Final answer:
The client in labour has a cervix that is 5 centimetres dilated and 80% effaced. This means that the cervix is open to 5 centimetres in diameter, allowing for the passage of the baby. Effacement refers to the thinning of the cervix, and being 80% effaced means that the cervix has thinned out by 80%.
