Nursing Elites

1. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

2. The healthcare provider is providing discharge instructions to a client with chronic heart failure. Which dietary recommendation is most appropriate?

• A. Increase fluid intake.
• B. Follow a low-sodium diet.
• C. Follow a high-protein diet.
• D. Increase sodium intake.

Correct answer: B

Rationale: The most appropriate dietary recommendation for a client with chronic heart failure is to follow a low-sodium diet. This helps manage the condition by reducing fluid retention and the workload on the heart. High fluid intake can lead to fluid overload and exacerbate heart failure symptoms. While protein is important for overall health, a high-protein diet is not specifically indicated for chronic heart failure. Increasing sodium intake is contraindicated in heart failure as it can worsen fluid retention and increase the workload on the heart.

3. A client with a history of pulmonary embolism is on anticoagulant therapy. What should the nurse monitor regularly?

• A. International Normalized Ratio (INR)
• B. Blood glucose levels
• C. Blood pressure
• D. Temperature

Correct answer: A

Rationale: Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.

4. The healthcare provider is caring for a client with a chest tube following a pneumothorax. Which assessment finding should be reported to the healthcare provider immediately?

• A. Continuous bubbling in the water seal chamber
• B. Absence of drainage in the collection chamber
• C. Tidaling in the water seal chamber
• D. Presence of subcutaneous emphysema around the insertion site

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber should be reported to the healthcare provider immediately. This finding may indicate an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Absence of drainage in the collection chamber (choice B) may signify that the chest tube is blocked, but it does not pose an immediate threat to the client's condition. Tidaling in the water seal chamber (choice C) is an expected finding and indicates proper functioning of the chest tube system. Presence of subcutaneous emphysema around the insertion site (choice D) suggests air leakage but is not as urgent as continuous bubbling in the water seal chamber.

5. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
