1. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
2. A client with angina asks about obtaining a prescription for sildenafil to treat erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide is an organic nitrate used to manage angina. Concurrent use of sildenafil with organic nitrates, like isosorbide, is contraindicated due to the risk of fatal hypotension. It is essential for clients to avoid taking nitrate medications within 24 hours of using isosorbide to prevent serious complications.
3. A healthcare provider is providing discharge instructions to a client who is prescribed Prednisone. Which of the following dietary instructions should the healthcare provider include?
- A. Increase your intake of potassium-rich foods.
- B. Increase your intake of dairy products.
- C. Avoid foods high in vitamin K.
- D. Decrease your intake of protein.
Correct answer: A
Rationale: The correct answer is to increase the intake of potassium-rich foods (Choice A). Prednisone can cause potassium depletion, so clients should increase their intake of foods such as bananas, oranges, and spinach. Potassium-rich foods help maintain electrolyte balance and prevent complications associated with low potassium levels, such as muscle weakness and irregular heartbeats. Choices B, C, and D are incorrect because increasing dairy products (Choice B) or avoiding foods high in vitamin K (Choice C) are not specifically related to Prednisone therapy. Decreasing protein intake (Choice D) is also not necessary in this case.
4. A client has a new prescription for Digoxin to treat heart failure. Which of the following instructions should the nurse include in the teaching?
- A. Contact the provider if the heart rate is less than 60/min.
- B. Check the pulse rate for 30 seconds and multiply the result by 2.
- C. Increase the intake of sodium.
- D. Take with food if nausea occurs.
Correct answer: A
Rationale: The correct answer is A. It is crucial for clients on Digoxin to monitor their heart rate. A heart rate less than 60/min can indicate bradycardia, a potential side effect of Digoxin. Therefore, the client should be instructed to contact the provider if their heart rate is less than 60/min to prevent complications and receive appropriate management. Choices B, C, and D are incorrect. Checking the pulse rate for 30 seconds and multiplying by 2 is not specific to Digoxin administration. Increasing sodium intake is contraindicated as Digoxin can lead to sodium retention. Taking Digoxin with food if nausea occurs is not recommended as it may affect the drug's absorption.
5. A patient is being discharged with a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take the medication before bedtime.
- B. Monitor for increased blood pressure.
- C. Take the medication with food.
- D. Monitor for leg cramps.
Correct answer: D
Rationale: The correct instruction the nurse should include is to monitor for leg cramps. Leg cramps can be a sign of hypokalemia, which is a potential adverse effect of Hydrochlorothiazide. By monitoring for leg cramps, the patient can detect signs of low potassium levels and report them to the healthcare provider promptly. This proactive approach helps prevent complications associated with hypokalemia. The other options are incorrect because taking Hydrochlorothiazide before bedtime or with food is not specific to the medication's adverse effects. Monitoring for increased blood pressure is not typically a common adverse effect of this medication.
