A nurse is preparing to administer paliperidone 234 mg IM to a client. Available is paliperidone 273 mg/0.875 mL. How many ml. should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.75"]
Step by step calculation:
Determine the dosage required: 234 mg
Determine the concentration available: 273 mg/0.875 mL
Use the formula:
Volume (mL)=Required dose /(mg)Concentration (mg/mL)
First, find the mg/mL concentration:
Concentration (mg/mL)=273 mg/0.875 mL=312 mg/mL
Now calculate the volume:
Volume (mL)=234 mg/312 mg/mL
Volume (mL)≈0.75

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
