Final answer:
The perinatal nurse can document the extent of cervical dilation, fetal presentation, presence of cervical effacement, status of the amniotic membranes, and strength of uterine contractions from a vaginal examination.
Step-by-step explanation:
From a vaginal examination, the perinatal nurse can document the following assessments:
- Extent of cervical dilation: This assessment measures how open the cervix is and indicates progress in labor. It is measured in centimeters.
- Fetal presentation: This refers to the position of the baby in the womb, such as head-down (vertex) or breech.
- Presence of cervical effacement: Effacement is the thinning and shortening of the cervix, which also indicates progress in labor. It is measured in percentage.
- Status of the amniotic membranes: This assessment determines whether the amniotic sac is intact or if there is a rupture, which can indicate the need for intervention.
- Strength of uterine contractions: The nurse can assess the frequency, duration, and intensity of contractions to monitor the progress of labor.
