Nursing Elites

1. The client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Serum electrolytes
• D. Liver function tests

Correct answer: B

Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor the effectiveness of anticoagulant therapy, especially with heparin. A prolonged aPTT indicates effective anticoagulation, reducing the risk of further clot formation in the client with deep vein thrombosis (DVT). The other options, such as complete blood count (CBC), serum electrolytes, and liver function tests, do not directly assess the therapeutic effectiveness of anticoagulant therapy. Therefore, the correct answer is B.

2. The LPN/LVN is assisting in the care of a client with chronic heart failure who is receiving furosemide (Lasix). Which instruction should the nurse reinforce with the client?

• A. Limit your fluid intake to avoid fluid overload.
• B. Increase your potassium intake by eating bananas and oranges.
• C. Weigh yourself once a week to monitor for fluid retention.
• D. Take the medication at night to avoid frequent urination during the day.

Correct answer: B

Rationale: The correct instruction for the nurse to reinforce with the client is to increase potassium intake by eating bananas and oranges. Furosemide can lead to potassium loss, potentially causing hypokalemia. By increasing potassium intake through diet, the client can help prevent this electrolyte imbalance and maintain overall health. Choices A, C, and D are incorrect. Limiting fluid intake is not the appropriate instruction, as furosemide is a diuretic that already helps in fluid management. Weighing once a week is not as crucial as monitoring potassium levels, and taking the medication at night does not impact potassium levels.

3. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

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

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.

4. The nurse is teaching a client about lifestyle changes to manage hypertension. Which dietary change should the nurse recommend?

• A. Increase intake of red meat
• B. Use salt substitutes liberally
• C. Limit sodium intake to 2 grams per day
• D. Increase intake of processed foods

Correct answer: C

Rationale: The correct answer is C: 'Limit sodium intake to 2 grams per day.' This recommendation is crucial in managing hypertension because excessive sodium intake can lead to elevated blood pressure. Reducing sodium intake helps the body regulate fluid balance and lower blood pressure. Choices A, B, and D are incorrect. Increasing red meat intake can worsen hypertension due to its high saturated fat content. Using salt substitutes liberally can also be harmful as they often contain high amounts of potassium, which can be problematic for individuals with certain health conditions. Increasing processed foods consumption is generally discouraged in hypertension management due to their high sodium content and low nutritional value.

5. A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?

• A. Take the medication at the same time each day.
• B. Avoid foods high in potassium.
• C. Skip a dose if you feel well.
• D. Take the medication on an empty stomach.

Correct answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm. Choices B, C, and D are incorrect because avoiding potassium-rich foods, skipping doses when feeling well, and taking the medication on an empty stomach are not relevant or appropriate instructions for a client prescribed digoxin.
