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.

What dietary modification is recommended for a child with cystic fibrosis?
- A. High carbohydrate
- B. Low protein
- C. High calorie
- D. Low fat
Correct Answer: C
Rationale: A high-calorie diet is recommended for children with cystic fibrosis due to their increased energy needs and malabsorption issues. Cystic fibrosis affects the pancreas, leading to poor digestion and absorption of nutrients, particularly fats, which requires dietary adjustments to maintain adequate nutrition. High carbohydrate (Choice A) is not the primary focus; the emphasis is on overall calorie intake. Low protein (Choice B) is not recommended as protein intake is essential for growth and development. Low fat (Choice D) is not the best option as fat-soluble vitamin absorption is already compromised in cystic fibrosis, hence fat restriction is not a priority.
What is the recommended method to assess hydration status in infants?
- A. Capillary refill time
- B. Skin turgor
- C. Urine output
- D. Mucous membranes
Correct Answer: C
Rationale: The correct answer is C: Urine output. Assessing urine output is a recommended method to determine hydration status in infants. Adequate urine output indicates good hydration, while decreased urine output may suggest dehydration. Capillary refill time (Choice A) is more indicative of circulatory status rather than hydration. Skin turgor (Choice B) is a useful assessment in adults but can be less reliable in infants. Checking mucous membranes (Choice D) can provide some information on hydration, but it is not as reliable as assessing urine output in infants.
A child with acute gastrointestinal bleeding is admitted to the hospital. The nurse observes which sign or symptom as an early manifestation of shock?
- A. Restlessness
- B. Rapid capillary refill
- C. Increased temperature
- D. Increased blood pressure
Correct Answer: A
Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.
What is the priority nursing intervention for a child with epiglottitis?
- A. Administer antibiotics
- B. Maintain airway patency
- C. Provide hydration
- D. Monitor vital signs
Correct Answer: B
Rationale: The correct answer is B: Maintain airway patency. When dealing with a child with epiglottitis, the priority nursing intervention is to ensure airway patency to prevent airway obstruction, which can lead to respiratory distress or failure. Administering antibiotics (choice A) is important to treat the infection, but airway management takes precedence. Providing hydration (choice C) and monitoring vital signs (choice D) are essential aspects of care but are secondary to securing the airway in a child with epiglottitis.
Melena, the passage of black, tarry stools, suggests bleeding from which source?
- A. The perianal or rectal area
- B. The upper gastrointestinal (GI) tract
- C. The lower GI tract
- D. Hemorrhoids or anal fissures
Correct Answer: B
Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.
