Correct Answer: A

Rationale: The correct answer is A: Potassium level. Hypokalemia increases the risk of digoxin toxicity. Digoxin can potentiate the effects of low potassium levels, leading to life-threatening arrhythmias. Therefore, it is essential to review the patient's potassium level before administering digoxin. Choices B, C, and D are incorrect because calcium level, hemoglobin level, and white blood cell count are not directly related to the risk of digoxin toxicity.

Correct Answer: D

Rationale: TENS is a portable treatment that can be done at home, so the client should not expect to remain in the hospital for this treatment.

Correct Answer: B

Rationale: The correct answer is B. Reporting a cough is crucial when taking lisinopril as it can be a sign of a serious side effect, such as angioedema or cough associated with ACE inhibitors. Option A is incorrect because lisinopril can be taken with or without food. Option C is incorrect as facial swelling is not an expected side effect of lisinopril. Option D is incorrect because lisinopril can cause hyperkalemia, so increasing potassium-rich foods without healthcare provider guidance can be dangerous.

Correct Answer: B

Rationale: The correct therapeutic technique recommended for clients with somatic symptom disorder is to limit the amount of time the client spends discussing symptoms. By doing so, the focus can be shifted away from the illness, helping the client to manage their condition better. Encouraging complete bed rest (Choice A) is not typically recommended as it may reinforce illness behaviors. Monitoring the client's food intake (Choice C) may not directly address the psychological aspects of somatic symptom disorder. Educating the client on lifestyle changes (Choice D) is important but may not be as effective initially as limiting symptom-focused discussions.

Correct Answer: A

Rationale: The correct actions the nurse should take when caring for a client postoperative following a cholecystectomy and reporting pain include changing the client's position. This can help relieve postoperative pain by reducing pressure on the surgical site. Identifying the client's pain level is important but not specific to alleviating postoperative pain. While reminding the client to use incisional splinting can be beneficial, it may not directly address the immediate pain concern. Offering the client a back rub is not typically indicated for postoperative pain relief after a cholecystectomy.
