What is the most appropriate action for a nurse who questions the dosage of a prescribed medication?

When a nurse has concerns about the dosage of a prescribed medication, the most appropriate action is to refuse to administer the medication. This approach emphasizes the nurse's responsibility to ensure patient safety and medication accuracy. Nurses have a duty to advocate for their patients, and administering a medication that they believe may be incorrectly dosed could lead to potentially serious consequences, including adverse effects or therapeutic failures.

By choosing not to administer the medication, the nurse can take the necessary steps to verify the dosage and collaborate with the prescribing physician to clarify any discrepancies. This action helps to prevent harm and ensures that the patient receives care that is both safe and effective. Consulting with a pharmacist is also a prudent step, but it comes after the decision to withhold the medication until the correct information is obtained.

In situations where the medication dosage raises questions, it is essential to prioritize patient safety above all else, reinforcing the importance of diligence in medication administration.
