During the course of chemotherapy, a patient reports inability to complete activities of daily living due to fatigue, weakness, and dyspnea on exertion. On room air, pulse oxygen is 96% at rest and 95% after activity. Which of the following is the nurse's BEST intervention?

While assessing for influenza is important, the patient's symptoms of fatigue and dyspnea are more likely related to chemotherapy effects or anemia rather than an acute viral infection. Influenza would typically present with additional symptoms such as fever and body aches, which are not mentioned here.

Teaching about bleeding precautions is often necessary in patients receiving chemotherapy due to potential thrombocytopenia, but it does not address the immediate symptomatology of fatigue and weakness. This intervention would not provide the patient with immediate relief or clarification regarding the cause of their current symptoms.

While an oxygen concentrator may be beneficial if the patient had significant hypoxia, their oxygen saturation levels at rest and after activity are relatively stable at 96% and 95%, respectively. Thus, this intervention does not address the underlying issues contributing to the patient's reported fatigue and dyspnea.
