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. A nurse is teaching a group of assistive personnel (AP) about caring for clients who have Alzheimer's disease. Which of the following information should the nurse include in the teaching?

• A. Explain procedures clearly and concisely to the client before initiating care
• B. Encourage a client's engagement in appropriate activities to minimize emotional outbursts
• C. Speak calmly and at a moderate volume to a client who is unable to form words or sentences
• D. Provide supervision to prevent a client from becoming injured or lost

Correct answer: D

Rationale: The correct answer is D because clients with Alzheimer's disease are at risk of wandering and becoming lost. Providing supervision helps prevent them from getting injured or lost. Choice A is incorrect because extensive details may overwhelm clients with Alzheimer's. Choice B is incorrect because limiting activities can lead to boredom and behavioral issues. Choice C is incorrect because speaking calmly and at a moderate volume helps to reduce agitation and confusion in clients with Alzheimer's.

3. What is the priority action when the nurse administers insulin for a misread blood glucose reading?

• A. Monitor for signs of hypoglycemia
• B. Monitor for hyperglycemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: A

Rationale: The priority action when the nurse administers insulin for a misread blood glucose reading is to monitor for signs of hypoglycemia. Insulin administration based on a misread blood glucose could lead to hypoglycemia due to an unnecessary dose. Monitoring for signs of hypoglycemia is crucial for prompt intervention if blood glucose levels drop dangerously low. Option B, monitoring for hyperglycemia, is incorrect in this situation as the concern is over-treatment with insulin causing hypoglycemia. Option C, administering glucose IV, is only necessary if hypoglycemia occurs. Option D, documenting the incident, is important for reporting and learning purposes but is not the immediate priority when the focus is on patient safety and preventing complications.

4. A nurse misreads a blood glucose level and administers excess insulin. What should the nurse monitor for?

• A. Monitor for hyperglycemia
• B. Monitor for hypoglycemia
• C. Administer glucose IV
• D. Monitor for increased thirst

Correct answer: B

Rationale: The correct answer is to monitor for hypoglycemia. Excess insulin can lead to low blood glucose levels, causing hypoglycemia. Symptoms of hypoglycemia include sweating, trembling, dizziness, confusion, and in severe cases, loss of consciousness. Options A, C, and D are incorrect because administering excess insulin would not lead to hyperglycemia or increased thirst, and administering glucose IV would exacerbate the issue by further lowering blood glucose levels.

5. What is a characteristic sign of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.
