Correct Answer: A

Rationale: The correct action for the nurse to take when a client with a history of angina reports chest pain is to administer sublingual nitroglycerin every 5 minutes. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain associated with angina. Aspirin is often given during a suspected heart attack, not for immediate relief of angina. Deep breathing exercises may be beneficial for anxiety or respiratory conditions but are not the first-line intervention for angina. Oxygen therapy is not the initial treatment for angina unless the client is hypoxic.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common sign of hypoglycemia due to the activation of the sympathetic nervous system. Tachycardia (choice A) is more commonly associated with hyperglycemia. Dry mouth (choice B) is not a typical finding in hypoglycemia but may be seen in hyperglycemia. Increased appetite (choice D) is not a typical sign of hypoglycemia and is more commonly associated with hyperglycemia.

Correct Answer: B

Rationale: The correct answer is B: Absence of a bruit. In a client with an arteriovenous fistula, the presence of a bruit (a humming sound) is an expected finding due to the high-pressure flow of blood through the fistula. Therefore, the absence of a bruit suggests a complication, such as thrombosis or stenosis, which should be reported for further evaluation and management. Choices A, C, and D are incorrect because a thrill upon palpation, distended blood vessels, and a swishing sound upon auscultation are expected findings in a client with an arteriovenous fistula and do not necessarily indicate a complication.

Correct Answer: C

Rationale: The correct answer is C, 'Serum creatinine 3.5 mg/dL.' An elevated serum creatinine level indicates worsening kidney function and impaired renal clearance, which should be reported to the provider promptly. Choice A, 'Blood urea nitrogen (BUN) 15 mg/dL,' is within the normal range (7-20 mg/dL) and does not indicate acute kidney injury. Choice B, 'Urine output of 45 mL/hr,' is a low urine output but does not directly reflect kidney function decline. Choice D, 'Calcium 9 mg/dL,' is within the normal calcium range (8.5-10.5 mg/dL) and is not specifically indicative of acute kidney injury.

Correct Answer: A

Rationale: The correct intervention the nurse should include in the care plan for a client with Alzheimer's disease is to provide reality orientation throughout the day. Reality orientation involves helping clients with Alzheimer's disease stay connected to the present, reducing confusion and disorientation. This intervention can help the client maintain a sense of time, place, and person. Choices B, C, and D are incorrect because limiting choices may lead to frustration, group therapy may not always be suitable for clients with Alzheimer's disease, and sensory stimulation activities may not address the core issue of disorientation in Alzheimer's disease.
