what are analgesics? - ansmedications that relieve pain without loss of consciousness

what is a pain tolerance? - ansdifferent for everyone, amount of pain a person can endure
without interfering with normal functioning
somatic pain - ansoriginates from skeletal muscle, ligaments, and joints
referred pain - anspain that is felt in a location other than where the pain originates
visceral pain - ansoriginates from organs and smooth muscle
central pain - ansmarked by chronic pain stemming from damage to CNS
bradykinin - anscauses vasodilation
What are adjuvant drugs? - ansassist primary drugs in relieving pain
what are opioid drugs? - anssynthetic drugs that bind to the opiate receptors to relieve pain
mild agonist opioid drugs - anscodeine and hydrocodone
strong agonists - ansmorphine, hydromorphone, oxycodone, meperidine, fentanyl, and
methadone
Can a nurse dilute opioid drugs in an iv? - ansNo, not unless the pharmacy specifically says
to and opioids should not be given through a normal saline device

signals but let's say you take 10 mg, What will happen? - ans. Even if you increase the dose,
it will have the same effect no matter how much you take, can have more of an adverse effect
(why the pt may take more and more of something and then take more and then they begin to

what do opioid agonists-antagonists do? - ansbind to a pain receptor but causes a mixed
response, weaker than full agonist
what do opioid antagonists do? - ansblocks or takes out the agonist effects

that provide comparable analgesia.

COPD/respiratory insufficiency, pregnancy
opioid analgesics indications - ansmoderate to severe pain (7+), cough center suppression,
diarrhea, balanced anesthesia
