What might cause a rash on the arm in a patient?

• A. Medication allergy
• B. Infection
• C. Genetic disorder
• D. Poor hygiene

Answer: (A)

A medication allergy can indeed result in a rash on the arm. Allergic reactions to medications can manifest as various types of rashes, including hives, redness, and itching. The immune system mistakenly identifies a drug as harmful, resulting in a skin response as part of the allergy. This is particularly important to consider, as reactions may occur shortly after starting a new medication or even after taking the same medication for a long time. The response is often localized to areas of skin, such as the arm, especially if the medication has been administered via injection or if it is absorbed through the skin in some manner. In contrast, while infections can cause rashes, they often involve other systemic symptoms such as fever or malaise and can vary greatly in presentation. Genetic disorders may lead to skin manifestations as well but are typically more chronic and would often present with additional features, not just a sudden rash. Poor hygiene can contribute to skin issues as well, but these would more often lead to irritations or infections rather than an allergic reaction-based rash.
