ASCP ASCP Certifications ASCP-MLT Questions & Answers

• Question 511:

  Which of the following organizations now provides the certification exam for laboratory professionals?

  A. National Credentialing Agency (NCA)

  B. American Society for Clinical Laboratory Scientists (ASCLS)

  C. Board of Registry (BOR)

  D. National Accrediting Agency for Clinical Laboratory Sciences (NAACLS)

  Correct Answer: C

• Question 512:

  If your reactions are strong at immediate spin (3+) and then get weaker at AHG (w+), it could mean the presence of a strong cold antibody.

  Cold antibodies tend to be IgM and their optimum phase for reactivity is immediate spin. Incubation and washing of the sample may cause the agglutination that occurred at room temperature to break down. This would appear as a weaker

  reaction at AHG.

  If the reaction strengths varied in each panel cell then that could be an indication that there are multiple antibodies present.

  Your screen cells are 3+ at immediate spin and weak (W)+ at AHG. Your auto control is negative for both phases. Some of your antibody panel cells are 3+ at immediate spin and negative at AHG.

  What should you suspect?

  A. A warm autoantibody is present

  B. A cold antibody may be present

  C. Bad specimen draw

  Correct Answer: B

• Question 513:

  Set of comprehensive safety guidelines designed to protect patients and health care workers

  A. Standard Precautions

  B. Universal blood precautions

  C. Microscope

  D. Transmission precautions

  Correct Answer: A

• Question 514:

  The Westgard multi-rule 22S describes the scenario where two consecutive data points fall outside +2SD or -2SD. If this occurs, then the run must be rejected. This situation is most likely caused by a systematic error. Which of the following describes the Westgard multi-rule 22S?

  A. Two control data points are within ±2s

  B. One control data point falls outside +2s and a second point falls outside - 2s

  C. Two consecutive data points fall outside +2SD or -2SD

  D. Two consecutive data points fall inside +2s

  E. Two points are within 2SD

  Correct Answer: C

• Question 515:

  Epidemiology studies only infectious diseases that impact humans

  A. True

  B. False

  Correct Answer: A

• Question 516:

  The hepatitis B vaccine is a series of immunizations consisting of three injections of the hepatitis B antigen. The antigen causes the recipient of the injection to make antibodies against the antigen, hence why this is an example of active

  immunity.

  Immunology

  The hepatitis B virus vaccine was administered to MLS students during Orientation. Which type of immunity is expected to develop and provide long-term protection?

  A. active

  B. passive

  C. adoptive

  D. innate

  E. inactive

  Correct Answer: A

• Question 517:

  HbsAg is positive in acute and chronic Hepatitis B infections, since the antigen is found on the actual surface of the virus. HbeAg is present in the blood when the hepatitis B viruses are replicating, indicating an active infection. Anti-Hbc IgM is present due to the immune response to the presence of the hepatitis core antigen and indicates an acute infection. Anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection, according to the CDC. Given the following results, what is the immune status of the patient? HbsAg: positive HbeAg: positive Anti-HBc IgM: positive Anti-HBs: negative

  A. acute infection

  B. chronic infection

  C. immunization

  D. susceptible

  Correct Answer: A

• Question 518:

  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

  Correct Answer: D

• Question 519:

  The structures involved in the production of semen include the prostate, the seminal vesicles, and the bulbourethral gland, along with the testes and epididymis.

  Semen is produced as a combination of secretions from the different regions of the male reproductive tract. Each fraction differs in chemical composition and function.

  Spermatozoa are produced in the testes. They mature in the epididymis. The testes also produce testosterone and inhibin.

  Fluid from the seminal vesicles accounts for approximately 70% of semen volume. The seminal vesicles are the source of fructose in semen. Fructose is used by the spermatozoa as an energy source.

  The prostate gland supplies about 20% of the volume of semen. Its fluids include acid phosphatase and proteolytic enzymes that lead to coagulation and subsequent liquefaction of semen. The prostate also contains most of the IgA found in

  semen.

  The bulbourethral gland produces mucoproteins that make up about 5% of the volume of semen.

  The pituitary gland is not directly involved in the production of semen; instead hormones are released which stimulate the production of sperm. The urethra is not involved in the production of semen.

  Which of the following are directly involved in the production of semen?

  A. Prostate

  B. Pituitary gland

  C. Seminal vesicles

  D. Bulbourethral gland

  E. Urethra

  Correct Answer: ACD

• Question 520:

  To obtain a serum sample for a stat test on a patient receiving anticoagulant therapy, the recommended tube is: Question options:

  A. yellow/gray or orange

  B. red

  C. light green

  D. red/gray or gold

  Correct Answer: A
