sluggish pupil response to light.

Compartment syndrome occurs secondary to

soft tissue damage

In the acute phase of stroke, treatment is focused on

stabilization of respiratory and cardiovascular function.

Enteropathic arthritis is associated with

inflammatory bowel disease.

________ edema occurs when ischemic tissue swells because of cellular energy failure.

CYTOTOXIC

Intracranial pressure normally ranges from ______ mm Hg.

0 to 15

Which neurologic disorder is commonly referred to as Lou Gehrig disease?

Amyotrophic lateral sclerosis

Tophi are

deposits of urate crystals in tissues

Complete healing of a bone fracture occurs when

the callus has been completely replaced with mature bone.

The primary reason that prolonged seizure activity predisposes to ischemic brain damage is that

the lack of airway maintenance can lead to hypoxia.

The final stage of gout, characterized by crystalline deposits in cartilage, synovial membranes, and soft tissue, is called

tophaceous gout.

Slow pain sensation is transmitted primarily by

unmyelinated C fibers.

"Tell me again the name of that chemical that makes crystals when my gout flares up," asks the client. The nurse's best response is

uric acid

"Tell me again the name of that chemical that makes crystals when my gout flares up," asks the client. The nurse's best response is

uric acid.

Rickets is characterized by soft, weak bones resulting from a deficiency of

vitamin D

8

An example of inappropriate treatment for head trauma would be
