has a linear pattern. She reports recent exposure to poison ivy. Which condition is most likely?
,A. Contact dermatitis
B. Atopic dermatitis
C. Urticaria
D. Psoriasis
💫RATIONALE✔️✔️: Contact dermatitis caused by poison ivy presents as erythematous, pruritic
lesions in a linear pattern, reflecting contact with the plant. Atopic dermatitis is typically chronic and not

key distinguishing feature.
💫ANSWER✔️✔️: A. Contact dermatitis

B. "Apply a thick layer and cover with an occlusive dressing."
C. "Use the cream for at least 4 weeks."
D. "Apply the cream to the unaffected surrounding skin."
💫RATIONALE✔️✔️: Topical corticosteroids should be applied in a thin layer to the affected area as
