PHYSICAL THERAPY IMPLICATIONS
Evaluation and Examination
Be alert for signs of hepatotoxicity, including anorexia, abdominal pain, severe nausea and vomiting, yellow skin or eyes, fever, sore throat, malaise, weakness, facial edema, lethargy, and unusual bleeding or bruising. Report these signs to the physician immediately.
Monitor signs of allergic reactions and anaphylaxis, including pulmonary symptoms (tightness in the throat and chest, wheezing, cough, dyspnea) or skin reactions (rash, pruritus, urticaria). Notify physician or nursing staff immediately if these reactions occur.
Monitor signs of neutropenia (fever, sore throat, signs of infection), thrombocytopenia (bruising, nose bleeds, and bleeding gums), or unusual weakness and fatigue that might be due to anemia. Report these signs to the physician.
Monitor signs of nephrotoxicity, including blood or pus in urine, decreased urine output, weight gain from fluid retention, and fatigue. Report these signs to the physician.
Monitor and report any muscle weakness, aches, or cramps that might indicate low potassium levels (hypokalemia).
Monitor injection site for redness and swelling. Report prolonged or excessive injection site reactions to the physician.
For patients who are medically able to begin exercise, implement appropriate resistive exercises and aerobic training to maintain muscle strength and aerobic capacity during cancer chemotherapy, or to help restore function after chemotherapy.
