Which of the following are symptoms of Poison Ivy or Oak exposure?

The symptoms of Poison Ivy or Oak exposure predominantly include itchiness, burning rash, skin inflammation, and infected blistering. These plants contain an oil called urushiol, which is responsible for triggering allergic reactions in many people upon contact. When the skin comes into contact with urushiol, it can lead to a localized allergic reaction characterized by intense itching and a rash, which can develop blisters that may become infected if scratched.

While other symptoms such as shortness of breath might occur in severe cases or due to secondary reactions (like anaphylaxis), they are not typical for most cases of Poison Ivy or Oak exposure. Likewise, dizziness, headaches, nausea, and fever are not directly associated with contact dermatitis resulting from these plants. Therefore, the symptom cluster mentioned relates most clearly to the direct effects of urushiol on the skin, making it the correct choice in this context.
