Fatigue on exertion that occurs in impaired cardiac function would be regarded as A. resistance failure B. sympathetic failure C. cardiovascular centre failure D. backward failure E. forward failure<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is E. forward failure<\/strong>.<\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n Fatigue on exertion is a common symptom of heart failure, which occurs when the heart is unable to pump blood effectively to meet the body’s demands. This condition can be classified into two types: forward failure<\/strong> and backward failure<\/strong>.<\/p>\n\n\n\n Forward failure<\/strong> occurs when the heart’s ability to pump blood to the organs and tissues is compromised. This leads to a reduced supply of oxygen and nutrients to the body during physical activity, resulting in fatigue. As the heart cannot pump blood efficiently, less oxygen-rich blood reaches the muscles and tissues, causing exhaustion even with minimal exertion. Symptoms like fatigue are usually more pronounced during physical activity because the body requires more oxygen during exertion, and the failing heart cannot deliver it effectively.<\/p>\n\n\n\n On the other hand, backward failure<\/strong> refers to the inability of the heart to properly pump blood out of the heart. This causes blood to back up into the lungs or other parts of the body, leading to symptoms such as pulmonary congestion or edema. While backward failure can also contribute to fatigue, it is usually associated with more severe symptoms like shortness of breath, fluid retention, and swelling.<\/p>\n\n\n\n In contrast to sympathetic failure<\/strong> or cardiovascular center failure<\/strong>, which may refer to issues within the autonomic nervous system or the brain’s regulatory mechanisms, forward failure<\/strong> is a direct consequence of impaired cardiac function where the heart is unable to meet the metabolic demands of the body.<\/p>\n\n\n\n Overall, fatigue on exertion in the context of impaired cardiac function is a classic sign of forward failure<\/strong>, highlighting the heart’s reduced capacity to pump sufficient blood during physical activity.<\/p>\n","protected":false},"excerpt":{"rendered":" Fatigue on exertion that occurs in impaired cardiac function would be regarded as A. resistance failure B. sympathetic failure C. cardiovascular centre failure D. backward failure E. forward failure The correct answer and explanation is: The correct answer is E. forward failure.
