A physician has ordered 0.50 mg of atropine, intramuscularly. If atropine were available as 0.25 mg mL of solution, how many milliliters would you need to give?
Express the volume in milliliters to two significant figures.
To find the volume of solution needed, we can use the following formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case, the desired dose is 0.50 mg and the concentration is 0.25 mg/mL. Plugging these values into the formula, we get:
Volume (mL) = 0.50 mg / 0.25 mg/mL = 2 mL
Therefore, you would need to administer 2 mL of the solution to deliver 0.50 mg of atropine intramuscularly.
To calculate the number of milliliters needed to give 0.50 mg of atropine intramuscularly, we can use the formula:
Volume (mL) = Amount of medication (mg) / Concentration (mg/mL)
In this case, the amount of medication is 0.50 mg, and the concentration is 0.25 mg/mL.
Plugging these values into the formula, we get:
Volume (mL) = 0.50 mg / 0.25 mg/mL
Simplifying the equation, we have:
Volume (mL) = 2 mL
Therefore, you would need 2 milliliters of the solution to administer 0.50 mg of atropine intramuscularly.
