ASCP ASCP-MLT Online Questions & Answers

• Question 211:

  The role of provider-performed microscopy (PPM) is the

  A. Process of performing laboratory testing at the bedside of the patient and a means of decentralizing some of the laboratory testing.
  B. Specific microscopic tests (wet mounts) performed by a physician for his or her own patients.
  C. Means by which quality control between laboratories is maintained.
  D. both moderately and highly complex
  B. Specific microscopic tests (wet mounts) performed by a physician for his or her own patients.

• Question 212:

  Hemoglobin electrophoresis uses an electric field to separate hemoglobin 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 of hemoglobin fundamentally relies on:

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

• Question 213:

  Anything that can cause significant turbidity in a blood sample, such as high leukocyte count or lipemia can potentially interfere with the accuracy of a spectrophotometric hemoglobin assay.

  Hematology

  Which of the following may interfere with the accurate measurement of hemoglobin:

  A. Leukocytosis
  B. EDTA
  C. Heparin
  D. Leukocytosis and lipemia
  D. Leukocytosis and lipemia

• Question 214:

  Where can one find guidance on the minimum performance standards for clinical laboratories?

  A. Food and Drug Administration (FDA)
  B. Centers for Disease Control and Prevention (CDC)
  C. Clinical Laboratory Improvement Amendments of 1988 (CLIA '88)
  D. National Institutes of Health
  C. Clinical Laboratory Improvement Amendments of 1988 (CLIA '88)

• Question 215:

  The activities conducted in a laboratory with a certificate of waiver include:

  A. tests that are simple to perform and have an insignificant risk for error
  B. moderate- or high-complexity lab testing until the lab is determined by survey to be in compliance
  C. high complexity tests only
  D. physicians to perform microscopy only
  A. tests that are simple to perform and have an insignificant risk for error

• Question 216:

  In an evacuated tube, blood flow into the tube depends on: Question options:

  A. air pressure
  B. gravity
  C. blood pressure
  D. the vacuum in the tube
  D. the vacuum in the tube

• Question 217:

  Abrupt change in temperature is one of the risk factors in which a sickling event may occur.

  Dehydration, hypoxia, and physical exertion, rather than excessive intake of fluids, inhaling oxygen, and sedentary lifestyle, are all additional risk factors in which sickling events may occur.

  Which of these could cause a sickling event?

  A. Excessive intake of water
  B. Fluctuations in temperature
  C. Oxygen inhalation
  D. Sedentary life-style
  B. Fluctuations in temperature

• Question 218:

  Howell-Jolly bodies are composed of DNA, usually left from the nucleus, that appears as a round, dark-staining inclusion in the cytoplasm of red blood cells. Howell-Jolly bodies can be found in various conditions including splenectomy and anemia.

  Remnants of erythrocyte nuclei, nuclear fragments, or aggregates of chromosomes are called:

  A. Heinz bodies
  B. Howell-Jolly bodies
  C. Basophilic stippling
  D. Pappenheimer bodies
  B. Howell-Jolly bodies

• Question 219:

  The term universal precautions refers to:

  A. treating only CERTAIN specimens as infectious.
  B. mixing organic chemicals under a hood.
  C. wellness clinic available to everyone.
  D. universal blood donors.
  A. treating only CERTAIN specimens as infectious.

• Question 220:

  The National Heart, Lung, and Blood Institute initiated the National Cholesterol Education Program (NCEP) in 1985. The goal was to reduce the number of Americans with elevated cholesterol and thus reduce illnesses and deaths in the United States due to coronary heart disease. Three adult treatment panels have been published since then with clinical practice guidelines for managing cholesterol levels in adults.

  The most recent panel, Adult Treatment Panel III (ATP III), was published in 2001 and updated in 2004. The NCEP: ATP III also includes criteria for the diagnosis of metabolic syndrome.

  Select the set of laboratory assays that are utilized in the NCEP: ATP III criteria for metabolic syndrome diagnosis.

  A. LDL-C, triglycerides, HDL-C, and fasting blood glucose
  B. Fasting blood glucose, triglycerides, insulin, and VLDL
  C. Fasting blood glucose, triglycerides, HDL-C
  D. Fasting blood glucose, triglycerides, HDL-C, and VLDL
  C. Fasting blood glucose, triglycerides, HDL-C
