Nursing Elites

1. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?

• A. Hypokalemia
• B. Hypernatremia
• C. Hypochloremia
• D. Hypercalcemia

Correct answer: A

Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.

2. The nurse is assisting in the care of a client with a history of chronic obstructive pulmonary disease (COPD) who is on oxygen therapy. Which action should the nurse take to ensure the client's safety?

• A. Set the oxygen flow rate to 4 liters per minute.
• B. Remove oxygen while the client is eating.
• C. Ensure the client wears a nasal cannula instead of a face mask.
• D. Maintain the oxygen flow rate at the lowest level that relieves hypoxia.

Correct answer: D

Rationale: For clients with COPD, too much oxygen can suppress their drive to breathe, leading to hypoventilation. Therefore, the nurse should maintain the oxygen flow rate at the lowest level that relieves hypoxia to prevent complications while ensuring adequate oxygenation. Setting the oxygen flow rate too high (Choice A) can be detrimental for the client with COPD. Removing oxygen while the client is eating (Choice B) can compromise oxygenation, which is essential even during meals. While nasal cannulas are commonly used, the choice of oxygen delivery device depends on the client's needs; there may be situations where a face mask (Choice C) is more appropriate.

3. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should reinforce which instruction?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of high-fiber foods.
• D. Avoid protein-rich foods.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.

4. A client has a new prescription for captopril. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Monitor for signs of hypokalemia.
• C. Take the medication at bedtime.
• D. Monitor for a dry cough.

Correct answer: D

Rationale: The correct answer is to monitor for a dry cough. Captopril is known to cause a persistent dry cough as a common side effect. If a dry cough develops, it should be reported to the healthcare provider promptly, as it may necessitate discontinuation of the medication. Choice A is incorrect because captopril is usually taken on an empty stomach. Choice B is incorrect as hypokalemia is not a common side effect of captopril. Choice C is incorrect as captopril is typically taken during the day and not specifically at bedtime.

5. The nurse is caring for a client who has returned to the unit after undergoing a cardiac catheterization. The nurse should monitor for which common complication following this procedure?

• A. Hypertension
• B. Hypotension
• C. Hemorrhage
• D. Hyperglycemia

Correct answer: C

Rationale: Following a cardiac catheterization, a common complication to monitor for is bleeding or hemorrhage at the catheter insertion site. Hemorrhage is a significant concern due to the potential for rapid blood loss, leading to hypovolemic shock and other serious complications. Monitoring for signs of bleeding, such as swelling, hematoma, or drop in hemoglobin levels, is crucial for timely intervention. Hypertension is not a common complication post-cardiac catheterization; instead, hypotension may occur due to vasovagal response or bleeding. Hyperglycemia is not typically associated with cardiac catheterization unless the client has pre-existing diabetes or stress-induced hyperglycemia.
