Nursing Clinical Practice Guide
Clinical Scenario
Mr. Johnson, a 68-year-old former shipyard worker, is admitted with a confirmed diagnosis of stage IV non-small cell lung cancer. He reports a 2-week history of severe, constant pain in his mid-back and ribs, rated 8/10. He is fatigued, confused at times, and complaining of nausea and excessive thirst. His serum calcium comes back at 13.2 mg/dL.
Nursing Intervention Strategy
1. Assessment: Perform a comprehensive pain assessment using PQRST. Perform a focused neurological assessment (Glasgow Coma Scale (GCS), orientation). Monitor vital signs closely for bradycardia or arrhythmias. Assess for signs of fracture with gentle movement. Strict intake and output (I&O) monitoring.
2. Nursing Diagnosis: Acute Pain related to bone metastasis; Risk for Injury related to hypercalcemia-induced confusion and potential pathological fractures; Deficient Fluid Volume related to polyuria from hypercalcemia.
3. Planning & Implementation:
* Pain Management: Administer prescribed analgesics (often opioids) on a scheduled basis, not PRN, for constant pain. Consider adjuvant medications like NSAIDs or bisphosphonates as ordered.
* Hypercalcemia Management: Initiate IV hydration with 0.9% normal saline as ordered (often 200-300 mL/hr) to promote calciuresis. Administer IV bisphosphonates (e.g., zoledronic acid) slowly, monitoring for flu-like symptoms and renal function. Encourage oral fluids if able.
* Safety: Implement fall precautions: bed in low position, call bell within reach, non-slip footwear. Assist with ambulation. Reorient the patient as needed.
* Collaboration: Prepare for possible radiation therapy to painful bony sites for palliative pain control.
Patient Safety and Precautions
* Key Point! Bisphosphonates (zoledronic acid) can cause nephrotoxicity. Ensure adequate hydration before and during infusion. Monitor BUN and creatinine.
* Rapid correction of hypercalcemia can lead to electrolyte imbalances. Monitor for signs of fluid overload during aggressive hydration, especially in patients with cardiac or renal history.
* Handle the patient gently. Avoid twisting or heavy lifting that could cause a pathological fracture in weakened bones.
Nursing Procedure & Medication Flow
Administering IV Bisphosphonate for Hypercalcemia:
1. Verify order and check renal function (creatinine clearance).
2. Ensure patient is well-hydrated (often with a pre-infusion saline bolus).
3. Administer drug via IV infusion over at least 15 minutes (zoledronic acid) as per protocol. Never give as a bolus.
4. Monitor vital signs during infusion.
5. Educate patient that flu-like symptoms (fever, myalgia) may occur 24-48 hours post-infusion and are usually self-limiting.
A Word from Your Senior Nurse
"Oncology nursing requires you to be a detective and a compassionate caregiver. A complaint of 'back pain' in a lung cancer patient isn't just musculoskeletal—it's a red flag for metastasis until proven otherwise. Your thorough assessment and quick recognition of complications like hypercalcemia can prevent a crisis. When you see that lab value, think: Fluids, Safety, Pain. Connect the pathophysiology (tumor in bone → calcium release) to your nursing actions (hydrate, prevent falls, medicate for pain). This holistic, critical thinking is what makes an excellent nurse, both on the NCLEX and at the bedside."
