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?

Choice A reason:

This statement is correct. Family history and genetic factors are considered significant risk factors for peptic ulcer disease. A positive family history increases the likelihood of developing the condition.

Choice B reason:

Excessive consumption of fresh fruits and vegetables is not a risk factor for peptic ulcer disease. In fact, a diet rich in fruits and vegetables is generally associated with a lower risk of developing peptic ulcers.

Choice C reason:

Regular exercise and maintaining a healthy weight are not considered risk factors for peptic ulcer disease. These factors are essential for overall health but are not directly related to ulcer development.

Choice D reason:

While stress and emotional factors may exacerbate peptic ulcer symptoms, they are not the primary cause of the condition. The primary causes are Helicobacter pylori infection and the use of nonsteroidal anti-inflammatory drugs (NSAIDs).

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.
