Nursing Elites

1. 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.

2. A nurse is caring for a client with a new colostomy. Which instruction should the nurse include in the client's teaching plan?

• A. Change the ostomy appliance daily
• B. Empty the ostomy pouch when it is one-third full
• C. Rinse the ostomy pouch with warm water
• D. Apply a skin barrier to the peristomal skin

Correct answer: B

Rationale: The correct instruction the nurse should include in the client's teaching plan is to empty the ostomy pouch when it is one-third full. This practice helps prevent leakage and skin irritation by maintaining an appropriate pouching system. Changing the ostomy appliance daily (Choice A) is not necessary unless leakage or other issues occur. Rinsing the ostomy pouch with warm water (Choice C) is not a recommended practice as it may cause damage to the pouch. Applying a skin barrier to the peristomal skin (Choice D) is important but not the most crucial instruction in this scenario.

3. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

4. A male client tells the nurse, 'I am so stressed because I am expected to achieve excellence in everything. My job, my marriage, and my children must be perfect!' Which coping response should the nurse recognize that the client is using?

• A. Repression
• B. Sublimation
• C. Rationalization
• D. Displacement

Correct answer: C

Rationale: The correct answer is C: Rationalization. Rationalization is a defense mechanism where the client justifies their stress and need for perfection by creating logical explanations or excuses. In this case, the client is rationalizing their stress by believing that everything in their life must be perfect. Repression (choice A) involves unconsciously blocking out thoughts or feelings. Sublimation (choice B) is redirecting unacceptable impulses into socially acceptable activities. Displacement (choice D) involves transferring emotions from one target to another.

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.
