The physician orders Lanoxin elixir 80 mcg po daily for congestive heart failure. How many milliliters will the nurse administer? (LABEL CORRECTLY and Round to tenth)

Choice A reason: Walking promotes collateral circulation in peripheral vascular disease, improving blood flow and reducing claudication. Regular exercise strengthens muscles and enhances perfusion, mitigating ischemic symptoms. This is a key instruction, as it directly addresses arterial insufficiency, supporting functional status and cardiovascular health in affected clients.

Choice B reason: Knee-length stockings may restrict blood flow in peripheral vascular disease, especially arterial insufficiency, worsening ischemia. Compression is used for venous disease, not arterial. This instruction is incorrect, as it could exacerbate symptoms, requiring teaching on avoiding tight clothing to maintain circulation.

Choice C reason: Shopping for shoes in the morning is less relevant, as foot swelling in peripheral vascular disease occurs later in the day. Properly fitted shoes are important, but walking is a more direct intervention to improve circulation, making this a less critical instruction for managing the condition.

Choice D reason: Elevating legs is appropriate for venous disease to reduce edema but may worsen arterial insufficiency in peripheral vascular disease by reducing blood flow to extremities. Walking is preferred to enhance perfusion, making leg elevation an incorrect instruction for clients with arterial pathology.

Choice A reason: Atherosclerosis involves plaque buildup, not loss of elasticity, while arteriosclerosis is the general hardening of arteries, including elasticity loss. This reverses the definitions, making it incorrect, as the nurse must clarify that atherosclerosis is plaque-related and arteriosclerosis is broader vessel hardening.

Choice B reason: Both atherosclerosis and arteriosclerosis affect arteries, not veins. Atherosclerosis involves plaque, while arteriosclerosis includes any arterial hardening. This is incorrect, as it misidentifies the affected vessels, requiring correction to focus on arterial pathology for both conditions.

Choice C reason: Atherosclerosis is the buildup of plaque in arteries, causing narrowing, while arteriosclerosis is the general loss of arterial elasticity and hardening, including atherosclerosis. This is the correct distinction, accurately describing the difference in their pathological processes for the nurse’s understanding.

Choice D reason: Neither atherosclerosis nor arteriosclerosis is fully reversible, though lifestyle changes can slow progression. This is incorrect, as the distinction lies in plaque buildup (atherosclerosis) versus general hardening (arteriosclerosis), not reversibility, requiring clarification of their chronic nature.
