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. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has been experiencing increasing shortness of breath. Which finding requires immediate intervention?

• A. A respiratory rate of 26 breaths per minute
• B. Use of accessory muscles for breathing
• C. Barrel chest appearance
• D. A pulse oximetry reading of 88%

Correct answer: D

Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to improve oxygenation. Hypoxemia can lead to serious complications if not addressed promptly. While a respiratory rate of 26 breaths per minute and the use of accessory muscles for breathing are concerning in COPD, they do not indicate an immediate life-threatening situation. Similarly, a barrel chest appearance is a common finding in COPD and does not require urgent intervention compared to the critical need to address hypoxemia.

3. Which information is a priority for the RN to reinforce to an older client after intravenous pyelography?

• A. Eat a light diet for the remainder of the day
• B. Rest for the next 24 hours as the preparation and the test are tiring
• C. Drink at least 1 8-ounce glass of fluid every waking hour for the next 2 days
• D. Measure the urine output for the next day and promptly notify the healthcare provider if it decreases

Correct answer: D

Rationale: After intravenous pyelography, it is crucial for the client to measure urine output in the next day to monitor for any potential complications, such as kidney issues. Promptly notifying the healthcare provider in case of decreased urine output is essential for timely intervention. While rest and hydration are important post-procedure, monitoring urine output takes precedence due to its direct correlation with potential complications.

4. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

5. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.
