SECTION 1: INFECTIOUS DISEASES AND DERMATOLOGICAL
CONDITIONS (Questions 1-30)
Question 1:
What is the etiology of herpes simplex virus infection?
A) Bacterial infection transmitted through respiratory droplets
B) Herpes virus contact with skin and mucous membranes; persists in latent form
in trigeminal nerve and other ganglia
C) Fungal infection of the skin and nails
D) Parasitic infection transmitted through contaminated water
Answer: B) Herpes virus contact with skin and mucous membranes; persists
in latent form in trigeminal nerve and other ganglia
Rationale: Herpes simplex virus is transmitted through direct contact with infected
skin or mucous membranes. After primary infection, the virus establishes latency
in sensory nerve ganglia, particularly the trigeminal nerve, and can reactivate
periodically.
Question 2:
What is the causative agent of Lyme disease?
A) Virus transmitted by mosquito bite
B) Spirochete Borrelia burgdorferi transmitted by tick bite
C) Bacteria transmitted through contaminated food
D) Parasite transmitted through water
Answer: B) Spirochete Borrelia burgdorferi transmitted by tick bite
,Rationale: Lyme disease is caused by the spirochete Borrelia burgdorferi, which is
transmitted to humans through the bite of infected Ixodes ticks. Early recognition
and treatment are essential to prevent complications.
Question 3:
Which of the following is a Stage 1 clinical manifestation of Lyme disease?
A) Oligoarticular arthritis
B) Meningitis and peripheral neuropathy
C) Papules that itch and burn
D) Cranial nerve palsies
Answer: C) Papules that itch and burn
Rationale: Stage 1 (early localized) Lyme disease typically presents with erythema
migrans, a characteristic skin lesion that appears as a papule that itches and burns.
This rash expands over days to weeks.
Question 4:
Which is a Stage 3 clinical manifestation of Lyme disease?
A) Erythema migrans rash
B) Flu-like symptoms
C) Oligoarticular arthritis
D) Meningitis
Answer: C) Oligoarticular arthritis
Rationale: Stage 3 (late) Lyme disease is characterized by oligoarticular arthritis,
typically affecting the knee or other large joints. This stage occurs months to years
after initial infection.
Question 5:
Alpha-gal syndrome is a condition transmitted by:
A) Mosquito bites
B) Tick bites
,C) Flea bites
D) Contaminated food
Answer: B) Tick bites
Rationale: Alpha-gal syndrome is a food allergy to red meat that develops after a
tick bite. The tick bite sensitizes the person to the alpha-gal sugar molecule found
in mammalian meat.
Question 6:
Scabies is caused by:
A) Bacterial infection
B) Sarcoptes scabiei mite
C) Viral infection
D) Fungal infection
Answer: B) Sarcoptes scabiei mite
Rationale: Scabies is a parasitic infestation caused by the Sarcoptes scabiei mite.
The female mite burrows into the stratum corneum to lay eggs, causing intense
pruritus.
Question 7:
What is the life cycle of the scabies mite?
A) Eggs are laid on the skin surface and hatch within hours
B) Eggs are laid in the stratum corneum, hatch into larvae, and mature to adulthood
in 3 to 4 days
C) Mites live in hair follicles and reproduce quickly
D) Mites are transmitted through the air
Answer: B) Eggs are laid in the stratum corneum, hatch into larvae, and
mature to adulthood in 3 to 4 days
Rationale: The female scabies mite burrows into the stratum corneum, lays eggs,
and the eggs hatch into larvae. The larvae mature into adults within 3 to 4 days.
Scabies is usually contracted through close personal contact.
, Question 8:
Which of the following is a clinical manifestation of scabies?
A) Large, erythematous plaques with silver scales
B) Small, erythematous papules, itching, and dry scale or crust around finger webs,
wrist, umbilicus, and groin
C) Painful vesicles on the face and trunk
D) Circular lesions with central clearing
Answer: B) Small, erythematous papules, itching, and dry scale or crust
around finger webs, wrist, umbilicus, and groin
Rationale: Scabies presents with small, erythematous papules, intense itching
(especially at night), and dry scale or crust. Characteristic locations include finger
webs, wrists, umbilicus, and groin area.
Question 9:
Pediculosis is:
A) A fungal infection of the scalp
B) Infestation with lice, transmitted by personal contact or common use of brushes,
combs, or headgear
C) A viral infection causing hair loss
D) A bacterial infection of the hair follicles
Answer: B) Infestation with lice, transmitted by personal contact or common
use of brushes, combs, or headgear
Rationale: Pediculosis is infestation with lice. It is transmitted through personal
contact or sharing of combs, brushes, headgear, or other personal items. It causes
intense pruritus.
Question 10:
What is the etiology of scleroderma?
