Question

Which of the following would not be a likely cause of exanthematous (morbiliform) drug eruption?

a) penicillin
b) allopurinol
c) steroids
d) sulfas
e) NSAIDs
f) ACE inhibitors

Answer 1

Steroids are not a likely cause of exanthematous (morbiliform) drug eruptions, as they are generally used to treat such inflammatory reactions, unlike medications like penicillin and sulfa drugs that commonly induce them.

Step-by-step explanation:

The question pertains to exanthematous (morbiliform) drug eruptions, which are skin reactions that typically occur following drug exposure. Exanthematous drug eruptions are most commonly associated with a reaction to certain medications. Among the drugs listed - penicillin, allopurinol, steroids, sulfa drugs, NSAIDs, and ACE inhibitors - steroids would not be a likely cause of exanthematous drug eruptions. Steroids are often used as treatment to reduce inflammation and suppress the immune system's reaction, which means they're less likely to induce this type of hypersensitivity skin reaction compared to the other medications listed.
