What monitoring is recommended during treatment of agitated patients?

• A. Cardiac/ETCO2 monitoring
• B. Glucose monitoring
• C. Only SpO2
• D. Blood cultures

Answer: (A)

During treatment of agitated patients, continuously monitoring both heart rhythm and ventilation is essential because sedatives or the agitation itself can lead to respiratory depression and cardiac events. Cardiac monitoring helps detect arrhythmias or electrolyte-related rhythm changes that could be triggered or worsened by medications used to calm the patient. End-tidal CO2 monitoring provides real-time insight into ventilation status, catching hypoventilation or apnea early even when oxygen levels seem adequate. Relying on SpO2 alone can miss dangerous ventilation problems because oxygen saturation can remain normal until late in a deteriorating respiratory event.

Glucose checks are important as part of broad assessment to rule out hypo- or hyperglycemia as a cause of agitation, but they don’t offer continuous information about ventilation or cardiac rhythm during treatment. Blood cultures aren’t relevant to the immediate monitoring needs of an agitated patient. So, combining cardiac monitoring with ETCO2 monitoring delivers the most comprehensive safety during management.
