Exam 2 Study Guide Flashcards

1
Q

What are the general Principles of Virology?

A

a. A virus cannot replicate on its own. It must attach to and enter a host cell.
b. A virus then uses the host cell’s energy to synthesize protein, DNA and RNA.
c. Viruses are difficult to kill because they live inside cells. (Any drug that kills a virus also kills healthy cells)

Q

What is the Pathophysiology of MS?

A

Triggers inflammation and loss of oligodendrocytes (myelin producing cells)

Loss of myelin disrupts nerve conduction and death of neurons and brain

A
  • Fatigue, weakness
  • Fractures (d/t decrease in Vitamin D not bein able to absorb calcium)
  • HTN, edema
  • Decrease EPO -> anemia
  • Weak immunity
  • Ammonia, urea and nitrogenous substances have affinity to CNS
  • Irritation -> neuropathy -> if severe -> confusion and decreased LOC
  • N/V, Not eating well
  • Crystal formation on skin
133
Q

What is the pathophysiology of complications of renal failure?

A

..

134
Q
