1. 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.

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. A patient with pre-dialysis end-stage kidney disease is asking for dietary recommendations. What should the nurse suggest?

• A. Limit protein intake
• B. Limit potassium intake
• C. Restrict sodium intake
• D. Limit phosphorus intake to 700mg/day

Correct answer: D

Rationale: In patients with pre-dialysis end-stage kidney disease, it is crucial to limit phosphorus intake to 700mg/day to manage their condition. High phosphorus levels can lead to complications such as bone and heart problems. Limiting protein intake is essential in later stages of kidney disease, particularly in dialysis patients to reduce the buildup of waste products. While limiting potassium and restricting sodium intake are also important in kidney disease management, the priority for a patient with pre-dialysis end-stage kidney disease is to control phosphorus levels.

4. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

5. A patient with ventricular tachycardia and a pulse needs electrical intervention. What is the appropriate action?

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

Correct answer: B

Rationale: For a patient with ventricular tachycardia and a pulse, the appropriate action is synchronized cardioversion. Defibrillation is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing is typically used for bradycardias. Medication administration may be considered in stable ventricular tachycardia cases but electrical intervention is preferred for immediate correction in this scenario.
