A nurse is preparing to administer vancomycin to a client who has an infected wound. The nurse should plan to monitor for which of the following adverse reactions?

- A: Diabetes mellitus is not listed as a contraindication for methylergonovine.
- B: Hypertension is a contraindication for methylergonovine because it can cause severe hypertension and other cardiovascular effects.
- C: Migraine headaches are not listed as a contraindication for methylergonovine.
- D: Hepatitis B is not listed as a contraindication for methylergonovine.

- A) Utility: This principle is about producing the greatest good for the greatest number. In the case of a medication error, the focus is not on the collective good but on the individual patient's rights and well-being.
- B) Paternalism: This principle involves making decisions for others, potentially against their will, for their own good. It does not directly apply to the situation of a medication error where the patient's autonomy and right to be informed are paramount.
- C) Fidelity: This principle refers to loyalty and keeping one's promises. While important, it is secondary to the immediate need for honesty and transparency in the event of a medication error.
- D) Veracity: This principle obligates healthcare providers to tell the truth. When a medication error occurs, it is crucial to inform the patient about the mistake and the steps being taken to remedy it, making veracity the most applicable ethical principle in this scenario.
