1-in a disc diffusion susceptibility test, which of the following can result
if discs are placed on the inoculated media and left at room temperature
for an hour before incubation ???
a-the antibiotic whould not diffuse into the medium resulting in no zone.
b-zones of smaller diameter would result
c-zones of larger diameter would result
d-there would be no effect on the final zone diameter
2-the stock culture needed fore quality control testing of motility is
a-salmonella typhimurium/E.coli
b-E.coli/pseudomonas aerogonosa
c-serratia marcescens /E.coli
d-shigella sonnei /E.coli
3-an unusual nomber of methicillin-resistant staphylococcus aureus
determined by the Kirby-Bauer method were isolated in the laboratory
in the past month.which of the following is the most likely explanation
a-incubation of the susceptibility plates at 35 C
b-deterioration of the methillin discs
c-inoculation of plates 10 minuts after standarizing of the inoculum
d-standarization of the inoculum to 0.5 McFarland turbidity standard
4- total leukocytes count=10,000/ml
NRBCs that are seen per 100 leukocytes =25
what is the correct lukocytes count ?
a- 2,000/ml
b-8,000/ml
c-10,000/ml
d-12,000/ml
5- hematochrit =20%
RBC=1,500,000/ML
Haemoglobin=6mg/dl
what is the mean corpuscular volume MCV ??
a-68 fl
b-75f l
c-115 fl
d-133 fl
6-what is the formula for calculating the unknown concentration based
on Beers law??
7-which of the following statements about ABO-haemolytic disease of newborn are true?
a-it usually requires an exchange transfusion
b-it can occur in the first born
c-it requently results in stillbirth
d-it is frequently seen in groupe O mothers
now...
-a ,b and c are correct
-only a and c are correct
-only d is correct
-all are correct
8-which immunoglobulin is associated with allergic reactions??
a-IgA
b-IgE
c-IgG
d-IgM
9-an RNA-containing virus is
a-HAV
b-HBV
c-CMV
d-HSV
