A nurse is reinforcing discharge teaching with an older adult client's family about safety precautions when administering a tap water enema to the client. Which of the following should the nurse include in the instructions?

When administering a tap water enema, the client should be assisted to a right Sims position. This position involves lying on the left side with the right knee bent toward the chest. The other options are not correct because: a) The client should not bear down during rectal tube insertion. b) Administering a second enema if results are not clear is not mentioned as a safety precaution. d) The rectal tube should be inserted in the direction of the sacrum, not the umbilicus.
