The practical nurse (PN) is administering a saline enema to a client who was admitted because of a fever of unknown origin and is now constipated. Which techniques should the PN use? (Select all that apply.)

A. Inserting the lubricated tip of the tubing 3 to 4 inches into the rectum allows for the proper administration of the enema. B. Positioning the client in the left lateral recumbent position helps expose the rectum for the enema administration. C. Chilling the enema solution isn't recommended as it might cause discomfort or shock to the client. D. Encouraging the client to retain the solution for at least 5 minutes helps ensure effectiveness. E. Clamping the enema administration tubing after filling the enema bag helps control the flow during the procedure.
