Q5: Which of the following is a bacterial infection that is often resistant to antibiotics?
A. Tinea pedis
B. MRSA (Methicillin-Resistant Staphylococcus Aureus) [CORRECT]
C. Onychomycosis
D. Verruca
Correct Answer: B
,3
Rationale: MRSA is a serious staph infection. Tinea pedis is a fungus. Onychomycosis is a nail
fungus. Verruca is a wart (virus).
Q6: A single-celled organism that can exist almost anywhere is a:
A. Virus
B. Fungus
C. Bacteria [CORRECT]
D. Parasite
Correct Answer: C
Rationale: Bacteria are single-celled. Viruses are subcellular. Fungi are plant-like organisms.
Parasites live on a host.
Q7: Which type of bacteria causes boils and carbuncles?
A. Streptococci
B. Staphylococci [CORRECT]
C. Diplococci
D. Bacilli
Correct Answer: B
Rationale: Staphylococci are pus-forming bacteria that grow in clusters and cause abscesses,

Q8: The bacteria that cause tetanus are classified as:
A. Cocci
B. Bacilli [CORRECT]
C. Spirilla
D. Diplococci
, 4
Correct Answer: B
Rationale: Tetanus is caused by Clostridium tetani, a bacillus (rod-shaped) bacteria. Spirilla are
spiral-shaped. Cocci are spherical.
Q9: A symptom of a local infection includes:
A. Fever
B. Vomiting
C. A pustule (pus-filled lesion) [CORRECT]
D. Headache
Correct Answer: C
Rationale: A local infection is confined to a specific area and presents with redness, heat, pain,
and swelling/pus. Systemic symptoms like fever (A) indicate a general infection.
Q10: Which of the following is an example of a viral infection?
A. Onychia
B. Onychomycosis
C. Herpes Simplex [CORRECT]
D. Paronychia
Correct Answer: C
Rationale: Herpes Simplex is a virus (cold sores). Onychomycosis is fungal. Onychia and
Paronychia are usually bacterial infections of the nail.
Q11: The primary purpose of using a hospital-grade disinfectant is to:
A. Clean the work surface
B. Kill pathogenic microorganisms [CORRECT]
