A nurse is reviewing the laboratory results of a client who is at 29 weeks of gestation and has pre-term labor.

Which of the following results indicates an infection that can trigger pre-term labor?

Assess fetal heart rate using a Doppler device.

This is because low back pain and pelvic pressure at 36 weeks of gestation may indicate preterm labor, which can affect the fetal well-being.Therefore, the nurse should assess the fetal heart rate as a priority to determine if the fetus is in distress or not.

Choice A is wrong because tocolytic medication is used to stop uterine contractions, not to relieve low back pain and pelvic pressure.Choice B is wrong because resting in a side-lying position may help with blood circulation and reduce supine hypotensive syndrome, but it does not address the possible cause of low back pain and pelvic pressure.Choice D is wrong because assessing vaginal discharge for any change may indicate infection, rupture of membranes, or cervical dilation, but it is not as urgent as assessing fetal heart rate.

Some interventions for preventing and treating low back pain and pelvic pressure during pregnancy include exercise, water-based exercise, acupuncture, osteomanipulative therapy, craniosacral therapy, and pelvic support belts.

However, these interventions should be discussed with the health care provider before starting them.

This medication will help relax my uterus and stop contractions.

Magnesium sulfate is a tocolytic, a medication used to suppress uterine contractions and delay preterm delivery.The exact mechanism through which magnesium sulfate inhibits contractions is unknown, but researchers believe it likely works by lowering calcium levels in the uterine muscles.

Choice A is wrong because magnesium sulfate is not used to prevent seizures in case of preeclampsia.

Preeclampsia is a condition characterized by high blood pressure and protein in the urine during pregnancy.Magnesium sulfate may be used to treat seizures if they occur with eclampsia, which is a severe complication of preeclampsia.

Choice B is wrong because magnesium sulfate does not help mature the baby’s lungs in case of preterm birth.

Magnesium sulfate may have some neuroprotective effects for the baby, but it does not affect lung development.Steroids are usually given to pregnant women at risk of preterm delivery to help accelerate fetal lung maturation.

Choice D is wrong because magnesium sulfate does not lower blood pressure in case it gets too high.

Magnesium sulfate may have some vasodilatory effects, but it is not used as an antihypertensive agent.Other medications, such as hydralazine or labetalol, are used to treat high blood pressure during pregnancy.
