Question

A client who sustained a knee injury while skiing needs to receive an injection of betamethasone (Celestone) 10 mg IM. Available is a 30 mL multidose vial labeled 4 mg/mL. How many mL will you administer? (Place your answer to the 10th decimal and place only the numerical value in the space provided.)

Answer 1

To administer a 10 mg dose of betamethasone from a vial with a concentration of 4 mg/mL, one would need to administer 2.5 mL of the solution.

Step-by-step explanation:

The student's question relates to dosage calculation, which requires basic mathematical knowledge to solve. In this scenario, we need to calculate the volume of medication to administer based on the ordered dose and the concentration of the medication available. The client needs 10 mg of betamethasone, and the vial available has a concentration of 4 mg/mL. To find out how many mLs to administer, the ordered dose (10 mg) needs to be divided by the concentration of the medicine (4 mg/mL).

To calculate the volume:

• 
  

Therefore, the volume to administer is 2.5 mL.
