A nurse is teaching the guardian of a child who is suspected of having cystic fibrosis and is scheduled for a sweat chloride test. Which of the following statements should the nurse include?

A. "Your child will need to receive sedation to minimize pain during the test.": Sedation is not necessary for a sweat chloride test. The test is noninvasive and painless, involving stimulation of sweat glands using a mild electric current. B. "It will take approximately 3 hours to complete the test.": The entire sweat chloride test usually takes about 1 hour or less, including preparation and collection time. It is a quick procedure, not lasting multiple hours. C. "Two separate samples will be collected to ensure accuracy of the test results.": Collecting two samples helps confirm the diagnosis, as elevated sweat chloride levels in both are indicative of cystic fibrosis. Repeat testing improves diagnostic reliability. D. "Your child should avoid eating and drinking 6 hours prior to the test.": Fasting is not required for a sweat chloride test. The child can eat and drink normally before the procedure, as it does not affect the results.
