A patient comes to the emergency room for evaluation of shortness of breath. To which anatomic region would you assign the symptom?
A) Reproductive
B) Urinary
C) Cardiac
D) Hematologic
C) Cardiac
Cardiac disorders such as congestive heart failure are the most likely on this list to result in shortness of breath. There are cases within the other categories which may also result in shortness of breath, such as anemia in the hematologic category, pregnancy in the reproductive category, or sepsis with UTI in the urinary category. This demonstrates the “tension” in clinical reasoning between making sure all possibilities are covered, while still being able to pick the most likely cause.
