What is one common symptom of contact dermatitis?

1. Redness and itching of the skin

2. Dryness and flaking

3. Rash and blistering

4. Burning and swelling

The correct answer is: Redness and itching of the skin

A common symptom of contact dermatitis is redness and itching of the skin. This condition arises when the skin comes into contact with an irritant or allergen, leading to inflammation. The initial response typically includes localized redness due to increased blood flow to the affected area as part of the body's immune reaction. Itching is also prevalent because the release of histamines and other inflammatory mediators signal the nerves in the skin, prompting a sensation that often leads to scratching. While symptoms like dryness and flaking, rash and blistering, and burning and swelling can occur with contact dermatitis, they may not be as immediate or universally present as redness and itching, which represent the body’s primary responses to the irritant. Understanding these core symptoms is crucial for recognizing and managing contact dermatitis effectively.
