What action should the nurse take before implementing a Tylenol prescription for a client who previously overdosed on it?

Before implementing a Tylenol prescription for a client who previously overdosed on it, the nurse should question the prescription. This is crucial because a history of Tylenol overdose indicates a significant risk for hepatic toxicity if the medication is administered again. The client’s previous overdose raises serious concerns regarding their ability to metabolize acetaminophen safely, and it is essential for the nurse to ensure the safety of the patient by clarifying the necessity of the prescription with the prescribing physician.

Questioning the prescription allows the healthcare team to assess whether an alternative pain management strategy should be employed, given the patient’s medical history. This proactive step not only safeguards the patient’s health but also demonstrates the nurse's responsibility in medication management and patient safety measures.
