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 hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

3. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?

• A. pH level of 7.45
• B. Serum calcium of 15 mg/dL
• C. Blood glucose of 450 mg/dL
• D. Sodium level of 120 mEq/L

Correct answer: C

Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.

4. An adolescent client with meningococcal meningitis is receiving a continuous IV infusion of penicillin G. How many mL/hour should the nurse program the infusion pump to deliver?

• A. 83
• B. 85
• C. 87
• D. 90

Correct answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

5. A client with a chest tube following a pneumothorax is complaining of increased shortness of breath. What is the nurse's first action?

• A. Check for kinks in the chest tube tubing.
• B. Assess the client's lung sounds.
• C. Elevate the head of the bed to 30 degrees.
• D. Prepare for chest tube replacement.

Correct answer: C

Rationale: The correct first action for a client with a chest tube experiencing increased shortness of breath is to elevate the head of the bed to 30 degrees. This position promotes lung expansion, improves oxygenation, and can help relieve shortness of breath. Checking for kinks in the chest tube tubing would be important but not the first action in this situation. Assessing the client's lung sounds is also important but not the initial priority. Preparing for chest tube replacement is not indicated based solely on the client's complaint of increased shortness of breath.
