The order from a provider is: Start Pitocin at 5 milliunits/min to induce labor. The pharmacy provides you with a 500 mL bag with 15 units of Pitocin added. What is the rate that would be set on the infusion pump?
The Correct Answer is ["0.17"]
To calculate the infusion pump rate for Pitocin, you need to determine the concentration of Pitocin in the IV bag and then set the pump to deliver the desired dose rate. The pharmacy has added 15 units of Pitocin to a 500 mL bag. To start at 5 milliunits/min, you first convert the units of Pitocin to milliunits (15 units = 15,000 milliunits). Then, divide the total milliunits in the bag by the volume of the bag to find the concentration per mL (15,000 milliunits / 500 mL = 30 milliunits/mL). Now, to find the rate at which the pump should be set to deliver 5 milliunits/min, divide the desired dose rate by the concentration (5 milliunits/min / 30 milliunits/mL = 0.1667 mL/min). Therefore, the infusion pump should be set to approximately 0.17 mL/min.

Correct Answer is ["2525"]
Explanation
To calculate the total intake of the client, the nurse would add up all the fluids administered over the past 9 hours. The lactated Ringer's IV, which was given at a rate of 150 mL/hr for 9 hours, totals 1350 mL. The cefazolin was administered in 100 mL of 0.9% sodium chloride, and since it's an intermittent bolus, we count it once, adding 100 mL. The two units of packed RBCs add up to 525 mL (275 mL + 250 mL). The two IV bolus infusions of 0.9% sodium chloride are 500 mL in total (250 mL each). Lastly, the famotidine was given in 50 mL of 0.9% sodium chloride. Adding all these together, the nurse should record a total intake of 2525 mL for the client over the past 9 hours.
Correct Answer is ["0.6"]
Explanation
To calculate the maximum milliliters (mL) of Haloperidol a patient could receive in a 24- hour period, we must first determine the number of doses. Since the medication is to be administered every 4 hours, and there are 24 hours in a day, the patient could receive up to 6 doses in a day (24 ÷ 4 = 6). Each dose is 5 mg, and the medication's concentration is 50 mg/mL. Therefore, each dose would be 0.1 mL (5 mg ÷ 50 mg/mL = 0.1 mL). Over a 24-hour period, the maximum amount of Haloperidol the patient could receive is 0.6 mL (0.1 mL/dose × 6 doses).
