QUESTIONS AND ANSWERS 2026
A newborn infant has a WBC count of 37,000/ul with the differential count
revealing the presence of 50 nRBCs per 100 WBCs. What is the corrected WBC
count?
15,000/ul
24,700/ul
27,300/ul
12,500/ul - correct-answer - B. 24,700/ul
Feedback Corrected WBC count= Uncorrected WBC count x100/nRBCs+100: Thus,
(37,000ulx100/50+100= 24,700ul)

Gram positive bacilli; non-motile; non-hemolytic; catalase positive; spore forming:
B. anthracis
B. cereus
N. meningitidis
N. lactamica - correct-answer - B. B. anthracis
Feedback Important distinguishing characteristics between B. anthracis and B.
cereus is motility, B. anthracis is non motile while B. cereus is motile.
Hair perforation test/Hair baiting test is for identification of which two fungi?
Aspergillus niger and A. japonicus
Tinea pedis and T. corporis

Trichophyton mentagrophyte and T. rubrum
C. albicans and C. tropicalis - correct-answer - C. Trichophyton mentagrophyte
and T. rubrum
Feedback Trichophyton mentagrophyte is positive and T. rubrum is negative
What is the minimum platelet count before you perform apheresis?
500
200
150
250 - correct-answer - C. 150.
, 4|Page
Feedback Apheresis donors with low normal pre-procedure platelet counts (150 -
200 x 10 9/L) and Hb concentration (12.5 - 13 g/dL) should be examined for post-
donation drops in these haematological parameters
Gram negative bacteria, normally found in the oropharyngeal tract of mammals,
they are involved in the pathogenesis of some animal bite wounds as well as
periodontal diseases. This bacteria exhibits GLIDING MOTILITY:
Leptospira
Actinobacillus
Capnocytophaga
Chlamydia - correct-answer - C. Capnocytophaga
Feedback The term Capnocytophaga comes from "Capno" for its dependence on
CO2 and "cytophaga" for its flexibility and mobility shift (" gliding motility ").
