• Question 44:

  The most important purpose of a requisition form is: Question options:

  A. authorization to perform the procedure
  B. location of the patient
  C. providing a system to report results
  D. monitoring test result turnaround time
  A. authorization to perform the procedure

• Question 45:

  True Statements:

  Urine should be well mixed prior to dipping the reagent strip. Prolonged immersion may wash out test reagents.

  False Statements:

  Urine should be centrifuged prior to dipping the reagent strip. When visually reading the reagent strip, all results can be read immediately after dipping the strip in the urine specimen.

  Which of the following statements are TRUE regarding the reagent strip test procedure? (Choose ALL of the correct answers)

  A. Urine should be centrifuged prior to dipping the reagent strip.
  B. Urine should be well mixed prior to dipping the reagent strip.
  C. When visually reading the reagent strip, all results can be read immediately after dipping the strip in the urine specimen.
  D. Prolonged immersion may wash out test reagents.
  B. Urine should be well mixed prior to dipping the reagent strip.
  D. Prolonged immersion may wash out test reagents.

• Question 46:

  No HLA matching is performed for corneal tissue transplants as the cornea occupies a privileged site not usually seen by the immune system. This term has been coined "immune privileged".

  Corneal tissue may be transplanted successfully from one patient to another because:

  A. Anti-corneal antibodies are easily suppressed
  B. Corneal antigens do not activate T cells
  C. The cornea is non-antigenic
  D. The cornea occupies a privileged site not usually seen by the immune system
  E. The cornea has the same DNA in everyone.
  D. The cornea occupies a privileged site not usually seen by the immune system

• Question 47:

  A slow, progressive drift of values away from the mean is called a trend. Trends occur when a particular analyte value slowly and progressively changes in one direction from one run to the next. Monitoring data for trends is part of good laboratory practice and is one indicator of many that helps laboratorians determine whether the measurement system is fucntioning appropriately.

  A slow, progressive drift of values away from the mean is called a:

  A. Coefficient of Deviation
  B. Dispersion
  C. Trend
  D. Variance
  E. Sh
  C. Trend

• Question 48:

  2(2)2s = reject when 2 consecutive control measurements exceed the same mean plus 2s or the same mean minus 2s control limit.

  Violation of this Westgard rule is usually caused by a systematic error.

  Laboratory Operations

  Which of the following describes the Westgard multirule 2(2)S?

  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 +2s or fall outside -2s
  D. Two consecutive data points fall outside +2s
  E. Synonymous with R4s
  A. Two control data points are within + 2s

• Question 49:

  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
  B. Increased vasoconstriction

• Question 50:

  Gamma globulin (anti-D) is given to Rh-negative mothers to prevent any D antibody production, which could cause harmful effects in future pregnancies with an Rh-positive fetus. The administered anti-D will bind fetal Rh-positive cells that may come from the fetus in vivo; therefore the mother will not produce anti-D herself, preventing sensitization.

  A solution of gamma globulins containing anti-Rh (D) is given to an Rh (D) negative mother to:

  A. Prevent fetal cells from initially sensitizing the mother
  B. Neutralize any of the child's antibody that may have passed the placental barrier
  C. Neutralize any natural maternal antibodies present
  D. Prevent greater antibody response in a previously sensitized mother
  A. Prevent fetal cells from initially sensitizing the mother
