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.

Answer and Explanation

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 C

Explanation

Choice A reason: Dependence is not a primary concern with lithium, a mood stabilizer. Toxicity is critical due to lithium’s narrow therapeutic range, risking severe complications. Dependence is more relevant to other drugs, per psychopharmacology and lithium therapy education standards in nursing.

Choice B reason: Interactions are important but less urgent than toxicity, which can be life-threatening with lithium’s narrow therapeutic index. Toxicity education emphasizes monitoring blood levels to prevent harm, per psychopharmacology and patient safety protocols in lithium therapy teaching.

Choice C reason: Toxicity is the most critical adverse effect to teach, as lithium’s narrow therapeutic index risks severe complications like seizures or renal failure. Monitoring symptoms and blood levels ensures safety, per evidence-based psychopharmacology and patient education protocols for lithium therapy in nursing.

Choice D reason: Tolerance is not a significant issue with lithium, unlike toxicity, which is life-threatening due to its narrow therapeutic range. Teaching toxicity symptoms prioritizes patient safety, per lithium therapy management and psychopharmacological education standards in nursing practice.

A. Clear breath sounds on auscultation. B. Increased respiratory rate. C. Decreased oxygen saturation. D. Presence of wheezing.

Correct Answer is A

Explanation

Choice A reason: Clear breath sounds indicate effective suctioning, as it removes secretions obstructing the airway, improving ventilation. This aligns with the goal of endotracheal suctioning to maintain airway patency, ensuring adequate oxygenation and reducing infection risk, per critical care and respiratory management protocols in nursing practice.

Choice B reason: Increased respiratory rate suggests respiratory distress, indicating ineffective suctioning. Clear breath sounds confirm secretion removal, ensuring airway patency. A rising rate may reflect persistent obstruction or hypoxia, requiring further intervention, per respiratory assessment and critical care standards for endotracheal tube management in nursing.

Choice C reason: Decreased oxygen saturation indicates ineffective suctioning, as secretions likely remain, impairing oxygenation. Clear breath sounds confirm airway clearance, improving gas exchange. Low saturation requires immediate reassessment, per oxygenation monitoring and critical care protocols for clients with endotracheal tubes in nursing practice.

Choice D reason: Presence of wheezing suggests airway narrowing or persistent secretions, indicating ineffective suctioning. Clear breath sounds demonstrate successful secretion removal, ensuring unobstructed airflow. Wheezing requires further intervention, per respiratory assessment and airway management standards in critical care nursing for intubated clients.
