Psychiatric Nursing: Substance-Related Disorders/ Addictive Disorders
Focus topic: Psychiatric Nursing
Definition: Substance dependence includes any process by which an individual ingests any mind-altering, non prescribed chemical that produces physiological and/or psychological dependence. Withdrawal symptoms are usually manifested when the substance is not taken.
A. Psychological dependence: emotional dependence, desire, or compulsion to continue taking the substance or drug to experience “normal” functioning.
B. Tolerance: the need for greatly increased amounts of the substance to achieve the desired effect.
C. Physiological dependence: physical need for the substance manifested by appearance of withdrawal symptoms when the substance is withheld.
D. Withdrawal from substance causes substance specific syndrome leads to impairment in areas of functioning.
Psychiatric Nursing: Alcohol Abuse
Focus topic: Psychiatric Nursing
Definition: The abuse of any alcoholic substance combined with physical and psychological addiction.
A. Alcohol consumption is permitted by law and supported by most people in our society as a recreational activity.
B. A fine line exists between the social drinker and the addicted or problem drinker.
C. The greatest difference involves the degree of compulsion to drink and the inability to survive the trials of everyday living without the ingestion of alcohol.
D. An estimated 17 million Americans have alcohol use disorders including alcoholism and harmful drinking that does not reach the level of dependence.
E. Alcoholism is involved in thousands of deaths and injuries (auto accidents) every year.
F. The legal definition of intoxication in most states is 0.10% or higher blood alcohol level (in California, it is 0.08%).
G. Alcoholism decreases life span 10 to 12 years.
H. Suicide accounts for a significant percentage of deaths among alcoholics.
I. Loss to industry caused by alcoholism is estimated at $15 billion a year (affecting primarily the 35-to-55 age group) and overall costs of alcohol-related problems is estimated to be over $70 billion per year.
J. Major U.S. social concern is the dramatic rise in teenage alcoholism (estimated to affect 3 million adolescents).
Dynamics of Alcoholism
A. Alcoholic disease implies the consumption of alcohol to the point where it interferes with the individual’s physical, emotional, and social functioning.
- The syndrome consists of two phases: problem drinking and alcohol addiction.
- Dependence on other drugs is very common.
B. A genetic or familial predisposition to dependence may exist. Genetically determined genes determine the type of dependence an individual may develop.
- Genetic influences are the same for both men and women.
- Children of alcoholics have a four times higher risk of becoming alcoholic.
C. Alcohol blocks synaptic transmission, depresses the central nervous system (CNS), and releases inhibitions. It acts initially as a stimulant but is actually a depressant.
- Chronic excessive use can lead to brain damage.
- High blood levels may cause malfunctions in cardiovascular and respiratory systems.
D. Psychological effects of alcohol appear to be the gratification of oral impulses and the reduction of superego forces; abuse leads to shame and guilt and impaired ego formation.
E. Alcohol may be said to be a defense against overwhelming psychological needs and conflicts; therefore, the client needs to work on problems causing his or her distress.
F. Illnesses associated with chronic alcoholism.
- Wernicke-Korsakoff ’s syndrome (related to thiamine deficiency).
- Delirium tremens.
- Gastritis, esophagitis, and pancreatitis.

Psychiatric Nursing: Substance Dependence
Focus topic: Psychiatric Nursing
Definition: Substance dependence is a state of dependency on drugs other than alcohol or tobacco that involves alteration of perception or mood and is produced by repeated consumption of the drug, causing tolerance to the substance and withdrawal symptoms. Withdrawal may range from discomfort to life threatening. Many individuals mix substances. It is important to identify if there is multiple drug use as well as consumption of alcohol, which increases risk for overdose and death.

- Emotional dependence on the drug (to alter mood) occurs first, followed by physical dependence on the drug.
- Opioids (narcotics) have a sedative or depressant effect on the CNS.
- Tolerance level increases, so greater amounts of the drug are necessary to produce desired effects.
- Addiction tends to be chronic, with a high rate of relapse.
- Withdrawal symptoms.
b. Nausea and vomiting.
c. Sneezing, yawning, watery eyes, and runny nose.
d. Tremor and profuse perspiration.
e. Stomach cramps, muscle aches, and dehydration.
B. Sedative–hypnotics, anxiolytics–barbiturate addiction.

- CNS depressants danger of death from overdose and withdrawal. They are often implicated in suicide attempts.
- Psychological dependence occurs, followed by tolerance and physical dependence.
- Drug may have been prescribed for relief of chronic pain, anxiety, or sleeplessness.
- Withdrawal may result in delirium, seizures, and death.
- Overdoses and acute withdrawal are medical emergencies and require hospitalization. Onset of withdrawal symptoms depends on a number of factors including half-life of the substance used.
C. Amphetamines—Benzedrine and Dexedrine.
- All produce a “high.”
- All are CNS stimulants, so overuse may result in brain damage, mental status changes, capillary bleeding, cardiac changes, and death.
- Large doses produce a hyperactive and agitated state.
- Amphetamines are emotionally addictive, especially for persons who harbor insecurities,
- Amphetamines affect individual’s physical condition as the drug reduces appetite and awareness of body needs.
D. Lysergic acid diethylamide (LSD)—“acid.”
- LSD is a hallucinogenic drug and mimics hallucinations seen in psychoses.
- LSD produces changes in perception and logical thought processes.
- Drug not considered addictive perse, but individuals may become emotionally dependent on it.
- Experiences with LSD range from ecstasy to terror, and the results are unpredictable.
E. Cannabis (marijuana).
- Marijuana was considered to have low abuse potential but now most professionals agree that this is not the case.
- It produces a “dreamy” state and feelings of euphoria, hilarity, and well-being.
- Moods vary according to environmental stimuli.
- Marijuana changes perception of space and time, which seem distorted and extendible.
- High dosage may produce hallucinations and delusions.
- Cocaine is classified as a stimulant.
- Usual method of ingestion is by sniffing, intravenous (IV), or smoking.
- Use may cause strong psychological dependence.
- Physical dependence may occur, especially if used repeatedly.

- The most addictive drug known; a form of hydro chloride cocaine.
- It is smoked in cigarettes or glass water pipes.
- Crack is cheap and quickly addictive because there is a rapid high, then a “downer” that makes the person desire more crack.
- Symptoms include paranoia, depression, and physical symptoms.
H. Phencyclidine (PCP)—“elephant tranquilizer,” “angel dust.”
- PCP may also be ingested, injected, taken intravenously, or sniffed.
- Reactions vary from a sense of well-being to acute anxiety to total disorientation and hallucinations.
- PCP is considered an extremely dangerous “street” drug.
- Psychological dependence may occur.
- Cardinal signs of PCP use are blank stare, ataxia, muscle rigidity, nystagmus, and tendency toward violence.
- Cerebral cellular destruction and atrophy occur with even small amounts.
- Overdoses or “bad trips” are characterized by erratic, unpredictable behavior; withdrawal symptoms; disorientation; self-mutilation; or self-destructive behavior.
- Overdoses are treated with sedatives, decreased environmental stimuli, and protecting client from harming self and others. Cannot be “talked down.”

B. Use of the Clinical Opiate Withdrawal Scale (COWS) is commonly used for assessment of clients withdrawing from opiates. It elicits an aggregate score for heart rate, sweating, restlessness, pupil size, joint and muscle pain, nasal discharge and tearing, GI distress, tremor, yawning, anxiety, and piloerection. Treatment options are determined based on score.
C. Administer medications—e.g., Dolophine (methadone), Buprenex (buprenorphine), and Catapres (clonidine) if ordered, to reduce the physical reaction and complications to withdrawal.
D. Provide other medical and psychiatric treatment if physical and emotional deterioration or complication including alterations in nutrition, gastrointestinal disturbance, seizures, anxiety, and craving.
E. Encourage client to participate in recovery programs by professional or community resources.
F. Provide client with information concerning rehabilitation programs designed to help client reenter the mainstream of society.
