A nurse is caring for a client who is in labor and has a diagnosis of group B streptococcus B- hemolytic infection. Which of the following medications should the nurse plan to administer?
Ampicillin.
Azithromycin.
Ceftriaxone.
Acyclovir.
The Correct Answer is A
Choice A rationale:
The nurse should plan to administer Ampicillin to the client with a group B streptococcus (GBS) B-hemolytic infection. Ampicillin is the first-line antibiotic treatment for intrapartum prophylaxis in GBS-positive pregnant women. It helps prevent the transmission of the bacteria from the mother to the newborn, reducing the risk of early-onset GBS infection in the infant.
Choice B rationale:
Azithromycin is not the appropriate choice for treating GBS B-hemolytic infection during labor. While Azithromycin is effective against certain bacteria, it is not the recommended antibiotic for GBS prophylaxis in labor. Ampicillin or Penicillin is the preferred medication in this scenario.
Choice C rationale:
Ceftriaxone is not the appropriate medication for treating GBS B-hemolytic infection during labor. Ceftriaxone belongs to the cephalosporin class of antibiotics and is not the first-line treatment for GBS prophylaxis. Ampicillin or Penicillin is the preferred choice.
Choice D rationale:
Acyclovir is an antiviral medication and is not indicated for the treatment of GBS B-hemolytic infection. GBS is a bacterial infection, and antiviral medications like Acyclovir do not have an effect on bacteria.

Correct Answer is B
Explanation
Choice A rationale:
Hypotonicity, or decreased muscle tone, is not an expected finding in a newborn experiencing opioid withdrawals. Opioid withdrawal symptoms usually involve increased muscle tone and jitteriness.
Choice B rationale:
Moderate tremors of the extremities are an expected finding in a newborn experiencing opioid withdrawals. Neonates born to mothers who used opioids during pregnancy can exhibit tremors, irritability, and other withdrawal symptoms.
Choice C rationale:
An axillary temperature of 36.1°C (96.9°F) is within the normal range for a newborn's body temperature, so it is not directly related to opioid withdrawal and is not the expected finding in this situation.
Choice D rationale:
Excessive sleeping is not an expected finding in a newborn experiencing opioid withdrawals. Opioid withdrawal can lead to increased wakefulness and irritability in newborns.
Correct Answer is D
Explanation
Choice A reason:
Preparing for an amnioinfusion is not the first-line action. It may be considered if decelerations do not resolve with initial measures such as maternal repositioning.
Choice B reason:
Administering oxygen is a subsequent measure if initial interventions like repositioning do not improve the FHR. Oxygen is typically given at 8-10 L/min via a nonrebreather mask to increase fetal oxygenation.
Choice C reason:
Discontinuing oxytocin is important if the cause of decelerations is uterine hyperstimulation. However, repositioning the client should precede this action to quickly address potential umbilical cord compression.
Choice D reason:
This is the first action to take because it can quickly alleviate potential compression of the umbilical cord, which is often the cause of variable decelerations. It may be considered if decelerations do not resolve with initial measures such as maternal repositioning.
