Red eye and common ophthalmic conditions
Primary care triage and referral decisions
Infection recognition and management
Inflammatory and allergic conditions
Benign versus serious skin lesions
Legal, ethical, and professional practice considerations
Patient education and follow-up planning*
INTRODUCTION
This exam assesses clinical reasoning in differential diagnosis and primary care decision-making. It evaluates
knowledge of common skin and eye conditions, symptom interpretation, treatment priorities, and referral
thresholds. Questions are written in multiple-choice format with scenario-based prompts to reflect real-world
ambulatory practice. The focus is on identifying likely diagnoses, selecting appropriate initial management,
and recognizing urgent findings that require escalation. Learners are expected to apply foundational theory,
clinical judgment, and professional standards to safe patient care. The exam rewards careful pattern
recognition, accurate triage, and sound evidence-based decision-making.*
SECTION ONE: QUESTIONS 1–100

sinus tracts. What is the most likely diagnosis?
A. Lipoma
B. Epidermoid cyst
C. Hidradenitis suppurativa
D. Lymphadenitis
🟢 Correct answer: C. Hidradenitis suppurativa
🔴 RATIONALE: Recurrent painful nodules in intertriginous areas with scarring and sinus tracts are classic for

. A child has intense scalp itching and visible nits attached to hair shafts. What is the best diagnosis?
A. Tinea capitis
B. Pediculosis capitis
C. Seborrheic dermatitis
D. Alopecia areata

diagnosis?
, A. Subconjunctival hemorrhage
B. Acute angle-closure glaucoma
C. Keratitis
D. Uveitis
🟢 Correct answer: A. Subconjunctival hemorrhage
🔴 RATIONALE: A painless, sharply demarcated red patch with preserved vision is typical of subconjunctival
hemorrhage.
. Which finding is most consistent with bacterial conjunctivitis?
A. Itching with watery discharge
B. Purulent discharge and eyelids stuck together
C. Severe photophobia and corneal opacity
D. Fixed mid-dilated pupil
🟢 Correct answer: B. Purulent discharge and eyelids stuck together
🔴 RATIONALE: Bacterial conjunctivitis often produces purulent drainage and matting of the eyelids.
. A patient reports bilateral itchy, watery eyes during pollen season. What is the most likely diagnosis?
A. Allergic conjunctivitis
B. Orbital cellulitis
C. Acute iritis
D. Endophthalmitis
, 🟢 Correct answer: A. Allergic conjunctivitis
🔴 RATIONALE: Itching and watery bilateral symptoms with allergen exposure strongly suggest allergic
conjunctivitis.
. A patient has a painful red eye, blurred vision, nausea, and a fixed mid-dilated pupil. What is the priority
diagnosis?
A. Episcleritis
B. Dry eye syndrome
C. Acute angle-closure glaucoma
D. Blepharitis
🟢 Correct answer: C. Acute angle-closure glaucoma
🔴 RATIONALE: This is a classic emergency presentation of acute angle-closure glaucoma requiring immediate
referral.
