When is an enema typically administered?

An enema is typically administered to alleviate constipation. The procedure involves introducing liquid into the rectum to stimulate bowel movements, soften stool, and help relieve discomfort associated with constipation. This method is particularly effective when oral laxatives are insufficient or in situations where rapid evacuation of the bowels is necessary, such as before certain medical examinations or surgeries.

Other options, while related to various medical conditions, do not correctly represent the primary purpose of administering an enema. For hydration, appropriate methods would include intravenous fluids or oral rehydration solutions. Testing blood sugar typically requires blood samples taken from the finger or arm, rather than using an enema. Providing nutrients is usually accomplished through nutritional feeds, enteral feeding tubes, or intravenous nutrition, as enemas do not effectively deliver nutrients systemically.
