The name of the rapid test seen in the image, often used to differentiate S.
pneumoniae from viridans streptococci, in which a drop of 10% deoxycholate
was placed on an area of growth, is:
A) Bile solubility test
B) Bile esculin hydrolysis
C) Optochin susceptibility test
D) Bacitracin susceptibility test - (answer)A) Bile solubility test
Which of the following describes the Westgard multi-rule R4S?
A) Four consecutive control data points are within ±1s
B) Four consecutive control data points are outside ± 2s
C) One data point is +2SD and a consecutive data point is -2SD
D) Two consecutive data points fall outside the mean four times - (answer)C)
One data point is +2SD and a consecutive data point is -2SD

Westgard R4S rule: this rule applies when the difference between the highest
and lowest result of a run exceeds 4 standard deviations (SD). For example, on
day one the control is at +2SD. On day two, the same control is at -2SD. This
rule detects random errors. The run is rejected.
Which tests will be abnormal in a patient with Fibrin Stabilizing factor
deficiency?
A) aPTT
B) 5 M urea clot solubility test
C) Factor XIII assay
D) Both 5 M urea clot solubility test and Factor XIII assay - (answer)D) Both 5 M
urea clot solubility test and Factor XIII assay
The following BEST describes serum hCG levels during pregnancy:
A) Rise in levels throughout pregnancy
B) Highest levels found at end of pregnancy
C) Rapid rise in levels during first trimester; slow decline and possible level-off
throughout remainder of pregnancy
D) Slow rise in levels during first trimester; rapid rise during second trimester;
slow decline during the third trimester - (answer)C) Rapid rise in levels during
, 3
first trimester; slow decline and possible level-off throughout remainder of
pregnancy
Feedback
hCG levels rise rapidly during the first trimester, then the levels start to decline
around week 16. The hCG levels slowly decrease and can level off during the
remainder of the pregnancy.
Which of the following is an example of a macroscopic urinalysis abnormality?
A) Glitter cells
B) Positive protein
C) Waxy casts
D) Red blood cell casts - (answer)B) Positive protein
Feedback
The macroscopic abnormalities are detected by the physical and chemical
portions of the urinalysis. Obtaining a positive protein during the chemical
portion of a urinalysis would be an example of a macroscopic abnormality.
The presence of glitter cells, waxy casts, and red blood cell casts could only be
determined by the microscopic examination of the urine sample.

Which bacterial species is most likely represented by the spreading, wrinkled,
non-hemolytic colony appearance as illustrated in the photograph?
A) Burkholderia pseudomallei
B) Pseudomonas aerginosa
C) Bacillus cereus
D) Listeria monocytogenes - (answer)A) Burkholderia pseudomallei
Which hemoglobin will be increased in delta-beta thalassemia?
A) Hb A
B) Hb A2
C) Hb F
D) Hb H - (answer)C) Hb F
Feedback
HbF is increased in delta-beta thalassemia. It is increased to 100% in delta-beta
thalassemia major.
In beta thalassemia HbA, a2ß2, is decreased or absent.
In delta beta thalassemia HbA2, a2d2, is decreased.
