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. Before a client undergoes a Magnetic Resonance Imaging (MRI) scan with contrast, what should the nurse assess?

• A. If the client has any metal implants
• B. If the client has allergies to iodine or shellfish
• C. If the client has a history of claustrophobia
• D. If the client has ever had a similar procedure before

Correct answer: A

Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (Choice B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (Choice C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (Choice D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.

3. A client with diabetes mellitus is admitted with hyperglycemia. What is the priority nursing action?

• A. Administer insulin as prescribed
• B. Encourage fluid intake
• C. Monitor blood glucose levels frequently
• D. Assess for signs of hypoglycemia

Correct answer: A

Rationale: Administering insulin is the priority nursing action for a client admitted with hyperglycemia due to diabetes mellitus. Insulin helps lower blood glucose levels and prevent further complications associated with hyperglycemia. Encouraging fluid intake is important but not the priority as insulin administration takes precedence to address the immediate hyperglycemic state. Monitoring blood glucose levels frequently is essential but comes after administering insulin to ensure the treatment's effectiveness. Assessing for signs of hypoglycemia is incorrect as the client is admitted with hyperglycemia, which requires raising blood glucose levels, not lowering them further.

4. A postoperative client complains of sudden shortness of breath. What should the nurse do first?

• A. Administer oxygen
• B. Call the healthcare provider
• C. Prepare for chest x-ray
• D. Assess the client's lung sounds

Correct answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.

5. A client with a diagnosis of chronic heart failure is prescribed digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure
• B. Assess heart rate
• C. Monitor respiratory rate
• D. Measure oxygen saturation

Correct answer: B

Rationale: The correct answer is to assess the heart rate before administering digoxin. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.
