32. A laboratory report shows increased blood viscosity. Which physiologic consequence is most likely if arterial pressure does not change?

25. A client is diagnosed with peripheral artery disease. The nurse explains that the narrowed arterial lumen increases systemic vascular resistance and raises blood pressure. Which statement best describes this vascular change?
