Which is a listed medical impact of bed bug bites?

• A. Loss of sleep
• B. Pain, a welt, and itchiness
• C. Anxiety
• D. Allergic reactions

Answer: (B)

Bed bug bites typically cause a localized skin reaction: itchy welts that can be painful. This combination—pain, a welt, and itchiness—is the most common and direct medical impact described for the bite itself, which is why it’s the best choice.

While anxiety or trouble sleeping can occur in response to an infestation, and allergic reactions can happen in some individuals, these are not the typical immediate bite reaction. The standard, widely observed outcome of a bite is the itchy, raised skin lesion (welts) that may be painful.
