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
The correct answer is: d. Right lower
Choice A: Right upper
Reason: The right upper quadrant is not typically where fetal heart tones are auscultated when the fetal back is on the right side and the head is in the lower part of the uterus. This area is more likely to be associated with the breech presentation if the fetus’s head is in the fundus.
Choice B: Left upper
Reason: The left upper quadrant would be considered if the fetal back was on the left side and the head was in the fundus. Since the nurse palpated the fetal back on the right side, this option is not applicable.
Choice C: Left lower
Reason: The left lower quadrant would be relevant if the fetal back was on the left side and the head was in the lower part of the uterus. Given the fetal back is on the right side, this is not the correct location.
Choice D: Right lower
Reason: The correct answer is the right lower quadrant. When the nurse palpates a round, firm, movable part (likely the head) in the fundus and a long, smooth surface (the back) on the right side, it indicates that the fetus is in a cephalic (head-down) position with its back on the right. Therefore, the fetal heart tones are best auscultated in the right lower quadrant.
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.
