b) 2 mL
c) 3 mL
d) 300 mL

Answer 1

The nurse will administer 3 mL of dyphylline elixir to deliver a 300 mg dose, calculated by dividing the prescribed dose by the medication concentration.

Step-by-step explanation:

The question asks how many milliliters (mL) of dyphylline elixir the nurse should administer to deliver a 300 mg dose, given that the concentration of the elixir is 100 mg/mL. To find the volume of medication to administer, one needs to divide the prescribed dose by the concentration of the medication.

Calculation:
Prescribed dose = 300 mg
Concentration of dyphylline elixir = 100 mg/mL
Volume to administer (V) = Prescribed dose / Concentration

V = 300 mg / 100 mg/mL = 3 mL

Hence, the nurse will administer 3 mL of dyphylline elixir to deliver a 300 mg dose.
