A nurse is preparing to administer fluoxetine 15 mg PO to a client who has premenstrual dysphoric disorder. Available is fluoxetine oral solution 20 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3.8\u00a0"]
Rationale:
How to solve it:
Determine the dosage required: 15 mg
Determine the concentration available: 20 mg/5 mL
Use the formula:
Volume (mL)=Required dose (mg)/Concentration (mg/mL)
Convert the concentration into a simpler fraction:
20 mg/5 mL=4 mg/mL
Calculate the volume:
Volume (mL)=15 mg/4 mg/mL
Simplify the calculation:
Volume (mL)=3.75 mL
Round to the nearest tenth:
3.8 mL

Correct Answer is ["2.5"]
Explanation
Step by step calculation:
Determinethetotaldailydosageingrams:0.032g
Convertgramstomilligrams:
0.032g×1000mg/g=32mg
Dividethetotaldailydoseintofourequaldoses:
Doseperadministration=32mg/4=8mg
Determinetheconcentrationavailable:16mg/5mL
Usetheformula:
Volume(mL)=Requireddose/(mg)Concentration(mg/mL)
First,findthemg/mLconcentration:
16mg/5mL=3.2mg/mL
Nowcalculatethevolume:
Volume(mL)=8mg/3.2mg/mL
Volume(mL)=2.5
Correct Answer is ["1.2"]
Explanation
Step by step calculation:
Determinethedosagerequired:3mg
Determinetheconcentrationavailable:2.5mg/mL
Usetheformula:
Volume(mL)=Requireddose/(mg)Concentration(mg/mL)
Volume(mL)=3mg/2.5mg/mL
Calculatethevolume:
Volume(mL)=1.2
