A nurse is preparing to administer nifedipine to a client who is in pre-term labor.

The nurse should withhold the medication and notify the provider if the client has which of the following conditions?

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 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.
