Final answer:
The parent should offer the child bananas, rice, applesauce, and toast for the next 48 hours.
Step-by-step explanation:
The correct statement by the parent indicating an understanding of the teaching is C) I will offer my child bananas, rice, applesauce, and toast for the next 48 hours.
This approach is in line with the recommended diet for a child with diarrhea. These foods are part of the BRAT diet (Bananas, Rice, Applesauce, Toast), which can help to bind the stool and provide easily digestible nutrients.
It is important to note that the parent should continue to monitor the child's condition and consult with a healthcare professional if there are any concerns or worsening symptoms.
