B) Topical antibiotic alone
C) Oral anticoagulation
D) No treatment because antivirals are ineffective after the rash appears

3.
An older adult develops a rapidly expanding erythematous area on the lower
leg accompanied by fever, warmth, swelling, and tenderness. Which
diagnosis is most likely?
,A) Cellulitis
B) Psoriasis
C) Vitiligo
D) Herpes zoster

4.
Which finding should raise the greatest concern for necrotizing fasciitis?
A) Mild pruritus
B) Severe pain out of proportion to the visible skin findings
C) Stable dry skin
D) Symmetric hyperpigmentation
Answer: B) Severe pain out of proportion to the visible skin findings
Rationale: Disproportionate pain, rapid progression, systemic toxicity,
bullae, and skin discoloration are important warning signs of necrotizing soft-
tissue infection.
5.
A 78-year-old patient has a chronic nonhealing ulcer near the medial
malleolus with lower-leg edema and brownish skin discoloration. Which
condition is most likely?
A) Chronic venous insufficiency
B) Acute arterial embolism
C) Herpes zoster
