A child who has a suspected diagnosis of cystic fibrosis.


Question 1 of 5

A nurse is caring for a child who has a suspected diagnosis of cystic fibrosis. Which of the following diagnostic tests will confirm the diagnosis?

Correct Answer: C

Rationale: The correct answer is C: Sweat chloride test. Cystic fibrosis is confirmed by elevated sweat chloride levels, as it is a hallmark of the disease. This test measures the amount of salt in the sweat, which is typically higher in individuals with cystic fibrosis due to defective chloride channels. A stool fat content analysis (
A) may help assess pancreatic insufficiency but does not confirm cystic fibrosis. Pulmonary function tests (
B) are useful in evaluating lung function but do not confirm the diagnosis. A sputum culture (
D) may show respiratory infections common in cystic fibrosis but does not confirm the disease.
