Which instruction should the nurse provide a client who was recently diagnosed with Raynaud’s disease?

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.

Choice A reason: Smoking exacerbates PAD via nicotine-induced vasoconstriction and endothelial damage, reducing blood flow and worsening atherosclerosis, especially post-MI. Cessation is critical to halt vascular damage, improve endothelial function, and prevent further MI or limb ischemia, addressing the primary pathophysiological driver of disease progression in this high-risk client.

Choice B reason: Reducing saturated fats and salt lowers LDL cholesterol and blood pressure, mitigating atherosclerosis in PAD and MI. However, smoking directly causes vasoconstriction and plaque progression, making cessation more urgent. Dietary changes are secondary, as nicotine’s immediate vascular effects pose a greater risk to perfusion and cardiovascular health.

Choice C reason: Trimming toenails short prevents injury in PAD, where poor perfusion impairs healing. However, smoking cessation is more critical, as nicotine’s vasoconstrictive effects directly reduce arterial flow, worsening ischemia. Nail care is a minor preventive measure compared to addressing smoking, the primary contributor to PAD’s pathophysiology.

Choice D reason: Applying a heating pad is contraindicated in PAD, as reduced sensation increases burn risk, and heat doesn’t improve arterial insufficiency. Smoking cessation is paramount, as nicotine exacerbates vasoconstriction, reducing blood flow and risking tissue necrosis. Cessation directly addresses PAD’s vascular pathology, making it the priority instruction.
