Tagamet 300 mg IVPB q8hr. The medication has been added to 50 mL DSW to infuse over 30 minutes. How many ml/hr?
Explanation & Rationale
Given: Volume of fluid: 50 mL (DSW) Infusion time: 30 minutes Formula: Flow rate (mL/hr) = Volume (mL) / Time (hr) Step 1: Convert infusion time to hours: Infusion time (hr) = 30 min / 60 min/hr Infusion time (hr) = 0.5 hr Step 2: Calculate the infusion rate in mL/hr: Flow rate (mL/hr) = Volume (mL) / Infusion time (hr) Flow rate (mL/hr) = 50 mL / 0.5 hr Flow rate (mL/hr) = 100 mL/hr
