A nurse is caring for a client who is at 41 weeks of gestation and has a positive contraction stress test. For which of the following diagnostic tests should the nurse prepare the client?

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.

The correct answer is C. Place the client in a lateral position.

A. Elevating the client's legs is not the priority in this situation. Placing the client in a lateral position is more appropriate to improve blood flow and prevent supine hypotension.

B. Notifying the provider is an important action but not the immediate priority. Addressing the client's position and blood pressure is crucial before contacting the provider.

C. Placing the client in a lateral position is the priority nursing action.

The low blood pressure may be due to aortocaval compression (supine hypotension) caused by the weight of the uterus on the vena cava. Turning the client onto her side alleviates this compression and helps improve blood flow.

D. Monitoring vital signs every 5 minutes is important, but the immediate action should be to address the client's position and blood pressure. Continuous monitoring and further interventions can follow.
