A patient in active labor is prescribed oxytocin 12 milliunits/min intravenously (IV). The IV bag contains 5 units of oxytocin in 500 mL of lactated Ringer’s solution.
How many mL/hour should the nurse set the infusion pump to? (Enter numerical value only) .
The Correct Answer is ["72"]
Step 1 is.. Determine oxytocin concentration in IV solution. 5 units ÷ 500 mL = 0.01 units/mL.
Step 2 is.. Convert to milliunits. 0.01 units/mL × 1000 = 10 milliunits/mL.
Step 3 is.. Calculate infusion rate. 12 milliunits/min ÷ 10 milliunits/mL = 1.2 mL/min.
Step 4 is.. Convert to mL/hour. 1.2 mL/min × 60 = 72 mL/hour.
Final Answer: 72

Correct Answer is B
Explanation
Choice A rationale
Preparing a vacuum is not the first action to take in this situation. A vacuum-assisted delivery might be considered in some cases, but it’s not the immediate action when the fetal head retracts against the perineum.
Choice B rationale
Applying suprapubic pressure is the correct action. This situation describes shoulder dystocia, where the baby’s shoulder gets stuck behind the mother’s pelvic bone during delivery. Suprapubic pressure can help dislodge the baby’s shoulder and allow the delivery to proceed.
Choice C rationale
Applying fundal pressure is not recommended in this situation. Fundal pressure could potentially worsen shoulder dystocia and is generally avoided.
Choice D rationale
Preparing forceps is not the immediate action to take. Forceps may be used in some delivery situations, but in the case of shoulder dystocia, other maneuvers are tried first.
