Exam 2 part 2 Flashcards
Know the difference between visceral pain, vascular pain, neuropathic pain and somatic pain, and acute pain and chronic pain
- Visceral pain – Pain that originates from organs
- Vascular pain – Pain that results from pathology of the vascular or perivascular tissues
- Neuropathic pain – Pain that results from disturbance of function or pathologic change in a nerve (tingling, numbness, pins and needles)
- Somatic pain – Pain that originates from skeletal muscle, ligaments or joints
- Acute pain – pain that is sudden in onset and when treated usually resides less than 6 weeks
- Chronic pain – Persistent or recurring pain that is often difficult to treat; includes any pain lasting longer than 3 to 6 months
KNow the meaning of opioid tolerance
• Opioid tolerance – normal physiological condition that results in long term opioid use in which larger doses of opioids are required to maintain the same level of analgesia and immediately withdraw can result in withdrawal symptoms
- Before administering an opioid analgesic what is the baseline data that the nurse must collect before administering this medication
• Check BP, respirations, bowel sounds (check every shift), pain level, LOC, allergies
- Why is meperidine (Demerol) not used in children and the elderly?
seizures
what is the receptor for opioids
MU
- What is a common adverse effect of opioids which is caused by histamine release?
itching
- What is the most serious adverse effect of opioids?
respiratory arrest
antidote for opioids
narcane (naloxone)
- Why might narcane(naloxone) be administered more than once in a patient who has overdosed on methadone or fentanyl patches?
• Narcane is short acting (short ½ life) so a 2nd dose may be required with opioids that have a long ½ life or that are delayed release or delivered through a patch form
Why should Demerol not be given to a patient taking selegiline(MAOI)?
• Seizures, respiratory depression, and hypotension
- Why should a patient who is opioid naïve not take fentanyl? What is a definition of opioid tolerant?
• Fentanyl could kill an opioid naïve patient. See above for opioid tolerant
- What is daily limit of the dose of Tylenol(acetaminophen)?
4 g (4000 mg)
- What are contraindications for acetaminophen?
• Contraindications for Tylenol are: liver disease, alcoholic, G6PD and the antidote for Tylenol is Acetylcysteine(mucomyst).
What is the medication that is used for a benzodiazepine overdose?
flumazenil
- What is the drug food interaction that needs to be avoided with benzodiazepines?
• Grapefruit juice and grapefruits should be avoided because of their interaction with the cytochrome P 450 enzyme in the liver would could increase the risk of toxicity for Tylenol. Also, alcohol is contraindicated.
- What are the adverse effects for the elderly who are taking benzodiazepines?
falls
- What is the primary inhibitory neurotransmitter of the brain?
GABA
- What is the main adverse effect of ambien?
sleep walking and sleep driving
- Is Ramelteon(Rozerem) a controlled substance and what hormone is this medication related to?
no. melatonin
- What are the major contraindications for muscle relaxants such as Baclofen(Lioresal)?
drug allergy and renal impairment
- How do amphetamines and phenidates increase the effect of norepinehphrine and dopamine?
• Amphetamines and phenidates increase the release and block the reuptake of dopamine and norepinephrine
When educating a family member on the drug methylphenidate (Ritalin), what time should the patient take this medication?
at least 6 hours before bedtime
