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

Answer and Explanation

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.

Choice D rationale
Fetal breathing is one of the aspects evaluated during a biophysical profile. It is assessed to determine the respiratory function of the fetus.

Correct Answer is ["0.3"]

Explanation

Step 1 is to identify the concentration of the medication. From the search results, enoxaparin comes in pre-filled syringes with different concentrations, one of which is 30 mg/0.3 mL56.

Step 2 is to calculate the volume to be administered. Since the client is due to receive 30 mg of enoxaparin and the concentration is 30 mg/0.3 mL, the calculation is (30 mg ÷ 30 mg) × 0.3 mL. The final calculated answer is 0.3 mL.
