  B. Point-of-care testing (POCT)
  C. High complex testing
  D. Molecular testing
  B. Point-of-care testing (POCT)

• Question 114:

  A laboratory scientist is working the night shift at a local hospital when the power goes out. What is the course of action to continue to provide laboratory results?

  A. Wait until the power comes back
  B. Hold all laboratory testing until the power comes back
  C. Initiate the downtime protocol for an outage
  D. Wait until the physician calls asking for results
  C. Initiate the downtime protocol for an outage

• Question 115:

  AABB Standards do not require a DAT, autologous control, or a minor crossmatch for pretransfusion testing. Essential components of compatibility testing include all of the following except :

  A. Antibody screen on recipients serum
  B. Major crossmatch or computer crossmatch
  C. ABO and Rh typing of recipient
  D. Direct Antiglobulin Test (DAT)
  D. Direct Antiglobulin Test (DAT)

• Question 116:

  If Kappa or Lambda is predominant and CD5 is co-expressed with CD19 (CD19/CD5 dual positive lymphocyte population), and CD23 is expressed, chronic lymphocytic leukemia is a probable diagnosis. CD19 is normally found on normal B

  cell populations and CD5 is normally found on mature T cell populations. However, CD5 is present on B cells in B- chronic lymphocytic leukemia or Mantle Cell Lymphoma, both abnormal B cell malignant processes.

  CD23 expression is not consistent with Mantel cells as shown on the decision tree on the right.

  A monoclonal B-cell population (Kappa or Lambda predominant) with expression of CD19, CD20, CD23, and co-expression of CD5 is consistent with which of the following?

  A. A normal B cell
  B. Chronic lymphocytic leukemia
  C. Mantle cell lymphoma
  D. A mature T cell
  B. Chronic lymphocytic leukemia

• Question 117:

  The lactophenol blue mount reveals tiny, ovoid microconidia, arranged in a daisy-head pattern at the tip of a straight conidiophore. This appearance is characteristic of the mold form of Sporothrix schenckii. By moving the focus up and down

  in a microscopic preparation, delicate hair-like attachments may be observed for each conidium.

  The mold form of Coccidioides immitis produces delicate hyphae that break up into arthroconidia separated by empty cells, giving an alternatively staining appearance.

  The mold form of Blastomyces dermatitidis is characterized by the production of single, smooth microconidia, each borne on a single, thin conidiophore ("lollipops").

  The mold form of Histoplasma capsulatum is recognized by the production of large, echinulate macroconidia, appearing as a prickly surface.

  The ovoid microconidia arranged in a daisy-head pattern at the tip of a a straight conidiophore, observed in the photomicrograph on the right, is characteristic of which of the following dimorphic molds?

  A. Sporothrix schenckii
  B. Coccidioides immitis
  C. Blastomyces dermatitidis
  D. Histoplasma capsulatum
  A. Sporothrix schenckii

• Question 118:

  Alkaline phosphatase, or ALP, is present in kidneys, liver, intestines, bone, and the placenta. The liver makes the largest amount of ALP. Some of the conditions associated with increased levels of ALP include: damaged liver cells, rapid bone

  growth (during puberty), bone diseases, or a disease that affects how much calcium is in the blood (hyperparathyroidism), and vitamin D deficiency.

  Chemistry

  Isoenzymes of alkaline phosphatase occur in:

  A. Kidney, bone, intestines, liver
  B. Bone, brain, liver, pancreas
  C. Liver, brain, spleen, intestines
  D. Brain, kidney, intestines, bone
  A. Kidney, bone, intestines, liver

• Question 119:

  One of the key characteristics to the identification of Nocardia asteroides is its inability to hydrolyze casein, tyrosine or xanthine, as shown in this photograph. Nitrates are reduced to nitrites. Both Nocardia brasiliensis and Actinomadura madurae hydrolyze both casein and tyrosine; Streptomyces griseus hydrolyzes all three of the substrates.

  Illustrated in this photograph is an agar quadrant plate containing casein (A), tyrosine (B), nitrate (C) and xanthine (D). None of the substrates have been hydrolyzed and nitrate has been reduced. The most likely identification is:

  

  A. Nocardia asteroides
  B. Nocardia brasiliensis
  C. Streptomyces griseus
  D. Actinomadura madurae
  A. Nocardia asteroides

• Question 120:

  If all newborns were tested, many positive DATs due to ABO incompatibility would be detected that are of no clinical significance.

  Although many laboratories test infants born to group O Rh positive females due to the higher risk of ABO HDFN when the mother is group O, testing such infants is optional provided there is appropriate monitoring and follow-up for

  hyperbilirubinemia.

  Blood Bank

  Not performing direct antiglobulin tests (DATs) on newborns born to group O Rh positive mothers is acceptable good practice, providing there is appropriate surveillance and follow- up to detect hyperbilirubinemia.

  A. true
  B. false
  A. true
