Practice Question

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?

Answer Choices:

A. A stool fat content analysis

B. Sweat chloride test ✓ Correct Answer

C. Pulmonary function tests

D. A sputum culture

Correct Answer:

Sweat chloride test

Rationale:

🧪The sweat chloride test is the gold standard diagnostic test used to confirm cystic fibrosis (CF).

🩺This test measures the amount of chloride in the child's sweat, which is typically elevated in individuals with CF due to a mutation in the CFTR gene that disrupts normal chloride transport.

📈A sweat chloride level of ≥60 mmol/L on two separate occasions is considered positive and confirms the diagnosis in the presence of clinical symptoms.

🔬Other tests like stool fat content analysis, sputum cultures, or pulmonary function tests may support the diagnosis or help monitor the disease but do not confirm it definitively.

📌Core Message

The sweat chloride test confirms cystic fibrosis by detecting abnormally high chloride levels in sweat, which reflect defective chloride transport.
