    Study Notes

    Assessment of Cardiovascular Health

    • A 70-year-old man exhibits a blood pressure of 140/100 mm Hg, heart rate of 104 beats per minute, and a split S2 heart sound, indicating an expected increase in systolic blood pressure due to aging.
    • Paroxysmal nocturnal dyspnea, which occurs with heart failure, is characterized by shortness of breath at night and is aggravated by lying down.
    • Major risk factors for heart disease include elevated serum cholesterol, elevated blood pressure, diabetes, obesity, smoking, and low activity level.
    • In infants, signs of heart disease during feeding include dyspnea, diaphoresis, and fatigue.
    • When assessing carotid arteries in a patient with cardiovascular disease, the nurse should auscultate for bruits and avoid compressing the artery to prevent an artificial bruit.
    • A blowing, swishing sound over the carotid artery with a stethoscope bell indicates blood flow turbulence, suggesting a valvular disorder.
    • Forceful movement of the chest along the sternal border during inspection of the precordium suggests right ventricular hypertrophy, while an apical impulse at the fourth or fifth intercostal space indicates normal heart function.
    • A 45-year-old man experiencing difficulty sleeping and waking up breathless may be exhibiting signs of paroxysmal nocturnal dyspnea, which is indicative of heart failure.
    • To assess for major risk factors of coronary artery disease, the nurse should collect data regarding elevated serum cholesterol, elevated blood pressure, diabetes, obesity, smoking, and low activity level.
    • Signs of heart disease in infants during feeding include dyspnea, diaphoresis, and fatigue.
    • When assessing carotid arteries, the nurse should auscultate for bruits and avoid compressing the artery to prevent an artificial bruit.
    • A blowing, swishing sound over the carotid artery with a stethoscope bell indicates blood flow turbulence, suggesting a valvular disorder.
