A 3-year-old client was successfully toilet trained prior to admission to the hospital for injuries sustained from a fall. The client's parents are very concerned that the child has regressed in toileting behaviors. Which information should the nurse provide to the parents?

A potty chair should be brought from home to maintain the current level of toileting skills.

Children usually resume their toileting behaviors when they leave the hospital.

Diapering will be provided since hospitalization is stressful to preschoolers.

A retraining program will need to be initiated when the child returns home.
