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 glucose level of 120 mg/dL B. Serum sodium 138 mEq/L C. Oral temperature of 37.6°C (99.7°F) D. Weight increase of 2 kg (4.4 lb) in the past 24 hr

Correct Answer is D

Explanation

A. A blood glucose level of 120 mg/dL is within the expected range for a client receiving total parenteral nutrition and does not require immediate intervention.

B. A serum sodium level of 138 mEq/L is within the normal range and does not require immediate intervention.

C. An oral temperature of 37.6°C (99.7°F) is slightly elevated but may be within the client's normal range and does not require immediate intervention unless accompanied by other signs of infection.

D. A weight increase of 2 kg (4.4 lb) in the past 24 hours indicates fluid overload, which can lead to complications such as heart failure or pulmonary edema. Immediate intervention, such as adjusting the rate of fluid administration or notifying the healthcare provider, is necessary to prevent further complications.
