Q

Biologic Risk Factors for Substance Misuse

A

Genetics: Children of alcoholic parents are at higher risk for developing alcoholism and drug dependence than are children of nonalcoholic parents
- Increased risk is partly the result of environmental factors, but evidence points to the importance of genetic factors as well
- Adoption studies have shown higher rates of alcoholism in sons of biologic fathers with alcoholism than in those of nonalcoholic biologic fathers
->These studies led theorists to describe the genetic component of alcoholism as a genetic vulnerability that is then influenced by various social and environmental factors

Brain’s Reward Center Theory: Addictive substances or behaviors affect the brain’s reward system by flooding the nucleus accumbens with dopamine

  • Repeated exposure causes nerve cells in the nucleus accumbens and prefrontal cortex to couple liking something with wanting it
  • This motivates someone to seek the pleasure source

Q

Designer Drugs

A

AKA Club Drugs

Synthetic substances made by altering existing medications or formulating new ones not yet controlled by the FDA
- Amphetamine-like effects, some also have hallucinogenic effects

As attempts to make such drugs illegal are formulated, makers of the drugs alter the substance slightly so it once again falls outside the law.

They may also contain unknown compounds as a filler or additive, and the effects are unknown until the drug is ingested.

Some of these substances are known by generic terms such as bath salts or plant food, although the substances are never used for those purposes.
- Others have specific names, such as ecstasy (methylenedioxymethamphetamine), special K (Ketamine), or smiles (2C-1)

Signs & Symptoms of Alcohol Intoxication

Study These Flashcards
A

Slurred speech
Memory Impairment
Altered judgement
Decreased motor skills/ unsteady gait
Decreased LOC (stupor, coma)
RESPIRATORY ARREST
Peripheral collapse
Death (w/large doses)
May experience a blackout

25
Early Onset of Alcohol Misuse
Prognosis: Unclear, only people with alcohol problems seeking treatment have been studied In the United States, the average age for an initial alcohol intoxication episode is during adolescent years - The 1st episode of intoxication between 12--14 years of age - The 1st evidence of minor alcohol-related problems is seen in the late teens Episodes of “sipping” alcohol may occur at age 8 years or even earlier
26
"Middle" Clinical Course of Alcohol Use
A pattern of more severe difficulties for people with alcoholism begins to emerge in the mid-20s to the mid-30s These difficulties can be: - The alcohol-related breakup of a significant relationship - An arrest for public intoxication or driving while intoxicated - Evidence of alcohol withdrawal - Early alcohol-related health problems, or significant interference w/ functioning at work or school During this time, the person experiences their 1st blackout As the person continues to drink, they often develop a tolerance for alcohol After continued heavy drinking, the person experiences a tolerance break
27
Blackout
An episode during which the person continues to function but has no conscious awareness of their behavior at the time or any later memory of the behavior
28
Tolerance Break
Very small amounts of a substance will produce intoxication
29
Later Course of Alcohol Misuse
The later course of alcoholism, when the person’s functioning is definitely affected, is often characterized by periods of abstinence or temporarily controlled drinking Abstinence may occur after some legal, social, or interpersonal crisis, and the person may then set up rules about drinking, such as drinking only at certain times or drinking only beer This period of temporarily controlled drinking soon leads to an escalation of alcohol intake, more problems, and a subsequent crisis The cycle repeats continuously
30
Signs & Symptoms of an Alcohol Overdose
Vomiting Unconsciousness Respiratory depression Alcohol-induced hypotension: Can lead to CV shock & death Combo of symptoms can cause aspiration pneumonia or pulmonary obstruction
31
Treatment of Alcohol Overdose
Gastric lavage or dialysis to remove the drug and support of respiratory and cardiovascular functioning in an intensive care unit. The administration of CNS stimulants is contraindicated
32
What is the relapse range rate?
Range from 60% to 80%, with nearly half of individuals relapsing in the year after treatment A minority of people remain sober after the first treatment experience The highest rates for successful recovery are for people who: - Abstain from substances - Highly motivated to have a substance-free lifestyle - Who actively work on relapse prevention
33
Spontaneous Remission
Natural recovery that occurs without treatment of any kind
34
Wernicke's Encephalopathy
Degenerative brain disorder related to vitamin B1 deficiency Acute & reversible
35
Signs & Symptoms of Wernicke's-Korsakoff Syndrome
Abnormal eye movement Confusion Confabulation Hallucinations Double vision Memory loss Inability to form new memories Loss of muscle coordination
36
Treatment for Wernicke's Syndrome
Large doses of thiamine IV 2-3 X daily for 1-2 weeks May progress into Korsakoff’s syndrome if untreated
37
Korsakoff Syndrome
CHRONIC!!! Memory disorder resulting from vitamin B1 deficiency Treatment: Thiamine for 3-12 months Recovery rate is 20%
38
Alcohol Withdrawal
Classic Signs: Tremulousness Mild to Moderate Withdrawal: Agitation, N/V, insomnia, impaired cognition - Temp, pulse, & BP increase Severe Withdrawal: MEDICAL EMERGENCY!!! - Psychosis which can lead to unconsciousness, seizure (grand-mal = deadly), & delirium - Alcohol w/drawal delirium or DT's (Delirium Tremens) (Usually see bugs crawling around)
39
If the client's withdrawal symptoms are mild & they can abstain from alcohol...
...they can be treated safely at home (pg. 360)
40

...short admission of 3-5 days is the more common setting
41
Treatment for Alcohol Withdrawal

42
When does alcohol withdrawal start?
Between 3 hrs- 3 days after last drink
43
Why is it important to obtain the client's VS before each dose of benzodiazepine for alcohol withdrawal?
To watch for the response to treatment & signs of impending respiratory distress Pay close attention to the patient's respirations!!!
44
Tapering
Administering decreasing doses of a medication, leading to discontinuation of the drug
45

The presence and severity of withdrawal symptoms determine the amount of medication needed & the frequency of admin
