A nurse is teaching the parents of a child who has cystic fibrosis about home care following discharge. Which of the following statements should the nurse include?

Rationale:

A. Periodic chest x-rays may be done to monitor lung function in cystic fibrosis, but it's not directly related to home care following discharge.

B. Tonsillectomy and adenoidectomy are not routine procedures for cystic fibrosis management unless there are specific indications beyond the disease itself.

C. Pancreatic enzyme replacement therapy with meals and snacks is essential for children with cystic fibrosis to aid in digestion and nutrient absorption due to pancreatic insufficiency, so this statement is crucial for home care.

D. Isoniazid is an antibiotic used to treat tuberculosis (TB), not cystic fibrosis, so this statement is incorrect and not relevant to cystic fibrosis home care.

Rationale:

A. Rolling over from back to abdomen typically occurs around 4 to 6 months of age.

While it may be slightly delayed, it is not usually concerning at 5 months.

B. Head lag at 5 months is abnormal and may indicate weakness or poor muscle tone, warranting further evaluation by the healthcare provider.

C. Not all infants are able to hold a bottle at 5 months, and this finding alone may not be concerning.

D. The grasp reflex typically diminishes by 3 to 4 months of age, so it may not be present at 5 months. While it's a developmental milestone, its absence alone may not warrant immediate concern at this age.
