Alcohol & Drug Abuse Nursing Quiz Questions

Correct Answer: C. Yawning, cramps, and diarrhea

Rationale: Opioid/heroin withdrawal produces a flu-like syndrome characterized by hyperactivity of the autonomic nervous system. Hallmark signs include excessive yawning, rhinorrhea, lacrimation, piloerection (gooseflesh), severe abdominal cramps, nausea, vomiting, and diarrhea.

• Option A is incorrect: Coma is associated with opioid overdose (triad: coma, pinpoint pupils, respiratory depression), not withdrawal.
• Option B is incorrect: Isolated nausea and fainting (syncope) do not capture the systemic gastrointestinal hypermotility and autonomic discharge typical of opioid abstinence.
• Option D is incorrect: Grand mal seizures and coarse tremors are typical of alcohol or sedative-hypnotic (benzodiazepine/barbiturate) withdrawal, which can be life-threatening.

Correct Answer: C. Thiamine (B1)

Rationale: Alcohol interferes directly with active gastrointestinal transport of thiamine (vitamin B1) and reduces liver storage. Chronic malnutrition combined with alcohol-induced malabsorption leads to severe thiamine depletion.

• Option A is incorrect: Vitamin C deficiency causes scurvy; while malnourished patients may have lower levels, it is not the primary clinical hazard in alcoholism.
• Option B is incorrect: Niacin deficiency leads to pellagra; it can occur in severe malnutrition but is not the signature deficiency governing alcohol management protocols.
• Option D is incorrect: Folate deficiency frequently coexists and causes megaloblastic anemia, but acute neurological devastation is driven primarily by thiamine deficiency.

Correct Answer: B. All of these

Rationale: Central nervous system depressants slow down brain activity, motor coordination, and cognitive reflexes. Cyclobenzaprine (a centrally acting muscle relaxant), cannabis/marijuana (which exerts sedative/depressant effects on the CNS), and ethanol (alcohol) all produce central nervous system depression.

• Options A, C, and D are individually correct, making “All of these” the complete and correct answer.

Correct Answer: B. Wernicke-Korsakoff syndrome

Rationale: Thiamine deficiency impairs neuronal energy metabolism, precipitating acute Wernicke’s encephalopathy (characterized by the triad of confusion, ophthalmoplegia/nystagmus, and ataxia). If untreated, it progresses to Korsakoff’s psychosis (chronic, irreversible anterograde amnesia and confabulation).

• Option A is incorrect: Wolf-Hirschhorn syndrome is a congenital genetic disorder caused by a deletion on the short arm of chromosome 4.
• Option C is incorrect: Lewy body dementia is a neurodegenerative disease linked to abnormal alpha-synuclein protein deposits, not vitamin deficiencies.
• Option D is incorrect: Agnosia is a symptom (inability to interpret sensations or recognize things), not a syndrome caused specifically by nutritional deficiency.

Correct Answer: A. Delirium tremens (DTs)

Rationale: Delirium tremens is the most severe and life-threatening complication of alcohol withdrawal, emerging 48 to 96 hours after the last drink. It carries significant mortality if untreated due to hyperpyrexia, cardiovascular collapse, and profound autonomic instability.

• Options B and C are incorrect: Agitation and tachycardia are common early manifestations of mild-to-moderate withdrawal; while they require clinical monitoring and intervention, they are far less dangerous than full-blown DTs.
• Option D is incorrect: Alcohol withdrawal stimulates sympathetic outflow, leading to tachycardia, not bradycardia.

Correct Answer: A. Alcohol

Rationale: Alcohol remains the most prevalent and legally accessible psychoactive substance abused globally, accounting for significant disease burden, hospital admissions, and socioeconomic morbidity.

• Option B is incorrect: Barbiturate use has declined substantially due to the preferential clinical prescribing of benzodiazepines.
• Option C is incorrect: Heroin is an illicit opioid with lower overall population prevalence compared to alcohol.
• Option D is incorrect: While cannabis (marijuana) is the most widely used illicit drug, alcohol surpasses it in total rates of dependence, abuse, and health burden.

Correct Answer: C. Flushing, vomiting, and dizziness

Rationale: Disulfiram inhibits aldehyde dehydrogenase, blocking ethanol metabolism at the acetaldehyde stage. Acetaldehyde accumulation causes severe facial flushing, throbbing headache, nausea, violent vomiting, diaphoresis, dyspnea, hypotension, and dizziness.

• Option A is incorrect: Isolated cramps and diarrhea are characteristic of opioid withdrawal, not the classic acetaldehyde reaction.
• Option B is incorrect: Drowsiness and respiratory depression reflect sedative-hypnotic overdose, not disulfiram ethanol toxicity.
• Option D is incorrect: While tachycardia occurs, blood pressure characteristically drops (hypotension/vasodilation), which can lead to shock in severe reactions.

Correct Answer: D. Methadone

Rationale: Methadone is a long-acting full mu-opioid receptor agonist used for maintenance therapy. It prevents cravings and withdrawal symptoms without producing the intense rush or euphoria seen with short-acting illicit opioids like heroin.

• Option A is incorrect: Diazepam is a benzodiazepine used to prevent seizures in alcohol withdrawal; it does not substitute for opioid maintenance.
• Option B is incorrect: Carbamazepine is an anticonvulsant used off-label for alcohol withdrawal or neuropathic pain, not opioid substitution.
• Option C is incorrect: Clonidine is a central alpha-2 adrenergic agonist used adjunctively to mitigate autonomic symptoms (hypertension, tachycardia, sweating) during detox, but it is not an opioid substitution therapy.

Correct Answer: D. Sudden death from cardiac or respiratory depression

Rationale: Inhalant abuse carries the risk of “Sudden Sniffing Death Syndrome,” which can occur even in first-time users. Volatile solvents sensitize the myocardium to endogenous catecholamines, triggering lethal ventricular arrhythmias or acute asphyxiation/anoxia.

• Option A is incorrect: Blood-borne pathogens (HIV, Hepatitis B/C) are risks of intravenous drug use, not inhalation.
• Option B is incorrect: Flashbacks (hallucinogen persisting perception disorder) are associated with hallucinogens such as LSD, not inhalants.
• Option C is incorrect: While psychological dependence develops with repeated use, acute fatal cardiorespiratory collapse is the most immediate life threat.

Correct Answer: A. Anxiety, tremors, and tachycardia

Rationale: Benzodiazepines and barbiturates enhance inhibitory GABA neurotransmission. Abrupt discontinuation removes this suppression, producing CNS rebound hyperactivity: severe anxiety, coarse tremors, autonomic arousal (tachycardia, diaphoresis), and potentially fatal seizures.

• Option B is incorrect: Respiratory depression, stupor, and bradycardia are symptoms of acute sedative-hypnotic intoxication or overdose, the opposite of withdrawal.
• Option C is incorrect: Muscle aches, cramps, and lacrimation are symptoms of opioid withdrawal.
• Option D is incorrect: While rebound agitation occurs, paranoia and depression (“crash”) are more characteristic of stimulant withdrawal (e.g., cocaine or amphetamines).

Correct Answer: A. Depressant

Rationale: Opioids act on central mu-opioid receptors to blunt pain perception (analgesia) while depressing overall central nervous system functions, prominently suppressing the respiratory drive, cough reflex, and gastrointestinal motility.

• Option B is incorrect: Hallucinogens alter sensory perception (e.g., LSD, psilocybin, mescaline).
• Option C is incorrect: Stimulants increase synaptic catecholamines and CNS excitation (e.g., cocaine, amphetamines).
• Option D is incorrect: “Tranquilizers” primarily refers to anxiolytics and antipsychotics (neuroleptics) that induce calm without significant analgesia.

Correct Answer: D. Norepinephrine rebound

Rationale: Chronic CNS depressant exposure suppresses sympathetic output. During sudden withdrawal, uninhibited locus coeruleus firing releases massive surges of norepinephrine, producing acute adrenergic storm: hypertension, tachycardia, tremors, and hyperarousal.

• Option A is incorrect: Acetylcholine excess causes cholinergic crisis (SLUDGE syndrome: salivation, lacrimation, urination, defecation, GI upset, emesis), seen in organophosphate poisoning, not depressant withdrawal.
• Option B is incorrect: Dopamine depletion is linked to anhedonia and drug cravings during stimulant withdrawal, but does not drive acute depressant withdrawal physiology.
• Option C is incorrect: Serotonin inhibition is not the primary mechanism behind autonomic hyperactivity in depressant withdrawal.
