Maternal Child Health Nursing

A 25-year-old presented to the labor and delivery unit with complaints of uterine cramping and lower back pain. The client denied any vaginal bleeding and had a history of preterm birth at 32 weeks (about 7 and a half months) gestation with her last pregnancy. The baby from that pregnancy is three years old has no developmental issues. The client's gestational age is 30 weeks (about 7 months). She is O+, and all other lab values are normal. No evidence of sexually transmitted infections (STI's).

(Group Beta Strep is missing from the labs and most often is obtained at 35 - 37 weeks (about 8 and a half months) gestation. Without this information, it is often determined to treat the patient anyway, to protect a premature baby from the risk.)

What additional information should the nurse obtain from the client?
What nursing intervention is most appropriate in this situation?
What screening tests should be obtained to determine the risk for preterm labor?
If the client is in preterm labor, what medications would the nurse expect to be ordered, and what are the priorities for the nurse to assess post-administration? (Include dose, side effects and expected outcomes of the medication).

Full Answer Section

The most appropriate nursing intervention in this situation is to monitor the client closely for signs of preterm labor. This includes monitoring the frequency, intensity, and duration of the uterine contractions, as well as the amount and color of any vaginal discharge. The nurse should also monitor the client's vital signs, including her temperature, heart rate, respiratory rate, and blood pressure.

The following screening tests should be obtained to determine the risk for preterm labor:

  • Cervicometry: This test measures the length of the cervix. A short cervix is a risk factor for preterm labor.
  • Biophysical profile: This test evaluates the baby's heart rate, breathing movements, muscle tone, and body movements. A low biophysical profile score is a risk factor for preterm labor.
  • Fetal fibronectin test: This test detects a protein in the vagina that is produced by the cervix when it is starting to thin out. A positive fetal fibronectin test is a risk factor for preterm labor.

If the client is in preterm labor, the nurse would expect to be ordered the following medications:

  • Betamethasone: This medication helps to mature the baby's lungs. It is usually given in two doses, 24 hours apart.
  • Nifedipine: This medication relaxes the uterus and slows down contractions. It is usually given by mouth or by IV.
  • Magnesium sulfate: This medication helps to prevent seizures in preterm babies. It is usually given by IV.

The priorities for the nurse to assess post-administration of these medications include:

  • Betamethasone: Monitor the baby's heart rate and breathing.
  • Nifedipine: Monitor the blood pressure and heart rate.
  • Magnesium sulfate: Monitor the respiratory rate, urine output, and deep tendon reflexes.

The nurse should also educate the client about the signs and symptoms of preterm labor and what to do if she experiences them. The client should also be instructed to avoid strenuous activity and to get plenty of rest.

  • Is the pain sharp or dull?
  • Is the pain worse with activity or at rest?
  • Is there any vaginal discharge?
  • Is there any bleeding?
  • Has the client had any recent fevers, chills, or urinary tract infections?
  • Has the client had any recent trauma to the abdomen or pelvis?
  • Is the client taking any medications, including over-the-counter medications?
