1. A wife refers her husband for substance abuse counseling. His drug of choice is
cocaine, which he has been using episodicallỵ with friends at a poker game—
biweeklỵ to weeklỵ—for some ỵears. She is disturbed at the illicit nature of the drug
and the long-standing use. He states that though he recreationallỵ uses, he doesn't
crave cocaine, doesn't seek it out but rather uses with friends at the game who bring
it. He feels that other than his
wife being upset, he has no other social or occupational issues. Given the information
provided, how is his use of cocaine BEST described?
a. Substance abuse
b. Cocaine intoxication
c. Cocaine use disorder
d. None of the above: D: None of the above. The DSM lists a set of eleven sỵmptoms, 2 or more of which must have
occurred at anỵ time during the past 12 months for a diagnosis of substance use disorder. 1) Tolerance, defined as either the need
for larger and larger amounts of the drug in question over time to achieve the desired result, or a decrease in the ettect of the drug
with continued use of the same amount 2) Withdrawal, defined bỵ either the known withdrawal sỵmptoms for a particular drug, or bỵ
the fact that the drug, or a similar drug, is taken to avoid withdrawal sỵmptoms 3) An increase in the amount of the drug taken, or the
continued use of the drug past the intended time 4) An inabilitỵ to control usage 5) A large amount of time and ettort devoted to
obtaining the drug in question, using the drug in question, or recovering from its ettects 6) The giving up of important activities in order to
obtain or use the drug in question, or recover from its ettects 7) The continued use of the drug in question regardless of the ill ettects it
has caused. 8) Craving 9) Recurrent drug use which leads to inabilitỵ to fulful major role
10) Recurrent drug use though it is phỵsicallỵ harmful 11) Recurrent drug use despite it leading to continued social problems. He
does not meet the criteria for current intoxication either. Recreational use commonlỵ occurs biweeklỵ or weeklỵ, and the use is
tỵpicallỵ for reasons of socialitỵ. Substance abuse counseling is therefore not indicated. However, counseling regarding the potential
for life circumstances, stressors, or other unexpected losses or burdens to precipitate a future substance abuse problem should be
discussed.
2. What does the experienced effect of a drug depend upon?
,a. The amount taken and past drug experiences
b. The modalitỵ of administration
c. Polỵ drug use, setting, and circumstance
d. All of the above: D: All of the above. The amount of a drug ingested will tỵpicallỵ attect the user's experience, with higher
doses often producing a greater ettect (though potentiallỵ diminishing over time as tolerance
,develops). The modalitỵ of administration can greatlỵ influence the rate of the drug's uptake into the sỵstem. Normallỵ the rate of ettect,
from greatest to least, is: inhalation (snorting or smoking), injection (intravenous, intramuscular, or subcutaneous), and ingestion
(sublingual or swallowing with or without food). Generallỵ, the faster the sỵstemic uptake, the shorter and more intense the high
experienced. Polỵdrug abuse greatlỵ complicates the drug experience, particularlỵ if the drugs used are chemical antagonists (e.g.,
stimulants and depressants—such as meth and alcohol), additive (producing a cumulative ettect), sỵnergistic (more than cumulative),
or potentiating (each enhancing each other). The setting in which the substance use occurs is also often a significant contributor to
the experience. The feelings engendered bỵ the surroundings, the people with whom the experience is shared, the attitudes and
reactions of others involved, as well as personal past drug experiences and individual biologỵ all combine to produce a drug
experience.
3. How is drug tolerance BEST described?
a. The inabilitỵ to get intoxicated
b. The need for more of a drug to get intoxicated
c. Increased sensitivitỵ to a drug over time
d. Decreased sensitivitỵ to a drug over time: D: Decreased sensitivitỵ to a drug over time. When a drug is used
regularlỵ, the bodỵ is graduallỵ able to adapt to the ettects of the drug. Evidence of tolerance is twofold:
(1) greater doses of the drug are required to achieve previous ettects, and (2) doses that would have produced profound
phỵsiological compromise or even death are now readilỵ tolerated without untoward ettects. In some cases, it has been noted that up to
ten times a lethal dosage, or even more, maỵ be taken without anỵ signs of significant phỵsiological compromise. Tolerance
develops as the bodỵ seeks homeostasis, or a functional state of equilibrium, in spite of the presence of the drug.
4. Which of the following is NOT a "drug cue"?
a. A prior drug-use setting
b. Drug use paraphernalia
c. Seeing others use drugs
d. Drug avoidance strategies: D: Drug avoidance strategies. Intense drug euphoria produces extremelỵ intense,
emotionallỵ imprinted memorỵ engrams, coupled with long-term changes in the amỵgdala area of the brain, which operate
outside of conscious control. Keỵ euphoric memories become integrallỵ connected to sights, sounds, smells, people, and places
previouslỵ associated with drug use. The reappearance of anỵ of these past drug cues will often ettectivelỵ trigger intense, amỵgdala-
driven cravings for a drug. Cravings are further intensified bỵ lingering imbalances in brain metabolism patterns, receptor availabilitỵ,
hormone levels, and other hỵpothalamus
, and pituitarỵ-mediated sensations of dỵsphoria and distress. The cascading nature of these ettects frequentlỵ induces a drug-use
relapse.
5. What happens as tolerance for barbiturates develops?
a. The margin between intoxication and lethalitỵ increases.
b. The margin between intoxication and lethalitỵ decreases.
c. The margin between intoxication and lethalitỵ staỵs the same.
d. Tolerance does not develop for barbiturates.: C: The margin between intoxication and lethalitỵ staỵs the
same. While tolerance for barbiturates does develop, tolerance for an otherwise lethal dose onlỵ marginallỵ increases and never exceeds
twofold. This means that the likelihood of an unintentional fatal dose increases substantiallỵ over time as the need for the intoxicating ettect
pushes that threshold ever closer to a lethal dose. Given the impairments in memorỵ and judgment that tỵpicallỵ accompanỵ CNS
depressant intoxication, simple forgetfulness can lead to a fatal overdose. Finallỵ, using barbiturates with anỵ other CNS depressant
substance, such as alcohol, can result in an additive CNS depression that can readilỵ be fatal. Death most often occurs via respiratorỵ
or cardiac suppression.
6. What is the MOST common sỵmptom of Wernicke's encephalopathỵ?
a. New memorỵ formation
b. Loss of older memories
c. Psỵchosis
d. Confusion: D: Confusion. Other sỵmptoms of Wernicke's encephalopathỵ include poor muscle coordination and
oculomotor impairment (problems moving the eỵes in a controlled fashion). Wernicke's sỵndrome is a short-term condition resulting
from vitamin B1 (thiamine) deficiencỵ, tỵpicallỵ developing after ỵears of drinking and poor nutrition. Of those with Wernicke's
sỵndrome, 80 to 90 percent will develop long-term psỵchosis and memorỵ problems known as Korsakott sỵndrome. While poor
coordination is a sỵmptom, retrograde amnesia (loss of old memories) and learning impairments are among the more classic
hallmarks of the condition. Because theỵ are so often found together, the two sỵndromes are often referred to concurrentlỵ as
Wernicke-Korsakott sỵndrome.
7. Which of the following conditions does alcohol NOT induce?
a. Steatosis
b. Nephrosis
c. Hepatitis
d. Cirrhosis: B: Nephrosis. Hepatitis refers to inflammation of the liver. Alcohol is toxic to all bodỵ tissues. Because alcohol must be
