  A. 0 - 4 degrees Celsius

• Question 447:

  Using the formula on the right,

  

  Cells/μL = 370 x 100 / 18 x 0.1 Cells/μL = 37000 / 1.8 Cells/μL = 20556 or 2.06 x 104 A sample of cerebrospinal fluid is diluted 1:100; the standard 9 squares of a hemocytometer are counted on each side for a total of 18 large squares. Side 1-- 186 nucleated cells counted Side 2-- 184 nucleated cells counted total nucleated cells = 370 Using the standard hemocytometer formula shown on the right, what is the nucleated cell count per microliter (μL)?

  A. 1.03 x 10^4

• Question 448:

  Spirochetes such as Borrelia and Treponemes are best visualized using darkfield microscopy. Borrelia, which causes Relapsing fever, can be visualized under darkfield microscopy of wet preps of peripheral blood. Treponema can be visualized by darkfield microscopy of early primary lesions, and aspirates of affected lymph nodes.

  Which of the following organisms is best visualized by use of a darkfield microscope:

  A. Campybacter

  B. Entamoeba

  C. Borrelia

  D. Streptococcu

  Correct Answer: C

• Question 449:

  In DIC, or disseminated intravascular coagulation, the prothrombin time is increased due to the consumption of the coagulation factors due to the tiny clots forming throughout the vasculature. This is also the reason that the fibrinogen levels and platelet levels are decreased. Finally FDP, or fibrin degredation products, are increased due to the formation and subsequent dissolving of many tiny clots in the vasculature. The FDPs are the pieces of fibrin that are left after the fibrinolytic processes take place.

  Which of the following laboratory results would be seen in a patient with acute Disseminated Intravascular Coagulation (DIC)?

  A. prolonged PT, elevated platelet count, decreased FDP

  B. normal PT, decreased fibrinogen, decreased platelet count, decreased FDP

  C. prolonged PT, decreased fibrinogen, decreased platelet count, increased FDP

  D. normal PT, decreased platelet count, decreased FDP

  Correct Answer: C

• Question 450:

  Enterococcus spp. are bile esculin positive and grow in 6.5% NaCl. If they grow on the 6

  Correct Answer: D
