Correct Answer: A

Rationale: The correct answer is to limit phosphorus intake to 700 mg/day for a patient with pre-dialysis end-stage kidney disease. Excessive phosphorus intake can lead to further complications in kidney disease, such as bone and cardiovascular issues. Choice B is incorrect as increasing protein intake can put additional stress on the kidneys due to the buildup of urea and other waste products. Choice C is incorrect because increasing sodium intake can worsen hypertension and fluid retention, common issues in kidney disease. Choice D is incorrect as limiting sodium intake is generally recommended in kidney disease to manage blood pressure and fluid balance.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid alcohol.' Alcohol consumption can exacerbate dehydration in patients with diabetes insipidus, so it is essential to advise them to avoid alcohol. Monitoring serum albumin levels (choice A) is not directly related to managing diabetes insipidus. Teaching the patient to increase fluids (choice C) is not recommended as it can worsen the condition by further diluting the urine. Increasing exercise to reduce stress (choice D) is not a primary intervention for managing diabetes insipidus.

Correct Answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority nursing action for a patient with chest pain and possible acute coronary syndrome. Nitroglycerin helps dilate the blood vessels, improve blood flow to the heart, and reduce cardiac workload. This action aims to relieve chest pain promptly and prevent further cardiac tissue damage. Increasing fluids is not the initial priority for a patient with chest pain and possible acute coronary syndrome. Obtaining cardiac enzymes is important for diagnosis but is not the first action in managing acute symptoms. Getting IV access and auscultating heart sounds are important interventions, but they come after administering sublingual nitroglycerin in the management of acute coronary syndrome.

Correct Answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps relieve chest pain by dilating blood vessels and improving blood flow to the heart, which is crucial in managing acute coronary syndrome. While obtaining IV access and checking cardiac enzymes are important steps in the assessment and management of acute coronary syndrome, administering nitroglycerin takes precedence to alleviate symptoms and reduce cardiac tissue damage. Administering aspirin is also essential in the treatment of acute coronary syndrome, but it is not the immediate priority in this scenario.
