B) Correct. It's important to administer all prescribed medications as directed to manage the condition effectively.

C) Incorrect. While infection control is important, it is not necessary for the child to avoid close contact with other children. Common-sense hygiene measures should be followed.

D) Correct. Regular follow-up appointments with the CF care team are crucial to monitor the child's health and adjust the treatment plan as needed.

A. To control blood sugar levels B. To improve lung function C. To aid in the digestion of fats and nutrients D. To increase mucus production in the airways

Correct Answer is C

Explanation

A) Incorrect. PERT is not primarily used to control blood sugar levels; it is used to improve nutrient absorption.

B) Incorrect. While CF management aims to improve lung function, PERT is specifically used to address pancreatic insufficiency and digestive issues.

C) Correct. The primary purpose of PERT in CF management is to replace the missing digestive enzymes and aid in the digestion of fats and nutrients.

D) Incorrect. PERT does not increase mucus production in the airways; it is focused on the digestive system.
