Unfolding Case Study

1.
c. The client’s blood pressure meets the criteria for hypertension, which is a systolic blood pressure greater than or equal to 129 mm Hg and/or a diastolic blood pressure greater than or equal to 80 mm Hg. Peripheral vascular disease causes blood return issues, while peripheral arterial disease will cause ischemia and blood flow restrictions. This client has symptoms of erectile dysfunction which can be directly related to the decreased blood flow caused by hypertension.
2.
a. An electrocardiogram evaluates the electrical function of the heart and can provide initial indication of heart disease or heart damage.
3.
c. Increasing fiber intake has several health benefits. It lowers cholesterol and blood pressure and decreases the risk of heart disease.
4.
d. A cheeseburger contains red meat and cheese, both of which contain saturated fats that contribute to heart disease.
5.
a. It appears that the changes are effective, as the client’s blood pressure is coming down. The goal of the diet is to reduce blood pressure and, secondarily, cholesterol levels. Cholesterol can be affected by much more than just diet, and it may take more than 3 months for levels to decrease.
6.
a. The client’s BMI was never an issue, so they do not have to lose a lot of weight. However, the client needed to lessen their waist size and is currently on track with that goal.
