Nursing Elites

1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. What do the clinical manifestations of minimal change nephrotic syndrome include?

• A. Hematuria, bacteriuria, and weight gain
• B. Gross hematuria, albuminuria, and fever
• C. Hypertension, weight loss, and proteinuria
• D. Massive proteinuria, hypoalbuminemia, and edema

Correct answer: D

Rationale: Minimal change nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema due to the loss of protein in the urine. Hematuria, bacteriuria, and weight loss are not typical features of this condition.

3. The nurse is caring for an infant who had surgical repair of a tracheoesophageal fistula 24 hours ago. Gastrostomy feedings have not been started. What do nursing actions related to the gastrostomy tube include?

• A. Keep the tube clamped.
• B. Suction the tube as needed.
• C. Leave the tube open to gravity drainage.
• D. Secure the tube with tape.

Correct answer: C

Rationale: Leaving the gastrostomy tube open to gravity drainage prevents the accumulation of air and fluids, reducing the risk of complications such as vomiting or aspiration in the immediate postoperative period. Keeping the tube clamped or suctioning it can lead to pressure buildup, increasing the risk of complications. Securing the tube with tape is important but not the primary action related to the gastrostomy tube in this case.

4. Which medication should the nurse expect to administer to a child with an acute sickle cell pain crisis?

• A. Meperidine (Demerol)
• B. Morphine
• C. Acetaminophen (Tylenol)
• D. Ibuprofen (Motrin)

Correct answer: B

Rationale: In the management of acute sickle cell pain crisis in children, morphine is the preferred medication due to its effectiveness in providing pain relief. Meperidine (Demerol) is less commonly used in this scenario because of its potential for neurotoxicity with repeated doses. Acetaminophen (Tylenol) and Ibuprofen (Motrin) are not typically sufficient for managing the severe pain associated with sickle cell crises and are not the first-line treatment options.

5. What condition is the most common cause of acute renal failure in children?

• A. Pyelonephritis
• B. Tubular destruction
• C. Severe dehydration
• D. Upper tract obstruction

Correct answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.
