Your patient is ordered to receive 20 units Pitocin in D5%W 500 mLs at 12 milliunits/minute.
What flow rate will you set the IV pump to deliver? Numeric values only.
The Correct Answer is ["mLs\/hr."]
Step 1 is to convert the order from milliunits/minute to units/hour. So, 12 milliunits/minute is equal to 0.72 units/hour. Step 2 is to calculate the total units in the IV bag, which is 20 units. Step 3 is to calculate the total volume of the IV bag, which is 500 mL. Step 4 is to calculate the flow rate. So, (0.72 units/hour ÷ 20 units) × 500 mL = 18 mL/hr. So, the correct flow rate to set on the IV pump is 18 mL/hr.

Correct Answer is D
Explanation
Choice A rationale:
Notifying the primary care provider is important but not the immediate next step. The nurse has other immediate responsibilities to ensure the safety of the mother and baby.
Choice B rationale:
A vaginal exam could introduce bacteria into the uterus and is not the immediate next step after rupture of membranes.
Choice C rationale:
Changing the linen saver pad is not the immediate next step. While it might be necessary for the comfort of the mother, it does not address the potential risks associated with rupture of membranes.
Choice D rationale:
Checking the fetal heart rate is the correct next step. This ensures that the baby is not in distress following the rupture of membranes.

Answer and explanation
Choice A rationale:
Butorphanol is an opioid agonist-antagonist. It would not be the first choice to treat opioid-induced respiratory depression because it can also cause respiratory depression.
Choice B rationale:
Promethazine is an antihistamine that has sedative effects and could potentially worsen respiratory depression.
Choice C rationale:
Fentanyl is a potent opioid and would likely exacerbate respiratory depression.
Choice D rationale:
Naloxone is an opioid antagonist used to reverse the effects of opioids such as respiratory depression.
