Clinical Medical Assistant Exam Practice Question

Correct Answer: B

Rationale: A patient's social history encompasses lifestyle factors and behaviors that can impact health. Option B, the patient's history of smoking, directly relates to lifestyle choices and is a key component of social history.

Option A, previous surgeries, pertains to medical history rather than social context. Option C, history of hypertension, is a medical condition that falls under medical history as well. Option D, family history of heart disease, focuses on genetic predisposition and family medical background, not individual social factors. Thus, only option B aligns with the definition of social history.
