Final answer:
d. Places the suppository a finger length into the rectum. The nurse needs to provide further teaching about suppository administration when the suppository is placed too far into the rectum.
Step-by-step explanation:
The correct answer is d. Places the suppository a finger length into the rectum. When administering a rectal suppository, it is important to insert it only about 1 inch into the rectum for it to be effective. Inserting it further can cause discomfort and potential injury. The other behaviors listed: a. lubricating the tip of the suppository, b. wearing a glove, and c. having the client bear down are all correct and appropriate steps in the administration of a rectal suppository.
