Answer 1

Step-by-step explanation:

The medication order is for Dilaudid (hydromorphone) 1-2 mg intramuscularly (IM) every 2-3 hours as needed for severe pain.

Interpretation of the order:

The order is for Dilaudid, a potent opioid analgesic (CII medication), to be given via intramuscular injection. The prescribed dose is 1-2 mg, and it can be administered every 2 to 3 hours as needed for severe pain.

Which ampule should be chosen for the 2 mg dose?

To deliver a 2 mg dose of Dilaudid, you should choose the 2 mg/mL ampule of hydromorphone injection. This strength will allow you to accurately measure and administer the 2 mg dose.

What volume is needed from this ampule for the 2 mg dose?

To calculate the volume needed from the 2 mg/mL ampule for a 2 mg dose, use the formula:

Volume (in mL) = Dose (in mg) / Concentration (in mg/mL)

Volume (in mL) = 2 mg / 2 mg/mL

Volume (in mL) = 1 mL

So, you will need to draw 1 mL from the 2 mg/mL ampule to administer the 2 mg dose of Dilaudid.
