1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?
- A. Platelet count.
- B. Prothrombin time (PT) and international normalized ratio (INR).
- C. Activated partial thromboplastin time (aPTT).
- D. Fibrinogen level.
Correct answer: B
Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.
2. A client who is receiving heparin therapy has an activated partial thromboplastin time (aPTT) of 90 seconds. What action should the nurse take?
- A. Increase the heparin infusion rate.
- B. Notify the healthcare provider.
- C. Apply pressure to the injection site.
- D. Administer protamine sulfate.
Correct answer: B
Rationale: An activated partial thromboplastin time (aPTT) of 90 seconds is elevated, indicating a risk of bleeding. The appropriate action for the nurse is to notify the healthcare provider. Increasing the heparin infusion rate can further elevate the aPTT, leading to an increased risk of bleeding. Applying pressure to the injection site is not relevant in this situation. Administering protamine sulfate is used to reverse the effects of heparin in cases of overdose or bleeding, but it is not the initial action for an elevated aPTT.
3. A client with osteoporosis is being discharged home. Which instruction should the nurse include in the discharge teaching?
- A. Avoid weight-bearing exercises.
- B. Take calcium supplements with meals.
- C. Limit vitamin D intake.
- D. Increase intake of caffeine-containing beverages.
Correct answer: B
Rationale: Taking calcium supplements with meals is a crucial instruction for a client with osteoporosis. Calcium absorption is enhanced when taken with food, and proper calcium intake is essential for managing osteoporosis effectively by promoting bone health and density. Avoiding weight-bearing exercises (Choice A) is incorrect because these exercises help improve bone strength. Limiting vitamin D intake (Choice C) is also incorrect as vitamin D is necessary for calcium absorption. Increasing caffeine intake (Choice D) is not recommended as caffeine can interfere with calcium absorption.
4. A client with chronic renal failure is prescribed epoetin alfa (Epogen). Which outcome indicates that the medication is effective?
- A. Increased urine output.
- B. Decreased blood pressure.
- C. Improved hemoglobin levels.
- D. Stable potassium levels.
Correct answer: C
Rationale: Epoetin alfa is a medication that stimulates red blood cell production. Therefore, in a client with chronic renal failure, an effective outcome of epoetin alfa therapy would be an improvement in hemoglobin levels. This indicates that the medication is working as intended by addressing anemia, a common complication of chronic renal failure. Increased urine output (choice A) is not directly related to the action of epoetin alfa. Decreased blood pressure (choice B) is not a primary expected outcome of epoetin alfa therapy. Stable potassium levels (choice D) are important but not a direct indicator of the effectiveness of epoetin alfa in this context.
5. A client with a history of gout is experiencing an acute attack. Which medication should the nurse expect the healthcare provider to prescribe?
- A. Aspirin.
- B. Allopurinol (Zyloprim).
- C. Colchicine.
- D. Probenecid (Benemid).
Correct answer: C
Rationale: During an acute gout attack, the healthcare provider is likely to prescribe colchicine. Colchicine is commonly used to treat acute gout attacks because it works by reducing inflammation and alleviating pain associated with the condition. It is important to note that aspirin is not recommended for gout treatment and may even exacerbate the symptoms. Allopurinol and probenecid are medications used for long-term management of gout by reducing uric acid levels in the blood, but they are not typically prescribed during an acute attack. Therefore, colchicine is the most appropriate medication for managing an acute gout attack.
