76 76 Thought Disorders Schizophrenia: Interventions Establish & maintain safe environment Establish trust Manage delusions Focus on feelings versus delusions Engage in reality testing Validate functional behaviors Anxiety management Stress reduction strategies

77 77 The major advantage of the newer atypical antipsychotics over older phenothiazines and high potency antipsychotic medication is: A. Less chance for agranulocytosis B. Availability as a long-lasting injection C. Absence of EPS D. Resolution of positive and negative symptoms

78 78 A patient with schizophrenia tells you that voices in his head are telling him he is in danger, and that he must stay in his room. He asks you, "Do you hear them?" Your best therapeutic response would be: A. “I know these voices are very real to you, but I don't hear them.” B. “You need to get out of your room and get your mind occupied so you don't hear the voices." C. “Don't worry. You're safe in the hospital. I won't let anything happen to you.” D. “The voices are coming from your imagination.”

79 79 Substance Abuse/Dependence Incidence Alcohol dependence/abuse 14% Drug dependence 3% Co-morbidity common Defense Mechanisms Rationalization, projection, denial CNS depressants Alcohol, benzodiazapines, barbituates

80 80 Substance Abuse  Maladaptive, recurring use of substance accompanied by repeated detrimental effects of drug  Present for one year or more  Episodic binges  Can occur without dependency  Encounters with law, school suspension, family/marital problems

81 81 Maladaptive, reversible pattern of behavior  Perceptual disturbances  Sleep—wake cycle changes  Disturbs attention, concentration, thinking, judgment, psychomotor activity  Interferes with relationships Substance Intoxication

82 82 Substance Dependence Craving – strong inner drive to use substance - unsuccessful efforts to control use Tolerance – decreased effectiveness of drug over time with need for increased doses of substance to achieve same effect Withdrawal – unpleasant, maladaptive changes in behavior as blood/tissue concentrations of substance decline after prolonged heavy use Much time used in obtaining substance Activities given up in lieu of substance use Continued use in spite of negative problems from usage

83 83 Larger amounts over longer time period than intended Persistent desire/unsuccessful efforts to control use Much time used in obtaining substance Activities given up in lieu of substance use Continued use in spite of negative problems from usage Substance Dependence

84 84 PHASES Phase 1 Mood swings, altered emotional state Phase 2 Hangover effects, guilt about behavior Phase 3 Dependent lifestyle, control over substance is lost Phase 4 Dependency, addiction, blackouts, paranoia, helplessness Substance Dependence

85 85 Substance Abuse/Dependence Possible long-term effects of chronic alcohol abuse  Gastritis  Esophagitis  Acute or chronic pancreatitis  Cirrhosis  Cardiac problems  Neurological problems  Wernicke-Korsakoff’s syndrome  Osteoporosis and myopathy

86 86 Alcohol Withdrawal Accompanied by physiologic/cognitive symptoms from reduction in prolonged substance use  Early Signs  Develop within few hours after cessation/peak at 24-48 hours  Anxiety, anorexia, insomnia, tremors, hyperactivity, irritability, “shaking inside,” hallucinations, illusions, nausea/vomiting, Increased Temp, pulse, and BP  Delirium Tremens (DTs)  Peak in 48-72 hours after cessation of drinking – last 2-3 days  20% fatality rate

87 87 Nursing Interventions: Alcohol Dependence  Medication – sedation  High protein, high vitamin diet (B/C)  Replace fluid/ electrolytes (I/O) Diuresis with blood alcohol level increase Fluid retention may occur (overhydration)  MgSO4 to increase body’s response to thiamine/raise seizure threshold  VS q hour x 12 h, then q4h Pulse good indicator of progress through withdrawal

88 88 Vitamin B1 Deficiency  Vitamin B1 (Thiamine) and niacin deficiency  Encephalopathy and psychosis primarily in alcoholics caused by thiamine deficiency, due to poor dietary intake and malabsorption (Wernicke- Korsakoff Syndrome)  Permanent progressive cognitive loss

89 89 Substance Dependence: Alcohol Maintaining abstinence Antidepressents - SSRIs and Buspirone (BuSpar) Naltrexone (ReVia), Nalmefene (Revex) -opioid antagonists that help with alcohol dependence - reduces cravings and increases abstinence Disulfiram (Antabuse) - Treat alcoholism. Inhibits aldehyde dehydrogenase, if alcohol ingested, causes facial flushing, tachycardia, decreased BP, nausea, vomiting, SOB, seating dizziness and confusion

90 90 Substance Dependence: Alcohol Relapse prevention Accept as a chronic disease Self-help groups, AA Stress management Family support

91 91 Substance Abuse/Dependence Narcotic opiates commonly abused Heroin, Demerol, Dilaudid, Oxycontin Treatment Recognition of drug seeking Manage intoxication/overdose Opioid withdrawal: Naltrexone (ReVia), Buprenophine (Buprenex), Dolophine (Methadone) Self-help groups, Narcotics Anonymous (NA) Relapse prevention

93 93 Substance Abuse/Dependence Reasons nurses are at high risk for substance use.  Nurses see medication as solutions to problems  Access to drugs at work  Access to physicians who prescribe drugs  Compassion fatigue: Pressure and emotional pain felt at work  Anger and frustration nurses feel at work  Emotions felt at work respond to drugs– short term

94 94 Substance Abuse/Dependence Signs of substance abuse in nurses  Change in nurse’s behavior  Mood changes, irritability, isolation  Change in work performance  Multiple medication errors, missed deadlines, poor judgment, absenteeism  Signs of drug use or withdrawal  Red eyes, ataxia, anxiety, use of breath mints and perfume, slurred speech

95 95 Substance Abuse/Dependence Action plan if you suspect a peer Report the peer suspected of drug abuse to a manager or supervisor to:  Protect the clients from harm  Protect the peer from harming clients or self  Get diagnosis and treatment for impaired peers
