Which instrument is required for a general physical exam?

In a general physical exam, the otoscope is the essential instrument used for examining the ears, specifically the ear canal and eardrum. It allows healthcare providers to visualize any abnormalities or signs of infection in the ear structure. This examination is a critical component of a comprehensive physical assessment, as ear health can be indicative of other systemic issues.

The sphygmomanometer, while important for measuring blood pressure, is not used in all physical exams since blood pressure can be considered a separate assessment component. The reflex hammer is utilized to test neurological reflexes, which is part of a focused neurologic exam rather than a general physical exam. An electrocardiogram machine, used to assess heart electrical activity, is not a tool typically employed in routine physical examinations, as it is more specialized and utilized for specific cardiac evaluations. Thus, the otoscope stands out as the primary tool for a general physical examination, specifically addressing the ear health component.
