40
Q

● Recall when you first drank alcohol, what prompted you to continue to drink after that initial drink?
○ It depends on social factors such as being with friends
○ Religious Factors ○ Genetics
■ If most family members are drinking, it is much easier to continue drinking
■ Not all become dependent on alcohol
● Reduce tension and stress, but in high doses can incur the
opposite
● There is an increased feeling of “power”
○ You feel that you can do anything because of your lowered inhibitions
○ You become more outgoing and talkative when you consume alcohol when you are typically quiet
● The increased feeling of power and the decreased effects of psychological pain are difficult to evaluate definitively

A

Psychological theories

41
Q
  • “unconscious”
  • not think of or aware but it still affects u
  • encompasses large portion of stress when compared w conscious
  • help w self-punitive/self-harm behavior
  • perfectionist, self super ego
  • high moral std
  • those easily feel guilt

Alcohol decreases unconscious stress lvls
- stress but unaware thus alcohol

Fixation of the oral stage of development
- freudian hypothesis, fixated
- relieve frustration, subs are taken in by mouth

A

Psychodynamic theories

42
Q

● schizophrenia ●
Why do you continue to drink after the first experience with alcohol despite having problems while drinking? Expectations about rewarding effects
○ You know that the good feeling will happen again, so you continue to drink
There’s the cognitive attitude towards the responsibility for one’s behavior. You believe that you can control the drinking and that you can stop yourself at any time Subsequent reinforcement after alcohol intake. It will lower inhibitions, you become more sociable.

A

Behavioral theories

43
Q

● Cultural attitudes towards drinking, drunkenness, and personal responsibility for consequences are important contributors to the rates of alcohol related problems in a society.
○ The environment is also part of biopsychosocial.

A

Sociocultural theories

44
Q

● It has been proven in research that even twins that are raised from different families and become dependent
● Even within the family, the grandfather who is a drinker, then the father, the son and so on.
● There is the genetic theory but also confounding to that is also what is being observed within the family, especially if living in the same house.

A

Genetic theories

45
Q

Peak blood concentration of alcohol is reached in

A

30 to 90 minutes and usually in 45 to 60 minutes (depends on with/without food)
○ It depends on whether or not you have eaten
○ If you have eaten, it will lower the absorption; if on empty stomach, much is absorbed.
○ Most patients do not eat well during drinking because the focus now is on the alcohol, they don’t crave for
food

46
Q

Rapid drinking

A

Reduce time to peak conc

47
Q

Slow drinking

A

Increase time to peak conc

48
Q

Why do you experience nausea and vomiting when drinking?

A

Pylerospasm

49
Q

Absorption of alcohol is most rapid w beverages containing

A

15-30% alcohol (30-60 proof)

50
Q

When alcohol in stomach becomes

A

too high, mucus is secreted and the pyloric valve closes

51
Q

90% of alcohol absorbed is metabolized thru oxidation in the

A

Liver

52
Q

The remaining 10% is excreted unchanged by the

A

Kidneys and lungs

53
Q

Body can metabolize

A

15 mg/dL per hour, with, a range of 10 to 34 mg/dL per hour

54
Q

In persons w hx of excessive alc consumption,

A

upregulation of the necessary enzymes results in rapid alcohol metabolism

55
Q

catalyzes the conversion of alcohol into acetoaldehyde (toxic compound)

A

Alcohol dehydrogenase (ADH)

56
Q

catalyzes the conversion of acetyldehvde into acetic acid is inhibited by disulferam (Antabuse)

A

Aldehyde dehydrogenase

57
Q

Alcohol biochemistry

A

● About 10% of consumed alcohol is absorbed from the
no single molecular target has been identified as the mediator for the effects of alcohol

● Specifically, studies have found that alcohol ion channel activities associated with the nicotinic acetylcholine, serotonin 5- hydroxytryptamine3 (5-HT3), and GABA type A (GABAa) receptors are enhanced by alcohol

● whereas ion channel activities associated with glutamate receptors and voltage-gated calcium channels are inhibited

58
Q

Blood alcohol levels

A

○ 0.05% - thought, judgment and restraint are loosened and sometimes disrupted
○ 0.1% - voluntary motor actions usually become perceptibly clumsy
○ 0.2% - the function of the entire motor area of the brain is measurably depressed, and the parts of the brain that control emotional behavior are affected
○ 0.3% - a person is commonly confused of may become stuporous
○ 0.4% to 0.5% - the person falls into coma
○ At higher levels, the primitive centers of the brain that
control breathing and heart rate are affected, and death ensues secondary to direct respiratory depression or the aspiration of vomitus

59
Q

Alcohol sleep effects

A

● Alcohol consumed in the evening usually increases the ease of falling asleep (decreased sleep latency)
● Alcohol also has adverse effects on sleep architecture
● Specifically, alcohol use is associated with a decrease in
REM or dream sleep and deep sleep (stage 4) and more sleep fragmentation with more and longer episodes of awakening.
● Therefore, the idea that drinking alcohol helps persons fall asleep is a myth

60
Q

GI system physiological effects of alcohol

A

● Long-term heavy drinking:
○ Esophagitis
○ Gastritis
○ Achlorhydria
○ Gastric ulcers
● Heavy alcohol abuse
○ Esophageal varices (rupture is a medical emergency)
○ Disorders of the small intestine
○ Pancreatitis, pancreatic insufficiency and pancreatic
CA
○ Interfere with normal processes of food digestion and
absorption
● Alcohol abuse also appears to inhibit the intestine’s
capacity to absorb nutrients, such as vitamins and amino acids . (vitamin deficiencies - B vitamins)

61
Q

Physiological effects of alcohol on other bodily systems

A

● Increased blood pressure
● Dysregulation of lipo-protein and triglyceride metabolism
● Increased risk for myocardial infarction and
cerebrovascular disease
● Alcohol has been shown to affect the hearts of nonalcoholic
persons by increasing the cardiac output, heart rate and
myocardial oxygen consumption
● Evidence indicates that alcohol intake can adversely affect
the hematopoietic system, the incidence of cancer, particularly head, neck, esophageal, stomach, hepatic, colon and lung cancer
● Acute intoxication may also be associated with hypoglycemia
● Muscle weakness is another side effect of alcoholism
● Raises the blood concentration of estradiol in women. The increase in estradiol correlates with the blood alcohol level
