Question

Order medication V 0.2 mg to be given intramuscular,

immediately. The medication label states Medication V 400 mcg/mL.
How many mL should the nurse prepare to administer the correct
dose?

Answer 1

To administer 0.2 mg of Medication V, the nurse needs to prepare 0.5 mL of the solution based on the medication's concentration of 400 mcg/mL.

Step-by-step explanation:

The student has asked how to prepare the correct dose of medication V, given the order of 0.2 mg and a medication label that states Medication V 400 mcg/mL. To convert the dose required (0.2 mg) to micrograms, one must know that 1 mg is equivalent to 1000 micrograms. Therefore, 0.2 mg is the same as 200 mcg. The concentration of the medication provided is 400 mcg/mL, which means for every 1 mL, there are 400 mcg of the medication.

To calculate the volume (mL) needed to provide 200 mcg of the medication, use the formula: Volume (mL) = Dose required (mcg) / Concentration (mcg/mL). The calculation is: Volume (mL) = 200 mcg / 400 mcg/mL equals 0.5 mL.

Therefore, the nurse should prepare 0.5 mL to administer the correct dose of 0.2 mg of Medication V intramuscularly.
