1. What is the priority lab value to monitor in a patient with HIV?

A. CD4 T-cell count 180 cells/mm3
B. White blood cell count 4,500/mm3
C. Potassium levels 3.5-5.0 mEq/L
D. Hemoglobin levels below 12g/dL

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.

2. What is a typical symptom of a hemorrhagic stroke in a patient?

A. Sudden, severe headache
B. Gradual onset of numbness
C. Loss of consciousness
D. Loss of speech ability

Correct answer: A

Rationale: A sudden, severe headache is a common symptom of a hemorrhagic stroke due to brain bleeding. This headache is often described as the worst headache of one's life. Gradual onset of numbness (choice B) is more characteristic of an ischemic stroke, where a blood clot blocks an artery in the brain. Loss of consciousness (choice C) can occur in severe cases of stroke but is not specific to hemorrhagic strokes. Loss of speech ability (choice D) is more associated with ischemic strokes affecting language centers of the brain.

3. A nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and is receiving 3% sodium chloride via continuous IV. Which of the following laboratory findings should the nurse identify as an indication that the SIADH is resolving?

A. Urine specific gravity 1.020
B. Sodium 119 mEq/L
C. BUN 8 mg/dL
D. Calcium 8.7 mg/dL

Correct answer: A

Rationale: A urine specific gravity of 1.020 is within the expected reference range and indicates that the kidneys are appropriately concentrating urine, which is a sign that the syndrome of inappropriate antidiuretic hormone (SIADH) is resolving. A low sodium level (choice B) is associated with SIADH, so a sodium level of 119 mEq/L is not indicative of resolution. BUN (choice C) and calcium levels (choice D) are typically not directly related to SIADH resolution.

4. What symptoms are associated with a thrombotic stroke?

A. Gradual loss of function on one side of the body
B. Sudden loss of consciousness
C. Loss of motor function with nausea
D. Severe headache and vomiting

Correct answer: A

Rationale: A thrombotic stroke presents with a gradual loss of function on one side of the body due to a clot blocking blood flow to the brain. This gradual onset distinguishes it from a hemorrhagic stroke with sudden symptoms like loss of consciousness (Choice B), and from other conditions like migraine, which may present with severe headache and vomiting (Choice D). Nausea (Choice C) is not typically a primary symptom associated with a thrombotic stroke.

5. What signs indicate increased intracranial pressure (IICP)?

A. Restlessness, irritability, and confusion
B. Sudden onset of seizures
C. Bradycardia and altered pupil response
D. Loss of consciousness

Correct answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.
