A patient is in preterm labor at 30 weeks gestation.
Her OB orders antenatal steroids.
The order is for the nurse to administer betamethasone IM and to repeat the dose after 2 hours.
Betamethasone is available as 4mg/mL in 10 mL vials.
How many mL will the nurse draw up in the syringe for each dose?
0.5 mL
1 mL
1.5 mL
3 mL
The Correct Answer is D
Step 1 is to calculate the volume of betamethasone to be drawn up for each dose. The order is to administer betamethasone IM and to repeat the dose after 2 hours. Betamethasone is available as 4mg/mL. Therefore, to administer a dose of 12mg, the nurse would need to draw up 12mg ÷ 4mg/mL = 3mL for each dose.

Correct Answer is ["0504."]
Explanation
To calculate the estimated date of birth (EDB) from the last menstrual period (LMP), follow these steps: Determine the first day of the last menstrual period. In this case, it’s July 27. Count back 3 calendar months from that date, which gives us April 27. Lastly, add 1 year and 7 days to that date. This gives us an EDB of May 4, 2024. So, the EDB in MMDD format is 0504.
Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale
Variable decelerations are not related to fetal head compression. Fetal head compression typically results in early decelerations, not variable ones.
Choice B rationale
Variable decelerations are indeed due to umbilical cord compression. They are quick decreases in fetal heart rate that vary with uterine contractions. This can be a sign that the baby’s blood flow is reduced if variable decelerations happen over and over.
Choice C rationale
Uteroplacental insufficiency typically results in late decelerations, not variable ones. Late decelerations are a sign of fetal hypoxia and are associated with uteroplacental insufficiency.
Choice D rationale
While certain medications can affect the fetal heart rate, variable decelerations are not typically a result of the administration of narcotic analgesics.
