Accepted Answer

Treatment of amphetamine intoxication is aimed at supporting vital functions and providing symptomatic therapy. Acidifying the urine will increase excretion. Adrenergic blockers and vasodilators can be administered to control excessive sympathetic and cardiovascular stimulation. Diazepam is generally preferred to control seizures and also can be used for sedation when necessary.

Question 3

Cross-tolerance has been found to exist within which group of commonly abused drugs?&#10;A) Marijuana&#10;B) Phencyclidine&#10;C) Psychomotor stimulants&#10;D) LSD

Accepted Answer

Also, a cross-tolerance exists between LSD and the other drugs of this group, so subsequent doses of one drug taken shortly after another drug produce decreased effects.

Question 4

_____ is an endogenous substance in the brain that is thought to bind to _____ receptors.&#10;A) Anandamide, Kappa&#10;B) Dynorphin, adrenergic&#10;C) Anandamide, CB1&#10;D) Dynorphin, CB2

Accepted Answer

The receptor is referred to as a cannabinoid receptor (CB1). In addition, an endogenous substance, anandamide, has been identified in the brain that is believed to bind to the cannabinoid receptor.

Question 5

The consumption of larger doses of a drug to prevent onset of psychological and physical withdrawal symptoms.&#10;A) Drug tolerance&#10;B) Cross tolerance&#10;C) Drug dependency&#10;D) Drug addiction

Accepted Answer

As drug dependency develops, consumption of larger doses may be necessary to prevent the onset of psychological and physical withdrawal symptoms.

Question 6

Increased amphetamine usage results in behavior very similar to:&#10;A) Hypomania&#10;B) Paranoid schizophrenia&#10;C) Manic depressive personality disorder&#10;D) Neurosis

As amphetamine usage increases and dosages become larger, the psychotomimetic effects become apparent and can lead to psychotic behavior. Amphetamine psychosis is similar to paranoid schizophrenia.

Question 7

Hallucinogenic effects of LSD are thought to result from:&#10;A) Activation of serotonin receptors in the brain&#10;B) Activation of dopamine receptors in the brain&#10;C) Activation of alpha receptors in the brain&#10;D) Activation of beta receptors in the brain

Accepted Answer

Evidence suggests that LSD and the other hallucinogens interact with serotonin receptors in the brain, primarily the 5HT_2A receptors.

Question 8

Drug dependency is more likely to develop in an addict taking _____,because it has a very _____.&#10;A) Cocaine, short duration of action&#10;B) Amphetamines, short duration of action&#10;C) Cocaine, long duration of action&#10;D) Amphetamines, long duration of action

Accepted Answer

However, the duration of action after smoking or injecting cocaine is only 20 to 30 minutes, compared to several hours with amphetamines. Consequently, cocaine must be administered much more frequently in order to maintain the good feelings. This frequency contributes to the reinforcing properties of cocaine on behavior and leads to drug dependency.

Question 9

Treatment for hallucinogenic drug intoxication may include the administration of which medications?&#10;A) Benzodiazepines or opioids&#10;B) Benzodiazepines or barbituates&#10;C) Opioids or barbituates&#10;D) Opioids or muscle relaxers

Accepted Answer

Benzodiazepine antianxiety agents or barbiturates can be used for their sedative effects. This approach to treatment is considered standard therapy for most hallucinogenic drug intoxication.

Question 10

Tricyclic antidepressant drugs have been used in treating cocaine dependency because they:&#10;A) Lessen euphoric effect and minimize tolerance&#10;B) Lessen euphoric effect and reduce cravings&#10;C) Minimize tolerance and reduce cravings&#10;D) Establish a cross tolerance and reduce cravings

Accepted Answer

A newer approach to control cocaine dependency is the use of tricyclic antidepressants (TCAs). Treatment with TCAs has been reported to lessen the euphoric effects of cocaine and to reduce cravings for continued use of the drug.
