What action should a CNA take if they notice a resident passing liquid stools?

Notifying the charge nurse is the appropriate action when a CNA observes a resident passing liquid stools. This situation can indicate various medical conditions, such as an infection, gastrointestinal issues, or a reaction to medication, and requires a healthcare professional's assessment. The charge nurse has the training and authority to evaluate the situation further, determine the next steps, and decide on any necessary interventions or treatments.

Other options, such as administering medication or changing the resident's diet immediately, should only be done under the direction of a licensed nurse, as they can access the resident’s full medical history and assess any potential contraindications. Ignoring the situation could lead to complications for the resident, so it's crucial to communicate any significant changes in a resident's condition promptly.
