• Question 12:

  In this case, the pH may become more alkaline, perhaps above 8.0, if the bacteria in the sample are proliferating during the extended room-temperature wait time.

  A urine specimen was collected at 6:00 a.m. and remained at room temperature until it was received in the laboratory at 3:30 p.m. How may the pH of the specimen be affected by the extended time at room temperature if bacteria are present in the specimen?

  A. The pH may become more acidic.
  B. The pH may become more alkaline.
  C. The pH would probably not be affected.
  C. The pH would probably not be affected.

• Question 13:

  Small, dense LDL is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis. Small, dense LDL is associated with more than a three-fold increase in the risk of coronary heart disease.

  Large, buoyant LDL is less atherogenic than small, dense LDL. The LDL phenotype A is normal. It is the so called 'B' pattern that is associated with increased risk.

  Which of the following is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis?

  A. Large buoyant LDL
  B. Small dense LDL
  C. LDL phenotype 'A'
  B. Small dense LDL

• Question 14:

  Electrophoresis uses an electric field to separate molecules based on differences in net electrical charge. The rate of electrophoretic migration is also dependent on the ionic radius of the molecule, the viscosity of the solution through which it is migrating, the electrical field strength, temperature, and the type of supporting medium used.

  Electrophoretic separation fundamentally relies on:

  A. Size differences of molecules
  B. Net charge differences of molecules
  C. Concentration differences of molecules
  D. Shape variations of molecules
  A. Size differences of molecules

• Question 15:

  Match each of the following:

  1.

  Ratio of cellular area to total area in the bone marrow section.

  2.

  Number of myeloid cells compared to nucleated erythroid cells.

  3.

  Use low power to estimate their quantity and appearance.

  4.

  Use Perls' Prussian blue stain.

  A. Myeloid-erythroid ratio
  B. Stored iron
  C. Overall cellularity
  D. Megakaryocytes
  A. Myeloid-erythroid ratio
  B. Stored iron
  C. Overall cellularity
  D. Megakaryocytes

• Question 16:

  Personal protective equipment (PPE) should be put on in the following order:

  A. gloves, gown, and mask
  B. gloves, mask, and gown
  C. gown, mask, and gloves
  D. mask, gloves, and gown
  C. gown, mask, and gloves

• Question 17:

  Alpha thalassemia is a hemolytic anemia. In most hemolytic anemias the LD and bilirubin are increased while the haptoglobin is decreased. However, because haptoglobin binds to the alpha chain portion of hemoglobin, it usually remains at normal levels due to the absence of alpha chains in the destroyed cells.

  Which set of chemistry results would most likely occur during hemolytic crisis in alpha thalassemia intermedia?

  A. Decreased lactate dehydrogenase (LD)and bilirubin, and increased haptoglobin
  B. Increased LD and bilirubin,and decreased haptoglobin
  C. Increased LD and bilirubin, and normal haptoglobin
  D. Normal LD and bilirubin, and decreased haptoglobin
  C. Increased LD and bilirubin, and normal haptoglobin

• Question 18:

  Secondary granules, also known as specific granules first appear in the myelocyte stage next to the nucleus. In neutrophils this is termed the "dawn of neutrophilia".

  What is one of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm?

  A. Appear first at the myelocyte stage
  B. Dissolve in mature granulocytes
  C. Are formed on the mitochondria
  D. Are derived from azurophil (primary) granules
  A. Appear first at the myelocyte stage

• Question 19:

  After collection all blood should be stored at 1 - 6oC, unless it is going to be used as a source of platelets.

  A refrigerator used to store whole blood must be able to maintain a temperature in the ranges of:

  A. 0 - 4 degrees Celsius
  B. 2 - 4 degrees Celsius
  C. 2 - 8 degrees Celsius
  D. 1 - 6 degrees Celsius
  D. 1 - 6 degrees Celsius

• Question 20:

  The microscopic features shown here represent Scopulariopsis species. In most instances, particularly if a patient does not have underlying immunologic or hematologic disease, Scopulariopsis species should be considered a contaminant

  when recovered from a sputum specimen. However, if there is clinical or X-ray evidence of mycotic pulmonary infection, additional daily induced sputum specimens should be obtained.

  If Scopulariopsis species or any other hyaline mold is recovered from two or more successive specimens, its potential as a pathogenic agent should be considered. Scopulariopsis species have been reported as the agents of pulmonary

  fungus ball infections in patients with preexistent cavities and as a cause of pneumonia in patients with leukemia.

  Invasive pulmonary disease by this agent has not been reported.

  The fungus illustrated in this photomicrograph was recovered from an induced sputum specimen from a 74 year old man with chronic obstructive pulmonary disease. This isolate is most likely:

  

  A. The cause of chronic bronchitis
  B. The cause of invasive pulmonary disease
  C. The cause of allergic bronchopulmonary disease
  D. A contaminant
  D. A contaminant
