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 A
Explanation
Choice A rationale
This is the best response because it acknowledges the client’s question and refers her to a healthcare provider who can provide a comprehensive assessment and discuss the most appropriate contraceptive options for her specific situation.
Choice B rationale
While it’s important to understand a client’s sexual activity when discussing contraception, asking a minor about her sexual activity without a proper context or professional setting may be inappropriate and uncomfortable for the client.
Choice C rationale
This response may come off as judgmental or condescending. It’s crucial to provide a safe and non-judgmental environment when discussing sensitive topics like sexual health and contraception.
Choice D rationale
While barrier methods can be an effective form of contraception, it’s not appropriate to recommend a specific method without a thorough understanding of the client’s health history, lifestyle, and preferences.
Correct Answer is D
Explanation
A. In a cephalic (head-down) presentation, fetal heart tones are typically heard below the umbilicus.
B. A posterior position refers to the fetal back facing the mother's back, but it does not affect the heart tone location significantly.
C. A transverse lie would place the fetal heart tones at the lateral sides of the abdomen, not above the umbilicus.
D. In a frank breech position (buttocks presenting first), fetal heart tones are usually heard above the umbilicus, as the fetal head is positioned in the upper uterus.
