A client who is primiparous at 40 weeks of gestation calls the labor and delivery unit to ask about coming in to be evaluated for labor. The client reports having contractions every 6 to 8 min, which feels slightly painful. Which of the following questions should the nurse ask the client next?

A) "Have you had any health concerns during your pregnancy?"
While it's important to assess the client's overall health and pregnancy history, this question doesn't directly address the current concern of possible labor and does not immediately help assess the client's status for labor evaluation. The focus should be on signs of labor or complications at this point.

B) "Do you have a support person present?"
Although this is a helpful question to ask in preparation for labor, it doesn't provide the necessary information needed to assess whether the client is in labor. The priority at this stage is determining if the client is in labor or experiencing any complications, such as rupture of membranes.

C) "Have you noticed any fluid leaking from your vagina?"
This is the most important question to ask next. If the client has ruptured membranes (i.e., water breaking), it is important to assess the timing and nature of the fluid leakage, as it would indicate the need for immediate evaluation at the hospital. Rupture of membranes requires monitoring for infection and should prompt the client to come in for assessment regardless of the frequency or intensity of contractions.
D) "When was your last prenatal visit?"
While it is helpful to know when the client had their last prenatal visit, this question does not directly address the issue of possible labor. The priority is to determine if the client is in labor, whether their membranes have ruptured, or if there are any other complications such as bleeding or abnormal fetal movement. The question about fluid leakage is more immediate and relevant to their current condition.

A) Flexion:
Flexion is a movement where the fetal head bends forward during labor, which allows the smallest diameter of the head to pass through the birth canal. It is an important part of the labor process but does not refer to the initial descent of the fetus into the pelvis. Flexion typically occurs once the fetus begins to descend into the pelvis.

B) Engagement:
Engagement refers to the initial descent of the fetal head into the pelvis and the passage of the largest part of the fetal head (the biparietal diameter) into the maternal pelvis. This occurs when the fetal head reaches zero station at the level of the ischial spines and is the first cardinal movement of labor. It marks the point at which the presenting part of the fetus enters the pelvic inlet and begins the process of descent.

C) Extension:
Extension is the movement of the fetal head as it exits the birth canal after engagement and descent. The head moves from a flexed position (chin to chest) to an extended position (chin moving away from the chest) as it passes through the birth canal. This movement occurs after engagement and is a part of the expulsion phase, not the initial descent.

D) Expulsion:
Expulsion is the final phase of labor, which occurs after the fetal head has been delivered. It involves the delivery of the rest of the body (shoulders, torso, and legs) following the birth of the head. This is the final cardinal movement, which takes place after engagement, descent, flexion, internal rotation, extension, and external rotation.
