Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin (A1C)
• C. Urine output
• D. Serum ketone level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.

3. A client with heart failure is prescribed spironolactone. What is the nurse's priority intervention?

• A. Monitor the client's potassium levels closely.
• B. Assess for signs of hyperkalemia.
• C. Instruct the client to increase intake of potassium-rich foods.
• D. Increase the client’s fluid intake to prevent dehydration.

Correct answer: B

Rationale: The correct answer is B: Assess for signs of hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can cause hyperkalemia (high potassium levels). Therefore, the nurse's priority intervention should be to assess the client for signs of hyperkalemia, such as muscle weakness, fatigue, and potentially dangerous cardiac arrhythmias. Monitoring potassium levels closely (choice A) is important but assessing for signs of hyperkalemia takes precedence. Instructing the client to increase intake of potassium-rich foods (choice C) can exacerbate hyperkalemia in this case. Increasing the client’s fluid intake to prevent dehydration (choice D) is not directly related to the potential side effect of spironolactone.

4. A client with hypertension has been prescribed a calcium channel blocker. What should the nurse include in the client's teaching plan?

• A. Monitor heart rate regularly
• B. Avoid potassium-rich foods
• C. Increase fluid intake to avoid dehydration
• D. Take the medication with food

Correct answer: A

Rationale: Corrected Rationale: Calcium channel blockers can cause bradycardia, so it is important for the client to monitor their heart rate regularly. This helps detect any significant changes in heart rate that may require medical attention. Choice B is incorrect because there is no need to avoid potassium-rich foods with calcium channel blockers. Choice C is incorrect as increasing fluid intake is not specifically related to calcium channel blockers. Choice D is incorrect as calcium channel blockers are usually taken with or without food, depending on the specific medication, but not specifically on an empty stomach.

5. A client with multiple sclerosis is admitted with an acute exacerbation. What is the nurse's priority action?

• A. Monitor the client’s vital signs every hour.
• B. Assess for changes in the client’s muscle strength.
• C. Administer prescribed corticosteroids to reduce inflammation.
• D. Educate the client on managing fatigue and preventing relapses.

Correct answer: C

Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.
