A survivor has been pulled from the water off the coast of Greenland. The patient is in a state of confusion and has ceased shivering. Which of the following best describes the patient's condition?

Correct Answer: Option D — the patient is suffering from moderate hypothermia

Ceasing to shiver alongside altered mental status or confusion indicates a core body temperature dropping below 90°F (32°C), classifying the condition as moderate to severe hypothermia. Shivering stops when the body's glycogen stores are depleted and thermal regulation fails.
