Final answer:
To administer 800 mL of Hespan over 4 hours with a drop factor of 15 gtt/mL, 50 drops per minute should be given.
Step-by-step explanation:
The question asks how many drops per minute should be administered to infuse a total of 800 mL of Hespan over 4 hours when the drop factor is 15 gtt/mL. To solve this, we first calculate the total number of drops by multiplying the total volume by the drop factor: 800 mL × 15 gtt/mL = 12,000 gtt. Next, we calculate the number of hours in minutes, which is 4 hours × 60 minutes/hour = 240 minutes. Then, we divide the total number of drops by the total number of minutes to find the drops per minute: 12,000 gtt / 240 minutes = 50 gtt/minute. Therefore, 50 drops per minute should be given to infuse the total amount of Hespan over 4 hours.
