Questions: An order for Zofran 20 mg IVPB (IV piggyback) is ordered to be infused at a rate of 200 mL / hr. How long will it take (in minutes) to infuse this 50 mL bag?

Solution Steps

To determine how long it will take to infuse a 50 mL bag at a rate of 200 mL/hr, we need to divide the total volume of the bag by the infusion rate and then convert the time from hours to minutes.

To find the time it takes to infuse the 50 mL bag at a rate of 200 mL/hr, we use the formula: \[ \text{time}_{\text{hr}} = \frac{\text{volume}_{\text{mL}}}{\text{rate}_{\text{mL/hr}}} \] Substituting the given values: \[ \text{time}_{\text{hr}} = \frac{50}{200} = 0.25 \text{ hours} \]

To convert the time from hours to minutes, we multiply by 60: \[ \text{time}_{\text{min}} = \text{time}_{\text{hr}} \times 60 \] Substituting the calculated time in hours: \[ \text{time}_{\text{min}} = 0.25 \times 60 = 15 \text{ minutes} \]
