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 caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?

• A. Disconnect the client from the ventilator and use a manual resuscitation bag
• B. Perform a quick assessment of the client's condition
• C. Call the respiratory therapist for help
• D. Press the alarm reset button on the ventilator

Correct answer: B

Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.

3. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

4. After receiving a report on an inpatient acute care unit, which client should the nurse assess first?

• A. Client with pneumonia who has a fever of 101.5°F
• B. Client who underwent knee surgery and needs dressing change
• C. Client with a bowel obstruction due to a volvulus experiencing abdominal rigidity
• D. Client with diabetes requesting insulin

Correct answer: C

Rationale: The correct answer is C. Abdominal rigidity in a client with a bowel obstruction could indicate peritonitis, a serious complication requiring immediate attention. Volvulus, a twisting of the intestine, can lead to bowel ischemia and necrosis. Clients with pneumonia (choice A) may need assessment and treatment for infection, but it is not as immediately life-threatening as a bowel obstruction. A client who underwent knee surgery (choice B) needing a dressing change can typically wait for assessment compared to a potential surgical emergency. Similarly, a client with diabetes requesting insulin (choice D) may require attention to maintain blood glucose levels, but it is not as urgent as a suspected bowel obstruction with possible peritonitis.

5. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?

• A. White blood cell count
• B. Hemoglobin
• C. Serum creatinine
• D. Culture for sensitive organisms

Correct answer: D

Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.
