In the event of shoulder dystocia, the nurse can assist by performing maneuvers to release the shoulder.

Choice A rationale

Rupture of the amniotic membranes is a natural part of labor progression and a common procedure for labor induction or augmentation. While it is an important event to note and monitor for potential complications like cord prolapse, it is not a direct contraindication for oxytocin administration unless other signs of fetal or maternal compromise are present.

Choice B rationale

A fetal heart rate of 140 beats per minute with accelerations is considered a normal, reassuring finding. The normal fetal heart rate range is 110-160 beats per minute. Accelerations indicate a healthy fetal response to stimulation and adequate oxygenation. Therefore, this finding would support the continuation of oxytocin, not its discontinuation.

Choice C rationale

Uterine hyperstimulation, defined as more than five contractions in 10 minutes, is a significant complication of oxytocin augmentation. This can lead to fetal distress due to reduced uteroplacental blood flow during contractions. The prolonged and frequent contractions can compromise oxygen delivery to the fetus, necessitating immediate discontinuation of the oxytocin infusion to prevent adverse outcomes.

Choice D rationale

A patient needing to void is a normal physiological need. While the nurse should ensure the patient voids regularly to prevent bladder distention, which can impede fetal descent, it is not an indication to discontinue the oxytocin infusion. This action can be managed without interrupting the medication administration.

Choice A rationale

Guided imagery is a cognitive-behavioral technique that uses mental focus on a peaceful scene or image to distract from pain. While it can be an effective pain management strategy for some women in labor, it is not specific to the physiological cause of back labor. Back labor pain is caused by the occiput of the fetus pressing against the maternal sacrum, which requires a physical, rather than a psychological, intervention to be most effective.

Choice B rationale

Progressive relaxation is a technique that involves tensing and relaxing different muscle groups throughout the body to relieve tension and promote comfort. Like guided imagery, it is a general pain management technique that can be useful for reducing overall labor discomfort. However, it does not directly address the specific cause of back labor, which is the physical pressure from the fetal head on the sacrum.

Choice C rationale

Slow, deep breathing is a common and effective technique for managing labor pain by promoting relaxation, increasing oxygenation, and distracting the patient. It helps the woman focus and cope with contractions. While beneficial for managing labor pain, it is not a targeted intervention for the intense, localized pressure and pain associated with back labor, which responds better to direct physical pressure.

Choice D rationale

Back labor pain is caused by the occiput of the fetus pressing against the maternal sacrum. Counterpressure is a physical intervention that involves applying firm, steady pressure with the heel of the hand or a fist against the sacral area during contractions. This direct pressure helps to displace the fetal head and counteract the pain, making it a highly effective and specific relief measure for back labor.
