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.
