When assessing circulation in a trauma patient, which elements are included?

• A. Mental status, skin color and temperature, distal pulses, capillary refill.
• B. Lung sounds.
• C. Urine output.
• D. Blood glucose and temperature.

Answer: (A)

Circulation assessment in trauma focuses on whether blood is reaching vital tissues. Mental status is a quick read on brain perfusion—if the patient is awake or responsive, that suggests adequate circulation to the brain. Skin signs tell you about peripheral perfusion: cool, pale, or clammy skin indicates compromised circulation, while normal or warm skin can mean better perfusion. Checking distal pulses shows whether arterial blood is reaching the extremities, and capillary refill assesses how quickly blood returns to the capillaries after pressure is applied to a nail bed, with longer refill suggesting reduced perfusion. Lung sounds assess ventilation and oxygen exchange, not the immediate circulation status. Urine output reflects ongoing perfusion and kidney function over time, but it isn’t part of the quick circulation check. Blood glucose isn’t a direct measure of circulation, whereas temperature is already encompassed in skin signs when evaluating perfusion.
