In a physical exam, which term indicates a patient is alert?

The term that indicates a patient is alert is typically described as "normal." In a physical examination context, when a patient's level of alertness is normal, it means they are fully aware and responsive to their surroundings. This includes being oriented to person, place, and time, and able to engage in conversation appropriately.

In contrast, the other options describe varying degrees of altered consciousness or responsiveness. For instance, somnolent indicates a state of drowsiness or a reduced level of alertness where the patient is not fully awake; obtunded suggests that the patient has a significantly reduced level of awareness and requires strong stimuli to respond. "Well developed" pertains to the physical growth and development of the patient, which does not relate to their alertness or level of consciousness. Thus, the term "normal" clearly and accurately represents the state of alertness in a patient during a physical examination.
