The most common orders to calculate flow rates involve large and small volume IM injections.
 False
 The most common orders to calculate flow rates involve IVs.

Flow rates are usually expressed as drops per hour or milliliters per minute.
 False
 Flow rates are usually expressed as drops per minute or milliliters per hour.

Flow rates represent how much medication a patient will receive over a period of time.
 True
 Flow rates represent how much volume of a medication a patient will receive over a period of time.

The first segment in the flow rate formula, volume per hour, is represented as mL/hr.
True

If no number is given for the second segment of the flow rate formula, assume 20 drops/mL for IV administration.
 False
 If no number is given for the second segment, assume 60 drops/mL for IV administration.

The third segment of the flow rate formula helps to convert minutes to hours.
 False
 The third segment helps to convert hours to minutes.

Equation for flow rate calculation
drops/minute = mL/hour x drops/1 mL x 1 hour/60 minutes

Infusion time calculations are helpful in determining a drug concentration.
False

Infusion time calculations are helpful in determining how much medication a patient will receive over a period of time.
False

Infusion time calculations are helpful in determining when an IV needs to be replaced.
True

Infusion time calculations are helpful in determining the w/v% of a preparation.
False

Infusion time equation
Infusion time (hr) = Total volume of infusion x drops/mL x min/drop x 1 hr/60 min
