Answer to Question 1

2,4,5
Rationale: The body's buffering system is more base than acid, due to the strong tendency toward acidity because acids are continually produced during metabolism

Answer to Question 2

3
Rationale: Children with cystic fibrosis need normal social interaction with other children, but must avoid those with contagious diseases in order to reduce the risk of infection, which can be challenging for parents. So the nurse must help them consider strategies to achieve this goal. It is unlikely a 4-year-old can make appropriate food choices, and the child with cystic fibrosis is challenged to meet adequate weight gain requirements, rarely facing a need to lose weight.
