Correct Answer: A

Rationale: The correct answer is A: CD4 T-cell count 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV to assess the status of their immune system. A CD4 count of 180 cells/mm3 indicates severe immunocompromise and a high risk of opportunistic infections. This value is used to guide treatment decisions and assess the need for prophylaxis against specific infections. Choices B, C, and D are incorrect because monitoring white blood cell count, potassium levels, and hemoglobin levels, although important in HIV patients, are not as crucial as monitoring the CD4 T-cell count for assessing immune function and disease progression.

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the nurse should tighten the connections of the chest tube system. This action can often resolve an air leak causing the continuous bubbling. Clamping the chest tube or replacing it would not address the underlying issue of an air leak and may lead to complications. Continuing to monitor the chest tube without taking corrective action may result in the deterioration of the patient's condition.

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. Potassium-rich foods can exacerbate gastritis symptoms by irritating the stomach lining. Sodium (choice B) is not directly related to gastritis symptoms. Increasing exercise (choice C) can be beneficial for overall health but may not directly impact gastritis. Drinking milk (choice D) can provide temporary relief for some individuals with gastritis due to its coating effect, but it is not a universal recommendation as it can worsen symptoms in some cases.

Correct Answer: A

Rationale: Corrected Question: During an escharotomy on a patient with a burn injury, the purpose of this procedure is to release pressure and improve circulation in the affected area. This intervention is crucial in severe burns where the formation of eschar (dead tissue) can lead to increased pressure, compromising circulation and potentially causing further tissue damage. Choices B, C, and D are incorrect because escharotomy specifically aims to address pressure and circulation issues in severe burn injuries, rather than removing dead tissue, improving breathing, or preventing infection.

Correct Answer: A

Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. Excessive phosphorus intake can be harmful to individuals with kidney disease as their kidneys may not be able to excrete it efficiently. Choice B is incorrect because increasing sodium intake is generally not recommended for patients with kidney disease, as it can contribute to fluid retention and high blood pressure. Choice C is incorrect as protein restriction is commonly advised for individuals with advanced kidney disease to reduce the workload on the kidneys. Choice D is also incorrect as increasing protein intake can further burden the kidneys.
