Question

Quizplus · Accepted Answer

The symptoms described suggest that the patient is experiencing activity intolerance, which is defined as insufficient physiological or psychological energy to tolerate or complete necessary or desired activities. The patient's chemotherapy treatment can cause anemia, which can contribute to fatigue, pallor, and weakness; exertional dyspnea can also suggest anemia or cardiotoxicity from the chemotherapy medication. Headache and tachycardia can be signs of anemia, dehydration or electrolyte imbalances, and are further evidence of the patient's inability to tolerate activity. Therefore, addressing the underlying physiological condition of anemia and implementing measures to improve the patient's tolerance for activities of daily living should be the priority.
