Answer:
100 drops per minute, 100 gtt/min
Explanation:
The 500 mg of fluoroquinolone antibiotic levofloxacin (brand name Levaquin) mixed within 100 mL of normal saline to be infused over 1 hour.
The tubing through which it will be infused has a drop factor of 60 drops per mL (60 gtt/mL).
Given the volume of medication over a given amount of time and the drop factor, the amount of drops per minute that will be infused can be determined by multiplying to two rates together. The following formula can be used to represented in this calculation:
(volume to be infused / duration) × drop factor
Calculation:
The volume to be infused in the 100 mL. The duration of infusion is 1 hour, or 60 minutes (60 min). The drop factor is given as 60 gtt/mL
[tex]\frac{100mL}{60 min} (\frac{60 gtt}{mL})[/tex]
mL in both numerator and denominator will cancel each other out, leaving gtt/min as the remaining units.
[tex]\frac{100}{60min}(60 gtt)[/tex]
= 6000 gtt / 60 min
= 100 gtt / min
The levofloxacin is to be infused at a rate of 100 gtt/min.
The levofloxacin should be infused at 100 drops per minute.
To calculate the number of drops per minute:
Identify the total volume to be infused: 100 mL.
Identify the total time for infusion: 1 hour (60 minutes).
Use the formula: (Total Volume in mL / Total Time in minutes) x Drop Factor (GTT/mL) = Drops per minute.
Applying the values:
Total Volume: 100 mL
Total Time: 60 minutes
Drop Factor: 60 GTT/mL
Calculation: (100 mL / 60 minutes) x 60 GTT/mL
= 100 drops per minute.
