Question

Eva's mother asks why the healthcare provider ordered a stool sample. Which of the following responses by the nurse demonstrates the most likely rationale for the stool sample given Eva's condition?

1) To check for any bacterial or parasitic infections in Eva's digestive system
2) To monitor Eva's liver function
3) To assess Eva's blood sugar levels
4) To evaluate Eva's kidney function

Answer 1

A stool sample is typically ordered to check for bacterial or parasitic infections, which is the most probable cause of Eva's symptoms. It helps in diagnosing conditions like gastroenteritis by detecting pathogens or toxins present in the digestive system.

Step-by-step explanation:

The most likely rationale for ordering a stool sample in Eva's condition is To check for any bacterial or parasitic infections in Eva's digestive system. This is because the presenting symptoms, as well as certain risk factors such as consumption of undercooked eggs, suggest a possible infectious etiology such as bacterial or viral gastroenteritis. A stool sample can reveal the presence of pathogens, blood, or even specific toxins that some bacteria produce, which are crucial in diagnosing and determining the appropriate treatment. Cases like Carli's where food poisoning is suspected due to undercooked eggs and Alex's, where traveler's diarrhea is the concern due to enterotoxigenic E. coli, are instances where analyzing stool samples is essential for correct diagnosis.
