The nurse calculates the body mass index (BMI) for an adult client who is obese. Which additional assessment finding places the client at high risk for cardiac disease?

Choice A reason: While high serum insulin levels can be indicative of insulin resistance and metabolic syndrome, they are not as directly related to cardiac risk as large waist circumference.Choice B reason: Hyperpigmentation on neck skin folds, also known as acanthosis nigricans, can indicate insulin resistance and metabolic syndrome but is not as strong a predictor of cardiac disease as central obesity.Choice C reason: Poor muscle tone is not a direct indicator of cardiac disease risk. It can be associated with overall health and fitness but is not as specific a risk factor for cardiac disease.Choice D reason: Large waist circumference with central fat, also known as abdominal obesity, is a well-known risk factor for cardiovascular disease. Central fat is associated with increased risk of heart disease, hypertension, and diabetes, making it a significant indicator to monitor.
