Nursing Elites

1. What ECG changes are seen with hyperkalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

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. When planning care for a patient with diabetes insipidus, what should the nurse include in the plan?

• A. Monitor serum albumin levels
• B. Avoid alcohol
• C. Teach the patient to increase fluids
• D. Increase exercise to reduce stress

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.

4. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. Drainage in the chest tube
• C. A blocked chest tube
• D. Normal chest tube function

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This signifies that air is escaping from the patient's pleural space into the chest tube system rather than being evacuated properly. An air leak can lead to lung collapse or pneumothorax and requires immediate attention. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because continuous bubbling does not indicate normal chest tube function, drainage in the chest tube, or a blocked chest tube.

5. What are the priority lab values to monitor in a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. White blood cell count
• C. Hemoglobin levels
• D. Serum albumin levels

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 indicates the level of immunocompromise. A CD4 count below 180 cells/mm3 is considered severe immunocompromise and requires close monitoring and intervention. Choices B, C, and D are not the priority lab values to monitor in HIV patients. While white blood cell count, hemoglobin levels, and serum albumin levels can provide valuable information about the patient's health status, they are not as specific or indicative of HIV disease progression and management as the CD4 T-cell count.
