infants due to the risk of causing dehydration and electrolyte shifts.

How to Approach the Question

First, identify the specific patient population mentioned in the question, which is 'infants'.
Recall the fundamental principle of pediatric nursing: children are not small adults. Their anatomical and physiological characteristics require significant adjustments in procedures and dosages.
Apply this principle to enema administration. An infant's colon is much smaller than an adult's, and their ability to regulate fluid and electrolytes is immature.
Evaluate the given options, starting from the smallest volume. Eliminate the larger volumes that are clearly intended for older children or adults.
Select the volume range that is safest and most appropriate for the infant's size and physiological limitations.
