Final answer:
To determine the drip rate, a proportion is used to find out that 24 mg corresponds to 1 mL. This volume is then divided by the prescribed time, resulting in a drip rate of 0.125 mL/hr.
Step-by-step explanation:
To calculate the drip rate, you need to first determine the volume to be infused over the prescribed time and then divide that volume by the number of hours. In this case, the student is ordered to receive 24 mg over 8 hours and the medication available is 96 mg in 4 mL.
First, let's find out how many mL of medication the student needs for 24 mg:
- 96 mg is present in 4 mL.
- To find the volume for 24 mg, we use the following proportion: (24 mg / 96 mg) * 4 mL.
- This calculates to 1 mL.
Since the total volume of 1 mL needs to be administered over 8 hours, we divide 1 mL by 8 hours:
- 1 mL / 8 hours = 0.125 mL/hr.
Therefore, the drip rate is 0.125 mL/hr.
