Nursing Elites

1. A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?

• A. PT
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications. Choice A (PT) is incorrect as it is used to monitor warfarin therapy, not heparin. Choice C (INR) is also incorrect as it is primarily used to monitor warfarin therapy. Choice D (Platelet count) is not directly related to monitoring the effectiveness of heparin therapy.

2. A client is receiving treatment with bevacizumab. Which of the following findings should the nurse monitor?

• A. Hypertension
• B. Hypokalemia
• C. Hyperglycemia
• D. Hypocalcemia

Correct answer: A

Rationale: Corrected Rationale: Bevacizumab is known to potentially cause hypertension as a common adverse effect. The nurse should monitor the client's blood pressure regularly to detect and manage any elevations effectively. Choices B, C, and D are incorrect because bevacizumab is not typically associated with causing hypokalemia, hyperglycemia, or hypocalcemia. Therefore, monitoring for hypertension is the priority in this case.

3. When using Nitroglycerine (transdermal), how many hours should you be nitrate-free each day?

• A. 1-2 hours
• B. 5-10 hours
• C. 3-4 hours
• D. 10-12 hours

Correct answer: D

Rationale: When using Nitroglycerine (transdermal), it should be applied for 10-12 hours per day to ensure its effectiveness. A nitrate-free period within the day is essential to prevent the development of tolerance to the medication.

4. A healthcare provider is caring for a client who is prescribed Digoxin. Which of the following laboratory values should the provider monitor to assess for potential toxicity?

• A. Sodium
• B. Potassium
• C. Magnesium
• D. Calcium

Correct answer: B

Rationale: The correct answer is to monitor the client's potassium levels. Hypokalemia can increase the risk of Digoxin toxicity. Potassium levels should be closely monitored to prevent adverse effects. Monitoring sodium levels is not directly related to Digoxin toxicity. While magnesium and calcium are important electrolytes, potassium levels are more critical for Digoxin toxicity assessment.

5. A client is being taught about a new prescription for Celecoxib. Which of the following information should be included in the teaching?

• A. Increases the risk for a myocardial infarction
• B. Decreases the risk of stroke
• C. Inhibits COX-1
• D. Increases platelet aggregation

Correct answer: A

Rationale: The correct answer is A: 'Increases the risk for a myocardial infarction.' Celecoxib, a COX-2 inhibitor, increases the risk for a myocardial infarction due to its effect on suppressing vasodilation, which can lead to this adverse cardiovascular event. Choices B, C, and D are incorrect. Celecoxib does not decrease the risk of stroke, inhibit COX-1, or increase platelet aggregation. It's crucial for the nurse to educate the client about the increased risk for a myocardial infarction when taking Celecoxib and emphasize monitoring for signs of heart issues and the importance of seeking prompt medical attention if symptoms occur.
