The patient has diabetes mellitus and chronic obstructive pulmonary disease that has been treated with high-dose corticosteroids for the several years. Which dermatologic manifestations could be related to these systemic problems (select one that does not apply)?

Correct Answer: B

Rationale: The correct answer is B: Increased sweating. This is because high-dose corticosteroids commonly cause skin thinning, making it difficult for the skin to retain moisture and leading to decreased sweating. Alopecia (A), dry, coarse, brittle hair (C), and impaired wound healing (D) are all potential dermatologic manifestations of long-term corticosteroid use due to their effects on skin health and healing processes.

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: B

Rationale: The correct answer is B because a fresh partial-thickness wound may have hairs in the wound that do not pull out easily due to the injury affecting the hair follicles. This is important for ambulance personnel to understand as it helps in assessing the depth of the burn injury accurately. Choice A is incorrect as coagulated blood vessels are more characteristic of full-thickness wounds. Choice C is incorrect because partial-thickness wounds are typically painful. Choice D is incorrect as a brown and leathery appearance is more indicative of a full-thickness burn.

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.
