Early withdrawal (6-24 hours) brings tremors, anxiety, nausea, diaphoresis, and elevated vital signs.

Test yourself first: 5 questions
Question 1 of 5
Which class of medication is the standard first-line treatment to prevent seizures and reduce symptoms during alcohol withdrawal?
Answer: A. Benzodiazepines (such as lorazepam, chlordiazepoxide, or diazepam) are the first-line agents for alcohol withdrawal because they have cross-tolerance with alcohol at the GABA receptor, preventing seizures and delirium tremens. Antipsychotics lower the seizure threshold, opioids treat pain not withdrawal, and beta-blockers may mask symptoms without preventing seizures.
Question 2 of 5
A client is admitted with acute alcohol withdrawal 8 hours after the last drink. Which finding is the priority for the nurse to report and treat?
Answer: B. Seizures and severe autonomic hyperactivity are the dangerous complications of alcohol withdrawal. A heart rate of 124 with tremors and agitation signals escalating withdrawal that needs prompt benzodiazepine treatment. Mild anxiety, a single episode of nausea, and a craving for a cigarette are expected and lower priority.
Question 3 of 5
A client who chronically uses benzodiazepines abruptly stops taking them. The nurse recognizes that abrupt benzodiazepine withdrawal can be life-threatening because of which complication?
Answer: A. Like alcohol, benzodiazepines act on the GABA system, and abrupt cessation after chronic use can cause severe withdrawal including seizures, which can be fatal. Benzodiazepines must be tapered, not stopped abruptly. Hyperglycemia, hypothermia, and bradycardia are not the hallmark life-threatening features of benzodiazepine withdrawal.
Question 4 of 5
A client with chronic alcohol use disorder has the following labs. Which finding is most consistent with chronic heavy alcohol use and warrants follow-up?
Answer: A. Chronic heavy alcohol use commonly elevates liver enzymes, especially gamma-glutamyl transferase (GGT) and AST, and causes macrocytic anemia with an elevated MCV from folate and B12 effects. An elevated GGT with an AST greater than ALT is a classic pattern. A normal mean corpuscular volume, a normal albumin, and a low potassium alone are less specific to alcohol-related liver effects, though electrolytes do need correction.
Question 5 of 5
A client receiving chemotherapy reports painful mouth sores. On inspection, the nurse notes erythema and ulcerations of the oral mucosa. Which intervention is most appropriate for this client's stomatitis?
Answer: A. Chemotherapy-induced mucositis is managed with frequent gentle oral care using a soft toothbrush and a bland, alcohol-free rinse such as saline or sodium bicarbonate solution. Commercial alcohol-based mouthwashes, lemon-glycerin swabs, and hot, spicy foods irritate and dry the mucosa and worsen the condition.
Keep the streak going with more questions like these, each with a full rationale.
What is alcohol withdrawal (dts)?
Symptoms begin within 6 to 24 hours; delirium tremens (DTs) is the most severe form, peaking around 48 to 72 hours, and can be fatal. Benzodiazepines are the treatment of choice and the CIWA scale guides dosing.
Key points to remember
- Early withdrawal (6-24 hours) brings tremors, anxiety, nausea, diaphoresis, and elevated vital signs.
- Withdrawal seizures typically occur within 12 to 48 hours.
- Delirium tremens (48-72 hours) features severe confusion, agitation, hallucinations, fever, and autonomic instability.
- DTs carry significant mortality risk if untreated.
- Thiamine deficiency can cause Wernicke encephalopathy; give thiamine before glucose.
- Benzodiazepines are tapered to control CNS hyperactivity and prevent seizures.
Signs & symptoms
- Tremors, anxiety, ↑ HR/BP
- Sweating, N/V, insomnia 6–24h
- DTs: confusion, hallucinations, fever
Nursing priorities
- Assess withdrawal severity using the CIWA-Ar scale and monitor vital signs frequently.
- Administer scheduled or symptom-triggered benzodiazepines per protocol.
- Give thiamine, folate, and multivitamins; administer thiamine before any glucose.
- Provide a calm, quiet, well-lit environment and institute seizure and fall precautions.
- Maintain hydration and correct electrolyte imbalances such as magnesium.
Labs & values
Patient teaching
- Withdrawal can be dangerous; medically supervised detox is essential, never quit alone if dependent.
- Take thiamine and vitamins as prescribed to prevent brain complications.
- Connect with support programs and avoid all alcohol after detox.
Red flags: report now
- Delirium tremens with hyperthermia, severe tachycardia, and hypertension is a medical emergency.
- Withdrawal seizures require immediate intervention and seizure precautions.
- Giving glucose before thiamine can precipitate Wernicke encephalopathy.
- Rapidly rising vital signs and worsening confusion signal escalating, potentially fatal withdrawal.
