ATI Pharmacological and Parenteral Therapies Practice Test

To determine the correct IV pump setting in mL/hr for administering clindamycin at a dose of 900 mg over 30 minutes in 100 mL of D5W, it is important to calculate the infusion rate based on the total volume and the time over which it will be administered.

The total volume to be infused is 100 mL. The infusion is scheduled to occur over a period of 30 minutes. To convert this timeframe into hours, you can divide 30 minutes by 60, resulting in 0.5 hours.

Next, to calculate the rate in mL/hr, you would use the formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Time (hr)

Substituting in the known values:

Infusion Rate = 100 mL / 0.5 hr = 200 mL/hr

This indicates that the correct IV pump setting should indeed be set to 200 mL/hr for the administration of the clindamycin over the specified duration. Therefore, selecting this option is accurate in reflecting the necessary infusion rate to ensure that the medication is given properly within the allotted timeframe.
