A client with chronic gout reports pain in several joints and has tophi on the hands. The nurse develops a plan of care (POC) to manage the client’s gout based on which understanding of the underlying pathology of these manifestations?

Choice A reason: Tissue ischemia from vasospasm is associated with conditions like stroke, not multiple sclerosis (MS). MS involves immune-mediated demyelination of the central nervous system, causing exacerbations. Ischemia does not drive MS exacerbations, making this incorrect, as scarring of the myelin sheath is the hallmark pathological change.

Choice B reason: Destruction of norepinephrine receptors is unrelated to multiple sclerosis. MS exacerbations result from immune attacks on myelin, leading to scarred plaques that disrupt nerve conduction. Norepinephrine receptor issues may affect autonomic functions, but they are not part of MS’s pathophysiology, making this an incorrect choice.

Choice C reason: Multiple sclerosis exacerbations result from immune-mediated destruction and scarring (sclerosis) of the myelin sheath, forming plaques that impair nerve signal transmission. This causes neurological symptoms like weakness or sensory loss. Progressive demyelination and scarring are the core pathologic changes, aligning with MS’s clinical and histopathological features.

Choice D reason: Over-secretion of excitatory neurotransmitters may occur in epilepsy or neurotoxicity, not multiple sclerosis. MS exacerbations stem from myelin sheath scarring, disrupting nerve conduction, not neurotransmitter imbalances. This choice is incorrect, as it does not reflect the immune-driven demyelination central to MS’s pathological process.

Choice A reason: Decreased red blood cell count indicates anemia, which may cause fatigue or exacerbate ischemia but is not a direct marker of atherosclerosis. Angina results from arterial plaque buildup, driven by elevated LDL cholesterol. Low RBCs do not contribute to plaque formation, making this inconsistent with the diagnosis.

Choice B reason: Elevated LDL cholesterol is a primary risk factor for atherosclerosis, as it deposits in arterial walls, forming plaques that narrow coronary arteries, causing angina. In overweight smokers with stress, high LDL is a key driver of cardiovascular disease, directly supporting the pathophysiology of angina, per evidence-based lipid guidelines.

Choice C reason: Decreased triglycerides are not associated with atherosclerosis, which is driven by high LDL and low HDL. Triglycerides contribute to cardiovascular risk when elevated, but low levels do not cause angina. Elevated LDL is the critical lipid abnormality in this client’s angina due to coronary artery narrowing.

Choice D reason: Increased HDL cholesterol is protective against atherosclerosis, as it removes cholesterol from arteries, reducing plaque formation. Angina is associated with low HDL and high LDL. High HDL would mitigate, not cause, the client’s condition, making this inconsistent with the diagnosis of atherosclerosis-induced angina.
