Nursing Elites

1. The nurse is caring for a client who is receiving chemotherapy. Which laboratory result indicates that the client is at risk for infection?

• A. Hemoglobin level of 12 g/dL.
• B. Platelet count of 150,000/mm3.
• C. White blood cell count of 2,000/mm3.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.

2. A 55-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. Imaging shows dilated intrahepatic bile ducts and a normal common bile duct. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: The presentation of fatigue, pruritus, and jaundice in a 55-year-old woman, along with elevated bilirubin and alkaline phosphatase levels, and imaging findings of dilated intrahepatic bile ducts and a normal common bile duct, are characteristic of primary biliary cirrhosis. Primary biliary cirrhosis is an autoimmune liver disease that typically affects middle-aged women, leading to progressive destruction of the intrahepatic bile ducts.

3. A 46-year-old man with a history of cirrhosis is brought in by his wife because he has been acting strangely. On examination, he is disoriented, ataxic, and has slurred speech. He is also hyperreflexic. His white blood cell count is normal. His hematocrit is 34%. Coagulation times are elevated. His ammonia level is normal. Which of the following statements regarding his management is correct?

• A. He should be treated with a low-protein diet and lactulose
• B. Lorazepam is not the drug of choice to control his behavior
• C. He should not be placed on gentamicin prophylactically to prevent the development of peritonitis
• D. If the patient complains of pain, acetaminophen should be avoided and nonsteroidal anti-inflammatory agents should be used

Correct answer: A

Rationale: This patient presents with symptoms consistent with hepatic encephalopathy. Despite having a normal ammonia level, he should be treated with lactulose and a low-protein diet as recommended for stage 2 hepatic encephalopathy. The normal ammonia level does not exclude the diagnosis, as it lacks sensitivity and specificity. Medications like lorazepam, gentamicin, and NSAIDs should be avoided due to their potential adverse effects in patients with liver disease. Acetaminophen should also be avoided in such patients.

4. The healthcare provider is caring for a client with a chest tube. Which assessment finding requires immediate intervention?

• A. Intermittent bubbling in the water seal chamber.
• B. Drainage of 75 ml in the first hour post-insertion.
• C. Crepitus around the insertion site.
• D. Fluctuation of the water level in the water seal chamber with respiration.

Correct answer: C

Rationale: Crepitus (subcutaneous emphysema) around the insertion site can indicate air leakage, requiring immediate intervention to prevent complications such as pneumothorax. This assessment finding suggests that there may be a break in the chest tube system, leading to air entering the pleural space. Prompt intervention is crucial to prevent respiratory compromise and further complications.

5. A client with a new diagnosis of myasthenia gravis is prescribed pyridostigmine (Mestinon). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to prevent gastrointestinal upset.
• B. Take the medication 30 minutes before meals.
• C. Avoid dairy products while taking this medication.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct instruction for a client with myasthenia gravis prescribed pyridostigmine (Mestinon) is to take the medication 30 minutes before meals. This timing is crucial as it helps improve muscle strength for eating and swallowing. By taking the medication before meals, the client can experience enhanced muscle function during mealtime, which is especially important for managing the symptoms of myasthenia gravis. Choices A, C, and D are incorrect. Taking the medication with food may decrease its effectiveness, avoiding dairy products is not necessary, and taking the medication at bedtime does not coincide with the optimal timing for enhancing muscle function during meals.
