I frequently ask question such as are you taking any medications. Patients quite often start the answer with "no" then a few seconds later they reply-just tylenol or "no" just "Metformen"
Or when you are asking questions to parent about young Pt. "does he have stomach pain" answer No-after which mom asks the Patient "does your stomach hurt"
Do you have asthma, bronchitis, emphysema? No but I have it in my family. I asked you about your symptoms not your family hx!
