Correct Answer is D

Explanation

- 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.

A. Blood pressure 156/90 mm Hg B. Pulse 54/min C. Potassium 5.2 mEq/L D. Sodium 130 mEq/L

Correct Answer is B

Explanation

A. While a blood pressure of 156/90 mm Hg may be elevated, it is not necessarily an indication to withhold propranolol, which is commonly used to treat hypertension.

B. A pulse rate of 54/min suggests bradycardia, which is a potential side effect of propranolol and may warrant withholding the medication.

C. A potassium level of 5.2 mEq/L is within the normal range (3.5-5.0 mEq/L) and is not typically a reason to withhold propranolol.

D. A sodium level of 130 mEq/L is within the normal range (135-145 mEq/L) and is not typically a reason to withhold propranolol.
