Which of the following is NOT one of the Five Rights of medication administration?

The Five Rights of medication administration are essential principles that ensure safe and effective medication delivery to patients. These principles are: the Right Patient, the Right Medication, the Right Dose, the Right Route, and the Right Time.

In the context of this question, "Manufacturer" does not fit within these foundational principles. While knowing the manufacturer might be relevant in some scenarios, such as when considering differences in formulations or potential recalls, it does not directly contribute to the safe administration of medication in the context of patient care. The emphasis is rather on ensuring that the patient receives the correct medication in the appropriate dose and method at the proper time.

Understanding the Five Rights helps practitioners minimize the risk of medication errors and ensures a systematic approach to patient safety in medication administration.
