What potential complication should a nurse monitor for in an older adult who abruptly stops consuming alcohol after heavy use?

Rationale: A. While alcohol withdrawal can cause mild to moderate increases in blood pressure, severe hypertension is not the primary complication. Blood pressure changes are usually monitored as part of overall withdrawal management but are not the most dangerous risk. B. Respiratory depression is typically associated with opioid or sedative overdose, not alcohol withdrawal. Alcohol withdrawal generally causes hyperactivity of the central nervous system, not depression. C. Delirium tremens is the most severe and life-threatening complication of alcohol withdrawal, especially in older adults with a history of heavy use. DTs can develop 48–72 hours after the last drink and are characterized by severe agitation, confusion, hallucinations, tremors, autonomic instability (tachycardia, hypertension, fever), and potential seizures. Older adults are at higher risk for complications and mortality, making close monitoring and medical intervention critical. D. While chronic alcohol use can contribute to nutritional deficiencies and hypoglycemia, abrupt cessation does not typically cause acute hypoglycemia. It is a secondary concern, not the primary life-threatening complication.
