ASCP ASCP-MLT Online Questions & Answers

• Question 161:

  If a drug is given at intervals that are the same as its half-life, it will take about 5 half-lives to reach steady state.

  If a drug is given at intervals that are the same as its half-life, approximately how long will it take the drug to reach steady state?

  A. It will be at steady state from the first dose.
  B. It will take about two half-lives to reach steady state.
  C. It will take about 5 half-lives to reach steady state.
  D. It will never reach a steady state.
  C. It will take about 5 half-lives to reach steady state.

• Question 162:

  Following an AMI, elevated CK-MB returns to normal ranges in 48-72 hours. If a patient has a second AMI in this time period, a second rise in concentrations of CK-MB would be seen. This is not true for the cardiac troponins since they remain elevated 7-14 days following an AMI.

  Which one of the following cardiac biomarkers could detect a reinfarction?

  A. cTnI
  B. cTnT
  C. TnC
  D. CK-MB
  D. CK-MB

• Question 163:

  Listeria are non-capsulated, non-acid-fast, ?hemolytic, gram-positive bacilli that have a characteristic tumbling motility. They are found primarily in the environment and in the human GI tract. Since L. monocytogenes multiplies intracellularly, control of listeriosis requires cell-mediated immunity; thus, immunocompromised patients (such as newborns) are at high risk.

  Which bacterial species is a common agent of neonatal bacteremia?

  A. Streptococcus pyogenes
  B. Listeria monocytogenes
  C. Staphylococcus aureus
  D. Enterococcus faecium
  B. Listeria monocytogenes

• Question 164:

  Mrs. Jones, a diabetic, is admitted to the hospital on November 25th. It appears that she has had an AMI but did not feel the severe chest pain because of diabetic neuropathy. She has not felt well since November 20th and her physician believes she possibly had an AMI on November 20th.

  Assuming that the infarct was uncomplicated, which of the following cardiac biomarkers would most likely still be elevated and would assist in an AMI diagnosis?

  A. Myoglobin
  B. Creatine kinase MB (CK-MB)
  C. Cardiac troponin I (cTnI) or cardiac troponin T (cTnT)
  C. Cardiac troponin I (cTnI) or cardiac troponin T (cTnT)

• Question 165:

  Synovial fluid is actually quite viscous and does not have the same consistency as plasma. The reason for its thicker consistency is to provide cushion and reduce friction between the articular cartilage of synovial joints during movement.

  Urinalysis and Other Body Fluids

  All of the statements below about synovial fluid are true EXCEPT:

  A. arthrocentesis is performed as a means to evaluate arthritis and other joint disorders
  B. synovial fluid is present only in movable joints
  C. joint fluid resembles plasma in viscosity
  D. joint fluid has approximately the same glucose as plasma
  C. joint fluid resembles plasma in viscosity

• Question 166:

  The beta hemoglobin chain loci are found on which chromosome?

  A. Chromosome 11
  B. Chromosome 16
  A. Chromosome 11

• Question 167:

  Serum calcitonin is normally produced by the C cells of the thyroid. It functions to reduce serum calcium by inhibiting release of calcium from bone. It is a peptide with a molecular weight of 3400, and has a half life of approximately 12 minutes. It is characteristically elevated in medullary carcinoma of the thyroid. Since medullary carcinoma often occurs as an autosomal disorder, family members of patients with this condition should be screened for serum calcitonin.

  Serum calcitonin is typically elevated in which of the following conditions:

  A. Medullary carcinoma of the thyroid
  B. Hyperthyroidism
  C. Glioblastoma
  D. Adrenal adenoma
  A. Medullary carcinoma of the thyroid

• Question 168:

  A regional laboratory that performs high volume, highly complex or infrequently ordered testing is a:

  A. reference laboratory
  B. physician's office.
  C. wellness clinic.
  D. long-term care facility.
  A. reference laboratory

• Question 169:

  Myoglobin release is strongly associated with muscle damage; therfore, it would most closely match a diagnosis of massive muscle trauma in this question.

  Myoglobinuria is MOST likely to be noted in urine specimens from patients with which of the following disorders?

  A. hemolytic anemia
  B. lower urinary tract infections
  C. massive muscle trauma
  D. paroxysmal nocturnal hemoglobinuria
  C. massive muscle trauma

• Question 170:

  DAT ( Direct Antiglobulin Test ).

  When AHG or Coombs serum is used to demonstrate that red cells are antibody coated in vivo, the procedure is termed:

  A. Indirect technique
  B. Direct technique
  C. Hemagglutination technique
  D. Hemolysis technique
  C. Hemagglutination technique
