Correct Answer: B

Rationale: In a client with severe pain like the one described, the priority medication to administer is a potent analgesic like hydromorphone. Hydromorphone is a strong opioid pain medication that can effectively manage severe pain. Promethazine (Choice A) is an antiemetic and antihistamine, not a pain medication. Ketorolac (Choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that is contraindicated in end-stage renal disease due to its potential to cause kidney damage. Amitriptyline (Choice D) is a tricyclic antidepressant used for conditions like depression and neuropathic pain, but it is not the first-line treatment for severe acute pain.

Correct Answer: A

Rationale: The correct answer is to monitor serum creatinine. In patients with chronic kidney disease, monitoring serum creatinine is crucial as it reflects kidney function. This assessment helps healthcare providers in evaluating the progression of the disease and adjusting treatment plans accordingly. Monitoring blood pressure (choice B) is essential in managing chronic kidney disease, but monitoring serum creatinine takes precedence. Monitoring urine output (choice C) and potassium levels (choice D) are also important aspects of managing chronic kidney disease, but they are not the priority assessment compared to monitoring serum creatinine.

Correct Answer: A

Rationale: The most important nursing action when a patient has a central line is to monitor for infection. Central line-associated bloodstream infections are a serious complication that can lead to severe outcomes. Monitoring for infection involves assessing the patient for signs and symptoms such as fever, chills, and hypotension. While monitoring the central line dressing, redness, and swelling are also important aspects of care, they are secondary to monitoring for infection as the primary focus should be on preventing serious complications.

Correct Answer: C

Rationale: The correct answer is C because limiting saturated fat intake to 7% of daily calories is a crucial component of the dietary management for hypertension. This dietary modification helps reduce the risk of cardiovascular complications. Choices A, B, and D are incorrect. Choice A is incorrect because medication adherence should not be based on symptoms like dizziness. Choice B is inadequate as blood pressure monitoring should be more frequent, preferably daily, for effective management of hypertension. Choice D is incorrect because medication for hypertension should be taken consistently as prescribed, not just when symptoms occur.

Correct Answer: C

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A, avoiding prolonged exposure to sunlight, is not directly related to furosemide use. Choice B, taking the medication with a meal, is not a specific requirement for furosemide administration. Choice D, limiting fluid intake to 1 liter per day, is not the correct advice as furosemide is a diuretic that often requires increased fluid intake to prevent dehydration.
