What is the priority action if a patient shows signs of an allergic reaction to a medication?

The priority action when a patient shows signs of an allergic reaction to a medication is to notify the healthcare provider and provide supportive care. Recognizing an allergic reaction is crucial, as it can lead to serious complications, including anaphylaxis, which can be life-threatening.

By notifying the healthcare provider, you ensure that the patient receives appropriate medical intervention, which may include the administration of antihistamines, corticosteroids, or epinephrine, depending on the severity of the reaction. Providing supportive care is also essential, as it involves monitoring the patient’s vital signs, ensuring their safety, and managing symptoms to alleviate discomfort until further treatment can be provided.

This course of action prioritizes the patient's safety and health by facilitating prompt medical response and care. Other responses, such as continuing the medication, reassuring the patient without actionable steps, or suggesting alternatives without professional guidance, do not adequately address the serious nature of an allergic reaction and may put the patient at greater risk.
