What is a critical action after administering a new medication?

Monitoring for any immediate reactions and documenting findings is essential after administering a new medication. This step is critical because it ensures that any adverse effects or allergic reactions can be identified promptly. Observing the patient allows the healthcare provider to assess how the patient is responding to the medication and to take necessary actions if any negative effects occur. Documentation is also important as it creates a record of the patient's response, which can be useful for future reference and for the entire healthcare team.

While it is important for patients to report any feelings or side effects, as indicated in another option, the immediate responsibility after administering a new medication lies in active monitoring. Discontinuing other medications or changing a medication based on side effects without proper procedure could lead to further complications or a lack of continuity in care, emphasizing why monitoring and documentation is the priority in this context.
