What must be documented after a medication is administered?

When documenting after a medication is administered, it is essential to include the time, dosage, and any reactions. This practice is vital for several reasons. Firstly, it ensures that a complete record of the patient's medication administration is maintained, which is critical for safety and accountability. The time of administration is necessary for tracking medication schedules, while the dosage confirms that the exact amount prescribed was given. Additionally, documenting any reactions helps to monitor the effectiveness of the medication and to identify any potential side effects or adverse reactions, ensuring prompt intervention if necessary. This thorough documentation supports continuity of care and is crucial for effective communication among healthcare providers involved in the patient's care.
