Nursing Elites

1. What is the leading cause of morbidity and mortality in children with cystic fibrosis?

• A. Respiratory infections
• B. Malnutrition
• C. Diabetes
• D. Liver disease

Correct answer: A

Rationale: Respiratory infections are the leading cause of morbidity and mortality in children with cystic fibrosis. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which predisposes these children to recurrent respiratory infections. Malnutrition and diabetes are common comorbidities in cystic fibrosis but are not the leading causes of morbidity and mortality in affected children. Liver disease can occur in cystic fibrosis but is less common than respiratory complications.

2. 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.

3. What is the best initial intervention for a child experiencing moderate dehydration?

• A. Administer IV fluids
• B. Encourage oral rehydration
• C. Monitor vital signs
• D. Provide clear fluids

Correct answer: B

Rationale: The correct answer is B: Encourage oral rehydration. Oral rehydration is the first-line treatment for moderate dehydration in children. It helps restore fluid balance and electrolyte levels. Administering IV fluids (Choice A) is usually reserved for severe cases of dehydration where oral rehydration is not feasible or ineffective. Monitoring vital signs (Choice C) is important but should not replace the immediate need for rehydration. Providing clear fluids (Choice D) may not contain the necessary electrolytes required for effective rehydration.

4. A two-month-old infant who has gastroesophageal reflux is thriving without other complications. Which instruction should the nurse include in the teaching plan?

• A. Place the infant in the Trendelenburg position after feeding
• B. Thicken formula with rice cereal
• C. Give continuous nasogastric feedings
• D. Give larger, less frequent feeds

Correct answer: B

Rationale: The correct instruction for a two-month-old infant with gastroesophageal reflux who is thriving without complications is to thicken the formula with rice cereal. This can help reduce reflux by increasing the weight of the formula, making it less likely to be regurgitated. Placing the infant in the Trendelenburg position after feeding (Choice A) is not recommended as it can increase the risk of aspiration. Continuous nasogastric feedings (Choice C) are not typically indicated for uncomplicated reflux in infants. Giving larger, less frequent feeds (Choice D) can worsen reflux symptoms by overloading the stomach.

5. After a 7-year-old with acute diarrhea has been rehydrated with oral rehydration solutions, what type of diet should the nurse recommend following rehydration?

• A. Regular diet
• B. Fruit juices
• C. High carbohydrate diet
• D. BRAT diet (bananas, rice, apples, and toast or tea)

Correct answer: A

Rationale: After rehydration, a regular diet is generally recommended to ensure proper nutrition and recovery. A regular diet includes a balanced intake of all food groups and nutrients. Fruit juices may be too high in simple sugars and lack necessary nutrients, which can exacerbate diarrhea. While a high carbohydrate diet may be beneficial in some cases, a regular diet is more comprehensive. The BRAT diet, consisting of bananas, rice, apples, and toast or tea, was previously recommended for diarrhea, but it lacks adequate protein and fat, so a regular diet is now preferred for overall better nutrition and recovery.
