Which secondary skin lesions are associated with eczema?
Scales.
Erosion.
Crusts.
Ulcers.
Correct Answer : A,B,C
Choice A rationale
Scales represent the accumulation of dead skin cells that flake off, a common secondary lesion in eczema resulting from the chronic inflammation and rapid skin cell turnover.
Choice B rationale
Erosion occurs when the superficial layer of skin is lost, typically due to scratching or friction in eczema, exposing the underlying epidermis and sometimes leading to infection.
Choice C rationale
Crusts form when serum, blood, or purulent exudate dries on the skin surface, often seen in eczema as a result of weeping lesions and subsequent drying.
Choice D rationale
Ulcers are deeper lesions extending into the dermis or subcutaneous tissue and are not typically associated with eczema. Eczema usually affects the epidermis, causing secondary lesions like scales, erosion, and crusts rather than deep tissue ulcers.

Correct Answer is A
Explanation
Choice A rationale
The brain stem controls vital functions, including respiration. Damage to the brain stem, especially the medulla oblongata, can impair respiratory control, leading to the need for mechanical ventilation.
Choice B rationale
The parietal lobe is responsible for sensory processing and does not directly influence respiratory functions. Damage here would more likely affect sensation and spatial awareness.
Choice C rationale
The occipital lobe is primarily responsible for visual processing. Injury to this area would result in visual deficits rather than impaired respiration.
Choice D rationale
The frontal lobe is involved in cognitive functions, voluntary movement, and speech production, but it does not control respiration. Damage here would affect higher cognitive functions and motor planning.
Correct Answer is A
Explanation
Choice A rationale
Percutaneous absorption of topical corticosteroids increases systemic exposure, potentially causing side effects like adrenal suppression, hyperglycemia, and Cushing's syndrome. This is particularly significant when potent corticosteroids are applied to large body areas or under occlusive dressings, enhancing absorption and systemic effects.
Choice B rationale
Topical corticosteroids primarily induce vasoconstriction, not vasodilation, reducing inflammation and redness in skin conditions. Incorrect understanding of their vasodilatory effects may misguide nursing interventions, making it less relevant to the injury risk in atopic dermatitis treatments.
Choice C rationale
Topical corticosteroids have minimal systemic interactions compared to oral or intravenous forms, making drug interaction concerns less pertinent. The risk of significant drug interactions is low unless the medication is systemically absorbed in substantial amounts.
Choice D rationale
Application to face, neck, and intertriginous sites increases the risk of local side effects like skin atrophy, but is not a primary concern for systemic injury risk. These areas have thinner skin, enhancing absorption and risk of local adverse effects, but not necessarily systemic harm.
