I agree! Also, At the end of the stem, the question is which of the following best explain the patients symptoms? Not physical exam findings. Since this patient is coming in with a chief complaint of SOB while playing sports exercise induced asthma is the best choice. Hopefully that helps.
I mean... couldn't increased BP during exercise worsen his MVP and give him SOB?
(by causing slight regurg)
"Lungs are clear to auscultation"
But wouldn't choosing exercise-induced asthma leave the murmur unaccounted for?
I incorrectly chose malingering and am wondering if the fact that he presented (although it doesn't state who brought him in/confirmed his symptoms while exercising) makes this less likely despite the fact that he clearly states "I don't want to play anymore" which could be interpreted as a secondary gain? Also, regarding the MVP, I'm wondering if the fact that these are usually benign should have factored into our decision to rule it out? Thoughts?
Just noticed that he has FHx, game changer.
clear lungs, they try to say no cardiogenic Pulm. edema, means is not due to MVP
shortness of breath while doing sports and no shortness at rest makes me to think more asthma induced by exercise)
Isn't exercise induced asthma usually found in people running outside, especially in cold weather? I feel like that is how it is always presented in NBME questions, so this threw me off. Not to mention the MVP.
it took me a little; the FHx really pushed me to exercise induced. I was also looking at malingering but there wasnt a real reason to push me to this (as a doctor it would be sad to be like hes faking it becasue he doesnt want to play sports with out being sure first; led me away because there wasnt enough pointing there). Also MVP could be slightly benign and is very common and usually no Sx and his lungs were clear as was rest of exam. All pushed to Asthma
I think MVP on its own shouldnt cause SoB with cough (in a question, I'm sure it could in the real world). In the world of NBME questions where you need to follow the physiology perfectly, you would need some degree of MR that lead to LV dysfunction/vol overload, and theres no pulmonary edema nor an S3 that point us towards that. Malingering would have to be faked for gain, and theres no external gain here or evidence that he's faking symptoms. You would also need to r/o physical illness before diagnosing malingering, which hasnt been done. Cold weather is certainly known for exacerbating EIA and are the exam buzzwords, but any exercise can absolutely be a trigger
he also has a family history of asthma. that's shit is genetic. +1 for asthma.
Cheif complaint is SOB during exercise with coughing. Mitral valve prolapse is not going to do that so I picked asthma as well.
He also has MVP, but asthma is more likely to cause this symptomatology and he has a family hx.
Thank you very much bro :-)
