Clinical Judgment w/ Blood Pressure and Pain Medication

Hello all,

I am a new grad nurse fresh off orientation and I seem to be running into this issue quite a bit on the telemetry floor.. Patients with low blood pressures (80/50) in pretty severe pain, asking for pain medication. Most of the time they're ordered morphine 2 or 4 mg q 6 or even Dilaudid 1 mg q4. I would know not to give anything like morphine or dilaudid for a patient with a blood pressure like 80/50, but what about Percocet or Vicodin? Will those drugs also drop the BP? and if so, by how much? Is it drastic?

I have been searching the web for some good research and answers as to exactly HOW MUCH it will go down and I can't seem to find anything. I know the readers here have a ton of experience and I feel like that sharing would be most valuable in answering my question and I also understand that it depends on the patient. If any of you have experience with dropping blood pressures from administering various pain medications, do share! As much information as possible is appreciated!

I also gave Toradol the other day and I'm wondering if it's analgesic effect is stronger/weaker in comparison to the other IV narcotics.

Thank you!
