Learning outcomes

What you will learn

  • Explain the difference between medication amount, solution volume, pump rate and elapsed time.
  • Find a concentration in mg/mL when an amount-in-volume label is given.
  • Use a verified infused volume directly, or calculate volume from mL/hr and time for one constant uninterrupted interval.
  • Use mg/mL and infused mL to calculate the medication amount represented by the supplied values.
  • Keep a medication amount in mg separate from a medication rate such as mg/hr.

Clinical connection

Why this matters

A single question can contain mg, mL, mL/hr and hours. Giving each number one clear job helps stop a fluid rate from being mistaken for a medication amount.
