What is the recommended respiration phase when inserting an enema tip?

1. Inspiration

2. Expiration

3. Mid-inspiration

4. Any phase

The correct answer is: Expiration

Inserting an enema tip is performed during the expiration phase of respiration. During this phase, the diaphragm ascends, which reduces the volume of the thoracic cavity and increases abdominal pressure. This state of abdominal compression provides a more stable environment for the insertion of the enema tip, allowing for smoother and more controlled placement. If the procedure were to be performed during inspiration, the diaphragm would be descending, potentially creating additional abdominal tension and discomfort for the patient. This could lead to difficulty in the procedure, as the full descending movement does not allow for optimal access to the rectum. In contrast, performing the insertion during mid-inspiration would be less effective than during full expiration, as abdominal pressures would still be fluctuating. The ideal phase, which is expiration, minimizes discomfort and promotes patient cooperation during the procedure. Hence, selecting expiration as the recommended phase aligns with standard practices to ensure a safer and more effective insertion process.
