The nurse instructs the laboring client to begin pushing with her contractions

A. help the fetal head descend faster: Accelerating fetal descent is contraindicated during a cord prolapse as it increases the mechanical pressure on the umbilical vessels. Rapid descent would worsen fetal hypoxia by further occluding the lifeline between the placenta and fetus. The primary clinical goal is to halt descent until delivery.

B. prevent head compression during contractions: While contractions cause cranial pressure, the immediate life-threatening risk is the occlusion of the umbilical cord. Fetal head compression is a normal physiological occurrence, whereas cord compression leads to acute asphyxia. Interventions must prioritize the restoration of umbilical blood flow over cranial protection.

C. facilitate rapid dilation of the cervix: Increasing the rate of cervical dilation does not resolve the emergency of a prolapsed cord. A fully dilated cervix may allow for faster delivery, but the mechanical obstruction of the cord remains the priority. The knee-chest position is a resuscitative maneuver, not a method to enhance labor.

D. relieve compression of the cord through gravity and manipulation: Placing the client in a knee-chest position uses gravity to shift the fetus away from the pelvic inlet. Combined with manual elevation of the fetal head, this reduces pressure on the prolapsed cord. This maintains umbilical perfusion until an emergency cesarean section.

A. increase her protein: While a balanced diet is essential for gestational health, increasing protein intake does not address the underlying carbohydrate intolerance suggested by an elevated screening result. This intervention fails to provide the diagnostic clarity required for a definitive metabolic assessment. It is a nutritional adjustment rather than a clinical diagnostic step.

B. schedule a repeat one-hour test: A single elevated 1 hour 50g glucose challenge test provides sufficient screening evidence to warrant more definitive diagnostic testing. Repeating the same screening procedure is not standard protocol and delays the identification of gestational diabetes mellitus. The clinical pathway mandates a more rigorous, multi-hour diagnostic evaluation.

C. return for a fasting three-hour glucose tolerance test: A result of 150 mg/dl exceeds the standard 130 to 140 mg/dl threshold, necessitating a 100g 3 hour diagnostic test. This gold-standard procedure involves fasting and multiple blood draws to confirm or rule out gestational diabetes. It evaluates the body's ability to maintain glucose homeostasis over an extended period.

D. restrict her carbohydrate intake: Implementing dietary restrictions before a formal diagnosis is premature and may mask the results of subsequent diagnostic testing. Patients must maintain a normal carbohydrate load prior to a 3 hour glucose tolerance test to ensure accurate metabolic data. Therapeutic interventions are only initiated once a pathological state is confirmed.
