Questions: 12 Vhiteboard) A middle-aged adult is diagnosed with Class III (moderate) heart failure. In which way is Class III heart failure different from other classes of heart failure in the patient, according to the New York Association of Classification of Heart Failure? The patient with Class III (moderate) heart failure will be unable to carry out physical activities comfortably and short of breath at rest. The patient with Class III (moderate) heart failure will feel comfortable with ordinary physical activity. The patient with Class III (moderate) heart failure will have marked symptoms like fatigue, palpitations, or dyspnea while doing less-thannormal physical activities, but are fine at rest. The patient with Class III (moderate) heart failure will feel fatigue and palpitations but only with ordinary activity and some at rest as well.

The answer is the third one: The patient with Class III (moderate) heart failure will have marked symptoms like fatigue, palpitations, or dyspnea while doing less-than-normal physical activities, but are fine at rest.

Explanation for each option:

1. The patient with Class III (moderate) heart failure will be unable to carry out physical activities comfortably and short of breath at rest.

   • This description is more characteristic of Class IV heart failure, where patients experience symptoms even at rest.

2. The patient with Class III (moderate) heart failure will feel comfortable with ordinary physical activity.

   • This description fits Class I heart failure, where patients do not experience limitations during ordinary physical activity.

3. The patient with Class III (moderate) heart failure will have marked symptoms like fatigue, palpitations, or dyspnea while doing less-than-normal physical activities, but are fine at rest.

   • This is the correct description for Class III heart failure. Patients experience significant limitations in physical activity due to symptoms but are comfortable at rest.

4. The patient with Class III (moderate) heart failure will feel fatigue and palpitations but only with ordinary activity and some at rest as well.

   • This description is somewhat ambiguous but leans towards Class IV, where symptoms can occur even at rest, though it also mentions ordinary activity which is not typical for Class III.

Summary: Class III heart failure is characterized by marked limitations in physical activity due to symptoms like fatigue, palpitations, or dyspnea, but patients are comfortable at rest.
