Which hypothesis is the nurse addressing when the patient is assessed for urticaria, itching, and rash after administration of a medication?

The nurse is addressing the hypothesis of risk for allergic reaction when assessing the patient for urticaria, itching, and rash following medication administration. Urticaria, commonly known as hives, and associated itching and rash are classic symptoms of an allergic response to a medication. When a medication is introduced into the body, it can trigger an immune system response in susceptible individuals, leading to these specific dermatological symptoms. Recognizing these signs is crucial for the nurse, as they indicate a potential allergic reaction, which may require prompt intervention to prevent further complications.

In this context, assessing for an allergic reaction is important for patient safety and to facilitate appropriate treatment measures. Understanding these symptoms helps the clinician determine the best course of action, including possible medication modifications or additional therapies to alleviate the allergic symptoms.
