Question

A nurse is preparing to administer fluoxetine 35 mg PO daily. Available is fluoxetine solution 20mg/5mL. How many mL should the nurse administer daily?

Answer 1

8.75mL fluoxetine

Step-by-step explanation:

To solve for the amount to be administered, we multiply the ordered dose by its concentration (represented by a mL / mg or mg / mL)

35mg x (5 mL / 20mg)
= 35 mg (5 mL) / 20 mg
= 175 mg mL / 20 mg
mg in numerator and denominator will cancel each other
= 175 mL / 20
= 8.75 mL

The nurse should prepare to administer 8.75 mL of fluoxetine solution
