ASCP ASCP-MLT Online Questions & Answers

• Question 121:

  Though automated extraction machines have many benefits over manual methods the costs are high and generally require a high throughput of samples in order to justify the costs.

  Automated extraction has many benefits over the traditional manual methods. The most important benefit is that the nucleic acid isolated is constantly consistent. There is a reduced amount of manipulation with dramatically decreases the

  chance of cross contamination. Also, automated extraction machines are considered moderate complexity and can be performed by a wider variety of laboratory professionals.

  All of the following are considered benefits of automated isolation and extraction equipment EXCEPT:

  A. Automated isolation equipment is cheaper and more practical
  B. Automated isolation equipment requires less manipulation
  C. Automated isolation equipment is considered moderate complexity
  D. Automated isolation equipment provides consistent results
  A. Automated isolation equipment is cheaper and more practical

• Question 122:

  The anticoagulant present in a light-blue stopper tube is:

  A. Ethylenediaminetetraacetic acid (EDTA)
  B. sodium citrate
  C. heparin
  D. potassium oxalate
  B. sodium citrate

• Question 123:

  The FTA-ABS is used to confirm that a positive non-treponemal test like RPR is not the result of a biological false positive, which occur in about 1 to 10 percent of the population.

  A positive RPR test and a negative FTA-ABS test is most likely the result of:

  A. Primary syphilis
  B. Secondary syphilis
  C. Latent syphilis
  D. False positive reaction
  D. False positive reaction

• Question 124:

  Immunoassay is the most common technique that is used by clinical laboratories for therapeutic drug monitoring.

  Most of the drugs commonly assessed with TDM can be measured on analytical platforms which utilize antibodies (in some form) for detection. Antibodies can be developed that recognize drugs. Although most drugs are much too small to

  evoke an immune response, scientists can conjugate drugs to immunogenic proteins to produce antibodies that recognize drug-specific epitopes.

  Which of the following is the most common technique that is used by clinical laboratories for therapeutic drug monitoring?

  A. Immunoassay
  B. Electrophoresis
  C. Atomic absorption
  D. Ion selective electrode voltimetry
  A. Immunoassay

• Question 125:

  Which of the following is NOT part of the magnification system of the microscope?

  A. arm
  B. 10 X objective lens
  C. ocular lenses-arm
  D. 4 X objective lens
  A. arm

• Question 126:

  On the red cell membrane, there is a bicarbonate / chloride exchanger. This exchanger allows for bicarbonate to leave the red cells while chloride is allowed inside. In blood, bicarbonate leaves the red blood cell and enters the plasma through an exchange mechanism with:

  A. sodium
  B. potassium
  C. chloride
  D. phosphorus
  C. chloride

• Question 127:

  Hemoglobin F has a high affinity for oxygen. When Hb F is elevated, cells containing Hb S are more oxygenated and do not sickle as readily as they would if Hb F were not present or present in small quantities. Which hemoglobin, when elevated, acts as a protection against sickling in patients with HbS?

  A. Hemoglobin A2
  B. Hemoglobin C
  C. Hemoglobin F
  D. Hemoglobin G
  B. Hemoglobin C

• Question 128:

  The deposition of plaques containing cholesterol and lipids on the innermost layer of the walls of large and medium-sized arteries is the defintion of atherosclerosis.

  Arteriosclerosis is a more general term that describes a thickening and loss of elasticity of the walls of the arteries (hardening of the arteries). Atherosclerosis is a type of arteriosclerosis but is not synonymous with it.

  Atherosclerosis is not the most common outcome for risk marker studies because it can be hard to measure. Infarcts, cardiac procedures, death, and 'events' are more common. Most humans have visible or measureable atherosclerosis by

  early middle age.

  Chemistry

  Which of the following is true concerning atherosclerosis?

  A. Atherosclerosis is the same as arteriosclerosis.
  B. Atherosclerosis is the deposition of plaques containing cholesterol and lipids on the innermost layer of the walls of large and medium-sized arteries.
  C. Atherosclerosis is the main outcome that is assessed in risk marker studies.
  D. Most humans do not have significant atherosclerosis.
  B. Atherosclerosis is the deposition of plaques containing cholesterol and lipids on the innermost layer of the walls of large and medium-sized arteries.

• Question 129:

  Hypochromia can best be described as:

  A. Immature red blood cells
  B. Abnormal erythropoiesis
  C. Increase in nucleated RBCs
  D. Decrease in Hgb concentration in RBCs
  A. Immature red blood cells

• Question 130:

  Unexplained bleeding is associated with immediate hemolytic transfusion reactions, but is not usually associated with delayed hemolytic transfusion reactions. The bleeding results from disseminated intravascular coagulation (DIC) due to ABO antibodies causing intraventricular hemorrhage (IVH).

  Which of the following signs and symptoms may be associated with immediate transfusion reaction, but is NOT usually associated with delayed hemolytic transfusion reaction?

  A. Fever and chills
  B. Unexplained bleeding from surgical site
  C. Unexplained drop in hemoglobin
  D. Transient jaundice
  B. Unexplained bleeding from surgical site
