A nurse is evaluating the diagnostic study data of a patient with suspected cystic fibrosis (CF). Which of the following test results is associated with a diagnosis of cystic fibrosis?

  • A. Elevated sweat chloride concentration
  • B. Presence of protein in the urine
  • C. Positive phenylketonuria
  • D. Malignancy on lung biopsy
Correct Answer: A

Rationale: Gene mutations affect transport of chloride ions, leading to CF, which is characterized by thick, viscous secretions in the lungs, pancreas, liver, intestine, and reproductive tract as well as increased salt content in sweat gland secretions. Proteinuria, positive phenylketonuria, and malignancy are not diagnostic for CF.
