without interfering with normal functioning
somatic pain - correct answer originates from skeletal muscle, ligaments, and joints
referred pain - correct answer pain that is felt in a location other than where the pain originates
visceral pain - correct answer originates from organs and smooth muscle
central pain - correct answer marked by chronic pain stemming from damage to CNS
bradykinin - correct answer causes vasodilation
What are adjuvant drugs? - correct answer assist primary drugs in relieving pain
what are opioid drugs? - correct answer synthetic drugs that bind to the opiate receptors to relieve pain
,mild agonist opioid drugs - correct answer codeine and hydrocodone
strong agonists - correct answer morphine, hydromorphone, oxycodone, meperidine, fentanyl, and
methadone
Can a nurse dilute opioid drugs in an iv? - correct answer No, not unless the pharmacy specifically says
to and opioids should not be given through a normal saline device
what is the opioid ceiling effect? - correct answer drug reaches a maximum analgesic effect
If you take 5 mg of a medication for pain, that 5 mg will go to receptor sites to block pain signals but let's
say you take 10 mg, What will happen? - correct answer . 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 overdose.
what do opioid agonists do? - correct answer bind to an opioid pain receptor site to block pain
what do opioid agonists-antagonists do? - correct answer bind to a pain receptor but causes a mixed
response, weaker than full agonist
what do opioid antagonists do? - correct answer blocks or takes out the agonist effects
ex: narcan reverses opioid overdose
what is Equianalgesia? - correct answer ability to provide equivalent pain relief by calculating dosages
that provide comparable analgesia.
opioid analgesics contraindications - correct answer known drug allergy, severe asthma,
COPD/respiratory insufficiency, pregnancy
,opioid analgesics indications - correct answer moderate to severe pain (7+), cough center suppression,
diarrhea, balanced anesthesia

C.Temperature
D. Respirations - correct answer D. respirations
opioid analgesics adverse effects - correct answer CNS depression, GI upset, urinary retention (check

what is a common opioid medication given for overdose? - correct answer Naloxone (Narcan)
what do opioid analgesics interact with? - correct answer alcohol, antihistamines, barbiturates, benzos
codeine sulfate - correct answer less effective, more commonly used as an antitussive
fentanyl - correct answer narrow therapeutic window; injection, patch, lozenges
Methadone Hydrochloride (Dolophine) - correct answer synthetic opioid analgesic, choice for
detoxification for opioid addicts, prolonged QT interval and causes cardiac dysrhythmias
, morphine sulfate - correct answer opioid analgesic, prototype; used for severe pain
Naxolone (Narcan) - correct answer opioid antagonist; for complete or partial reversal of opioid induced
respiratory depression
Acetaminophen (tylenol) - correct answer non-opioid analgesic; can alter liver function, antipyretic and
analgesic effects
Acetaminophen MOA - correct answer blocks pain impulses peripherally by inhibiting prostaglandin
synthesis
Acetaminophen indications - correct answer mild to moderate pain (3-5), fever, alternative to aspirin
Acetaminophen max dosage - correct answer <3000 mg/day
<2000 mg/day for older adults
Acetaminophen Contraindications - correct answer drug allergy, liver dysfunction, liver failure
