NCLEX PN Practice Questions Practice Question
An 8-year-old child is admitted to the hospital with pneumonia. The child has had frequent respiratory infections. A chloride sweat test is ordered. The nurse knows that the reason for this test is to rule out which condition?
Correct Answer: C
Rationale: The chloride sweat test is primarily used to diagnose cystic fibrosis (CF), a genetic disorder that affects the lungs and digestive system, leading to frequent respiratory infections and thick mucus production.
Option A, pernicious anemia, is unrelated to respiratory symptoms and focuses on vitamin B12 deficiency. Option B, diabetes insipidus, involves issues with water regulation in the body rather than respiratory infections. Option D, glomerulonephritis, pertains to kidney inflammation and does not connect to the symptoms presented. Thus, the chloride sweat test is specifically aimed at identifying cystic fibrosis in this scenario.
