Which pair represents the temperatures associated with loss of consciousness?

• A. 83 F and 28 C
• B. 92 F and 33 C
• C. 75 F and 24 C
• D. 68 F and 20 C

Answer: (A)

Loss of consciousness from hypothermia occurs when core body temperature drops to about 28°C (roughly 82–83°F). The pair 83°F and 28°C sits right at that threshold, making it the best match. The other temperatures are either milder cold or not at the level where consciousness is typically lost: 33°C (about 91°F) is still cold but above the LOC range, while 24°C (75°F) and 20°C (68°F) are even less likely to produce unconsciousness.
