A nurse is admitting a client who is at 39 weeks of gestation and in active labor. The client reports being positive for group B streptococcus (GBS) when screened at 36 weeks of gestation. Which of the following actions should the nurse expect to take?

 

A.

Prepare for a cesarean birth.

B.

Administer IV antibiotic prophylaxis.

C.

Obtain a vaginal culture.

D.

Administer metronidazole orally.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Cesarean birth is not necessarily required for GBS-positive clients as long as IV antibiotic prophylaxis is administered during labor to prevent transmission to the newborn.

 

Choice B rationale

IV antibiotic prophylaxis, typically with penicillin or ampicillin, is given to GBS-positive clients during labor to prevent neonatal GBS infection.

 

Choice C rationale

Obtaining a vaginal culture at 39 weeks of gestation is not necessary if the client was already screened and found positive for GBS at 36 weeks.

 

Choice D rationale

Metronidazole is used to treat bacterial vaginosis or trichomoniasis, not GBS infection; thus, it is not appropriate for this scenario. .

Correct Answer is A

Explanation

  1. Preterm Labor Risk: At 32 weeks of gestation, regular contractions every 5 minutes could indicate the onset of preterm labor. This is concerning because preterm labor can lead to preterm birth, which poses significant risks to the baby's health and development.

  2. Frequency and Intensity: These contractions are occurring frequently (every 5 minutes) and are described as stronger than usual Braxton Hicks contractions. This frequency and the strength of the contractions are unusual for Braxton Hicks, which are typically irregular and less intense.

  3. Effacement and Cervical Changes: Although the cervix is closed, it is 80% effaced. Effacement means the cervix is thinning, which, in combination with regular contractions, may indicate that the body is preparing for labor.

  4. Urinary Leakage: The client also reported urinary leakage earlier in the day, which could be a sign of ruptured membranes (water breaking). This, combined with regular contractions, increases the need for careful monitoring.

Correct Answer is ["B","C","D","E","F"]

Explanation

A. "I will inject this medication under your skin.": Tocolytic medications are typically administered orally, intravenously, or intramuscularly, not subcutaneously.

B. "You may experience a headache after receiving this medication."
Some tocolytic medications can cause headaches as a side effect.


C. "It is common for this medication to make you feel jittery."
Tocolytic medications, such as terbutaline, can cause nervousness or jitteriness.

D. "This medication should decrease your contractions."
The primary purpose of tocolytic medication is to decrease uterine contractions and delay preterm labor.


E. "I'll check your reflexes frequently while you are receiving this medication."
Some tocolytic medications, like magnesium sulfate, require monitoring of deep tendon reflexes to assess for potential toxicity.


F. "This medication can make your heart beat faster."
Tocolytic medications, such as terbutaline, can increase heart rate.


G. "This medication can increase your blood pressure.":

Some tocolytic medications, like magnesium sulfate, can actually lower blood pressure rather than increase it.
