Which option lists a valid sign of hypoxemia during flight in an unacclimatized patient?

Explanation:
Reduced ambient oxygen at altitude challenges oxygen delivery, and unacclimatized travelers respond quickly with faster breathing and a faster heart rate to improve oxygen uptake and delivery. The combination of tachycardia and tachypnea reflects this immediate compensatory response, making it the best sign among the options. Nasal congestion isn’t a reliable indicator of hypoxemia, bradycardia isn’t typical in acute hypoxemia, and confusion alone doesn’t reliably signal early hypoxemia.
