17
Q

Acetaminophen ( Tylenol) teaching

A
  • take as directed - MAX DOSE: 4000 mg total in a day - geriatric and people with liver problems : 2000 mg per day or less -be aware of other meds that end with cet: darvocet, lorcet, dulcet … Vicodin, typically, wygesic
18
Q

Tramadol ( ultram ) -

A

moderate to severe pain -SE: N&V , constipation, HA, anxiety, seizures - schedule 4 - but risk of addiction - should be treated like codiene

19
Q

opioids

A

•pain relievers that contain opium, •or derived from the opium poppy •or chemically related to opium •Act primarily in the CNS

20
Q

Controlled substance act

A

“5” schedule categories- based on their potential for abuse

21
Q

addiction ( Psych & physical dependence)

A

A pattern of compulsive drug use characterized by a continued craving for an opioid and the need to use the opioid for effects other than pain relief

22
Q

opioid analgesics-

indication

A

Indications:

  • relieve moderate to severe pain
  • Codeine—mild to moderate pain
  • cough suppression
  • relieve diarrhea

**No Ceiling Effect**

23
Q

Common opioids

A
  • Morphine Sulfate (Roxanol)—PO, IV, IM, SQ, SL,Rectal
  • (MSContin)
  • Hydromorphone (Dilaudid) PO, IV, SC, IM, Rectal
  • Meperidine (Demerol)—PO, IM, IV
  • Fentanyl (Duragesic)—PO, IV, IM, Transdermal, Lozenge (lollipop)-Duragesic Patch

Oxycodone—PO

  • Oxycontin
  • Percocet =Oxycodone+ Acetaminophen
  • Percodan=Oxycodone+Aspirin

  • Vicodin=Hydrocodone+ Acetaminophen
  • Codeine Sulfate—PO, SQ, IM
  • Tylenol #3 = Codeine + Acetaminophen
24
Q

opioid SE/AE

Q

opioid analgesic:

Nursing processes

A

**Important for administration of any analgesic med**

  • ASSESSMENT
  • Perform a thorough pain assessment, including

nature and type of pain, precipitating and

relieving factors, remedies, and other pain

treatments.

  • “Fifth vital sign”
  • Critical assessments: Respirations, BP, Pain

level/description/location; Last dose

  • DIAGNOSIS
  • Example: Acute pain related to disruption of

tissue secondary to right hip

arthroplasty

•PLAN=”which pain med to give?”

30
Q

opioid :

Implement

A
  • After assessment determine which pain med to administer
  • Patient teaching
  • Oral forms should be taken with food to

minimize gastric upset

  • Ensure safety measures
  • Assess VS
  • Low BP and/or Respiratory depression

–Hold dose and contact physician

•May need to give Opioid antagonist

-Monitor for other side effects

  • Constipation
  • Orthostatic Hypotension
  • Instruct patients to not take other meds or OTC

preparations

Follow proper administration guidelines for IM

injections and IV administration

**CHECK DOSAGES CAREFULLY**

  • Special populations
  • Adjuvant therapy
  • Addiction concerns
