A nurse is collecting data from a client to determine their risk for cardiovascular disease. Which of the following findings should the nurse identify as a modifiable risk factor.

The clinical scenario requires identifying which cardiovascular risk factor can be altered through lifestyle or medical intervention. Cardiovascular disease risk assessment involves distinguishing between non-modifiable biological factors and modifiable behavioral or metabolic conditions to implement targeted risk reduction strategies. Choice A rationale Biological sex is a non-modifiable genetic risk factor determined at conception. Estrogen provides some premenopausal cardiovascular protection, but sex chromosomes and inherent hormonal profiles cannot be clinically altered or modified to reduce cardiovascular disease risks. Choice B rationale Family history of heart failure represents an unalterable genetic predisposition. Inherited cardiovascular traits and familial genetic mutations increase baseline risk for myocardial dysfunction but remain fixed parameters that cannot be modified by therapeutic interventions. Choice C rationale Advanced age is an unalterable chronological risk factor. Progressive vascular stiffening, endothelial dysfunction, and cumulative myocardial wear occur naturally over time, meaning chronological age cannot be modified or reversed by healthcare interventions. Choice D rationale Type 2 diabetes is a metabolic disorder that is modifiable through glycemic control, diet, exercise, and pharmacological therapies. Managing hemoglobin A1c levels directly mitigates accelerated atherosclerosis, microvascular damage, and macrovascular coronary complications.
