The mental status exam provides a structured assessment of which domains?

• A. Appearance and behavior, speech and language, mood, thoughts and perceptions, and cognitive function
• B. Blood pressure, heart rate, temperature, and oxygen saturation
• C. Motor strength, reflexes, and gait
• D. Sleep patterns and circadian rhythms

Answer: (A)

The mental status exam is a structured snapshot of a patient’s current mental functioning across several interconnected areas. It starts with appearance and behavior, which reflect grooming, hygiene, and any unusual psychomotor activity or agitation. Speech and language look at how the person speaks—rate, volume, fluency, articulation, and coherence. Mood and affect capture the patient’s reported emotional state and the clinician’s observed expression. Thoughts and perceptions examine how ideas are formed and organized, as well as any perceptual disturbances like hallucinations or delusions. Cognitive function assesses orientation, attention and concentration, memory, and higher-level abilities such as problem-solving and abstraction. These domains together define the mental status exam, whereas vital signs, a pure motor/neurological exam, or sleep history fall outside its scope.
