Final answer:
Medications should be documented at the time of administration to avoid errors and ensure patient safety.
Step-by-step explanation:
When medications are administered, they should be documented at the time of administration to avoid the possibility of double dosing and to ensure accurate and timely record-keeping. Documenting medications at the end of a shift or after every meal may lead to errors or omissions in the documentation process. It is important to document medication administration promptly and accurately to maintain patient safety and provide a reliable record of the medication history.
