A nurse is preparing a cleansing enema for a 15-year-old. What volume of solution is appropriate?

• A. 150 to 250 mL
• B. 500 to 750 mL
• C. 250 to 350 mL
• D. 300 to 500 mL

Answer: (B)

Volume for a cleansing enema is chosen based on the patient’s size and tolerance. In older children and adolescents, the colon is closer to adult size, so volumes nearer adult regimens are appropriate. For a fifteen-year-old, about half a liter to three-quarters of a liter of solution provides enough fluid to help evacuate stool while minimizing cramping and the risk of distension or fluid and electrolyte shifts that come with very large volumes. This range offers a practical balance between effectiveness and safety for a teen. Smaller volumes are generally used in younger children and may not be sufficient for cleansing a teen, while much larger volumes can be excessive for many adolescents. If tolerated well, approaching the higher end within this range is reasonable, with adjustments made for comfort and clinical goals.
