A nurse is reviewing the diagnostic findings for a preschool-age child who is suspected of having cystic fibrosis. Which of the following findings should the nurse identify as an indication of cystic fibrosis?
Sweat chloride content 85 mEq/L
72-hour stool analysis sample indicating hard, packed stools
Increased blood levels of fat-soluble vitamins
Chest x-ray negative for atelectasis
The Correct Answer is A
Choice A reason: A sweat chloride content of 85 mEq/L is indicative of cystic fibrosis, as normal values are below 30 mEq/L, and values above 60 mEq/L are diagnostic for cystic fibrosis.
Choice B reason: Hard, packed stools could be a sign of cystic fibrosis but are not as diagnostic as a sweat chloride test.
Choice C reason: Increased blood levels of fat-soluble vitamins are not typically associated with cystic fibrosis; patients often have deficiencies due to malabsorption.
Choice D reason: A chest x-ray negative for atelectasis does not indicate cystic fibrosis, as atelectasis can be present in many conditions.
