Correct Answer: A

Rationale: The signs and symptoms of compartment syndrome include unrelieved pain, pallor, and pulselessness. Unrelieved pain is a key characteristic, indicating tissue ischemia due to increased pressure within a closed anatomic space. Pallor results from compromised blood flow, and pulselessness indicates severe ischemia requiring immediate intervention. Choices B, C, and D are incorrect because localized redness and swelling, fever and infection, and loss of sensation are not specific signs of compartment syndrome. Therefore, the correct answer is A.

Correct Answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it serves as a key indicator of immune function. A count below 180 cells/mm3 indicates severe immunocompromise and an increased risk of opportunistic infections. Choice B, serum albumin levels, though important for assessing nutritional status, is not the priority lab value for HIV monitoring. Choice C, white blood cell count, is a nonspecific measure of immune function and may not accurately reflect the status of the immune system in HIV patients. Choice D, hemoglobin levels, are essential for evaluating anemia but are not the primary lab value for monitoring HIV.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid items like mint that increase gastric acid secretion.' Mint can relax the lower esophageal sphincter, leading to increased gastric acid secretion and worsening GERD symptoms. Choice B is a good recommendation for GERD management as it helps prevent excessive stomach distension. Choice C is also a recommended practice to avoid reflux during sleep. Choice D, avoiding black and red pepper, is not directly linked to exacerbating GERD symptoms, so it is not the most relevant recommendation for a patient diagnosed with GERD.

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 priority action when the nurse administers insulin for a misread blood glucose reading is to monitor for signs of hypoglycemia. Insulin administration based on a misread blood glucose could lead to hypoglycemia due to an unnecessary dose. Monitoring for signs of hypoglycemia is crucial for prompt intervention if blood glucose levels drop dangerously low. Option B, monitoring for hyperglycemia, is incorrect in this situation as the concern is over-treatment with insulin causing hypoglycemia. Option C, administering glucose IV, is only necessary if hypoglycemia occurs. Option D, documenting the incident, is important for reporting and learning purposes but is not the immediate priority when the focus is on patient safety and preventing complications.
