Nursing Elites

1. 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.

2. What is the priority lab value for monitoring a patient with HIV?

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

3. A client scheduled for electromyography (EMG) will have small needle electrodes inserted into the muscles. What should the nurse include in the teaching?

• A. You will receive a fixed dose of radioisotope 2 hours before the procedure.
• B. Momentary flushing will occur at the beginning of the procedure.
• C. You should inform your provider if you are claustrophobic.
• D. You should expect insertion of small needle electrodes into the muscles.

Correct answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to assess muscle weakness and nerve responses. Choices A, B, and C are incorrect because radioisotope is not used in EMG, flushing is not a typical occurrence, and claustrophobia is more relevant for imaging procedures like MRI or CT scans, not EMG.

4. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

5. What is the primary nursing action for a patient experiencing continuous bubbling in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Continue monitoring the chest tube
• D. Replace the chest tube system

Correct answer: A

Rationale: The correct answer is to tighten the connections of the chest tube system. Continuous bubbling in the chest tube water seal chamber indicates an air leak. By tightening the connections of the chest tube system, the nurse can often resolve the issue by ensuring there are no loose connections allowing air to enter. Clamping the chest tube or replacing the chest tube system are not appropriate actions in this situation. Clamping the tube can cause a dangerous buildup of pressure, while replacing the system should only be considered if tightening the connections does not resolve the air leak.
