Respiratory, Cardiovascular, Neurologic, and Musculoskeletal Symptoms

Key Takeaways

  • Dyspnea, chest pain, neurologic change, and sudden functional decline require rapid assessment because oncology patients are at risk for emergencies beyond routine treatment effects.
  • Respiratory symptoms may reflect infection, anemia, pulmonary embolism, effusion, pneumonitis, airway obstruction, or disease progression.
  • Cardiovascular symptoms can result from cardiotoxic therapy, thrombosis, electrolyte abnormalities, anemia, fluid overload, or ischemia.
  • Neurologic and musculoskeletal findings may indicate neuropathy, brain metastases, spinal cord compression, falls, fracture, myopathy, or severe fatigue.
  • Nursing priorities include safety, focused assessment, escalation, fall precautions, rehabilitation referral, education, and reassessment after interventions.

Respiratory, Cardiovascular, Neurologic, and Musculoskeletal Symptoms

Respiratory Assessment

Respiratory symptoms in oncology require focused triage because causes can be infectious, treatment-related, thrombotic, structural, or disease-related. Assess onset, work of breathing, oxygen saturation, respiratory rate, cough, sputum, fever, chest pain, wheeze, hemoptysis, orthopnea, activity tolerance, recent therapy, and baseline lung disease. New dyspnea during neutropenia may be pneumonia or sepsis. New cough after thoracic radiation or checkpoint inhibitor therapy may be pneumonitis. Sudden dyspnea with pleuritic pain or tachycardia may be pulmonary embolism.

Supportive nursing actions may include positioning, oxygen under protocol, vital signs, pulse oximetry, energy conservation teaching, infection precautions, and provider notification. Escalate dyspnea at rest, hypoxia, cyanosis, chest pain, hemoptysis, stridor, altered mental status, or rapidly worsening symptoms. In palliative settings, dyspnea care also includes fan therapy when appropriate, opioids as ordered, anxiety support, secretion management, and goals-of-care communication.

Cardiovascular Symptoms

Cancer patients have increased risk for venous thromboembolism, arrhythmias, cardiomyopathy, ischemia, hypertension, fluid shifts, and electrolyte-related changes. Some therapies can be cardiotoxic, including certain anthracyclines, HER2-directed agents, tyrosine kinase inhibitors, proteasome inhibitors, immune checkpoint inhibitors, radiation involving the heart, and high-dose therapy. Assess chest pain, palpitations, syncope, edema, weight gain, blood pressure trends, dyspnea, fatigue, medication adherence, and cardiac history.

Escalate chest pain, new severe shortness of breath, syncope, symptomatic hypotension, uncontrolled hypertension, new irregular rhythm with symptoms, unilateral leg swelling, or signs of stroke. Teaching includes reporting swelling, sudden weight gain, chest symptoms, calf pain, and shortness of breath; taking antihypertensives or anticoagulants as prescribed; and avoiding over-the-counter drugs or supplements that increase bleeding risk without team approval.

Neurologic Symptoms

Neurologic symptoms may come from brain metastases, spinal cord compression, chemotherapy-induced peripheral neuropathy, immune-related neurotoxicity, metabolic abnormalities, infection, medications, stroke, seizure, or paraneoplastic processes. Assess mental status, headache, vision, speech, strength, sensation, gait, bowel or bladder changes, seizure activity, pain pattern, falls, and treatment history. New back pain with weakness, numbness, saddle anesthesia, or bowel or bladder dysfunction is an emergency.

Confusion after cellular therapy or bispecific antibody therapy may signal neurotoxicity. Severe headache with thrombocytopenia raises concern for bleeding.

Peripheral neuropathy commonly causes numbness, tingling, burning pain, balance problems, fine motor difficulty, and fall risk. Nurses should assess function, not only sensation: Can the patient button clothes, drive safely, feel the floor, use stairs, or prepare food? Interventions include fall precautions, footwear advice, medication review, safety teaching, and referral to physical or occupational therapy.

Rehabilitation and Safety Planning

Functional symptoms need an interdisciplinary plan. Oncology rehabilitation can address strength, endurance, balance, range of motion, swallowing, cognition, lymphedema, neuropathy, and return-to-work needs. The nurse should screen for falls, home stairs, assistive device use, caregiver availability, driving safety, and ability to manage medications or equipment. Severe fatigue should not be dismissed as laziness. Patients may need anemia evaluation, medication adjustment, sleep support, nutrition intervention, depression screening, or pacing strategies.

Reassessment asks whether the plan improved actual function, not only whether the symptom score changed. Home safety needs should be revisited after every fall or near fall.

Musculoskeletal Function, Fatigue, and Falls

Musculoskeletal symptoms include arthralgia, myalgia, weakness, bone pain, cramps, steroid myopathy, deconditioning, fracture risk, and treatment-related osteoporosis. Bone metastases can cause pain, hypercalcemia, pathologic fracture, or spinal cord compression. Assess pain location, movement effect, neurologic changes, falls, gait, assistive devices, calcium symptoms, and activity tolerance.

Cancer-related fatigue is persistent and may not improve fully with rest. Evaluate anemia, sleep, pain, depression, medications, nutrition, endocrine problems, infection, and activity level. Education may include pacing, planned activity, energy conservation, sleep hygiene, and rehabilitation. Safety depends on reassessment: Did dyspnea improve? Is gait stable? Are neurologic signs progressing? Red flags need action, not reassurance.
