ASSESSMENT QUESTIONS AND
VERIFIED ANSWERS |GRADE A+| JUST
RELEASED. CHAMBERLAIN
1. A 45-year-old male presents with a sudden onset of excruciating pain, redness, and
swelling in his right great toe. He mentions a heavy meal of steak and red wine the night
before. What is the definitive diagnostic gold standard for this condition?
A. Polarized light microscopy of joint aspirate showing negatively birefringent needle-
shaped crystals
B. Serum uric acid levels greater than 7.0 mg/dL
C. Plain film radiography showing ‘punched-out’ erosions
D. Presence of tophi on physical examination
Answer: A
Conceptual Explanation: The definitive diagnosis for gout is the identification of
monosodium urate crystals in synovial fluid using polarized light microscopy. Serum uric
acid can be normal during an acute attack.
2. When evaluating a patient with a sore throat, which of the following Centor criteria is NOT
used to determine the likelihood of a Group A Beta-Hemolytic Streptococcus infection?
A. Absence of cough
,B. Presence of rhinorrhea
C. History of fever
D. Tonsillar exudates
Answer: B
Conceptual Explanation: The Centor criteria include fever, tonsillar exudates, tender
anterior cervical adenopathy, and absence of cough. Rhinorrhea is more suggestive of a
viral etiology.
3. A 28-year-old female presents with a ‘herald patch’ on her back, followed by a widespread
‘Christmas tree’ pattern rash on her trunk. What is the most likely diagnosis?
A. Tinea corporis
B. Secondary syphilis
C. Pityriasis rosea
D. Guttate psoriasis
Answer: C
Conceptual Explanation: Pityriasis rosea typically begins with a single herald patch and
progresses to a symmetric distribution along skin cleavage lines (Christmas tree pattern).
4. A patient complains of a ‘curtain closing’ over their vision in the left eye, accompanied by
floaters and flashes of light. This presentation is most consistent with:
A. Acute angle-closure glaucoma
, B. Central retinal artery occlusion
C. Macular degeneration
D. Retinal detachment
Answer: D
Conceptual Explanation: Flashing lights (photopsia), floaters, and a sensation of a curtain
or shadow being pulled over the visual field are classic symptoms of retinal detachment.
5. A 60-year-old patient presents with a persistent, non-healing ulcerated lesion on the lower
lip that has a pearly border and telangiectasia. What is the most likely diagnosis?
A. Squamous cell carcinoma
B. Actinic keratosis
C. Basal cell carcinoma
D. Aphthous ulcer
Answer: C
Conceptual Explanation: Basal cell carcinoma is the most common skin cancer and often
presents as a pearly, waxy papule with telangiectasia and central ulceration.
6. In the management of community-acquired pneumonia (CAP) in a healthy adult with no
recent antibiotic use, which is currently recommended as a first-line outpatient treatment?
A. Vancomycin 1g IV
B. Levofloxacin 750mg daily
