Which of the following drugs is NOT authorized for administration by Licensed EMRs in BC?

The correct choice is acetaminophen because, in British Columbia, it is not within the scope of practice for licensed Emergency Medical Responders (EMRs) to administer this medication. EMRs are trained to handle medical emergencies and provide certain interventions, but the administration of medications is typically limited to those that have established protocols and guidelines for emergency situations.

Oxygen, salbutamol, and insulin are included in the list of medications that EMRs are authorized to give under specific circumstances. Oxygen is widely used to treat hypoxia or respiratory distress, salbutamol is an emergency bronchodilator for asthma or other respiratory conditions, and insulin may be administered in situations such as a suspected diabetic emergency. However, the administration of acetaminophen falls outside of the standard practices for EMRs due to the potential complications and specific needs for monitoring that come with its use. Thus, acetaminophen is the only drug listed that cannot be administered by licensed EMRs in BC.
