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 presents to the emergency room with an acute asthma attack. What is the nurse's priority intervention?

• A. Administer bronchodilators as prescribed.
• B. Administer oxygen at 2 liters per nasal cannula.
• C. Perform chest physiotherapy.
• D. Provide emotional support to reduce anxiety.

Correct answer: A

Rationale: The correct answer is to administer bronchodilators as prescribed. During an acute asthma attack, the priority is to open the airways quickly to help the client breathe more easily. Oxygen may be needed but bronchodilators take precedence as they directly target bronchoconstriction. Chest physiotherapy is not indicated in the acute phase of asthma and may exacerbate the condition. While emotional support is important, addressing the airway obstruction takes precedence in this situation.

3. The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?

• A. Frequent syncope
• B. Muscle rigidity
• C. Gait instability
• D. Fine motor tremors

Correct answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

4. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

5. In the critical care unit, which client should receive the most care hours by a registered nurse (RN)?

• A. A client with a newly inserted Foley catheter and Alzheimer's disease
• B. A 55-year-old with chronic kidney disease
• C. An 82-year-old client with a newly fractured femur and soft wrist restraints
• D. A 72-year-old with pneumonia and sepsis on antibiotics

Correct answer: C

Rationale: The client with a newly fractured femur and soft wrist restraints should receive the most care hours as they have physical limitations due to the fracture and mental limitations due to being restrained. This client requires continuous monitoring, support, and frequent assessments to prevent complications. Choices A, B, and D do not have the same level of physical and mental care needs as the client with the newly fractured femur and soft wrist restraints.
