A nurse is caring for a client with a peptic ulcer who is prescribed histamine-2 (H2) receptor blockers. Which of the following laboratory values should the nurse monitor closely while the client is taking H2 receptor blockers?

Serum potassium levels

Blood glucose levels

Serum creatinine levels

Complete blood count (CBC)

Answer and Explanation

The Correct Answer is A

Choice A reason:

This statement is correct. H2 receptor blockers can sometimes cause an increase in serum potassium levels. The nurse should monitor the client's potassium levels closely to detect any abnormalities.

Choice B reason:

H2 receptor blockers do not typically affect blood glucose levels, so monitoring blood glucose is not the priority in this scenario.

Choice C reason:

H2 receptor blockers are not known to have a significant impact on serum creatinine levels, so monitoring creatinine is not the priority in this case.

Choice D reason:

H2 receptor blockers are not known to affect the CBC, so monitoring the complete blood count is not the priority for this client.

Correct Answer is A

Explanation

Choice A reason:

This question is relevant to assess for gastrointestinal symptoms, as changes in bowel movements may indicate issues with digestion or absorption.

Choice B reason:

Family history of heart disease is not directly related to peptic ulcer disease. However, it is essential for overall health assessment and risk factor identification.

Choice C reason:

Swelling or edema in the legs may be indicative of cardiovascular or circulatory issues, but it is not directly related to peptic ulcer disease.

Choice D reason:

The frequency of consuming high-fiber foods is not specifically related to peptic ulcer disease. However, diet history is essential for overall health assessment.

A. "The CT scan uses a magnetic field, so there is no radiation exposure." B. "The amount of radiation used in a CT scan is very low and safe." C. "There is no need to worry about radiation as the scan is done quickly." D. "CT scans do not use radiation; they use sound waves for imaging."

Correct Answer is B

Explanation

Choice A reason:

CT scans use X-rays, not magnetic fields, to create detailed cross-sectional images of the body. They involve radiation exposure.

Choice B reason:

This statement is correct. While CT scans use X-rays, the amount of radiation used in modern CT machines is relatively low and considered safe. The benefits of the diagnostic information obtained from the scan usually outweigh the risks associated with the small amount of radiation exposure.

Choice C reason:

The speed of the scan does not impact the radiation exposure. The amount of radiation used in a CT scan remains the same regardless of the scan duration.

Choice D reason:

CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.
