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. 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.

3. A client is taking furosemide. Which of the following findings should the nurse report to the provider?

• A. Weight gain
• B. Dry cough
• C. Hypokalemia
• D. Increased appetite

Correct answer: C

Rationale: Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. Hypokalemia is a serious electrolyte imbalance that can cause various cardiac and muscular issues. Therefore, the nurse should promptly report hypokalemia to the healthcare provider for appropriate management. Choices A, B, and D are incorrect because weight gain, dry cough, and increased appetite are not typically associated with furosemide use and are not immediate concerns that require urgent reporting.

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

• A. Take the medication with food.
• B. Expect red-orange discoloration of body fluids.
• C. Monitor for signs of hyperglycemia.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct answer is to inform the client to expect red-orange discoloration of body fluids when taking rifampin. Rifampin is known to cause this side effect, which is harmless but can be surprising to patients. It is important for the nurse to educate the client about this expected change to prevent unnecessary concern or alarm. Monitoring for hyperglycemia is not directly related to rifampin, and taking the medication with food or avoiding dairy products are not specific instructions for this medication.

5. A hypertensive client who has been taking metoprolol (Lopressor) has been prescribed to decrease the dose of the medication. The client asks the nurse why this must be done over a period of 1 to 2 weeks. In formulating a response, the nurse incorporates the understanding that abrupt withdrawal could affect the client in which way?

• A. Result in hypoglycemia
• B. Give the client insomnia
• C. Precipitate rebound hypertension
• D. Cause enhanced side effects of other prescribed medications

Correct answer: C

Rationale: Abruptly stopping metoprolol can lead to rebound hypertension, causing a sudden increase in blood pressure due to the sudden withdrawal of the medication. Gradually tapering the dose helps the body adjust and reduces the risk of this adverse effect. Choices A, B, and D are incorrect. Stopping metoprolol suddenly is not known to result in hypoglycemia, insomnia, or enhanced side effects of other medications.
