Nursing Elites

1. The LPN/LVN is assisting in the care of a client with a diagnosis of heart failure who is receiving digoxin (Lanoxin). Which laboratory result should the nurse monitor closely?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum glucose

Correct answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure. Serum sodium, serum calcium, and serum glucose levels are also important laboratory values to monitor in clients with heart failure, but they are not directly associated with the risk of digoxin toxicity. Monitoring these values helps in assessing overall health status, fluid balance, and metabolic functions in the client.

2. A client with a history of coronary artery disease (CAD) is prescribed simvastatin (Zocor). The nurse should teach the client about which potential side effect?

• A. Muscle pain
• B. Dry mouth
• C. Drowsiness
• D. Diarrhea

Correct answer: A

Rationale: Muscle pain is a common side effect of statins like simvastatin and can indicate a serious condition called rhabdomyolysis. Rhabdomyolysis is a severe condition where muscle fibers break down rapidly, releasing myoglobin into the bloodstream, which can lead to kidney damage. Therefore, it's important for the nurse to educate the client about this potential side effect and to promptly report any muscle pain to the healthcare provider. Dry mouth, drowsiness, and diarrhea are not commonly associated with simvastatin use and are less concerning compared to the risk of rhabdomyolysis.

3. A healthcare provider is assisting in the care of a client who is having central venous pressure (CVP) measurements taken. The healthcare provider should assist by placing the bed in which position for the reading?

• A. Flat
• B. Semi-Fowler's
• C. Trendelenburg
• D. Reverse Trendelenburg

Correct answer: A

Rationale: Central venous pressure (CVP) measurements are most accurate when the client is lying flat, as this allows for a consistent baseline. Placing the bed flat ensures that the hydrostatic pressure within the vena cava is not affected by the client's position, providing a more precise reading. Choice B (Semi-Fowler's) elevates the head of the bed at a 30-45 degree angle, which could affect the accuracy of CVP readings. Choices C (Trendelenburg) and D (Reverse Trendelenburg) involve extreme positions that would not be suitable for obtaining accurate CVP measurements.

4. A client is receiving heparin therapy. Which of the following laboratory tests should be monitored to evaluate the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Complete blood count (CBC)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the most appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works on the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps assess its anticoagulant effect. Therapeutic levels of aPTT for clients on heparin therapy are typically 1.5 to 2.5 times the control value. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, which acts on the extrinsic pathway of the coagulation cascade. Complete blood count (CBC) is not specific for monitoring the effectiveness of heparin therapy.

5. The healthcare provider is reinforcing instructions to a client with heart failure who is prescribed a low-sodium diet. The provider should advise the client to choose which food item?

• A. Canned soup
• B. Fresh vegetables
• C. Processed cheese
• D. Pickled vegetables

Correct answer: B

Rationale: Fresh vegetables are a suitable choice for clients on a low-sodium diet as they are naturally low in sodium and provide essential nutrients. In contrast, canned soup, processed cheese, and pickled vegetables tend to be high in sodium, which is not recommended for individuals with heart failure and on a low-sodium diet. Fresh vegetables are also rich in fiber, vitamins, and minerals, making them a healthier option compared to the other choices provided.
