Clinical Scenario: A 65-year-old patient with suspected COVID-19 develops new onset confusion, restlessness, and agitation.
Immediate Nursing Actions:
- Assess ABCs and Vital Signs: Immediately check airway patency, respiratory rate, work of breathing, oxygen saturation, heart rate, and blood pressure. Hypoxemia is a primary driver of acute confusion in COVID-19.
- Evaluate Neurological Status: Perform a focused neurological assessment using a validated tool like the Confusion Assessment Method (CAM) to confirm delirium. Note the time of onset and any fluctuating course.
- Rule Out Hypoxia: If SpO2 is below target range (typically 92-96% for acute illness), apply supplemental oxygen immediately and titrate to effect. Do not wait for a physician order in an emergency; initiate per protocol and notify provider.
- Ensure Patient Safety: Implement fall precautions, including keeping the bed in the lowest position, using a bed alarm, and providing a sitter or frequent observation. Agitation increases fall risk.
- Notify the Provider: Report the acute change in mental status, current vital signs, and interventions initiated. Prepare for potential orders for arterial blood gas analysis, chest imaging, or transfer to a higher level of care.
Pathophysiology Rationale: Acute cerebral dysfunction in COVID-19 is often linked to reduced regional cerebral oxygen saturation (rSO2). Systemic hypoxemia, combined with the virus's potential neurotropic effects and a hyperinflammatory state, compromises cerebral oxygen delivery, precipitating delirium. This is a medical emergency signaling potential multi-organ decompensation.
