What is the first action a nurse should take when planning care for a child with suspected helminth infection?

Obtaining a stool sample for ova and parasites is the first and most critical action when planning care for a child with a suspected helminth infection. This step is essential because it allows for the definitive diagnosis of the type of helminths present, guiding appropriate treatment options.

Collecting a stool sample ensures that the right laboratory tests can be performed to identify any eggs or larvae from the parasites, which is vital for distinguishing between different types of helminth infections. Until the results of the stool test are available, initiating treatment may not be appropriate, as different helminths may require different anthelmintic medications.

While performing a physical examination could provide valuable information about the child's health and symptoms, it does not directly confirm the presence of a helminth infection. Starting medication immediately is typically not advised without a confirmed diagnosis, as this could lead to unnecessary treatment and complications. Educating the family on prevention is important, but it is a subsequent step that should occur after establishing a diagnosis to ensure that the most relevant information and strategies can be communicated effectively.
