What should a nurse instruct a family about when administering a tap water enema to an older adult?

When administering a tap water enema to an older adult, it is important to instruct the client to bear down during the rectal tube insertion. This action can help relax the anal sphincter and facilitate the comfortable and safe insertion of the rectal tube. Encouraging the client to bear down mimics the natural process of a bowel movement, which can ease the insertion and make the procedure less uncomfortable for the patient.

In older adults, anatomical and physiological changes can lead to increased sensitivity or discomfort during such procedures, making this instruction crucial for effective administration. It is important to maintain the comfort of the patient while ensuring that the enema is delivered properly to promote the desired bowel movement.
