Nursing Elites

1. 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.

2. A client with cirrhosis is taking lactulose (Cephulac). Which finding indicates that the lactulose is having the desired effect?

• A. Two to three soft bowel movements per day
• B. Increased serum ammonia levels
• C. Decreased white blood cell count
• D. Soft, formed stool twice a day

Correct answer: A

Rationale: The correct answer is A: 'Two to three soft bowel movements per day.' Lactulose is prescribed to produce soft, regular bowel movements to reduce ammonia levels in clients with cirrhosis. This helps in preventing hepatic encephalopathy. Option B is incorrect because increased serum ammonia levels would indicate that lactulose is not effectively reducing ammonia levels. Option C is incorrect because lactulose does not directly affect white blood cell counts. Option D is incorrect because soft, formed stools twice a day may not be frequent enough to effectively reduce ammonia levels in clients with cirrhosis.

3. A nurse is planning care for a client in the late stage of amyotrophic lateral sclerosis (ALS). Which nursing diagnosis has the highest priority?

• A. Impaired physical mobility
• B. Ineffective breathing pattern
• C. Impaired skin integrity
• D. Risk for infection

Correct answer: B

Rationale: Ineffective breathing pattern is the highest priority for a client in the late stage of ALS due to the significant risk of respiratory complications. As ALS progresses, the client may experience respiratory muscle weakness, leading to ineffective breathing patterns and potential respiratory failure. Addressing breathing difficulties promptly is crucial to ensure adequate oxygenation and prevent further complications. While impaired physical mobility, impaired skin integrity, and risk for infection are also important concerns in ALS care, they are secondary to addressing the client's breathing difficulties, which take precedence to maintain physiological stability and prevent life-threatening consequences.

4. A 9-year-old boy with tetralogy of Fallot is being discharged following a cardiac catheterization. Which discharge instruction should the nurse provide the parents?

• A. Do not allow the child to return to school for at least one month
• B. Notify the healthcare provider if there is any drainage at the catheterization site
• C. Monitor the child's temperature and report any elevation
• D. Observe for any changes in the child's color or energy level

Correct answer: B

Rationale: The correct answer is to notify the healthcare provider if there is any drainage at the catheterization site. Drainage at the site can be a sign of infection, which needs prompt evaluation and treatment. Choices A, C, and D are not as crucial as identifying and reporting any drainage, which is more directly related to potential complications post-cardiac catheterization.

5. The nurse is preparing a client for discharge who has a prescription for enoxaparin (Lovenox) self-administration. What information is most important for the nurse to provide the client about this medication?

• A. Self-administration techniques for subcutaneous injection
• B. Avoiding foods high in vitamin K
• C. Signs of bleeding to report to the healthcare provider
• D. Proper disposal of used syringes

Correct answer: A

Rationale: Teaching the client about self-administration techniques for subcutaneous injection is crucial for safe and effective use of enoxaparin. Option A is the correct answer as it directly addresses the client's need to know how to properly administer the medication. Options B, C, and D are important aspects of care but are not the most critical information needed for the client's self-administration of enoxaparin.
