A patient with heart failure has orthopnea, tachycardia, fatigue, and activity intolerance. How would the nurse explain the presence of these findings?
1. "You are not coping with your body's changing health.".
2. "Your body's protective mechanisms are malfunctioning.".
3. "You have not been following instructions on caring for yourself.".
4. "Your body is trying to maintain an adequate blood pressure and oxygen supply.".

Rationale 1: These findings are not related to the patient's coping mechanisms.
Rationale 2: The patient's inherent compensatory mechanisms are not malfunctioning, but instead continue to attempt to maintain homeostasis.
Rationale 3: These symptoms are not caused by the patient's noncompliance with instructions.
Rationale 4: The patient's compensatory mechanisms attempt initially to compensate for the falling blood pressure and oxygen levels. At the outset, these mechanisms are able to keep up with the body's demands. However, over the long term, they create bigger problems.
