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 required for a sweat chloride test because it is noninvasive and painless. The procedure involves stimulating sweat production with pilocarpine and collecting the sweat for analysis. B. "Two separate samples will be collected to ensure accuracy of the test results.": Collecting two sweat samples helps confirm the diagnosis of cystic fibrosis and minimizes the chance of error. Consistency across both samples increases the reliability of the test results. C. "Your child should avoid eating and drinking 6 hours prior to the test.": Fasting is not necessary for a sweat chloride test. The child can eat and drink normally before the procedure, as diet and fluid intake do not affect the accuracy of the test. D. "It will take approximately 3 hours to complete the test.": The sweat chloride test generally takes about 1 hour, including preparation and collection. It does not require prolonged testing time, making this statement inaccurate.
