QUESTION 312
Escherichia coli and Klebsiella pneumoniae are two good quality control choices for the indole test. E. coli is indole positive, while K. pneumoniae is indole negative. A positive reaction is noted when there is a red layer at the top of the tube after the addition of Kovács reagent, while the negative result is a lack of color change in the top of the tube after the addition of Kovács reagent.
Which one of the following combinations of organisms would be appropriate positive and negative controls to verify the specific test functions listed?

Which FAB designation is called the “true” monocytic leukemia and is characterized by monoblasts, promonocytes, and monocytes?

QUESTION 317
In an alkaline medium, potassium ferricyanide oxidizes hemoglobin to methemoglobin. Further reaction with potassium cyanide produces cyanmethemoglobin which has a maximum absorbance at 540 nm. Color intensity is proportional to total hemoglobin concentration, which is how the hemoglobin levels are measured.
Hematology
In the hemoglobin methodology using potassium ferricyanide the following measurable reaction occurs:

QUESTION 318
Enterobius vermicularis infection occurs through swallowing ova. Pinworm infections including those caused by Enterobius vermicularis, usually occur due to a fecal-oral route of transmission. According to the CDC,
“Eggs are deposited on perianal folds. Self-infection occurs by transferring infective eggs to the mouth with hands that have scratched the perianal area. Person-to-person transmission can also occur through handling of contaminated clothes or bed linens. Enterobiasis may also be acquired through surfaces in the environment that are contaminated with pinworm eggs (e.g. , curtains, carpeting). Some small number of eggs may become airborne and inhaled. These would be swallowed and follow the same development as ingested eggs.
Following ingestion of infective eggs, the larvae hatch in the small intestine and the adults establish themselves in the colon. The time interval from ingestion of infective eggs to oviposition by the adult females is about one month. The life span of the adults is about two months. Gravid females migrate nocturnally outside the anus and oviposit while crawling on the skin of the perianal area. The larvae contained inside the eggs develop (the eggs become infective) in 4 to 6 hours under optimal conditions . Retroinfection, or the migration of newly hatched larvae from the anal skin back into the rectum, may occur but the frequency with which this happens is unknown.” Enterobius vermicularis infection occurs through:

QUESTION 319
The morphologic characteristic(s) associated with the Chediak-Higashi syndrome is (are):

QUESTION 320
Stuart Prower factor, or factor X, would cause abnormal PT, aPTT, and dRVVT test results as factor X is part of the common coagulation pathway and therefore measured in both the PT and aPTT test. In the dRVVT test, factor X is directly activated in the test principle; therefore an abnormal result would be expected in this test as well if there was a deficiency in factor X.
What tests will be abnormal in a patient with Stuart-Prower Factor deficiency?

QUESTION 321
The renal threshold is the maximum amount of a substance that the kidney can prevent from entering into the urine.
UA & body fluids
The renal threshold is best described as:

QUESTION 322
Although any one of the answers might be considered correct, a report of gram-positive cocci in chains provides sufficient information without going beyond what the observation might allow. In off-the record conversation with the physician, a technologist might divulge that the picture is consistent with Streptococcus; however, enterococci may have a similar Gram stain appearance, potentially leading to the wrong choice of empiric antibiotic agents.

The image shows the Gram stain prepared from the positive blood culture. What is the MOST appropriate report?

QUESTION 327
Cryptococcus neoformans is the MOST likely identification of the encapsulated yeast in this question. C.
neoformans is urease +, and grows brown colonies on birdseed agar. In addition, India ink stain can also be used for Cryptococus spp. identification.
What is the MOST likely identification of an encapsulated yeast in a blood culture bottle from a patient with septicemia with the following additional culture information?:
Failure to produce germ tubes

All of the following are benefits of autologous donation except:

QUESTION 329
Malbranchia species share the production of alternate staining arthroconidia as a common feature with the mold form of Coccidioides immitis.
Both Geotrichum species and Trichosporon species produce rectangular-shaped arthroconidia; however, they are regularly rather than alternately staining. Additionally, the arthroconidia of Geotrichum may produce germ tubes from one corner and the arthroconidia of Trichosporon species may produce blastoconidia from adjacent corners, features not shared by either Malbranchia species or Coccidioides immitis.
The hyphae of Microsporum canis, as seen in direct KOH mounts of skin scales, may break up into arthroconidia; however, they are much narrower in dimension and do not share the alternate staining characteristics.
Microbiology
The hyaline saprobic fungus that has microscopic features similar to the mold form of Coccidioides immitis is:
