What information is necessary to document after medication administration?

The correct choice emphasizes the essential components that must be documented after administering medication. This includes the medication name, the exact dose that was given, the precise time of administration, as well as any patient responses or side effects observed after administration. Thorough documentation is crucial for ensuring patient safety and continuity of care, as it provides a clear record for other healthcare providers.

Including the medication name and dose helps to prevent errors and ensures that there is a reliable account of what was administered. Documenting the time of administration is vital because it allows for tracking the medication's effects and for scheduling future doses. Noting any patient responses or side effects is also important, as this information can guide further treatment and alert healthcare providers to potential adverse reactions.

In contrast, the other options do not include the necessary details for proper medication administration documentation. Only capturing how a patient felt or just the time of administration omits critical information that could affect treatment plans. Additionally, documenting financial details like medication costs or insurance information does not pertain to the effects of the medication itself and does not contribute to the safe practice of medication administration.
