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.

The parents of a newborn with an umbilical hernia ask about treatment options. The nurse's response should be based on which knowledge?
- A. Surgery is recommended as soon as possible.
- B. The defect usually resolves spontaneously by 3 to 5 years of age.
- C. Aggressive treatment is necessary to reduce its high mortality.
- D. Taping the abdomen to flatten the protrusion is not recommended.
Correct Answer: B
Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.
In children with Type 1 diabetes, what is a common early sign of hypoglycemia?
- A. Irritability
- B. Rapid heartbeat
- C. Confusion
- D. Sweating
Correct Answer: D
Rationale: Sweating is indeed one of the earliest signs of hypoglycemia in children with Type 1 diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can lead to sweating. While irritability, rapid heartbeat, and confusion can also be seen in hypoglycemia, sweating is particularly common as a quick indicator of low blood sugar levels in children with Type 1 diabetes.
An infant with short bowel syndrome is receiving total parenteral nutrition (TPN). The practitioner has added continuous enteral feedings through a gastrostomy tube. The nurse recognizes this as important for which reason?
- A. Wean the infant from TPN gradually
- B. Stimulate adaptation of the small intestine
- C. Provide additional nutrients that cannot be included in the TPN
- D. Offer parents encouragement that the child is close to discharge
Correct Answer: B
Rationale: Continuous enteral feedings help stimulate the small intestine's adaptation in short bowel syndrome, promoting better nutrient absorption and eventually reducing reliance on TPN. This approach is crucial for long-term management and improving the child's prognosis. Choice A is incorrect because weaning off TPN typically occurs gradually over time, not the next day. Choice C is incorrect because TPN can be adjusted to provide necessary nutrients, and enteral feedings are mainly used to stimulate intestinal function. Choice D is incorrect as the addition of enteral feedings does not necessarily indicate imminent discharge; it primarily focuses on enhancing intestinal adaptation and reducing reliance on TPN.
Which electrolyte imbalance is a common concern in children with severe diarrhea?
- A. Hypernatremia
- B. Hypokalemia
- C. Hypercalcemia
- D. Hypomagnesemia
Correct Answer: B
Rationale: Hypokalemia is the correct answer because it is a common concern in children with severe diarrhea. Diarrhea can lead to significant potassium loss, resulting in hypokalemia. Hypernatremia (Choice A) is less common in diarrhea as sodium concentration is usually diluted by the fluid loss. Hypercalcemia (Choice C) is not typically associated with severe diarrhea. Hypomagnesemia (Choice D) can occur but is not as common as hypokalemia in this scenario.
What is the typical presentation of pyloric stenosis in infants?
- A. Bilious vomiting
- B. Projectile vomiting
- C. Blood in stools
- D. Failure to thrive
Correct Answer: B
Rationale: The correct answer is B: Projectile vomiting. Pyloric stenosis in infants typically presents with projectile vomiting, which is forceful and projective in nature. This occurs due to the obstruction at the pylorus, leading to the stomach being unable to empty properly. Choices A, C, and D are incorrect. Bilious vomiting is more commonly associated with intestinal obstruction, blood in stools can occur in conditions such as necrotizing enterocolitis or allergic colitis, and failure to thrive is a nonspecific finding that can be seen in various pediatric conditions.
