Correct Answer is C

Explanation

Explanation: The Auspitz sign refers to the appearance of tiny bleeding points when the scales on psoriatic plaques are removed or scraped. This sign is a characteristic feature of psoriasis and helps differentiate it from other skin conditions.

Incorrect choices: a. Moist, oozing skin lesions: Moist, oozing lesions are not typical of psoriasis. Psoriasis plaques are dry and scaly in nature.

b. Dark, hyperpigmented patches: Hyperpigmentation is not a characteristic feature of psoriasis. Psoriatic plaques are typically erythematous (red) with silvery-white scales.

d. Translucent, fluid-filled blisters: Translucent, fluid-filled blisters are not typically associated with psoriasis. This description is more consistent with a condition called pemphigus, not psoriasis.

Correct Answer is D

Explanation

Explanation: Adherence to prescribed treatment plans and attending follow-up appointments with healthcare providers are crucial for effectively managing psoriasis and preventing complications.

Incorrect choices: a. "Regularly scrubbing the affected areas to remove scaling." - Vigorous scrubbing can irritate the skin and worsen psoriasis symptoms. Gentle cleansing is recommended.

b. "Avoiding all forms of physical activity to prevent skin irritation." - Engaging in light physical activity is generally encouraged, as long as it does not exacerbate psoriasis symptoms.

c. "Using topical corticosteroids as needed without healthcare provider consultation." - It is essential for patients to follow their healthcare provider's instructions regarding the use of topical corticosteroids, as inappropriate or excessive use can lead to adverse effects.
