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

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. What is the best age to introduce solid food into an infant’s diet?

Correct answer: B

Rationale: The introduction of solid foods is recommended at 4 to 6 months when the infant's digestive system is more developed and ready for solids.

3. The nurse is taking a health history of an adolescent. Which best describes how the chief complaint should be determined?

Correct answer: B

Rationale: Asking the adolescent directly about the reason for their visit encourages open communication and helps the nurse understand the primary concern from the patient's perspective.

4. The nurse is performing an assessment on a 10-week-old infant. The nurse understands that the developmental characteristic of hearing at this age is which?

Correct answer: C

Rationale: By 10 weeks, infants typically turn their heads to the side to locate the source of a sound made at ear level.

5. Which immunization is recommended for all newborns?

Correct answer: B

Rationale: The correct answer is B, the Hepatitis B vaccine. This vaccine is recommended for all newborns to prevent Hepatitis B infection, which can lead to chronic liver disease and liver cancer. The Hepatitis B vaccine is a crucial part of the routine immunization schedule for infants. Choices A, C, and D are incorrect because the recommended vaccine for newborns is specifically Hepatitis B, not Hepatitis A, Hepatitis C, or a combination of Hepatitis A, B, and C vaccines.
