Withdrawal Risk During Acute Alcohol Detoxification
Mr. Brennan, 46, is admitted to a medical unit for cellulitis. He discloses drinking 'about a pint of whiskey daily' for years and had his last drink 10 hours ago. Vital signs: BP 158/96 mmHg, HR 112/min, RR 22/min, temperature 37.6 C. He is tremulous, diaphoretic, and reports feeling anxious. He is oriented to person, place, and time. His CIWA-Ar score is 14. The provider's orders include lorazepam 2 mg IV every 4 hours as needed for CIWA-Ar 8-15, and vital signs every 8 hours.
1. Interpret his presentation and explain why it matters for the plan of care.

His tremor, diaphoresis, anxiety, tachycardia, and hypertension 10 hours after his last drink are consistent with alcohol withdrawal syndrome, which can progress to seizures (typically 12-48 hours) and delirium tremens (48-96 hours). A CIWA-Ar of 14 is in the moderate range and warrants treatment.
Reasoning: Withdrawal is progressive and time-linked to the last drink. The nurse must anticipate worsening, not just treat the current score, and recognize that medical admission for another problem does not remove withdrawal risk.
2. The order is vital signs every 8 hours and lorazepam PRN with CIWA-Ar 8-15. What is the flaw and how should the nurse respond?
Read the worked answer
Flaws: (1) Vital signs every 8 hours are too infrequent for an actively withdrawing patient; (2) CIWA-Ar should be assessed more often than every 8 hours (typically hourly or per protocol) to catch deterioration; (3) PRN dosing based on symptom scores requires frequent scoring to be safe.
Nurse's response: Increase monitoring frequency based on clinical judgment, document assessments, notify the provider for revised orders (e.g., hourly CIWA-Ar and vital signs), administer lorazepam per the ordered threshold, and monitor for over-sedation (RR, sedation scale).
Reasoning: The nurse is accountable for recognizing that the monitoring plan does not match the patient's risk and for escalating.
3. Four hours later he is confused, hallucinating, with HR 130/min and BP 170/100 mmHg. What is happening and what are the priorities?
Read the worked answer
This is delirium tremens - a medical emergency with significant mortality if untreated. Priorities:
- Stay with the patient and call for help; ensure safety (fall precautions, reduce stimulation).
- Notify the provider immediately; anticipate benzodiazepine dosing, IV fluids, and possible ICU transfer.
- Monitor vital signs, oxygenation, and glucose.
- Reorient calmly and avoid restraints unless necessary for safety.
Reasoning: The shift from moderate withdrawal to confusion with autonomic hyperactivity is a red flag. Recognition and rapid escalation, not just giving the PRN and waiting, determines outcome.
