You are examining a client with respiratory distress. Which physical assessment would best determine if the client has acute hypoxemia?

A. Clubbing is a sign of chronic hypoxia, not acute hypoxemia. B. Cyanosis, a bluish discoloration of the skin and mucous membranes, is an indicator of acute hypoxemia. C. Palpating for decreased tactile fremitus is related to fluid or air in the lungs, not specifically hypoxemia. D. Auscultation for adventitious breath sounds can reveal respiratory issues but does not directly confirm hypoxemia.
