Which of the following is a recommended practice while administering medication to a client?

Watching the client swallow their medication is a crucial practice during medication administration. This step ensures that the medication is actually taken and reduces the risk of medication errors, such as the client pocketing the medication or refusing to take it without proper communication. By monitoring the ingestion process, it allows for immediate feedback and confirmation that the medication has been consumed, which is essential for effective treatment.

Other practices, like documenting after medication administration, are important, but they do not directly contribute to the immediate verification of successful medication intake. Ensuring staff presence for verification can enhance safety, but it is not a routine requirement and may not be practical in every situation. Using a timer to manage preparation can improve efficiency, yet it does not directly impact the client's medication adherence or safety during the administration process. Thus, the focus on confirming that the client has swallowed the medication is the most significant best practice in ensuring proper medication administration.
