Correct Answer: A

Rationale: In this situation, the nurse should attempt to distract the client with general conversation. Distracting the client can help reduce anxiety and make the procedure less stressful. Administering pain medication (choice B) is not appropriate as the client's discomfort is related to anxiety, not physical pain. Continuing with the procedure while reassuring the client (choice C) may not address the client's anxiety effectively. Stopping the procedure and notifying the healthcare provider (choice D) is not necessary at this point since the client's anxiety can be managed by attempting to distract him.

Correct Answer: D

Rationale: The corrected question assesses the client's understanding of lifestyle modifications for peptic ulcer disease. Choice D, 'I should avoid drinking alcohol to prevent irritation of my ulcer,' is the correct answer. This statement demonstrates that the client has a good grasp of the teaching provided, as alcohol can indeed irritate peptic ulcers. Choices A, B, and C are all accurate statements that reflect appropriate understanding of managing peptic ulcer disease and do not indicate a need for further teaching.

Correct Answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.

Correct Answer: C

Rationale: There are several antianxiety medications that are not contraindicated for breastfeeding mothers, so it is important to inform her of this option.

Correct Answer: B

Rationale: Corrected Rationale: In a client with chronic heart failure, serum potassium levels should be closely monitored to assess for hyperkalemia, which can worsen heart failure. Monitoring serum sodium levels is not the priority in this case. Serum creatinine level monitoring is more related to kidney function than heart failure. Hemoglobin levels are important but not the primary concern when assessing heart failure exacerbation.
