50 grams of Magnesium sulfate is added to 1L of Lactated Ringers.
After giving an initial loading dose, the nurse is to infuse a maintenance dose of 2 gm/hr. What rate should the IV pump be set at?
10 mL/hr
20 mL/hr
30 mL/hr
40 mL/hr
The Correct Answer is D
Step 1 is to calculate the total amount of Magnesium sulfate in the solution. This is done by multiplying the amount of Magnesium sulfate per mL (which is 50g/L or 0.05g/mL) by the total volume of the solution (which is 1000mL). So, 0.05g/mL × 1000mL = 50g.
Step 2 is to calculate the rate of the IV pump. The maintenance dose is 2g/hr. So, if there are 50g in 1000mL, then 2g would be in (2g ÷ 50g) × 1000mL = 40mL. Therefore, the IV pump should be set at 40 mL/hr.

T (Term births): Delivered at 37 weeks or more → One (39 weeks) → T = 1
-
P (Preterm births): Delivered between 20–36 weeks → Twins (34 weeks, 1 pregnancy) + One at 35 weeks = 2 preterm pregnancies → P = 2
-
A (Abortions): Pregnancies ending before 20 weeks → 0
-
L (Living children): One from term birth, two from twins, and one from the other preterm = 4 living children → L = 4
Correct Answer: D. G4 T1 P2 A0 L4
Correct Answer is []
Explanation
The client is most likely experiencing Normal labor progression. The retraction of the fetal head against the maternal perineum, regular and progressing contractions, and full dilation of the cervix are all signs of normal labor progression.
Actions: The nurse should:
1. Encourage the client to push during contractions. This will help the baby move down the birth canal.
2. Monitor fetal heart rate. This is crucial to ensure the baby is not in distress.
Parameters: The nurse should monitor:
1. Frequency of contractions. This will help assess the progress of labor.
2. Fetal heart rate. Any abnormalities could indicate fetal distress, which would require immediate medical attention.
