A nurse is caring for a school-age child who has diabetes mellitus. Which of the following findings should the nurse recognize as being consistent with hyperglycemia?

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. Capillary refill time of 3 seconds is within the normal range (less than 3 seconds) and does not indicate severe dehydration.

B. A sunken anterior fontanel is a significant sign of dehydration in infants and suggests severe dehydration.

C. While a weight loss of 5% can indicate dehydration, it may not necessarily represent severe dehydration. The extent of dehydration is better assessed by clinical signs such as fontanel status, skin turgor, and mucous membrane moisture.

D. Producing tears when crying is a reassuring sign and suggests adequate hydration, so it does not indicate severe dehydration.
