Prior to an amniocentesis, what action by the client will need to be completed?

Choice A rationale:

While there is a risk of infection with any internal examination, it is not the primary reason for avoiding internal examinations in a client with placenta previa. The main concern is avoiding trauma to the placenta, which could result in significant bleeding.

Choice B rationale:

Although internal examinations may potentially stimulate uterine contractions, leading to preterm labor in some cases, this is not the primary reason for avoiding such examinations in clients with placenta previa. The primary concern remains the risk of bleeding due to placental disruption.

Choice C rationale:

The correct explanation for the nurse to provide is that an internal examination could result in profound bleeding. Placenta previa occurs when the placenta partially or completely covers the cervix, and any manipulation of the cervix or uterus through an internal examination could disrupt the placenta and cause severe bleeding, endangering both the mother and the baby.

Choice D rationale:

While there is a risk of rupturing the membranes during an internal examination, this is not the primary reason for avoiding such examinations in clients with placenta previa. The primary concern remains the risk of bleeding due to placental disruption.

Choice A rationale:

Administering oxytocin to the client via intravenous infusion is not appropriate when the nurse notes an umbilical cord protruding through the cervix. The priority is to relieve pressure on the cord to prevent fetal compromise, and administering oxytocin could worsen the situation.

Choice B rationale:

Applying oxygen at 2 L/min via nasal cannula is not the priority when an umbilical cord prolapse is detected. The focus should be on relieving pressure on the cord and changing the client's position to alleviate the compression.

Choice C rationale:

Preparing for insertion of an intrauterine pressure catheter is not appropriate when there is an umbilical cord prolapse. The immediate concern is the potential compromise of fetal blood flow, and addressing the cord prolapse takes precedence over any other interventions.

Choice D rationale:

Assisting the client into the knee-chest position is the correct action when an umbilical cord prolapse is observed during a vaginal exam. This position helps to alleviate pressure on the cord by moving the presenting part of the fetus off the cord and can prevent further fetal distress until more definitive interventions can be performed.
