The characteristic that distinguishes vancomycin-resistant Enterococcus faecium and Enterococcus faecalis from other Enterococcus species is their lack of motility.
Enterococci are all catalase-negative. Growth on bile esculin agar and in 6.5% salt broth are two characteristics that have commonly been used to identify Enterococcus to the genus level. A positive esculin in combination with a positive PYR reaction is another approach to presumptive identification.
Which one of these characteristics distinguishes vancomycin-resistant Enterococcus faecium and Enterococcus faecalis from other Enterococcus species?

A. PYR positive reaction

B. Non-motility

C. Growth on bile esculin agar

D. Catalase negative

出題：3

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:

A. carboxhemoglobin is formed

B. acid hematin is formed

C. ferrous iron is oxidized to ferric iron to form methemoglobin

D. iron remains in the ferrous state

出題：8

Hives and rash usually indicate an allergic reaction. Hematuria is due to a variety of causes. Fever and chills usually indicate a febrile reaction. Positive DAT due to conditions other than sensitization to red cell alloantigens is not uncommon. Therefore a positive DAT in the posttransfusion specimen with a negative DAT in the pretransfusion specimen is more likely to indicate alloimmunization.
The most definite indication that a patient has been sensitized to a specific red cell antigen is:

A. A positive posttransfusion DAT in a patient with a previously positive DAT

B. Hives and rash

C. A positive posttransfusion DAT in a patient with a previously negative DAT

D. Hemoglobinuria

A. a normal pH

B. normal p02 and pCo2 for normal respiration

C. correct bicarbonate level, since it is the most important system in the body

D. correct carbonic acid level, since it is the most important system in the body
