A nurse is administering betamethasone to a client who is at risk for pre-term labor at 30 weeks of gestation.

Which of the following outcomes should the nurse monitor for in the newborn?

This is because assessing fetal heart rate is the most important action to take first when a client has prelabor rupture of membranes (PROM) at 34 weeks of gestation and oligohydramnios.Fetal heart rate can indicate fetal well-being, distress, or infection.Oligohydramnios can increase the risk of umbilical cord compression and fetal hypoxia.

Choice A is wrong because administering IV fluids is not the first priority in this situation.IV fluids may be given to prevent dehydration, enhance uterine blood flow, or augment labor, but they are not as urgent as assessing fetal heart rate.

Choice B is wrong because obtaining a urine specimen is not the first priority in this situation.A urine specimen may be obtained to check for infection, proteinuria, or glucose levels, but they are not as urgent as assessing fetal heart rate.

Choice D is wrong because inserting an indwelling urinary catheter is not the first priority in this situation.An indwelling urinary catheter may be inserted to monitor fluid balance, prevent bladder distension, or reduce the risk of infection, but they are not as urgent as assessing fetal heart rate.

Normal ranges for fetal heart rate are 110 to 160 beats per minute.Oligohydramnios is defined as an amniotic fluid index of less than 5 cm.

Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm delivery to enhance fetal lung maturity.Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing when the baby breathes.This reduces the risk of respiratory distress syndrome and other complications in preterm infants.

Choice A is wrong because betamethasone does not reduce inflammation in the uterus.

Choice C is wrong because betamethasone does not prevent infection in the amniotic fluid.

Choice D is wrong because betamethasone does not increase blood flow to the placenta.

Normal ranges for gestational age are 37 to 42 weeks.

Preterm birth is defined as delivery before 37 weeks of gestation.Antenatal corticosteroids are recommended for women between 24 and 34 weeks of gestation who are at risk of preterm delivery within 7 days, and may be considered for women at 23 weeks of gestation or between 34 and 37 weeks of gestation depending on the clinical scenario.
