Correct Answer is D

Explanation

- Choice A: The recommended hepatitis vaccine series is not a series of four. The Advisory Committee on Immunization Practices (ACIP) recommends a three-dose series for hepatitis B vaccination.
- Choice B: Hepatitis B is not typically transmitted by contaminated food. It is primarily spread through direct contact with infectious blood, semen, or other body fluids.
- Choice C: While there is some evidence suggesting a link between chronic hepatitis C infection and an increased risk of renal cell carcinoma, the statement is not universally accepted as fact and more research is needed to establish a definitive connection.
- Choice D: Individuals with a history of hepatitis B or C are generally ineligible to donate blood due to the risk of transmission of these bloodborne viruses.

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.
