Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A nurse is caring for a client in the second trimester of pregnancy and asks how to treat constipation. Which of the following statements by the nurse is appropriate?

• A. Decrease intake of vitamins and supplements to every other day
• B. Eat 15 g of fiber per day
• C. Consume 48 ounces of water each day
• D. Drink hot water with lemon juice each morning

Correct answer: D

Rationale: The correct answer is D. Drinking hot water with lemon juice in the morning is a natural and safe way to stimulate bowel movements and relieve constipation during pregnancy. Option A is incorrect as vitamins and supplements should not be decreased without consulting a healthcare provider, especially during pregnancy. Option B is inadequate as the recommended daily fiber intake during pregnancy is higher than 15g. Option C, while important for overall health, does not directly address constipation relief in pregnancy.

3. A nurse is planning a staff education program to review nursing interventions for patients who have kidney failure. What source should the nurse identify as the best source for obtaining evidence-based practice information?

• A. A recent peer-reviewed nursing research article
• B. A website for a nursing association
• C. A textbook published 5 years ago
• D. An expert opinion from a seasoned nurse

Correct answer: A

Rationale: The correct answer is A: A recent peer-reviewed nursing research article. Peer-reviewed research articles provide the most current and reliable evidence-based practice information for clinical care. Choice B, a website for a nursing association, may have valuable information but may not always guarantee the highest level of evidence. Choice C, a textbook published 5 years ago, may not reflect the most up-to-date practices and guidelines. Choice D, an expert opinion from a seasoned nurse, though valuable, is not as reliable as evidence derived from peer-reviewed research articles.

4. A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: The correct answer is A: Paradoxical pulse. Paradoxical pulse, which is a significant drop in systolic blood pressure during inspiration, indicates cardiac tamponade, a life-threatening complication of pericarditis. This finding requires immediate attention as it suggests potential compromised cardiac function. Choices B, C, and D are associated with pericarditis but do not indicate the same level of urgency as paradoxical pulse.

5. When educating a patient on the use of levodopa-carbidopa, which information should the nurse include?

• A. It is a cure for Parkinson's disease
• B. Monitor for dyskinesia
• C. It can be taken at any time
• D. It has no side effects

Correct answer: B

Rationale: The correct answer is B: 'Monitor for dyskinesia.' Levodopa-carbidopa can cause dyskinesia as a side effect, which is characterized by involuntary muscle movements. Patients need to be monitored for this adverse effect and instructed to report it to their healthcare provider. Choices A, C, and D are incorrect because levodopa-carbidopa is not a cure for Parkinson's disease, it should be taken at specific times for optimal effect, and it does have side effects, such as dyskinesia.
