## 문제

A nurse is caring for a 52-year-old client admitted 18 hours ago for alcohol detoxification after consuming approximately 12 beers daily for the past 5 years. Which assessment finding requires the most immediate nursing intervention?

## 보기

1. Blood pressure 150/95 mmHg with heart rate 110 bpm and mild anxiety
2. New onset of visual hallucinations with disorientation to time and place **✔ 정답**
3. Tremors of both hands with mild diaphoresis and agitation
4. Nausea and vomiting with decreased appetite and restlessness

**정답: 2**

## 해설

Visual hallucinations with disorientation indicate delirium tremens, a life-threatening complication requiring immediate intervention. Other findings like hypertension, tremors, and nausea are common in withdrawal but less immediately dangerous.

Clinical Priority Analysis

This question tests your ability to recognize the progression of Alcohol Withdrawal Syndrome (AWS) and prioritize care based on the risk of life-threatening complications. The client is within the critical 24- to 72-hour window after cessation of heavy, prolonged alcohol use, which is the peak risk period for severe manifestations. The key to answering this question is differentiating between mild-to-moderate withdrawal symptoms and the onset of delirium tremens (DTs), which constitutes a medical emergency.

Pathophysiology and Clinical Progression

Chronic alcohol consumption enhances the inhibitory effects of gamma-aminobutyric acid (GABA) and suppresses the excitatory effects of glutamate at N-methyl-D-aspartate (NMDA) receptors. When alcohol is abruptly removed, the central nervous system (CNS) loses this depressant effect, resulting in a state of autonomic and neuronal hyperexcitability. This manifests along a predictable continuum of symptoms.

The earliest stage, beginning within 6 to 12 hours, is characterized by minor withdrawal symptoms. These include tremors, mild diaphoresis, nausea, vomiting, anxiety, and autonomic hyperactivity such as hypertension and tachycardia. Options 1, 3, and 4 describe findings consistent with this early, non-life-threatening stage of AWS. While these symptoms require prompt symptom-triggered pharmacotherapy, typically with benzodiazepines, they do not represent the most immediate danger.

The progression to moderate-to-severe withdrawal is marked by the emergence of perceptual disturbances and global confusion. The onset of visual hallucinations with disorientation to time and place, as described in Option 2, is a hallmark of delirium tremens (DTs). This syndrome represents a severe dysregulation of CNS excitability and is a predictor of escalation to a higher level of care. According to the literature, when regular inpatient management fails to control AWS symptoms, patients are shifted to intensive care units (ICUs) for closer monitoring and prevention of life-threatening complications like withdrawal seizures and DTs, a condition labeled as severe alcohol withdrawal syndrome (SAWS) [2]. The presence of DTs signifies a failure of the brain’s homeostatic mechanisms and carries a significant risk of mortality if not treated aggressively and immediately.

Why Other Options Are Less Immediate

The findings in the other options are consistent with early or minor withdrawal and, while requiring intervention, do not signal the same level of immediate threat as DTs.

-   Option 1 (Blood pressure 150/95 mmHg with heart rate 110 bpm and mild anxiety): This represents autonomic hyperactivity, a common and expected finding in early AWS. The blood pressure and heart rate, while elevated, are not at a level that would independently signal an immediate crisis like a hypertensive emergency. The priority is to administer medication to control these symptoms and prevent progression.

-   Option 3 (Tremors of both hands with mild diaphoresis and agitation): These are classic symptoms of minor alcohol withdrawal. Tremors and diaphoresis are due to sympathetic nervous system overdrive. While distressing, they are not immediately life-threatening and are managed with supportive care and pharmacotherapy.

-   Option 4 (Nausea and vomiting with decreased appetite and restlessness): These are common gastrointestinal and psychological symptoms of early withdrawal. They can lead to fluid and electrolyte imbalances if prolonged, but in this acute context, they do not take priority over the rapid neuropsychiatric decline indicated by hallucinations and disorientation.

The Clinical Consensus Document from the American Association for the Surgery of Trauma Critical Care Committee emphasizes the importance of structured screening and monitoring to prevent the progression of AWS in high-risk patients . The development of DTs represents a failure of prevention and requires the most immediate and intensive intervention, including potential transfer to an ICU for airway protection, seizure management, and aggressive sedation [2,3]. The lifetime prevalence of alcohol use disorder is significant, and withdrawal symptoms manifest in approximately 50% of individuals who misuse alcohol, making this a high-frequency clinical scenario . Recognizing the transition from minor symptoms to the perceptual and cognitive disturbances of DTs is the critical nursing judgment being tested here.References (research sources)

Recognizing Delirium Tremens in Alcohol WithdrawalDifferentiating early withdrawal from a medical emergency
The peak risk window for delirium tremens is 24 to 72 hours after the last drink. The hallmark is a change in mental status—new-onset disorientation and visual hallucinations—which distinguishes it from minor withdrawal.

Use a validated tool like the CIWA-Ar scale to assess severity. A score >15 indicates high risk for severe withdrawal. Early symptoms like tremors, diaphoresis, and hypertension are expected but do not constitute an immediate emergency.

CautionDo not wait for all classic DTs signs to appear. Perceptual disturbances with confusion are a medical emergency requiring immediate benzodiazepine administration and ICU transfer to prevent cardiovascular collapse and death.

## 핵심 개념

- **Delirium Tremens** — The most severe form of alcohol withdrawal, typically occurring 48–96 hours after cessation. Characterized by visual/tactile hallucinations, severe disorientation, tremors, agitation, and autonomic instability (fever, tachycardia, hypertension). It is a medical emergency with a high mortality rate if untreated.
- **Alcohol Withdrawal Syndrome** — A group of symptoms that occur when a person with physical dependence on alcohol stops drinking or sharply reduces their intake. Symptoms range from tremors, anxiety, sweating, nausea, tachycardia, and hypertension to hallucinations, seizures, and delirium tremens.
- **CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised)** — A standardized tool for objectively assessing the severity of alcohol withdrawal symptoms. It scores 10 items (nausea/vomiting, tremor, sweating, anxiety, etc.) and is used to determine the need for and dosage of benzodiazepines.
- **Autonomic Hyperactivity** — Excessive activity of the autonomic nervous system. A symptom that occurs when the sympathetic nervous system is overactivated during alcohol withdrawal, including tachycardia, hypertension, sweating, hot flashes, etc.
- **Benzodiazepines** — First-line treatment for alcohol withdrawal symptoms and delirium tremens. It acts on GABA receptors to calm the nervous system, prevent and treat withdrawal symptoms, and reduce the risk of seizures. (e.g., lorazepam, diazepam, chlordiazepoxide).
