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. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

3. A client on long-term corticosteroid therapy for rheumatoid arthritis presents with weakness and hypotension. What is the nurse's first action?

• A. Administer a PRN dose of corticosteroids.
• B. Place the client in a supine position.
• C. Encourage oral fluid intake.
• D. Review the client's recent medication history.

Correct answer: A

Rationale: Administering a PRN dose of corticosteroids is the correct first action when a client on long-term corticosteroid therapy presents with weakness and hypotension. In this scenario, the client is likely experiencing adrenal insufficiency due to prolonged corticosteroid use. Administering corticosteroids promptly can help correct this insufficiency and improve the client's symptoms. Placing the client in a supine position may be necessary for symptomatic hypotension, but addressing the root cause with corticosteroids is more crucial initially. Encouraging oral fluid intake is important for many conditions but is not the priority in this case. Reviewing the client's recent medication history can provide valuable information but is not the first action needed to address the client's current presentation.

4. A child newly diagnosed with sickle cell anemia (SCA) is being discharged from the hospital. Which information is most important for the nurse to provide the parents prior to discharge?

• A. Nutritional guidelines to support blood health
• B. Signs of infection to monitor for
• C. When to give pain medication
• D. Instructions about how much fluid the child should drink daily

Correct answer: D

Rationale: Proper hydration is crucial in managing sickle cell anemia (SCA) as it helps prevent sickling of red blood cells and reduces blood viscosity, which can lead to painful crises. Ensuring the child drinks enough fluids is essential to maintain adequate hydration levels and reduce the risk of complications. While nutritional guidelines and recognizing signs of infection are important aspects of care, maintaining proper hydration is the most immediate and critical factor in managing SCA and preventing crises.

5. A client with chronic obstructive pulmonary disease (COPD) is prescribed home oxygen therapy. What teaching should the nurse provide?

• A. Ensure that the client uses oxygen continuously at night.
• B. Instruct the client to avoid smoking and exposure to smoke.
• C. Teach the client how to clean and replace the oxygen tubing.
• D. Instruct the client to increase their fluid intake.

Correct answer: C

Rationale: The correct teaching for a client with COPD prescribed home oxygen therapy is to educate them on how to clean and replace the oxygen tubing. This is crucial to prevent infections and ensure the effectiveness of the oxygen delivery system. Option A is not necessary as oxygen therapy is usually prescribed as needed, not continuously at night. While smoking cessation and avoiding smoke exposure are important in COPD management, it is not directly related to home oxygen therapy. Increasing fluid intake is beneficial for some conditions but is not specifically related to home oxygen therapy for COPD.
