Question

A physician has ordered 0.50 mg of atropine, intramuscularly. If atropine were available as 0.10 mg/mL solution, how many mL would u need to give?

Answer 1

To administer 0.50 mg of atropine from a 0.10 mg/mL solution, you would need to give 5 mL of the solution.

Step-by-step explanation:

To calculate the volume of a 0.10 mg/mL atropine solution needed to obtain a dosage of 0.50 mg, we can set up a simple equation using dimensional analysis:

Since the physician has ordered 0.50 mg of atropine and the available solution is 0.10 mg/mL, we need to determine how many milliliters (mL) would provide the ordered dose.

The calculation we need to perform is:

• Desired dose (mg) ÷ Concentration of solution (mg/mL) = Volume of solution (mL)
• 0.50 mg ÷ 0.10 mg/mL = 5 mL

Therefore, you would need to administer 5 mL of the atropine solution to provide the ordered 0.50 mg dose.

Answer 2

x * 0.10 mg/mL = 0.50 mg

x = 0.50 mg / 0.10

x = 5.0 mL

hope this helps!
