The objective of management of psoriasis is to

Correct Answer: D

Rationale: The correct answer is D: inhibit epidermal proliferation. Psoriasis is a chronic autoimmune condition characterized by rapid skin cell growth. Managing psoriasis involves inhibiting the excessive production of skin cells to reduce symptoms. Preventing infection (A), maintaining fluid and electrolyte balance (B), and reducing pain (C) are important considerations in overall patient care but do not address the root cause of psoriasis, which is the abnormal proliferation of skin cells. Therefore, the primary goal of management is to target epidermal proliferation to effectively control the disease.

Correct Answer: D

Rationale: The correct answer is D: the wound is infected. Redness around the edges, black spots, and green drainage are classic signs of infection. Redness indicates inflammation, black spots may be dead tissue, and green drainage suggests presence of bacteria. Infection delays healing and can lead to complications. It is crucial to identify and treat infections promptly to prevent further issues. Choices A, B, and C are incorrect because healing wounds typically show pinkish, not red, color; grafting readiness depends on other factors, not infection signs; and changing dressing method won't address the underlying infection issue.

Correct Answer: D

Rationale: The correct answer is D, which is vitamin D. Vitamin D is commonly referred to as the sunshine vitamin because our bodies can produce it when exposed to sunlight. It plays a crucial role in calcium absorption and bone health. Choice A (Vitamin A) is important for vision and immune function, but it is not the sunshine vitamin. Choice B (Vitamin B2) is also known as riboflavin and is involved in energy production, not sunlight production. Choice C (Vitamin C) is essential for immune function and skin health, but it is not the sunshine vitamin.

Correct Answer: D

Rationale: The correct answer is D: evaporation. When we sweat, the sweat on our skin evaporates, taking away heat from our body, thus helping to cool us down. This process is essential for regulating body temperature. Osmosis (A) is the movement of water across a semi-permeable membrane, not related to sweating. Conduction (B) is the transfer of heat through direct contact, not relevant to sweating. Condensation (C) is the process of gas turning into liquid, which is opposite to what happens during sweating.

Correct Answer: C

Rationale: The correct answer is C because free nerve endings are not specific to touch and pressure; they are responsible for detecting pain and temperature. The skin's accessory structures include hair, nails, and glands. A is incorrect as hair shafts are also living. B is incorrect as nail growth occurs from the nail matrix, not the root. D is incorrect as body hair does provide insulation. Hence, C is the only statement that does not accurately describe accessory skin structures.
