The nurse is caring for a patient whose labor is being augmented with oxytocin.
The nurse recognizes that the oxytocin should be discontinued immediately if there is evidence of:

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.

Choice A rationale

An ultrasound for cervical length is a crucial diagnostic tool for assessing preterm labor. A shortened cervix, typically less than 2.5 cm, is a significant risk factor for preterm birth. Measuring the cervical length helps to determine the probability of progressing to true labor and guides subsequent interventions, such as cerclage or progesterone therapy.

Choice B rationale

Amniocentesis, the sampling of amniotic fluid, is primarily used for genetic testing, assessing fetal lung maturity, or diagnosing fetal infection. It is not a standard procedure for a patient with intermittent back pain and pelvic pressure at 28 weeks gestation, as it carries risks, including inducing labor and infection, and isn't the first-line diagnostic for this presentation.

Choice C rationale

A glucose tolerance test is a screening tool for gestational diabetes, typically performed between 24 and 28 weeks of gestation. While the patient is at this gestational age, the test is not directly related to the symptoms of back pain and pelvic pressure, which are more indicative of potential preterm labor. The test wouldn't be a priority in this specific context.

Choice D rationale

A fetal fibronectin (fFN) swab is a diagnostic test used to predict the likelihood of preterm birth. The presence of fFN, a protein that acts as a "glue" for the fetal sac, in cervical or vaginal secretions between 22 and 34 weeks gestation suggests an increased risk of preterm labor within the next one to two weeks. It is a key tool in managing preterm labor.

Choice E rationale

Encouraging fluids and rest is a common initial intervention for a patient with symptoms of preterm labor. Dehydration can sometimes trigger uterine contractions, so rehydration may help to stop them. Resting can also reduce uterine irritability. This non-pharmacological approach is often the first step before more aggressive treatments are considered. *.
