A patient is experiencing a fever. What structure should the nurse expect to provide an effective cooling mechanism for the body?
a. Capillaries
b. Eccrine glands
c. Adipose tissue
d. Ceruminous glands
ANS: B
Eccrine glands are found throughout the dermis but are most numerous on the face, palms, and soles. They are activated by high temperatures or by exercise and secrete sweat onto the skin surface. The sweat is evaporated by excess body heat, which is a very effective cooling mechanism, although it does have the potential to lead to dehydration if water is not replaced by drinking. C. Subcutaneous adipose tissue cushions some bones and provides some insulation from cold, but its most important function is energy storage. D. Modified sweat glands called ceruminous glands are found in the dermis of the ear canals. Their secretion is called cerumen or earwax. A. Capillaries may dilate to release heat however this is not the most effective cooling mechanism in the body.
