Final answer:
To determine the infusion time for 700 ml of an electrolyte solution at an infusion rate of 75 gtt/min, calculate the flow rate in ml/min using the given drop factor, then divide the volume by this new flow rate. The correct infusion time is 2 hours and 20 minutes, which is not an option in the provided choices.
Step-by-step explanation:
Calculating Infusion Time
The question asks us to calculate how long it will take to infuse 700 ml of an electrolyte solution at an infusion rate of 75 gtt/min with a drop factor of 15 gtt/ml. To find the time in hours and minutes, we can use the formula: Time (min) = Volume (ml) / (Flow rate (gtt/min) / Drop factor (gtt/ml)). Let's calculate the time:
- First, find the flow rate in ml/min using the drop factor:
- Flow rate = 75 gtt/min / 15 gtt/ml = 5 ml/min.
- Next, calculate the total time to infuse 700 ml:
- Time = Volume / Flow rate = 700 ml / 5 ml/min = 140 minutes.
- Convert 140 minutes to hours and minutes:
- Hours = 140 min / 60 min/hr = 2 hours.
- Minutes = 140 min % 60 min/hr = 20 minutes.
Therefore, the infusion will take 2 hours and 20 minutes.
However, this time frame is not listed among the provided answer choices, suggesting a possible error or discrepancy in the question.
