Which option represents an autonomic/physiologic sign?

• A. Breathing pattern
• B. Motor tone
• C. Crying
• D. Attention/interaction

Answer: (A)

Autonomic/physiologic signs are automatic bodily responses that reflect how the body's basic regulatory systems are functioning, such as breathing pattern, heart rate, skin color, and temperature. Breathing pattern is the best example here because it directly demonstrates autonomic control of respiration and can quickly signal changes in oxygenation or metabolic status, even in infants who can’t express symptoms verbally. Motor tone describes the baseline state of muscle tension and reflects neuromotor or CNS status, not automatic regulation. Crying is a behavioral/affective response driven by mood, needs, and comfort. Attention/interaction is a behavioral and social-cognitive function, showing how a child engages with others rather than how the body's automatic regulatory systems are functioning.
