What should an MA-C do if they observe signs of an allergic reaction?

When an MA-C observes signs of an allergic reaction, the most appropriate course of action is to notify a licensed nurse immediately. This is crucial because allergic reactions can escalate quickly, potentially leading to severe complications such as anaphylaxis. The licensed nurse has the training and authority to assess the situation, determine the severity of the reaction, and initiate appropriate medical interventions.

In cases of allergic reactions, it's essential to address them quickly and effectively. While administering an antihistamine might seem like a reasonable option, it should only be done under the instruction of a licensed nurse or physician. Ignoring the signs and continuing to administer medication would put the patient at risk, as it could exacerbate their condition. Similarly, waiting to see if symptoms worsen is dangerous and could lead to negative outcomes, as time is often a critical factor in managing allergic reactions. Therefore, promptly notifying a licensed nurse is the best and safest action to ensure the patient's health and safety.
