After administering activated charcoal to a patient, what is the most critical observation to make?

• A. Document the intervention.
• B. Monitor the patient's blood pressure.
• C. Be alert for vomiting.
• D. Call medical control.

Answer: (C)

After giving activated charcoal, the most important thing to watch for is vomiting. Vomiting is a red flag because it dramatically raises the risk of aspiration if the patient’s airway isn’t protected. If stomach contents are expelled and the patient isn’t able to clear or protect the airway, charcoal can be inhaled into the lungs, leading to obstruction or chemical pneumonitis. So, continuously observe for nausea or active vomiting, be ready to suction and protect the airway, and reconsider continuing or repeating charcoal if vomiting occurs or the patient cannot protect their airway. Documentation, blood pressure checks, and contacting medical control are important steps, but the immediate priority is preventing aspiration by monitoring for vomiting.
