What instruction should a nurse give to an older adult about administering a tap water enema?

The most appropriate instruction for an older adult about administering a tap water enema is to encourage the client to relax completely. This is important because relaxation can facilitate the process of administering the enema and help prevent discomfort or injury.

When performing an enema, the individual needs to be in a comfortable position, usually lying on their side, which can help ease the passage of the rectal tube and the flow of water. If the client is tense, it can lead to increased resistance or discomfort, making the procedure more challenging and potentially less effective.

Choosing options that suggest rapid administration, standing during the procedure, or bearing down during tube insertion may not be safe or effective approaches. Quick administration can increase the risk of discomfort or cramping, standing might not provide the necessary stability and comfort for the procedure, and bearing down during insertion can lead to increased tension rather than relaxation, potentially complicating the process.
