A nurse is admitting a client who has a diagnosis of preterm labor. The nurse anticipates an order by the provider for which of the following medications?

Choice A reason: She is exhibiting hypertonic uterine dysfunction, because she has frequent and painful contractions that are ineffective in dilating the cervix. Hypertonic uterine dysfunction occurs when the uterus contracts too often and too forcefully, resulting in poor oxygenation and fetal distress. The woman may need tocolytic therapy, pain relief, and hydration.

Choice B reason: She is not experiencing a normal latent stage, because her contractions are too frequent and too painful for this phase of labor. The normal latent stage is characterized by irregular and mild contractions that gradually increase in frequency and intensity, and cervical dilation from 0 to 3 cm.

Choice C reason: She is not experiencing precipitous labor, because her labor is not progressing rapidly. Precipitous labor is defined as labor that lasts less than 3 hours from the onset of contractions to the delivery of the baby. It is associated with cervical dilation of more than 5 cm per hour.

Choice D reason: She is not exhibiting hypotonic uterine dysfunction, because her contractions are not weak or infrequent. Hypotonic uterine dysfunction occurs when the uterus contracts too weakly or too rarely, resulting in prolonged labor and increased risk of infection. The woman may need oxytocin augmentation, amniotomy, or cesarean section.

Choice A reason: Polyuria is not an expected finding in a client with severe preeclampsia, as it can indicate dehydration, diabetes, or renal impairment. A client with severe preeclampsia may have oliguria, which is a urine output of less than 500 mL in 24 hours, due to the decreased renal perfusion and function.

Choice B reason: Report of headache is an expected finding in a client with severe preeclampsia, as it can indicate increased intracranial pressure, cerebral edema, or vasospasm. A client with severe preeclampsia may also have other neurological symptoms, such as blurred vision, scotoma, photophobia, or hyperreflexia.

Choice C reason: Tachycardia is not an expected finding in a client with severe preeclampsia, as it can indicate dehydration, infection, anxiety, or fetal distress. A client with severe preeclampsia may have bradycardia, which is a heart rate of less than 60 beats per minute, due to the increased vagal tone and blood pressure.

Choice D reason: Absence of clonus is not an expected finding in a client with severe preeclampsia, as it can indicate normal or decreased neuromuscular irritability. A client with severe preeclampsia may have positive clonus, which is a rhythmic jerking of the foot when the ankle is dorsiflexed, due to the increased reflex excitability and hyperactivity.
