NSG 552 EXAM 3 Flashcards
Cluster of disorders in which cognitive, behavioral and physiological symptoms indicate that a person continues using a substance despite substance-related problems (American Psychiatric Association, 2013)
“Sub-“
Substance Use Disorders
Drug use that is inconsistent with social use patterns.
“abu-“
Abuse
Reversible syndrome caused by a specific substance affecting memory, judgement, behavior or social or occupational functioning
“intox-“
Intoxication
Substance specific symptoms that occur after stopping or reducing use (opposite of the drug’s intoxication symptoms).
“withd-“
Withdrawal
Needing more of the substance to get the desired effect.
“Tol-“
Tolerance
Reinforcement occurs in the:
“Ven- teg-“ and “Nuc- accu-“
Ventral tegmental area (VTA) and the Nucleus accumbens (Reward center)
Positive rewards of reinforcement= mediated by ____ pathways.
“D-“
DA (dopamine)
____________ release within the reward center is enhanced by the release of natural morphine-like neurotransmitters (Neuropeptides- enkaphalins, beta endorphins).
“Dop-“
DA (dopamine)
Repeated drug use —> ________ system becomes increasingly sensitized.
“Dop-“
DA (dopamine)
Classes of Substance Use Disorders:
Caffeine, nicotine, amphetamines, cocaine, ecstasy
“stim-“
stimulants
Classes of Substance Use Disorders:
Benzodiazepines, Alcohol
“depr-“
depressants
Classes of Substance Use Disorders:
Opioids
“narc-“
narcotics
Classes of Substance Use Disorders:
Lysergic acid diethylamide (LSD) Marijuana
“hall-“
hallucinogens
- Impaired fine motor control
- Impaired judgement and coordination
- Ataxic gait and poor balance
- Lethargy, difficulty sitting upright, difficulty with memory,
- Nausea/Vomiting
- Coma = Levels 300mg/dL and over
- Respiratory depression and death possible
This is?
“alc- intox-“
alcohol intoxication
Mild: Insomnia, Irritability, Hand tremor
Moderate: Autonomic hyperactivity (diaphoresis, tachy, HTN), Fever
Severe: Seizures (12-48 hours post consumption); Hallucinations; Delirium Tremens (48-96 hours after last drink)
- Anxiety
- Anorexia
- Nausea/Vomiting
- Psychomotor agitation
NOTE: Use the Clinical Institute Withdrawal Assessment(CIWA) to monitor withdrawal
What is this?
“alc- withd-“
alcohol withdrawal
________ withdrawal: Insomnia, Irritability, Hand tremor
“mil-“
mild
________ withdrawal: Autonomic hyperactivity (diaphoresis, tachy, HTN), Fever
“mod-“
moderate
________ withdrawal: Seizures (12-48 hours post consumption); Hallucinations; Delirium Tremens (48-96 hours after last drink)
“sev-“
severe
Alcohol Withdrawal delirium: Initial treatment is a ___________.
Careful with the use of antipsychotics because they lower the seizure threshold.
“benz-“
benzodiazepine
____________________: Initial treatment is a benzodiazepine.
Careful with the use of antipsychotics because they lower the seizure threshold.
“alc- wit- del-“
Alcohol Withdrawal delirium
Alcohol Withdrawal delirium: Initial treatment is a benzodiazepine.
Careful with the use of antipsychotics because the lower the _______ threshold.
“seiz-“
seizure
Alcohol Withdrawal delirium: Initial treatment is a benzodiazepine.
Careful with the use of _____________ because the lower the seizure threshold.
“anti-“
antipsychotics
- Opioid receptor antagonist
- Reduces desire/cravings
- First line treatment – Good for heavy drinkers
- PO or monthly injection (Vivitrol) - great for patients with non-compliance issues.
- Will precipitate withdrawal in patients with physical opioid dependence.
- D/C 48-72 hours prior to receiving opiate analgesia.
Which med is this?
“nalt-“
naltrexone (Revia, Vivitrol [IM])
Functions as “artificial alcohol” by reducing glutamate activity.
- Reduces neuronal hyperactivity during early alcohol recovery – helps sustain abstinence.
- Likely modulates glutamate transmission
- First line treatment in maintaining abstinence after detox
- Used for relapse prevention (post detoxification)
- Can be used in liver disease- not metabolized by the liver (not impacted by ETOH use)
- Can be administered to patients with hepatitis, liver disease and those who continue drinking alcohol
- Contraindicated in severe renal disease.
- Decreases craving – good for individuals who are abstinent or recently relapsed.
Which med is this?
“acamp-“
acamprosate (Campral)
