• Question 121:

  The difference between plasma and serum is that:

  A. serum is the cells of unclotted blood.

  B. serum is obtained from a nonclotted specimen

  C. plasma is from an unclotted specimen.

  D. plasma is obtained from a clotted specimen.

  Correct Answer: C

• Question 122:

  Yellow stopper tubes are used for all of the following except: Question options:

  A. human leukocyte antigen (HLA) typing

  B. paternity testing

  C. blood cultures

  D. lead testing

  Correct Answer: D

• Question 123:

  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.

  Correct Answer: A

• Question 124:

  Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenals. A major action of angiotensin II is:

  A. Increased pituitary secretion of petressin

  B. Increased vasoconstriction

  C. Increased parathormone secretion by the parathyroid

  D. Decreased adrenal secretion of aldosterone

  Correct Answer: B

• Question 125:

  All of the following activities are associated with platelets EXCEPT:

  A. Aggregation

  B. Adhesion

  C. Lysis

  D. Release of granules

  Correct Answer: C

  A. fructosamine

  B. spun hematocrit

  C. blood glucose by home meters

  D. potassium

  Correct Answer: D

• Question 128:

  The newest direction for laboratory testing procedures is

  A. Larger automated instruments

  B. Networked systems for point-of-care testing

  C. Molecular diagnostic techniques in various laboratory departments

  D. Robotic specimen handling

  Correct Answer: C

• Question 129:

  A. leakage of coagulation factors into the serum or plasma by cellular metabolism; increased potassium values caused by exposure to room temperature; increased glucose values caused by cellular metabolism

  B. glycolysis caused by leakage from cells; increased levels of coagulation factors caused by prolonged exposure to room temperatures; decreased potassium levels caused by cellular metabolism

  C. glycolysis caused by exposure to room temperatures; hemolysis and leakage of coagulation factors from the cells; decreased potassium levels in the serum and plasma by cellular utilization

  D. glycolysis caused by cells' use of glucose; hemolysis and leakage of potassium from the cells into the plasma or serum; the destruction of coagulation factors from exposure to room temperatures

  Correct Answer: D
