Final answer:
The sitz bath after a vaginal delivery is primarily meant to assist in healing, reduce swelling, and provide comfort to the new mother.
Step-by-step explanation:
The purpose of a sitz bath after vaginal delivery is to promote healing, reduce edema and swelling, and provide comfort to the new mother. While the sitz bath can create a sensation of numbness due to the warm water, its primary function is not to numb the tissue. It is not typically used to stimulate a bowel movement. Therefore, the most accurate statement a client can make to demonstrate understanding of the purpose of a sitz bath is that it will assist in healing and provide comfort.
