Nursing Elites

1. 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: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.

2. How should fluid balance be assessed in a patient receiving diuretics?

• A. Monitor daily weight
• B. Monitor intake and output
• C. Check for edema
• D. Monitor blood pressure

Correct answer: A

Rationale: Corrected Rationale: Monitoring daily weight is the most accurate method to assess fluid balance in patients receiving diuretics. Changes in weight reflect changes in fluid balance, making it a sensitive indicator. Monitoring intake and output (choice B) is important but may not provide a complete picture of overall fluid balance. Checking for edema (choice C) is a late sign of fluid imbalance and may not be sensitive enough to detect subtle changes. Monitoring blood pressure (choice D) is relevant but may not directly reflect fluid balance as it can be influenced by various other factors.

3. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

4. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements indicates a need for further teaching?

• A. I will take warfarin every other day.
• B. I will eat more leafy green vegetables while taking warfarin.
• C. I will use a soft toothbrush while taking warfarin.
• D. I will have my INR checked regularly while taking warfarin.

Correct answer: B

Rationale: The correct answer is B. Eating more leafy green vegetables can increase vitamin K intake, which may reduce the effectiveness of warfarin. This can lead to fluctuations in the International Normalized Ratio (INR) levels, affecting the medication's efficacy. Choices A, C, and D are correct statements. Taking warfarin every other day, using a soft toothbrush to prevent gum bleeding, and having regular INR checks are all appropriate and important actions when taking warfarin.

5. A client with a new diagnosis of hypertension is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will check my blood pressure at least once a week.
• B. I will avoid eating foods high in potassium.
• C. I should exercise for 30 minutes at least 5 days a week.
• D. I will take my medication only when I feel dizzy.

Correct answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.
