Mom can answer yes or no questions, but lacks the wherewithal to regulate her own body temperature. When in bed, she cannot pull up the covers when she is cold nor pull them down when she is too hot.
Because humans are warm-blooded, this is kind of a big deal. If her internal temperature spirals out of control, she could lose the ability to process oxygen and die.
So I have gotten in the habit of frequently asking her if she is too hot or too cold, and adjusting things as needed.
