A patient requires 80 milligrams of Risperidone. The stock dose is 40mg / 10mL. What volume is required?
show all steps
To calculate the required volume, we can use the formula:
Volume (mL) = (Required dose (mg) / Stock dose (mg/mL))
Given that the required dose is 80mg and the stock dose is 40mg/10mL, we can substitute these values into the formula:
Volume (mL) = (80mg / 40mg/10mL)
First, we simplify the fraction in the denominator:
Volume (mL) = (80mg / 4mg/mL)
Next, we divide the required dose by the stock dose:
Volume (mL) = 20 mL
Therefore, the volume required is 20 mL.
