Fever

The presence of exogenous pyrogens causes the production of endogenous pyrogens such as cytokiens by immune cells. where do the exogenous pyrogens come form.

• injured tissue

• invading pathogens

• both of the above

The part of the brain which regulates body temperature is called

• The hypothalamus

• The hippocampus

• The hypodermia

In fever the body internal/core tempo is increased to

• Increase the rate at which immune cells can function

• Reduce the growth of microbes

• both of the above

Increased body temp is achieved through the production of chemicals which cause

• vasodilation to increase blood flow to the area

• Vasoconstriction

• Vascular perforation

Vasoconstriction

• Reduces the size of the blood vessel lumen and restricts the flow of blood to the extremities of the body

• Increases the size of the vascular lumen and increases the flow of blood to the extremities

At the beginning of a fever the patient will feel

• cold

• hot

• no change

The early stage during which the core temp is rising is known as the

• Onset

• Offset

• Upset

To assist in the process to increase the body temperature the patient also

• shivers

• sneezes

• sweats

During the stationary phase of fever the patient has flushed skin and feels hot. This is caused by

• Vasoconstriction

• Vasodilation

• Vasofiltration

The patient will then engage in other activities to encourage temp homeostasis

• sweating

• smiling

• singing
