Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. A client with deep vein thrombosis (DVT) is prescribed anticoagulants. What should the nurse monitor closely?

• A. Monitor for signs of bleeding, such as bruising.
• B. Monitor the client’s vital signs every hour.
• C. Monitor for pain in the affected limb.
• D. Assess for signs of pulmonary embolism, such as sudden shortness of breath.

Correct answer: D

Rationale: In clients with DVT, assessing for pulmonary embolism is crucial as a clot in the lungs can be life-threatening. Sudden shortness of breath or chest pain are key signs of a pulmonary embolism. While monitoring for signs of bleeding is important due to anticoagulant therapy, the immediate concern is detecting a potential pulmonary embolism. Monitoring vital signs and pain in the affected limb are relevant aspects of care but are not as urgent as assessing for pulmonary embolism in this scenario.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. The nurse is preparing an older adult for discharge following cataract extraction. What is the most important instruction?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Use direct lighting when reading for 6 weeks.
• D. Irrigate the conjunctiva with saline before applying ointment.

Correct answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

5. A client with a history of chronic kidney disease presents with increased swelling and shortness of breath. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Monitor the client's vital signs.
• D. Reposition the client to improve lung expansion.

Correct answer: B

Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.
