A nurse is calculating a client's expected date of birth using Nägele's rule. The client tells the nurse that her last menstrual cycle started on November 27th. Which of the following dates is the client's expected date of birth?
September 3rd
September 20th
August 3rd
August 20th
The Correct Answer is A
Nägele's rule is a method used to estimate the expected date of delivery (EDD) for a pregnant woman. To use Nägele's rule, you start with the first day of the last menstrual period (LMP), add one year, subtract three months, and add seven days.
In this case:
LMP: November 27th
Add one year: November 27th of the following year
Subtract three months: August 27th
Add seven days: September 3rd
Therefore, according to Nägele's rule, the expected date of birth is September 3rd

Correct Answer is B
Explanation
A. Fetal lie being longitudinal is a normal and common fetal lie. It refers to the long axis of the fetus being parallel to the long axis of the mother.
B. Fetal position being persistent occiput posterior is a potential contributing cause.
Occiput posterior position (OP) can result in a more challenging and prolonged labor. This position, where the back of the baby's head is facing the mother's spine, is associated with increased back pain during labor.
C. Fetal attitude in general flexion is a favorable presentation for labor. Flexion allows for a smaller presenting diameter of the fetal head, facilitating descent through the birth canal.
D. Maternal pelvis being gynecoid is a favorable pelvic type for childbirth. The gynecoid pelvis is typically associated with easier labor and delivery.
Correct Answer is A
Explanation
A. The lowermost portion of the fetus is at the level of the ischial spines.
A. The lowermost portion of the fetus being at the level of the ischial spines is the correct interpretation of 0 station. In the station system, when the presenting part is at the level of the ischial spines, it is referred to as 0 station.
B. The largest fetal diameter passing through the pelvic outlet is generally represented by the complete passage of the fetus through the birth canal. This is more indicative of full cervical dilation (10 cm) rather than a specific station.
C. The posterior fontanel being palpable is not directly related to the concept of station. Fontanel palpation is more associated with determining fetal head position.
D. The fetal head being in the left occiput posterior position is related to fetal position, not station. The station describes the descent of the presenting part in relation to the ischial spines.
