A patient presented to the emergency department of the hospital with a swollen, reddened, painful leg wound and has been diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) cellulitis.
 
  The patient's physician has ordered a complete blood count and white cell differential. Which of the following blood components would the physician most likely anticipate to be elevated?
  A)
  Basophils
  B)
  Eosinophils
  C)
  Platelets
  D)
  Neutrophils

Question 2

The nurse knows which of the following statements listed below is accurate regarding the functions and nature of cytokines relative to a variety of pathologies?
 
  A)
  A particular cytokine can have varied effects on different systems, a fact that limits their therapeutic use.
  B)
  Cytokine production is constant over time, but effects are noted when serum levels cross a particular threshold.
  C)
  Most cytokines are produced by granular leukocytes, and different cells are capable of producing the same cytokine.
  D)
  Cytokine actions are self-limiting, in that activation of one precludes activation of other cytokines with similar actions.

Answer to Question 1

Ans:
D

Feedback:

Increased neutrophils are associated with inflammation in general and bacterial infections in particular. Platelets play a role in inflammation, but their levels would not rise to the same extent as would neutrophils'. Eosinophils are not strongly associated with bacterial infection, and basophils would not increase to the same degree as neutrophils.

Answer to Question 2

Ans:
A

Feedback:

Because cytokines can mediate diverse effects due to their pleiotropic properties, they can have significant side effects. Cytokine production is brief, not constant, and production does not normally take place in granulocytes. Activation of a cytokine does not necessarily limit other similar cytokines, and additive effects are not uncommon.
