The nurse is caring for a patient with psoriasis and notices the presence of "Auspitz sign" during the assessment. What does this finding indicate?
Increased bleeding tendency in the patient.
Presence of skin pustules and blisters.
Formation of deep fissures in the skin.
Presence of pinpoint bleeding when scales are removed.
The Correct Answer is D
Explanation: Auspitz sign is a characteristic finding in psoriasis where pinpoint bleeding occurs when scales on the skin are removed. It is caused by the rapid growth and shedding of skin cells, which leads to the formation of delicate blood vessels that bleed easily.
Incorrect choices: a. Auspitz sign is not related to increased bleeding tendency in the patient; it is specific to psoriasis and its characteristic skin changes.
b. Presence of skin pustules and blisters is not associated with Auspitz sign and may indicate other skin conditions.
c. Formation of deep fissures in the skin is not directly related to Auspitz sign, which focuses on the bleeding after scale removal.

Correct Answer is C
Explanation
Explanation: Psoriasis commonly presents as red, scaly, and thickened patches on the skin. These patches can be itchy, painful, and sometimes crack and bleed.
Incorrect choices: a. Smooth and pink patches on the skin - This is not characteristic of psoriasis, which typically involves scaling and thickening of the skin.
b. Flaky, white patches on the skin - This is not typical of psoriasis; the patches are usually red and scaly.
d. Raised, flesh-colored bumps on the skin - This description does not match the typical appearance of psoriasis patches.
Correct Answer is D
Explanation
Explanation: A skin biopsy is commonly performed to confirm the diagnosis of psoriasis. It involves taking a small sample of skin tissue from a psoriatic plaque and examining it under a microscope to identify the characteristic histological changes, such as hyperkeratosis, parakeratosis, and elongation of the rete ridges.
Incorrect choices: a. Skin patch testing for allergens: Patch testing is used to diagnose allergic contact dermatitis, not psoriasis.
b. Chest X-ray to assess lung involvement: Chest X-rays are not necessary for the diagnosis of psoriasis, as it primarily affects the skin and joints, not the lungs.
c. Complete blood count (CBC) to assess white blood cell count: While a CBC may be performed to assess inflammation, it is not specific to psoriasis and cannot confirm the diagnosis. A skin biopsy is needed for definitive diagnosis.
