Final answer:
The expected finding in a client with lactose intolerance is flatulence. This occurs due to the fermentation of undigested lactose by bacteria in the large intestine, which also causes symptoms like abdominal cramps and bloating.
Step-by-step explanation:
Expected Finding in Lactose Intolerance
A nurse assessing a client suspected of having lactose intolerance would expect to find symptoms related to the malabsorption of lactose in the small intestine. The correct answer to the question is flatulence, which is a common symptom of lactose intolerance. Persons with this condition experience difficulty digesting lactose, leading to bacterial fermentation in the large intestine that produces gas. This process may also result in symptoms such as abdominal cramps, bloating, and diarrhea. However, the options of bloody stools, hyperemesis, and steatorrhea are not typical findings in lactose intolerance. Bloody stools may suggest infections or other gastrointestinal conditions while hyperemesis and steatorrhea are related to other digestive system disorders.
While a clinical diagnosis can often be made based on the presentation of these symptoms following lactose ingestion, definitive diagnosis may involve tests such as a hydrogen breath test or stool acidity measurement in infants. The management for lactose intolerance often includes dietary modification, such as the avoidance of lactose-containing foods or the use of lactase enzyme supplements.
