Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?

• A. Reposition the nasal cannula
• B. Lower the oxygen rate
• C. Encourage the client to cough and deep breathe
• D. Monitor the client's oxygen saturation level

Correct answer: B

Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 4 liters per minute via nasal cannula. The client becomes lethargic and confused. What action should the nurse take first?

• A. Decrease the oxygen flow rate
• B. Increase the oxygen flow rate
• C. Encourage the client to cough and deep breathe
• D. Monitor the client's oxygen saturation level

Correct answer: A

Rationale: In this scenario, the priority action for the nurse is to decrease the oxygen flow rate. Clients with COPD are sensitive to high levels of oxygen and can develop oxygen toxicity, leading to symptoms like lethargy and confusion. Decreasing the oxygen flow rate helps prevent this complication. Increasing the oxygen flow rate would worsen the client's condition. Encouraging coughing and deep breathing may not address the immediate issue of oxygen toxicity. While monitoring the client's oxygen saturation level is important, taking action to address the oxygen toxicity by decreasing the flow rate is the priority in this situation.

3. The nurse is planning care for a client who is receiving radiation therapy for breast cancer. Which intervention is most important for the nurse to include?

• A. Encourage the client to use sunscreen
• B. Apply lotion to the radiated area
• C. Keep the area dry and clean
• D. Encourage the client to exercise the arm

Correct answer: C

Rationale: Keeping the radiated area dry and clean is crucial to prevent skin irritation and infection. Radiation therapy can cause skin changes, making it susceptible to irritation and infection. Using sunscreen (Choice A) is not usually recommended on the radiated area as it can further irritate the skin. Applying lotion (Choice B) may not be suitable as it can trap moisture and cause skin breakdown. While encouraging exercise (Choice D) is important, keeping the area dry and clean takes precedence to prevent complications during radiation therapy.

4. A 7-year-old with cystic fibrosis (CF) has received instructions about home care. Which statement made by the child's mother indicates that further teaching is needed?

• A. My child should not have a cough at all times
• B. He needs to take pancreatic enzymes with meals and snacks
• C. He needs to use a bronchodilator every day
• D. His dietary intake needs to be high in protein and calories

Correct answer: A

Rationale: The correct answer is A. A cough at all times is not normal in a child with cystic fibrosis (CF) and indicates the need for further teaching on CF management. Choices B, C, and D are correct statements in managing CF: taking pancreatic enzymes with meals and snacks, using a bronchodilator daily, and maintaining a high-protein and high-calorie dietary intake are all appropriate for a child with CF.

5. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
