Diagnostic Criteria:

- Diagnosis of psoriasis is primarily clinical, based on the characteristic appearance and distribution of skin lesions.

- Biopsy may be performed to confirm the diagnosis and rule out other skin conditions.

Questions on Diagnostic Criteria:

Correct Answer is B

Explanation

A viral skin condition resulting in fluid-filled blisters - Psoriasis does not result in fluid-filled blisters; it presents as red, scaly patches instead.

Correct Answer is C

Explanation

Raised, flesh-colored bumps on the skin - This description does not match the typical appearance of psoriasis patches.

Correct Answer is C

Explanation

Excessive sun exposure - Sun exposure may improve psoriasis symptoms in some people, but it is not the underlying cause of the condition.

Correct Answer is A

Explanation

Neck - Psoriasis can involve the neck area, but it is not the most common site of involvement.

Correct Answer is C

Explanation

Allergic reaction: While certain allergens may exacerbate psoriasis symptoms in some individuals, an allergic reaction is not the primary cause of psoriasis. The condition's pathophysiology is rooted in immune system dysfunction rather than allergic responses.

Correct Answer is A

Explanation

Eosinophils: Eosinophils are a type of white blood cell involved in immune responses against parasitic infections and allergic reactions. While they are important in certain immune processes, they are not the main players in psoriasis etiology.

Correct Answer is C

Explanation

Protective factors against developing psoriasis: Environmental factors are not protective against developing psoriasis. As an autoimmune condition, psoriasis is primarily influenced by genetic predisposition and immune system dysfunction, not by protective environmental factors.

Correct Answer is C

Explanation

Immune system functions independently of psoriasis development: This statement is incorrect. The immune system plays a central role in psoriasis etiology. The abnormal immune response is the driving force behind the development and progression of psoriasis.

Correct Answer is C

Explanation

Genetic factors impair the skin's barrier function: Psoriasis is not caused by a skin barrier dysfunction. The condition is characterized by immune system dysregulation and the subsequent inflammation and rapid skin cell turnover.

Correct Answer is B

Explanation

Thickened, hardened skin with deep cracks: This description is more typical of a condition called lichenified eczema or chronic contact dermatitis, not psoriasis.

Correct Answer is A

Explanation

Upper arms and neck: Psoriasis can occur on the upper arms and neck, but it is not the most frequently affected area.

Correct Answer is C

Explanation

Excessive thirst and frequent urination: These symptoms are not typically related to psoriasis. They may be indicative of diabetes or other medical conditions.

Correct Answer is D

Explanation

Psoriasis lesions commonly appear in a symmetrical pattern, affecting similar areas on both sides of the body. For example, if a plaque is present on the right elbow, there is a high likelihood of a corresponding plaque on the left elbow.

Correct Answer is D

Explanation

Chronic psoriasis is characterized by thickened, scaly plaques with silvery-white scales. These plaques result from the excessive growth and turnover of skin cells in psoriasis.

Correct Answer is C

Explanation

Elevated erythrocyte sedimentation rate (ESR) on blood test: An elevated ESR can indicate inflammation in the body, but it is not specific to psoriasis and may be present in other inflammatory conditions as well.

Correct Answer is C

Explanation

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

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.

Correct Answer is C

Explanation

No explanation

Correct Answer is C

Explanation

Pustular psoriasis: Pustular psoriasis is a specific subtype characterized by pustules on the skin, but it is less common than plaque psoriasis.

Correct Answer is A

Explanation

While warm baths can be soothing, frequent baths may actually dry out the skin and worsen psoriasis. Additionally, the water should be lukewarm rather than hot to avoid triggering flare-ups.

Taking long, hot baths can actually worsen psoriasis by drying out the skin and triggering flare-ups. Instead, patients with psoriasis should take short, lukewarm baths or showers to avoid exacerbating the condition.

Phototherapy does not increase the risk of skin infections. However, patients with psoriasis should practice good hygiene to prevent infections related to their condition and skin care routine.

Topical retinoids can increase the skin's sensitivity to sunlight and may cause sunburn. Patients should avoid excessive sun exposure and use sunscreen to protect their skin when using topical retinoids.

Discontinuing immunosuppressive medications abruptly can be dangerous and should only be done under the guidance of a healthcare provider. Sudden discontinuation can lead to worsening of psoriasis and potential rebound effects.

"Expose your skin to direct sunlight for prolonged periods to improve symptoms." - While some sunlight exposure may benefit psoriasis, prolonged and direct exposure can lead to skin damage and increase the risk of skin cancer. Sun exposure should be limited and done with caution.

"Regularly use alcohol-based hand sanitizers to prevent infections." - Alcohol-based hand sanitizers can dry out the skin and may irritate psoriasis lesions. It is better to use gentle, non-irritating handwashing techniques.

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

"Use scented moisturizers for a pleasant fragrance." - Scented moisturizers may contain ingredients that can irritate the skin and trigger flare-ups. Unscented or fragrance-free moisturizers are recommended.

"Frequent application of alcohol-based hand sanitizers." - Alcohol-based hand sanitizers can dry out the skin and may irritate psoriasis lesions. It is better to use gentle, non-irritating handwashing techniques.More questions

This statement is correct. Treatment for psoriasis aims to reduce inflammation and slow down the rapid skin cell growth to manage the symptoms of the condition.

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.

MRI is not a diagnostic tool for psoriasis. It may be used in certain cases to assess joint involvement in psoriatic arthritis, but it does not diagnose psoriasis itself.

Psoriasis is not a type of skin cancer. It is a benign skin condition that does not involve the malignant transformation of melanocytes.

Ulcerated and bleeding skin sores are not typical of psoriasis. Psoriasis lesions are characterized by dry, scaly plaques rather than open sores.

Sun exposure can affect psoriasis, but it is not the primary factor contributing to its development. In some cases, moderate sunlight exposure may even improve psoriasis symptoms.

<p>Moisturizing the skin is essential for managing psoriasis and preventing dryness and scaling. Regular use of moisturizers helps maintain skin hydration and reduce the discomfort associated with psoriasis.</p>

<p>Urinalysis is not used to diagnose psoriasis, as it does not provide relevant information about the skin condition.</p>

<p>Smoking is associated with increased severity and risk of psoriasis, and quitting smoking can help improve symptoms.</p>

<p>Purple or red lumps under the skin are more suggestive of other conditions, such as nodules or hematomas, rather than psoriasis.</p>

<p>Any age, as it is random - Although psoriasis can appear at any age, there is a higher prevalence of onset during adolescence and young adulthood.</p>
