A client newly diagnosed with eczema tells the clinic nurse of using a heat lamp to dry the fluid-filled blisters localized in the left antecubital area. How should the nurse respond?
Encourage the application of topical corticosteroids to eczema.
Explain the use of chemical debridement to reduce blistering.
Remind the client to restrict the use of heat to 15 to 20 minutes.
Provide a sling so the left arm can be extended and elevated.
The Correct Answer is A
Choice A reason: Topical corticosteroids reduce eczema’s inflammation by inhibiting cytokines, alleviating antecubital vesicles. Heat lamps dry skin, worsening irritation and cracking. Encouraging steroids addresses the inflammatory pathophysiology, promoting healing, making this the most effective response for managing eczema and correcting harmful self-treatment.
Choice B reason: Chemical debridement is for necrotic tissue, not eczema’s inflammatory vesicles. Heat lamps exacerbate dryness, but debridement does not address immune-mediated inflammation. Corticosteroids target the cytokine-driven process, making debridement inappropriate for eczema’s pathophysiology, which requires anti-inflammatory treatment.
Choice C reason: Restricting heat to 15–20 minutes does not mitigate harm, as heat dries eczema lesions, disrupting the skin barrier and increasing infection risk. Corticosteroids reduce inflammation, addressing vesicles. Heat worsens epidermal damage, making this response ineffective compared to targeting the inflammatory cause.
Choice D reason: A sling for arm elevation is irrelevant for localized eczema, an inflammatory dermatitis, not edema requiring elevation. Heat lamps aggravate dryness, and corticosteroids treat inflammation, addressing immune-mediated pathology more effectively than positional changes, which do not impact eczema’s skin symptoms.

Correct Answer is A
Explanation
Choice A reason: Yellow purulent drainage indicates wound infection, likely from bacterial proliferation (e.g., Staphylococcus aureus) causing pus. This serious complication risks delayed healing, abscess, or sepsis, necessitating provider notification for cultures, antibiotics, or surgical intervention. Infection disrupts tissue repair, requiring urgent management to prevent systemic spread or wound dehiscence.
Choice B reason: Pink granulation tissue is normal in wound healing, reflecting angiogenesis and fibroblast activity during the proliferative phase. It indicates healthy tissue formation, not requiring notification. Purulent drainage, however, signals infection, a critical issue disrupting healing and risking complications, making it the priority finding for reporting.
Choice C reason: Serosanguineous fluid, a mix of serum and blood, is expected in early surgical wounds as capillaries heal. It does not indicate infection unless excessive. Purulent drainage is more urgent, directly suggesting bacterial infection, which can lead to serious complications like sepsis, requiring immediate provider attention.
Choice D reason: Approximated wound edges indicate proper closure and healing, reducing scarring and infection risk. This positive finding does not warrant notification. Yellow purulent drainage, conversely, signals infection, a critical complication requiring urgent intervention to prevent further tissue damage or systemic infection, making it the priority.
Correct Answer is C
Explanation
Choice A reason: Placing the chair by the bed is preparatory but not immediate after sitting up. Prolonged bedrest risks orthostatic hypotension from reduced plasma volume and baroreceptor sensitivity. Assessing the client’s response ensures stability before transfer, preventing falls, making this less urgent than evaluating for dizziness or hypotension.
Choice B reason: Supporting the client when rising is premature before assessing their response to sitting. Bedrest causes deconditioning, increasing orthostatic hypotension risk, leading to dizziness or syncope. Determining how the client feels confirms cardiovascular stability, preventing falls during transfer due to blood pressure drops.
Choice C reason: Determining how the client feels assesses for orthostatic hypotension, common post-bedrest due to reduced venous return and baroreceptor dysfunction. Dizziness or lightheadedness signals syncope risk during transfer. This ensures cardiovascular stability, prioritizing safety before physical support, addressing physiological changes from prolonged immobility.
Choice D reason: Offering non-skid socks prevents falls during ambulation but is secondary to assessing sitting response. Bedrest heightens hypotension risk, and ensuring the client is not dizzy takes precedence to avoid syncope. Socks are a later safety measure, making this less immediate than evaluating physiological stability.
