A client in latent phase of labor for the past 12 hours is requesting medication to help her rest.

Choice A. Accelerations are normal responses that indicate the fetus is healthy and active. Accelerations occur when the fetal heart rate increases in response to stimuli. •

Choice B. Late decelerations are nonreassuring patterns that indicate fetal hypoxia due to placental insufficiency. Late decelerations occur when the placental blood flow decreases due to uterine contractions during labor, causing the fetal heart rate to decrease. •

Choice C. Variable decelerations are nonreassuring patterns that indicate fetal hypoxia due to umbilical cord compression. Variable decelerations occur when the umbilical cord is trapped by the cervical opening or the fetal body part, twisted, or knotted, causing the fetal oxygen supply to be impaired and the fetal heart rate to drop sharply. •

Choice D. Early decelerations are reassuring patterns that indicate a neural reflex due to fetal head compression. Early decelerations occur when the fetal head is compressed by uterine contractions during labor, causing the parasympathetic nervous system to be stimulated and the heart rate to decrease. The correct answer is C. Variable decelerations are the most common pattern that indicates a problem with the umbilical cord and requires urgent intervention.

The question is about a client who has been in the latent phase of labor for 12 hours and wants some medication to help her rest. The nurse has to predict which medication the healthcare provider will prescribe. The choices are:. • A. Fentanyl: a synthetic opioid that is used for pain relief and sedation. It is fast-acting and potent, but can cause respiratory depression and nausea. • B. Meperidine: a synthetic opioid that is used for pain relief and sedation. It is less potent than fentanyl, but can cause seizures and serotonin syndrome. • C. Morphine: a natural opioid that is used for pain relief and sedation. It is less potent than fentanyl, but can cause respiratory depression and itching. • D. Secobarbital: a barbiturate that is used for sedation and anesthesia. It is not an opioid, but can cause respiratory depression and addiction.
