Nursing Elites

1. A nurse is planning care for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the therapy?

• A. Serum calcium level
• B. Platelet count
• C. INR
• D. WBC count

Correct answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

2. What is the most critical lab value to monitor for a patient on heparin therapy?

• A. Monitor aPTT levels
• B. Monitor platelet count
• C. Monitor INR levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.

3. A nurse is caring for a client who is receiving oxytocin IV for augmentation of labor. The client's contractions are occurring every 45 seconds with a nine-second duration, and the fetal heart rate is 170 to 180 beats per minute. Which of the following actions should the nurse take?

• A. Discontinue oxytocin infusion
• B. Increase oxytocin infusion
• C. Decrease oxytocin infusion
• D. Maintain oxytocin infusion

Correct answer: A

Rationale: In this scenario, the client is experiencing frequent contractions with a short duration and an elevated fetal heart rate, indicating potential fetal distress. Discontinuing the oxytocin infusion is crucial to prevent further complications and restore normal fetal parameters. Increasing or maintaining the oxytocin infusion could exacerbate the situation, leading to more distress for the fetus. Decreasing the oxytocin infusion may not be sufficient to address the current issue and could delay the improvement of fetal well-being.

4. A nurse is assessing a client who has hypovolemia. Which of the following findings should the nurse expect?

• A. Bradycardia.
• B. Tachycardia.
• C. Increased blood pressure.
• D. Bounding pulse.

Correct answer: B

Rationale: The correct answer is B: Tachycardia. In hypovolemia, the body responds to decreased fluid volume by increasing the heart rate (tachycardia) to maintain adequate circulation. Bradycardia (Choice A) is not expected in hypovolemia since the heart rate typically increases to compensate for the reduced blood volume. Increased blood pressure (Choice C) is unlikely in hypovolemia as the decreased fluid volume leads to decreased pressure. A bounding pulse (Choice D) is more associated with conditions like hyperthyroidism or fever, not specifically with hypovolemia.

5. Which electrolyte imbalance should be closely monitored in patients on furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss in the body, resulting in hypokalemia. Monitoring potassium levels is crucial in patients on furosemide to prevent complications such as cardiac arrhythmias and muscle weakness. Choice B, hyponatremia, is not typically associated with furosemide use. Hyperkalemia (choice C) and hypercalcemia (choice D) are not commonly linked to furosemide therapy; therefore, they are incorrect choices.
