Pediatric Respiratory questions with rationale

How does the nurse interpret the laboratory analysis of a stool sample containing excessive amounts of azotorrhea and steatorrhea in a child with cystic fibrosis (CF)? The values indicate the child is 1. Not compliant with taking her vitamins. 2. Not compliant with taking her enzymes. 3. Eating too many foods high in fat. 4. Eating too many foods high in fiber. correct answer ANS 2 2. If the child were not taking enzymes, the result would be a large amount of undigested food, azotorrhea, and steatorrhea in the stool. Pancreatic ducts in CF patients become clogged with thick mucus that blocks the flow of digestive enzymes from the pancreas to the duodenum. Therefore, patients must take digestive enzymes with all meals and snacks to aid in absorption of nutrients. Often, teens are noncompliant with their medication regimen because they want to be like their peers. TEST-TAKING HINT: The test taker needs to understand the pathophysiology of CF and the impact it has on the gastrointestinal system. The test taker also must be familiar with the conditions azotorrhea and steatorrhea. Which would the nurse explain to parents about the inheritance of cystic fibrosis? 1. CF is an autosomal-dominant trait passed on from the child's mother. 2. CF is an autosomal-dominant trait passed on from the child's father. 3. The child of parents who are both carriers of the gene for CF has a 50% chance of acquiring CF. 4. The child of a mother who has CF and a father who is a carrier of the gene for CF has a 50% chance of acquiring CF. correct answer ANS 4
