Which of the following is a true statement about heart disease in older adults?

Question

Quizplus · Accepted Answer

Because the heart is an ineffective pump in HF,both excessive urination at night and decreased urination can occur when older adults have an MI.Nocturia occurs in HF when the heart is unable to maintain adequate renal blood flow in the performance of daily activities; then,during the night when the patient's lower extremities are elevated for sleep,the heart is able to perfuse the kidneys with the assistance of increased venous return owing to the elevated extremities.Inadequate urine production is due to inadequate perfusion from an ineffective pump.
The classic presentation of angina pectoris in older patients is often absent in what is known as a silent MI,with only mild discomfort,perhaps even limited to nausea or "heartburn" as the only symptom.Failure to engage in cardiac rehabilitation exercises is more likely to result in another MI or be an aggravation of HF than ordinary exertion.A person with HF is more likely to have difficulty breathing except when the trunk is upright (orthopnea).
