For the client, the emotional impact of psoriasis comes from

Correct Answer: C

Rationale: The correct answer is C) the threat to his self-image. Psoriasis is a chronic skin condition that can have a significant impact on a person's physical appearance, leading to feelings of embarrassment, self-consciousness, and low self-esteem. The emotional impact of psoriasis often stems from the visible nature of the condition, which can result in social stigma and negative perceptions from others. This can lead to psychological distress and a diminished quality of life for individuals living with psoriasis. Option A) its effect on the central nervous system is incorrect because while psoriasis is an immune-mediated condition, its emotional impact is more closely tied to the psychological and social aspects rather than direct effects on the central nervous system. Option B) the effects of the drugs used to treat the psoriasis is incorrect because while some medications used to treat psoriasis may have side effects, the emotional impact primarily arises from the visibility of the skin condition itself rather than the treatment modalities. Option D) the fear of dying is incorrect as psoriasis is not a life-threatening condition, and the emotional impact typically revolves around the challenges of managing a chronic skin condition rather than fear of mortality. In an educational context, understanding the emotional impact of psoriasis is crucial for healthcare professionals working with patients with this condition. By recognizing the psychosocial challenges faced by individuals with psoriasis, healthcare providers can offer holistic care that addresses not only the physical symptoms but also the emotional well-being of the patient. This knowledge can help improve patient outcomes and overall quality of life for individuals living with psoriasis.

Correct Answer: A

Rationale: The correct answer is A) partial-thickness. In this scenario, the burn described with intact large blisters, a broken blister, redness, and moisture indicates a partial-thickness burn. This type of burn affects the epidermis and part of the dermis layer of the skin, leading to blister formation and skin redness. Option B) first-degree burn only affects the epidermis and presents with redness and pain but no blister formation, which does not align with the described scenario. Option C) full-thickness burn would involve damage to the entire epidermis and dermis, leading to a dry, leathery appearance and less moisture compared to the description provided. Option D) third-degree burns extend through all skin layers and often appear charred or white, which is not consistent with the moist, blistering wound described. For educational context, understanding the depth of a burn is crucial in determining the appropriate first aid care and subsequent medical treatment. Recognizing the characteristics of different burn depths can help individuals provide timely and effective care to minimize complications and promote healing.

Correct Answer: C

Rationale: The correct answer is C: blister. Heat can cause separation of skin layers leading to fluid accumulation, forming a blister. A callus is a thickened area of skin due to pressure or friction, not fluid accumulation. A nevus is a mole or birthmark, not related to heat. A bubo is a swollen lymph node, not related to skin separation due to heat.

Correct Answer: C

Rationale: The correct answer is C, dermis. White blood cells play a crucial role in the immune system, primarily located in the blood and lymphatic system. The dermis contains a network of blood vessels and lymphatic vessels, making it a hub for white blood cells to travel and function effectively in immune responses. Choices A and B are incorrect as they are primarily related to skin layers rather than immune cell distribution. Choice D is incorrect as while white blood cells can be found in various tissues, the highest concentration is typically in the dermis due to its rich blood and lymph supply.

Correct Answer: B

Rationale: The correct answer is B because sunlight triggers the conversion of a precursor molecule in the skin, not a form of protein, into vitamin D. This process occurs in the skin when UV rays hit a compound called 7-dehydrocholesterol, converting it into vitamin D. Melanocytes produce melanin in response to UV exposure to protect the skin from damage caused by UV rays, making choice D true. Choices A and C are incorrect because UV rays can indeed cause mutations in skin cells and stimulate melanocytes to produce more melanin, respectively.
