Question

Nancy has been given the following physician order: Give 500 mg of a medication intramuscularly now. The drug that is available is 1000mg/1mL. The amount of the drug that Nancy should draw up is:

a.0.5 mL.
b.1 mL.
c.2 mL.
d.2.5 mL.

Answer 1

Nancy should draw up 0.5 mL of the medication because the volume of medication to administer is calculated by dividing the ordered dose by the concentration of the medication, resulting in 0.5 mL.

Step-by-step explanation:

The subject of this question is medicine, specifically the calculation of medication dosage. In the scenario provided, Nancy has been instructed to administer 500 mg of medication intramuscularly. The medication is available in a concentration of 1000 mg/mL.

To calculate the volume of medication Nancy should draw up, we use the following formula:

Volume to Administer (mL) = Ordered Dose (mg) / Concentration of Medication (mg/mL)

In this case, the volume Nancy should draw up is:

Volume to Administer = 500 mg / 1000 mg/mL = 0.5 mL

Therefore, the correct answer is a. 0.5 mL.
