Question

A patient is ordered 0.5mg of Hydromorphone Hydromorphone SC q1h PRN. is available in a 2mg/ml concentration contained in 1ml vials. How much do you give per dose?

Answer 1

To calculate how much Hydromorphone to give per dose, use the formula mL = mg / concentration. In this case, you would give 0.25mL per dose.

Step-by-step explanation:

To calculate how much Hydromorphone to give per dose, we need to first determine the dose in milliliters (mL).

The order is for 0.5mg of Hydromorphone. We know that the concentration of Hydromorphone in the vial is 2mg/mL.

To find the mL/dose, we can use the formula mL = mg / concentration:

mL = 0.5mg / 2mg/mL = 0.25mL.

Therefore, you would give 0.25mL per dose.
