Nursing Elites

1. After returning the client to bed following a cardiac catheterization procedure with the left femoral vessel as the access site, the nurse places a sign above the bed instructing the client to remain on bed rest and in which position?

• A. In semi-Fowler's position
• B. With the head of the bed elevated 45 degrees
• C. With the head of the bed elevated no more than 15 degrees
• D. With the foot of the bed elevated as much as tolerated by the client

Correct answer: C

Rationale: After cardiac catheterization via the femoral vessel, it is crucial to keep the head of the bed elevated no more than 15 degrees to prevent bleeding at the access site. This position helps maintain pressure on the femoral artery, reducing the risk of bleeding and complications post-procedure. Choices A, B, and D are incorrect because they do not provide the necessary pressure on the femoral artery to prevent bleeding, which is essential after a cardiac catheterization procedure with a femoral access site.

2. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

• A. Tall, peaked T waves
• B. ST-segment depression
• C. Prolonged P-R interval
• D. Widening of the QRS complex

Correct answer: B

Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.

3. A client receives discharge teaching for a new prescription of lithium. Which instruction should be included?

• A. Take the medication with food.
• B. Increase your intake of sodium.
• C. Monitor for signs of hypercalcemia.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct instruction to include when a client receives discharge teaching for a new prescription of lithium is to increase their intake of sodium. Lithium can lead to decreased sodium levels, putting the individual at risk of developing hyponatremia. By increasing sodium intake, the client can counteract this risk, maintain a proper sodium balance, and prevent complications. Choices A, C, and D are incorrect because taking lithium with food, monitoring for signs of hypercalcemia, and avoiding dairy products are not directly related to managing the side effects or risks associated with lithium therapy.

4. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor to assess the effectiveness of the medication?

• A. Activated partial thromboplastin time (aPTT)
• B. Prothrombin time (PT) and international normalized ratio (INR)
• C. Platelet count
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are the laboratory values used to monitor the effectiveness of warfarin therapy. These values help ensure that the client is within the therapeutic range for anticoagulation. PT measures the time it takes for blood to clot, while INR standardizes PT results to minimize variations between laboratories. Monitoring these values is crucial to prevent complications such as bleeding or clot formation. Activated partial thromboplastin time (aPTT) (Choice A) is more commonly used to monitor heparin therapy. Platelet count (Choice C) assesses the number of platelets in the blood and is not specific to warfarin therapy. Erythrocyte sedimentation rate (ESR) (Choice D) is a non-specific marker of inflammation and is not used to monitor the effectiveness of warfarin therapy.

5. A client with chronic heart failure has been prescribed furosemide (Lasix). Which instruction should the nurse reinforce to the client regarding this medication?

• A. Take the medication with food.
• B. Limit foods high in potassium while taking this medication.
• C. Report any muscle cramps or weakness to your healthcare provider.
• D. Expect to urinate more frequently while on this medication.

Correct answer: C

Rationale: The correct instruction for the nurse to reinforce to the client regarding furosemide (Lasix) is to report any muscle cramps or weakness to the healthcare provider. Muscle cramps or weakness may indicate hypokalemia, a potential side effect of furosemide. Monitoring and reporting these symptoms promptly can help in preventing complications related to electrolyte imbalances. Choice A is incorrect because furosemide should be taken on an empty stomach. Choice B is not directly related to furosemide use; in fact, foods high in potassium may be beneficial for clients taking furosemide to prevent hypokalemia. Choice D is a common expected side effect of furosemide due to its diuretic action but is not as crucial to report as potential signs of electrolyte imbalances.
