53. The medication order is to mix 18 units of oxytocin in 650 mL normal saline. Start infusion at 20 mL/hr. Increase by 5 mL every 10 minutes until uterine contractions are 2 to 3 minutes apart. Do not exceed 45 miliunits/min. Maintain total IV fluid volume at 100 mL/hr.

How many miliunits/min will the patient receive in the first 10 minutes?

Answer ________________9.23

Explain to me how the answer comes up

Expert Solution

Given,
Ordered medication is 18 units of oxytocin in 650 ml normal saline i.e., 18 units/650ml
Infusion rate 20 ml/hr

Now, 650 ml saline contain 18 units
1 ml saline contain =18/650 units
20 ml saline contain =(18/650)×20 unit
=0.5538 unit
Now, 20 ml(0.5538unit) infuse in 1hr(60min)

So, 60 min time required to infuse 0.5538 unit
1 min time required to infuse =.5538/60 unit
=0.00923 unit
=9.23×10^-3 unit
=9.23 miliunits ( as 1 miliunit= 10^-3 unit)

Given infusion rate increase by 5ml every 10 minutes .
So, in first 10 min infusion rate will be 20ml/hr that is 9.23 miliunits/min
Therefore, 9.23 miliunits/min will the patient receive in the first 10 minutes
