Question

Ordered: 0.03 mg over 8 hours
Available: 6 mcg/2 mL
What drip rate (mL/hr)?

Answer 1

To find the drip rate in mL/hr, convert the ordered dose from mg to mcg and set up a proportion using the available concentration. The drip rate is 10 mL/hr.

Step-by-step explanation:

To determine the drip rate in mL/hr, we need to convert both the ordered dose and the available concentration to the same units. Let's start with the ordered dose of 0.03 mg over 8 hours.

Since 1 mcg = 0.001 mg, we can convert the ordered dose to mcg by multiplying it by 1000: 0.03 mg * 1000 = 30 mcg.

Now, to find the drip rate in mL/hr, we need to know the total volume of the available concentration that will deliver 30 mcg. Using the available concentration of 6 mcg/2 mL, we can set up a proportion:

(6 mcg)/(2 mL) = (30 mcg)/(x)

Cross-multiplying gives us:

6 mcg * x = 2 mL * 30 mcg

Simplifying:

6x = 60 mL

Dividing both sides by 6:

x = 10 mL/hr

So, the drip rate is 10 mL/hr.
