Harry is hospitalized with bacterial pneumonia. When you visit him, his teeth are chattering, his skin is cool and clammy to the touch, and he complains of feeling cold, even though the room is quite warm. Explain his symptoms
What will be an ideal response
Harry's symptoms indicate a fever caused by his bacterial pneumonia. The white cells battling the pneumonia release pyrogens that act directly on the hypothalamus, causing its neurons to release prostaglandins. The prostaglandins reset the hypothalamic thermostat to a higher temperature, causing the body to initiate heat-promoting mechanisms including shivering and vasoconstriction that causes a decline of heat loss from the body surface, cooling of the skin, and shivering.
