What is the primary concern for a client experiencing severe itching due to poison ivy exposure?

The primary concern for a client experiencing severe itching due to poison ivy exposure is the potential for a severe allergic reaction. Poison ivy contains an oil called urushiol, which triggers an immune response in sensitive individuals. This exposure can lead to an allergic contact dermatitis characterized by severe itching, redness, and swelling.

In some cases, the reaction can escalate, leading to complications such as widespread rashes, blistering, and secondary infections due to scratching. It's essential to monitor for signs of anaphylaxis, though it is rare with poison ivy, as well as more severe symptoms or complications arising from the allergic reaction.

This focus on the allergic response is crucial, as prompt management of symptoms and avoidance of further contact can significantly affect the client's comfort and prevent severe outcomes. Understanding the nature of the allergy informs appropriate treatment, such as the use of antihistamines, topical corticosteroids, or other interventions to alleviate the symptoms effectively.
