• Question 483:

  What component is indicated for patients who receive directed donations from immediate family members to prevent transfusion-associated graft versus host disease (TA-GVHD)?

  A. Irradiated Red Blood Cells
  B. Washed Red Blood Cells
  C. IgA-deficient products
  D. HLA matched products
  D. HLA matched products

• Question 484:

  Hemolytic transfusion reactions seldom occur because the incidence of unexpected antibodies in random patients is relatively low, e.g., 3-5% is sometimes cited.

  Being transfused with O Rh negative RBC is irrelvant if you have an unexpected antibody like anti-K or anti-c.

  Incompatible red cells may "bleed out" but only if bleeding is brisk. Even then, a hemolytic reaction may occur later once the patient's antibody rebounds and destroys remaining antigen-positive donor red cells.

  It's true that some patients have only cold-reactive antibodies that will not react at body temperature. But this does not explain why warm-reactive red cell antibodies cause few reactions

  Why do so few patients transfused with un-crossmatched red cells in an emergency experience a hemolytic transfusion reaction? Select the one best reason.

  A. The incidence of unexpected red cell antibodies is relatively low.
  B. They usually receive group O Rh negative red cells; a hemolytic transfusion reaction will never occur if O Rh-negative red cells are transfused.
  C. They hemorrhage so severely that incompatible donor red cells "bleed out" before a reaction occurs.
  D. Some patients have cold-reactive antibodies that will not react at body temperature.
  A. The incidence of unexpected red cell antibodies is relatively low.

• Question 485:

  Increased concentrations of alpha-fetoprotein (AFP) in adults are MOST characteristically associated with:

  A. hepatocellular carcinoma
  B. alcoholic cirrhosis
  C. chronic active hepatitis
  D. multiple myeloma
  A. hepatocellular carcinoma

• Question 486:

  There are many causes of CSF lymphocytosis. Lymphocytosis is seen in viral, fungal, and tuberculous infections, although a predominance of neutrophils may be present in the early stages of these infections. Lumbar puncture to obtain CSF samples is often contraindicated in those with a suspected brain abscess.

  CSF lymphocytosis is associated with all of the following except:

  A. Cerebral abscess
  B. Viral meningitis
  C. Chronic fungal meningitis
  D. Chronic tuberculous meningitis
  A. Cerebral abscess

• Question 487:

  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. fructosamine
  B. spun hematocrit
  C. blood glucose by home meters
  D. potassium
  D. potassium

• Question 488:

  The creatinine clearance for this patient is 100 mL/min.

  Creatinine clearance values are calculated using the following equation:

  Creatinine Clearance (mL / min) = (Urine Creatinine / Serum Creatinine) x Urine Volume (mL) / [ time (hr) x 60 ]

  For this patient Creatinine clearance (mL/min)= (120/1.5) x (1800 / [24 x 60])

  80 x 1800/1440, which is 80 x 1.25, or 100 mL/min

  A 45-year-old male of average height and weight had a serum creatinine of 1.5 mg/dL and urine creatinine was 120 mg/dL; the total volume of urine collected over a 24-hour period was 1,800 mL. Calculate the creatinine clearance for this patient in mL/min.

  A. 100
  B. 144
  C. 56
  D. 225
  E. 177
  A. 100

  A. At least enough to surround the primary receptacle
  B. Enough to completely absorb the specimen if the container leaked or broke
  C. Enough to fill the space between the primary receptacle and the secondary container
  D. There is no requirement for absorbent material
  A. At least enough to surround the primary receptacle

• Question 490:

  A. light blue, red, and lavender
  B. light blue, lavender, and red
  C. red, lavender, and light blue
  D. lavender, light blue, and red
  A. light blue, red, and lavender
