Final answer:
During labor, a primigravida client who is receiving an epidural should be assisted into either a seated position, leaning forward with an arched back, or a side-lying fetal position. These positions help to widen the spaces between the vertebrae, making the administration of the epidural easier and safer.
Step-by-step explanation:
When assisting a primigravida client who is in labor and about to receive an epidural regional block, the nurse should help the client to assume a position that allows optimal access to the epidural space of the spine. This typically involves the client sitting on the edge of the bed with feet supported on a stool, leaning forward with arms resting on a table or pillows to arch the back, or lying on one side in a curled position, also known as the fetal position. Both positions aim to open the spaces between the vertebral bones, making it easier for the healthcare provider to administer the epidural anesthesia accurately and safely, which will help in relieving the discomfort of contractions. The epidural block is a common form of pain relief during the first stage of labor, where the cervix thins (effaces) and dilates, and this is particularly important as the cervix needs to dilate about 10 cm to allow the fetus to pass through during birth. When it comes to the position for receiving an epidural, the main goal is the comfort and safety of both the mother and the fetus, while ensuring maximum effectiveness of the medication.
