1. 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.

2. A nurse misreads a glucose level and administers insulin for a blood glucose of 210 mg/dL instead of 120 mg/dL. What is the priority intervention?

A. Monitor for hypoglycemia
B. Monitor for hyperkalemia
C. Administer glucose IV
D. Document the incident

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. In this scenario, the nurse administered insulin based on a misread glucose level, which could lead to hypoglycemia due to excessive insulin action lowering blood glucose levels. Monitoring for hypoglycemia allows for prompt recognition and intervention if blood glucose levels drop significantly. Choice B, monitoring for hyperkalemia, is incorrect as administering insulin would not cause hyperkalemia. Choice C, administering glucose IV, is not appropriate at this time since the patient's blood glucose level is already elevated. Choice D, documenting the incident, is important but not the priority at this moment when patient safety is at risk due to potential hypoglycemia.

3. What are the expected findings in a patient experiencing hypokalemia?

A. Flattened T waves on an ECG
B. Elevated ST segments
C. Prominent U waves
D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

4. What is the primary concern for a patient with a CD4 T-cell count below 180 cells/mm³?

A. Increased risk of severe infection
B. Increased risk of anemia
C. Increased risk of bleeding
D. Increased risk of dehydration

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm³ indicates a severely immunocompromised state, leading to an increased risk of severe infection. In individuals with low CD4 counts, the immune system is significantly weakened, making them more susceptible to opportunistic infections. Anemia (choice B), bleeding (choice C), and dehydration (choice D) are not the primary concerns associated with a low CD4 T-cell count. While these conditions may occur as secondary effects or complications, the primary focus is on preventing and managing severe infections in patients with severely compromised immune systems.

5. What are the expected changes on an ECG for a patient with hypokalemia?

A. Flattened T waves
B. Prominent U waves
C. ST elevation
D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.
