When obtaining a drug history from Harold, he gives you a complete list of his prescription medications. He denies taking any other drugs, but you find that he occasionally takes aspirin for his arthritis flare ups. This is an example of:

A) His appropriately only telling you about his regularly prescribed medications
B) His hiding information regarding his inappropriate use of aspirin from you
C) A common misconception that intermittently taken over-the counter medications are not an important part of his drug history
D) A common misuse of over-the-counter aspirin
