HESI Dosage Calculations Practice Exam

To determine the correct gtts/minute setting for the IV administration, you can use the formula for calculating the rate of infusion. First, calculate the total volume of fluid to be infused and the total time in minutes.

In this case, the total volume of Lactated Ringer's solution is 1,000 ml, and it needs to be infused over 10 hours. Convert the infusion time in hours to minutes:

10 hours × 60 minutes/hour = 600 minutes.

Next, you need to calculate the flow rate in milliliters per minute:

1,000 ml ÷ 600 minutes = approximately 1.67 ml/minute.

Now, given that the administration set delivers 60 drops (gtts) per milliliter, multiply the flow rate by the drop factor to convert the flow rate from ml/minute to gtts/minute:

1.67 ml/minute × 60 gtts/ml = 100 gtts/minute.

Therefore, the correct answer for the IV administration set to ensure the client receives the prescribed volume at the correct rate is 100 gtts/minute. This setting will allow for the proper infusion of fluids following the surgical procedure, ensuring the client's hydration and recovery needs are met adequately
