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. 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.

3. How should a healthcare provider monitor a patient with suspected deep vein thrombosis (DVT)?

• A. Monitor for leg swelling
• B. Encourage ambulation
• C. Check for redness
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct way for a healthcare provider to monitor a patient with suspected deep vein thrombosis (DVT) is to check for leg swelling. Leg swelling is a common symptom of DVT and monitoring for this sign is crucial for early detection and intervention. Encouraging ambulation may be beneficial for preventing DVT but is not the recommended method for monitoring an existing condition. Checking for redness may be useful in cases of superficial thrombophlebitis but is not specific to DVT. Monitoring oxygen saturation is more relevant for respiratory or cardiovascular conditions, not for DVT.

4. A client with gastroesophageal reflux disease (GERD) is being taught about lifestyle changes to manage the condition. Which of the following instructions should the nurse include?

• A. Avoid eating small, frequent meals.
• B. Sleep with the head of your bed elevated.
• C. Lie down after eating.
• D. Avoid drinking fluids with meals.

Correct answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus. Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.

5. Which lab value is critical for patients on warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.
