Correct Answer: A

Rationale: The correct answer is A: Irritability, confusion, restlessness. These are common signs of Increased Intracranial Pressure (IICP) as they result from the increased pressure on brain tissue. Choices B, C, and D are incorrect. Fatigue and shortness of breath (SOB) are not typical symptoms of IICP. Changes in pupillary response can be seen in other conditions but are not specific to IICP. Elevated blood pressure is not a common sign of IICP.

Correct Answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the appropriate action is to lower the height of the enema solution container. This adjustment helps alleviate the cramping by reducing the pressure of the solution entering the colon. Stopping the procedure and removing the tubing (Choice B) is not necessary unless there are other complications. Continuing the enema at a slower rate (Choice C) may not address the immediate discomfort caused by cramping. Increasing the flow of the enema solution (Choice D) can exacerbate the cramping and should be avoided.

Correct Answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

Correct Answer: A

Rationale: The correct answer is A. Thrombotic strokes typically have a gradual onset over minutes to hours as they result from a clot obstructing blood flow. Choice B, numbness on one side of the body, is more commonly associated with an ischemic stroke rather than specifically a thrombotic stroke. Choice C, loss of consciousness, is not a defining characteristic of a thrombotic stroke. Choice D, seizures and convulsions, are more commonly seen in hemorrhagic strokes rather than thrombotic strokes.

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.
