A child who has suspected cystic fibrosis
Question 1 of 5
A nurse is reinforcing teaching about diagnostic tests with the parents of a child who has suspected cystic fibrosis. Which of the following diagnostic tests should the nurse include as the most definitive when diagnosing cystic fibrosis?
Correct Answer: B
Rationale: The correct answer is B: Sweat chloride test. This test is the most definitive diagnostic tool for cystic fibrosis as it measures the concentration of chloride in sweat, which is typically elevated in individuals with the condition. The other choices are not as specific to cystic fibrosis. A pulmonary function test (
A) evaluates lung function but does not specifically diagnose cystic fibrosis. Stool fat content analysis (
C) is used to assess fat malabsorption but does not confirm cystic fibrosis. Sputum culture (
D) is used to identify respiratory infections but is not specific to cystic fibrosis.
