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. This test is the gold standard for confirming a diagnosis of cystic fibrosis. In cystic fibrosis, there is a defect in the chloride channels in the sweat glands, leading to increased levels of chloride in the sweat. This test involves collecting sweat and measuring the chloride concentration. A positive result indicates the presence of cystic fibrosis.
Other choices are incorrect because:
A: A sputum culture is used to identify respiratory infections, not cystic fibrosis.
B: Pulmonary function tests assess lung function but do not confirm cystic fibrosis.
D: Stool fat content analysis is used to evaluate fat malabsorption, which can occur in cystic fibrosis, but it does not confirm the diagnosis.
