- 11. Which of the following clinical features makes bacterial tonsillitis LESS likely? A. Temperature >39 B. Cough C. Age 5-10 years D. Tender lymphadenopathy E. Purulent tonsillar exudateB. Use Centor criteria ie. T >38, no cough, tender anterior cervical nodes, tonsillar swelling or exudate, 3-14yo = 1 score.
Score 0-1 = no culture, no Abx.
Score 2-3 = culture all, treat if +ve.
Score 4+ = culture and treat all. - 22. What is the most frequent cause of bacterial meningitis in neonates? A. Streptococcus pneumoniae B. Escherichia coli C. Staphylococcus aureus D.

- 64. Name the organism for these gram stain appearance in bacterial meningitis. C. Gram positive cocci in chainsStreptococcus agalactiae (S. pneumoniae classically in pairs or diplococci)
- 74. Name the organism for these gram stain appearance in bacterial meningitis. D. Gram negative cocciNeisseria meningitidis
- 84. Name the organism for these gram stain appearance in bacterial meningitis. E. Gram positive cocci in clustersWould be the gram stain appearance of Staphylococcus aureus, an which is an infrequent cause of CNS infection.
