Which nursing intervention should be avoided in a child with diarrhea?

Taking a rectal temperature in a child with diarrhea is a nursing intervention that should be avoided because it can pose a risk for discomfort, trauma, or infection. Diarrhea often involves mucosal irritation and may predispose the child to rectal bleeding or further complications. Additionally, the rectal thermometer can introduce pathogens if the child is experiencing infectious diarrhea, exacerbating the condition or leading to more severe gastrointestinal symptoms.

In contrast, administering oral rehydration fluids is critical in managing diarrhea, especially in children, to prevent dehydration. Strict hand hygiene is essential to prevent the spread of infections, particularly in situations where diarrhea is caused by infectious agents. Additionally, turning the child every two hours is important for preventing pressure ulcers and ensuring comfort, especially if the child is experiencing prolonged periods of illness. Thus, taking a rectal temperature is the intervention that should be avoided in this situation.
