PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Watch for seizures; notify physician immediately if patient develops or increases seizure activity.
Monitor signs of allergic reactions and anaphylaxis, including pulmonary symptoms (tightness in the throat and chest, wheezing, cough dyspnea) or skin reactions (rash, prurits, urticaria). Notify physician or nursing staff immediately if these reactions occur.
Assess muscle aches and joint pain (arthralgia) that may be caused by serum sickness. Notify physician if these symptoms seem to be drug related rather than caused by musculoskeletal injury or if muscle and joint pain are accompanied by allergy-like reactions (fever, rashes, etc.)
Monitor signs of eosinophilia (fatigue, weakness, myalgia) or leukopenia (fever, sore throat, signs of infection); report these signs to the physician.
Monitor injection site for pain, swelling, and irritation. Report prolonged or excessive injection site reactions to the physician.
Always wash hands thoroughly and disinfect equipment (whirlpools, electrotherapeutic devices, treatment tables, and so forth) to help prevent the spread of infection. Use universal precautions or isolation procedures as indicated for specific patients.
