1. What is the expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

2. A client is to undergo a liver biopsy. Which of the following instructions should the nurse provide to the client following the procedure?

• A. Lie on your left side.
• B. Lie on your right side.
• C. Increase your fluid intake.
• D. Decrease your fluid intake.

Correct answer: B

Rationale: After a liver biopsy, the nurse should instruct the client to lie on the right side. This position helps apply pressure to the biopsy site, promoting hemostasis and reducing the risk of bleeding. Lying on the left side may not provide adequate pressure to the site. Increasing fluid intake is generally beneficial to prevent dehydration and aid in the recovery process, whereas decreasing fluid intake could lead to dehydration and possible complications. Therefore, the correct instruction is to lie on the right side.

3. What lab value should be prioritized for 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: A CD4 T-cell count below 180 cells/mm3 should be prioritized for a patient with HIV. This value is crucial as it indicates severe immunocompromise in HIV-infected individuals. Monitoring CD4 T-cell count helps assess the status of the immune system and guides treatment decisions. Serum albumin levels (choice B) may reflect the patient's nutritional status and overall health but are not as specific to HIV disease progression. White blood cell count (choice C) and hemoglobin levels (choice D) can be affected by various factors and are not as directly linked to HIV management as the CD4 T-cell count in this context.

4. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

5. What should be monitored in a patient receiving insulin who is at risk for hypoglycemia?

• A. Monitor blood glucose levels
• B. Monitor for respiratory distress
• C. Monitor for hypertension
• D. Monitor for hyperkalemia

Correct answer: A

Rationale: Corrected Question: In a patient receiving insulin who is at risk for hypoglycemia, monitoring blood glucose levels is crucial. This helps in preventing and identifying hypoglycemia promptly. Choice B, monitoring for respiratory distress, is not directly related to hypoglycemia caused by insulin. Choice C, monitoring for hypertension, is not typically associated with hypoglycemia. Choice D, monitoring for hyperkalemia, is not a common concern in patients receiving insulin who are at risk for hypoglycemia.
