What action should be taken if a patient is experiencing an allergic reaction?

If a patient is experiencing an allergic reaction, the appropriate action is to stop the medication, assess the patient, and initiate emergency response. This option is correct because it prioritizes the patient's safety and medical needs. Immediately discontinuing the medication helps to prevent further exposure to the allergen, which could exacerbate the reaction. Assessing the patient allows healthcare providers to evaluate the severity of the reaction, whether it is mild, moderate, or severe, and to determine the appropriate interventions.

Initiating the emergency response is crucial, especially if the allergic reaction progresses to anaphylaxis, which can be life-threatening. Emergency protocols may include administering antihistamines, corticosteroids, or epinephrine, depending on the severity of the reaction.

The other choices do not address the urgency and risk associated with allergic reactions. Continuing the medication while monitoring could worsen the patient's condition. Informing the family, while important, does not provide immediate relief to the patient and does not directly address the medical emergency. Waiting for a doctor's decision can delay necessary treatment, putting the patient at greater risk. Overall, the correct answer emphasizes quick and effective action to ensure the patient's well-being.
