Remove all clothing and jewelry from the affected extremities **✔ 정답** 3. Administer prescribed antihistamine medication 4. Educate the client about avoiding future plant contact **정답: 2** ## 해설 The first priority is to remove clothing and jewelry to prevent further spread of plant oils like urushiol. Other interventions are supportive but secondary to decontamination. ## 심화 해설 Understanding the Priority: Safety and Exposure Control When a client presents with a contact dermatitis-type reaction, the immediate physiological threat is the continued exposure to the offending agent. The rash is a visible manifestation of an inflammatory response, but the substance causing it—likely an oleoresin or plant-derived chemical—can remain on the skin, embedded in clothing, or trapped under jewelry. In the context of NCLEX-RN priority setting, the first step is always to remove the causative agent to prevent the progression of injury. This principle is a direct application of the safety and infection control framework, which takes precedence over symptomatic relief or education. Pathophysiological Rationale and Clinical Application The scenario describes a localized inflammatory response, but the underlying principle of removing the antigen is identical to managing more severe cutaneous adverse reactions. The provided case report on Toxic Epidermal Necrolysis (TEN) illustrates the extreme end of this spectrum, where exposure to a chemical agent (DCT) triggered a devastating, widespread detachment of the epidermis involving 60% body surface area (BSA) [1]. While this client’s presentation is far less severe, the initial nursing action is conceptually identical: stop the assault on the skin. The allergen on the clothing and jewelry acts as a reservoir, continuously releasing the triggering substance onto the skin. By removing these items, the nurse physically eliminates the source of the inflammatory cascade, halting the progression of the rash from a localized reaction to a potentially more extensive one. This action is foundational before any topical or pharmacological intervention can be effective. Why Other Interventions Are Deferred Applying a cool compress (Option 1) provides symptomatic relief by causing vasoconstriction and reducing local pruritus, but it does not address the ongoing exposure if the antigen remains on the skin or clothing. Administering an antihistamine (Option 3) is a systemic pharmacological approach to block histamine receptors and reduce itching, yet it is a secondary measure that will have no effect on the external reservoir of the irritant. Patient education (Option 4) is a crucial psychosocial and health promotion component, but it is a long-term preventive strategy, not an immediate physiological priority during the acute exposure phase. The nursing process dictates that assessment and intervention to ensure physical safety must occur before comfort measures or teaching. The TEN case reinforces that the foundation of care begins with controlling the source of the skin injury, followed by supportive and pharmacological therapies [1].References (research sources) - [1]Toxic epidermal necrolysis induced by exposure to S,S-dimethyl cyanoimidodithiocarbonate: case report and nursing experience.Case reportLiu XQ, Dong XL, Qian YT, Shu C.

The immediate concern is ongoing exposure to the plant allergen. First-Line Nursing Action The priority intervention is to **remove all clothing and jewelry from the affected extremities**. Textiles and metal items act as reservoirs, trapping plant oleoresins (e.g., urushiol) and perpetuating skin contact. This stops the inflammatory cascade at its source and is a cornerstone of safety and exposure control. Stepwise Management Protocol - **Immediate Decontamination:** Remove contaminated items carefully to avoid spreading the allergen to unaffected skin. Double-bag items if the allergen is known to be potent. - **Skin Cleansing:** Wash the affected area with mild soap and copious lukewarm water to remove residual lipophilic plant oils. Avoid hot water, which can increase pruritus. - **Symptomatic Relief:** Apply cool, wet compresses or calamine lotion to reduce itching and inflammation. Administer prescribed oral antihistamines or topical corticosteroids as ordered. - **Patient Education:** Once the acute episode is controlled, educate on identifying hazardous plants, wearing protective clothing, and immediate washing after potential exposure. Nursing Considerations Monitor for signs of secondary bacterial infection (increased pain, purulent drainage, fever). Assess the extent of the rash and document its progression. In severe cases involving facial swelling or respiratory difficulty, prioritize airway management and prepare for emergency intervention. ## 핵심 개념 - **Contact Dermatitis** — An inflammatory skin condition caused by direct contact with an irritant or allergen, manifesting as a red, itchy rash. - **Allergen Reservoir** — A source, such as contaminated clothing or jewelry, that continuously releases an allergy-causing substance onto the skin, prolonging exposure. - **Priority Setting** — A nursing framework that dictates the order of interventions based on immediate threats to safety, airway, breathing, or circulation, often placing exposure removal first. ## 같은 주제 문제 - [A nurse is assessing a client who reports exposure to poison ivy 24 hours ago.
