The physician orders dyphylline Elixir 200 mg po. The nurse has available dyphylline Elixir 100 mg/mL. How many mL will the nurse administer to deliver one dose? (Record your answer using a whole number)

a) 1 mL
b) 2 mL
c) 100 mL
d) 200 mL

Answer 1

The nurse needs to administer 2 mL of dyphylline Elixir to deliver the ordered 200 mg dose, based on the Elixir concentration of 100 mg/mL.

Step-by-step explanation:

The question asks how many milliliters (mL) of dyphylline Elixir the nurse should administer to deliver a single dose of 200 mg, given that the concentration of the elixir is 100 mg/mL. To calculate the required volume, you use the following simple dosage calculation formula:

Dose ordered (mg) / Concentration of medication (mg/mL) = Volume to be given (mL)

In this case:

200 mg / 100 mg/mL = 2 mL

Therefore, the nurse will administer 2 mL of dyphylline Elixir to deliver a 200 mg dose.
