1. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.

2. What ECG changes should be monitored in a patient with hypokalemia?

• A. Flattened T waves and prominent U waves
• B. Elevated ST segments and wide QRS complexes
• C. Tall T waves and flattened QRS complexes
• D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

3. What should be monitored in a patient with diabetes insipidus?

• A. Monitor urine specific gravity for values below 1.005
• B. Monitor for increased thirst
• C. Monitor serum albumin levels
• D. Monitor blood pressure closely

Correct answer: A

Rationale: In a patient with diabetes insipidus, monitoring urine specific gravity for values below 1.005 is crucial. Low urine specific gravity indicates excessive water loss, a key characteristic of diabetes insipidus. Monitoring for increased thirst (choice B) may be a symptom presented by the patient, but it does not directly reflect the condition's severity. Monitoring serum albumin levels (choice C) is not typically associated with diabetes insipidus. Monitoring blood pressure closely (choice D) is not a primary concern in diabetes insipidus unless severe dehydration leads to hypotension.

4. What intervention is needed for a patient with a chest tube and an air leak?

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

Correct answer: A

Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.

5. 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.
