Nursing Elites

1. A nurse is caring 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 medication?

• A. Hemoglobin
• B. Platelet count
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

2. A client has a new ileostomy. Which of the following actions should the nurse take?

• A. Apply a skin barrier around the stoma.
• B. Empty the pouch when it is one-third full.
• C. Change the entire pouching system weekly.
• D. Cleanse the peristomal skin with alcohol.

Correct answer: C

Rationale: Changing the entire pouching system weekly is essential for maintaining skin integrity and preventing infection. Option A is incorrect as applying a skin barrier should be done during the pouch change, not separately. Option B is incorrect as ileostomy pouches should be emptied when they are one-third to one-half full to prevent leakage. Option D is incorrect because cleansing the peristomal skin with alcohol can be too harsh and may cause skin irritation.

3. A client scheduled for a thoracentesis requires assistance from a nurse. Which of the following actions should the nurse take?

• A. Assist the client to a prone position.
• B. Assist the client to a sitting position.
• C. Assist the client to a supine position.
• D. Assist the client to a lateral position.

Correct answer: B

Rationale: The correct answer is to assist the client to a sitting position. Placing the client in a sitting position helps facilitate easier access during the thoracentesis procedure by allowing gravity to assist in the removal of pleural fluid. Placing the client in a prone, supine, or lateral position would not provide the optimal positioning needed for a thoracentesis and could make the procedure more challenging or uncomfortable for the client.

4. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

5. A nurse is reviewing the medical record of a client who has acute kidney injury. Which of the following findings should the nurse report to the provider?

• A. Blood urea nitrogen (BUN) 15 mg/dL
• B. Urine output of 45 mL/hr
• C. Serum creatinine 3.5 mg/dL
• D. Calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C, 'Serum creatinine 3.5 mg/dL.' An elevated serum creatinine level indicates worsening kidney function and impaired renal clearance, which should be reported to the provider promptly. Choice A, 'Blood urea nitrogen (BUN) 15 mg/dL,' is within the normal range (7-20 mg/dL) and does not indicate acute kidney injury. Choice B, 'Urine output of 45 mL/hr,' is a low urine output but does not directly reflect kidney function decline. Choice D, 'Calcium 9 mg/dL,' is within the normal calcium range (8.5-10.5 mg/dL) and is not specifically indicative of acute kidney injury.
