The infusion will be completed at 19:31
The medicine that the nurse is giving the patient is 1 gram of ampicillin diluted in 50 mL of dextrose water.
This means 50 mL + 1 mL = 51 mL. 1 gram of ampicillin = 1 mL considering all water-based substances have a density of 1gm/mL.
Now, the set delivers 15 ggt or drops per mililiter. Let's calculate the total drops in the 51 mL.
51mL x 15ggt =765 drops
Finally, we know the medicine is given at a rate of 25 drops per minute. Let's calculate the time:
- 765 drops / 25 drops per minute = 30.6 minutes
This means the medicine it will take 30.6 minutes for the infusion to be completed and therefore the infusion will be completed at 19:31 (19:00 + 30.6 minutes = 19:30.6 or 19:31).
