Nursing Elites

1. The client is receiving heparin therapy for deep vein thrombosis (DVT). Which lab test should be monitored to evaluate the effectiveness of heparin?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Fibrinogen levels

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate lab test to monitor the therapeutic effectiveness of heparin therapy. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure the client is within the therapeutic range to prevent clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, a different anticoagulant that affects the extrinsic pathway of the coagulation cascade. Fibrinogen levels are not specific to monitoring heparin therapy.

2. When teaching a client with a new prescription for spironolactone, which instruction should the nurse include?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take the medication with food.
• D. Monitor for signs of hyperkalemia.

Correct answer: D

Rationale: The correct answer is to instruct the client to monitor for signs of hyperkalemia when taking spironolactone since it is a potassium-sparing diuretic. Hyperkalemia is a potential adverse effect due to the medication's mechanism of action. Advising the client to increase potassium-rich foods (Choice A) would be incorrect as it can further elevate potassium levels, which could lead to hyperkalemia. Avoiding grapefruit juice (Choice B) is not directly related to spironolactone use. Though taking the medication with food (Choice C) can help reduce gastrointestinal upset, it is not the most critical instruction when initiating spironolactone therapy.

3. The client is reinforcing instructions for a low-sodium diet. Which statement by the client indicates a need for further teaching?

• A. I will avoid adding salt to my food while cooking.
• B. I will use salt substitutes instead of regular salt.
• C. I can eat as much processed food as I like since it's usually low in sodium.
• D. I will read food labels to check for sodium content.

Correct answer: C

Rationale: The correct answer is C. Processed foods often contain high amounts of sodium, so they should be limited or avoided on a low-sodium diet. Choosing processed foods can lead to increased sodium intake, counteracting the purpose of following a low-sodium diet. Option A shows an understanding of avoiding added salt, Option B suggests using alternatives to regular salt, and Option D indicates a willingness to check food labels for sodium content, all of which are appropriate for a low-sodium diet. Therefore, the client's statement about eating processed foods freely is incorrect and requires further teaching.

4. A healthcare professional is assessing a client who has been taking isoniazid to treat tuberculosis. The healthcare professional should monitor the client for which of the following findings as an adverse effect of the medication?

• A. Diarrhea
• B. Blurred vision
• C. Hearing loss
• D. Jaundice

Correct answer: D

Rationale: Correct. Jaundice is a serious adverse effect of isoniazid due to liver damage. It is essential to monitor for signs of liver toxicity, such as jaundice, while the client is on this medication. Diarrhea is a common side effect of isoniazid, but it is not as serious as liver damage. Blurred vision and hearing loss are not typically associated with isoniazid use.

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

• A. Take the medication with food.
• B. Monitor for signs of hypoglycemia.
• C. Increase fluid intake.
• D. Expect a metallic taste in the mouth.

Correct answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration can also help reduce the risk of kidney problems associated with metformin use. Choices A, B, and D are incorrect. While it's generally recommended to take metformin with food to reduce stomach upset, monitoring for signs of hypoglycemia is more relevant for other antidiabetic medications, and a metallic taste in the mouth is not a common side effect of metformin.
