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.

Explanation
Choice A rationale
Missing a menstrual cycle and reporting vaginal spotting could indicate early pregnancy or other non-emergency conditions. While this client should be evaluated, it is not the highest priority.
Choice B rationale
A client at 28 weeks of gestation reporting painless vaginal bleeding could be experiencing placenta previa or placental abruption, both of which are obstetric emergencies. This client should be prioritized for immediate evaluation.
Choice C rationale
A client at 38 weeks of gestation reporting symptoms of a cough and fever may have an upper respiratory infection. While this should be evaluated, it is not the highest priority unless the client is in distress.
Choice D rationale
Nausea and vomiting are common in early pregnancy. A client at 14 weeks of gestation reporting these symptoms would need evaluation, but it is not the highest priority.
Correct Answer is C
Explanation
Choice A rationale
Assessing deep tendon reflexes every hour is a common practice in managing severe preeclampsia. Hyperreflexia can be a sign of worsening pre-eclampsia.
Choice B rationale
Continuous fetal monitoring is typically recommended for patients with severe pre-eclampsia. This allows for early detection of fetal distress.
Choice C rationale
Ambulating twice daily may not be appropriate for a patient with severe pre-eclampsia at 35 weeks of gestation. Bed rest is often recommended to help lower blood pressure and reduce the risk of complications.
