Final answer:
A nurse would expect to assess gastrointestinal symptoms such as bloating, cramps, nausea, and diarrhea in a child diagnosed with lactose intolerance. Tests like stool acidity and hydrogen breath tests may help confirm the diagnosis.
Step-by-step explanation:
A nurse admitting a child with a diagnosis of lactose intolerance would expect to assess symptoms that are typically associated with the condition. These symptoms can include bloating, cramps, nausea, and vomiting due to the lack of the enzyme lactase, which is necessary for the digestion of lactose found in milk and other dairy products. In cases where there is an inability to digest the lactose, a child may exhibit gastrointestinal distress such as diarrhea. It is important for the nurse to look for these signs and symptoms to confirm the lactose intolerance diagnosis.
For small infants who are suspected of having lactose intolerance, stool acidity might be tested, as other forms of testing can be too risky. In older children and adults, a hydrogen breath test might be conducted to assess the presence of undigested lactose. Additionally, an intestinal biopsy can be performed in highly specialized settings to measure lactase enzymes directly. Avoidance of lactose-containing foods and the use of lactase supplements or lactose-free milk are common management strategies.
