ASCP ASCP-MLT Online Questions & Answers

• Question 261:

  Failure to tightly seal specimens for sweat electrolytes during collection and transport will cause:

  A. decreased values due to exposure to air
  B. decreased values due to exposure to light
  C. increased values due to evaporation
  D. increased values due to cellular contamination
  C. increased values due to evaporation

• Question 262:

  hs-CRP is a more sensitive version of the C-reactive protein (CRP) test, a test that has been used for many years to assess inflammation in settings such as lupus, transplantation, infection, etc. Which of the following cardiovascular risk markers is a more sensitive version of a test that is used to assess inflammation?

  A. Oxidized-LDL
  B. hs-CRP
  C. ApoB/ApoA1
  D. LpPLA2
  B. hs-CRP

• Question 263:

  The blood glucose value is critical; negative ketones is consistent with type 2 diabetes. An elderly type 2 diabetic patient is at risk for hyperosmolar non-ketotic coma and osmolality should be measured.

  A measurement of urine glucose would not be useful at this point.

  A 70-year-old type 2 diabetic patient is comatose and in the emergency department. Stat blood glucose and serum ketones are ordered.

  Blood Glucose: 650 mg/dL

  Serum Ketones: Negative

  What is the best conclusion?

  A. Glucose result is acceptable for type 2 diabetic patient
  B. Because of the glucose and ketone result, the patient now has type 1 diabetes
  C. The glucose result is critical and the patient should be evaluated for hyperosmolality
  D. Urine glucose should be measured
  C. The glucose result is critical and the patient should be evaluated for hyperosmolality

• Question 265:

  Serum amylase and lipase levels may be slightly elevated in chronic pancreatitis, but not diagnostic enough to predict chronic pancreatitis; wheras high levels are found only during acute pancreatitis episodes. In the later stages of chronic pancreatitis, normal to decreased levels of amylase and lipase are caused by the gradual inability of the pancreas to secrete the enzyme

  All of the statements below regarding amylase and lipase in pancreatitis are TRUE EXCEPT:

  A. Amylase and lipase are as predictive in chronic as in acute pancreatitis.
  B. Diagnosis sensitivity is increased by assaying both amylase and lipase.
  C. Urinary amylase: creatinine ratio is the most sensitive test for acute pancreatitis.
  D. Serum lipase peaks at 24 hours after an episode of acute pancreatitis and remains high for 7-8 days.s.
  A. Amylase and lipase are as predictive in chronic as in acute pancreatitis.

• Question 266:

  What two glycoproteins are expressed on the surface of influenza A viruses and are used for subtyping of the viruses?

  A. Hemagglutinin
  B. Glycoprotein120 (gp120)
  C. Glycoprotein41 (gp41)
  D. Neuraminidase
  A. Hemagglutinin

• Question 267:

  Waived tests are those considered to have an insignificant risk of erroneous results. Which of the following is NOT an example of a waived test?

  A. rapid strep tests from throat swabs
  B. sodium
  C. HIV antibodies
  D. prothrombin time
  B. sodium

• Question 268:

• Question 270:

  The term that is used to describe the color in these tubes of CSF is "xanthochromia." Xanthochromia is an abnormal color, usually yellow, orange, or pink, in the supernatant of the CSF sample. It may indicate that a subarachnoid hemorrhage (SAH) has occurred.

  

  Jaundice and icterus both describe a yellowing of the skin, mucous membranes, and eyes. Blood plasma/serum that is deep yellow is also described as icteric. What term is used to describe the color in these tubes of cerebrospinal fluid (CSF)?

  A. Jaundice
  B. Xanthochromia
  C. Icterus
  B. Xanthochromia
