Question

Use either the Step 1 or the Step 2 formula to calculate mL per hr or drops per min to answer te following questions. Indicate STEP 2 if you only used it to solve the problem or indicate both Stie 1 and STEP 2 if both were needed. 1. Ordered: 1000 mL to be infused for 12hr on microdrip. At how many drops per min will 10. regulate the infusion? 2. You have 1500 mL normal saline (NS). The drop factor is 15. The solution is to be given for an 8-hr period. a. How many mL per hr will be infused? b. How many drops per min will be infused? 3. A solution of 3000 mL D5W with 1.5 g carbenicillin is being infused for 24hr. The drop factor is 15 drops per minute. How many drops per min will be infused? 4. You have 500 mL0.45% NS infusing for 4hr. The drop factor is 15 . How many drops per min will be infused? 5. Ordered: 2000 mL for 24hr. The drop factor is 15 . How many drops per min will be administered? 6. Ordered: 100 mL gentamicin to be infused for 30 min. The drop factor is 20 . How mary drops per min will be infused? 7. You have 2000 mL D5W being infused for 24hr. How many mL per hr will be infused? 8. Ordered: 250 mL D5W is to be infused for 10hr on a microdrip. How many drops per mili will be administered?

Answer 1

To infuse 1000 mL over 12 hours using a microdrip, one must set the IV flow rate to 83.33 drops per minute by first calculating the mL/hr and then converting to drops/min.

Step-by-step explanation:

The student's question relates to the calculation of the flow rate of an IV (intravenous) drip, specifically converting a volume to be infused over time into a rate of drops per minute. Using the information provided, the student must determine the flow rate required to infuse 1000 mL of IV fluid over a 12-hour period using a microdrip setup, which delivers 60 drops per mL.

To calculate the drops per minute:

1. First, divide the total volume ordered (1000 mL) by the total time in hours (12 hours) to find the rate in mL/hr.
   1000 mL / 12 hr = 83.33 mL/hr
2. Then, convert the flow rate from mL/hr to drops/min by multiplying by the drop factor (60 drops/mL) and dividing by the number of minutes in an hour (60).
   (83.33 mL/hr) × (60 drops/mL) / 60 min/hr = 83.33 drops/min

The answer indicates that the IV should be regulated to 83.33 drops per minute to achieve the ordered rate of infusion using a microdrip.
