A nurse is caring for a 55-year-old female client who underwent debulking surgery for stage IIIC ovarian cancer 3 days ago. The client is scheduled to begin chemotherapy with carboplatin and paclitaxel. Which nursing intervention should be the priority before initiating chemotherapy?

The client reports feeling anxious about starting chemotherapy and asks about potential side effects. Her current vital signs are stable, and laboratory results show WBC 6,500/mm³, hemoglobin 10.2 g/dL, and platelet count 180,000/mm³.
해설
Assessing baseline neurological function is the priority before carboplatin/paclitaxel chemotherapy due to high risk of paclitaxel-induced peripheral neuropathy. Obtaining consent, antiemetics, and dietary review are important but not initial priorities for neurotoxicity monitoring.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention before initiating a specific chemotherapy regimen. The client is scheduled for carboplatin and paclitaxel, a common first-line regimen for ovarian cancer. A critical, dose-limiting side effect of paclitaxel is peripheral neuropathy. Neuropathy can manifest as numbness, tingling ("pins and needles"), pain, or weakness in the hands and feet. Establishing a Key Point! baseline neurological assessment before the first dose is essential. This baseline allows the healthcare team to objectively monitor for the onset or worsening of neuropathic symptoms during and after treatment, guiding decisions about dose modifications or supportive care to prevent permanent nerve damage. Answer Rationale: Key Point! Assess baseline neurological function and document findings is the priority. Paclitaxel-induced neuropathy is common and can significantly impact the patient's quality of life and ability to perform activities of daily living (ADLs). A thorough baseline assessment (e.g., checking sensation, reflexes, grip strength, gait) provides critical reference data. Without this baseline, it is impossible to determine if new symptoms are treatment-related. This intervention directly addresses patient safety and the prevention of long-term complications. Distractor Analysis:
Watch out for confusion! Option ② (Administer antiemetic medications prophylactically): While nausea and vomiting are common side effects, antiemetics are typically administered just before or with the chemotherapy infusion, not as the priority assessment before initiating it. The question asks for the priority intervention "before initiating chemotherapy."
Option ③ (Obtain informed consent for chemotherapy treatment): Informed consent is a fundamental legal and ethical requirement. However, it is obtained by the prescribing physician before the treatment plan is finalized and the patient is scheduled. By the day of the first infusion, consent should already be documented. It is not the nurse's priority action immediately pre-infusion.
Option ④ (Review dietary restrictions and nutritional guidelines): This is an important component of patient education and supportive care to manage side effects like mucositis or taste changes. However, it does not take precedence over establishing a safety baseline for a high-risk, potential side effect. Related Concepts: Other key pre-chemotherapy assessments include verifying blood counts (to ensure the patient is not neutropenic, anemic, or thrombocytopenic), renal function (especially for carboplatin dosing, which is based on glomerular filtration rate (GFR)), and liver function. Patient education about all potential side effects (myelosuppression, alopecia, hypersensitivity reactions) is also crucial but follows initial safety assessments. Concept Summary
ConceptKey Points
Paclitaxel (Taxol)Taxane chemotherapy. Major side effects: Peripheral neuropathy, myelosuppression, alopecia, hypersensitivity reactions (requires premedication with steroids & antihistamines).
CarboplatinPlatinum-based chemotherapy. Major side effects: Myelosuppression (especially thrombocytopenia), nephrotoxicity, ototoxicity.
Pre-Chemotherapy Nursing Priorities1. Baseline assessment for specific drug toxicities (e.g., neuro for paclitaxel, hearing for cisplatin).
2. Verify lab values are safe for treatment.
3. Confirm patient identification, drug, dose, rate (rights of medication administration).
4. Administer prescribed premedications.
Peripheral Neuropathy AssessmentAssess for paresthesia (tingling), numbness, pain, loss of sensation, weakness. Check deep tendon reflexes, vibration sense, gait, and fine motor skills (buttoning). Use standardized tools like the Common Terminology Criteria for Adverse Events (CTCAE).
Side-by-Side Comparison!
Chemotherapy AgentKey Toxicities to Assess BEFORE First DosePriority Nursing Intervention
Paclitaxel / Docetaxel (Taxanes)Peripheral Neuropathy, Baseline Liver Function (metabolism)Comprehensive neurological exam; document baseline sensation, reflexes, motor function.
Cisplatin / Carboplatin (Platinum agents)Renal Function (Cr, GFR), Hearing (for Cisplatin)Verify creatinine clearance/GFR for dosing; baseline audiogram for cisplatin.
Doxorubicin (Anthracycline)Cardiac Function (Ejection Fraction)Ensure baseline echocardiogram or MUGA scan results are available and normal.
BleomycinPulmonary FunctionEnsure baseline pulmonary function tests (PFTs) and chest X-ray are reviewed.
Anatomy, Physiology & Pharmacology Points
  • Pathophysiology of Neuropathy: Chemotherapy-induced peripheral neuropathy (CIPN) is often due to damage to the axons or myelin sheath of sensory and motor nerves. Paclitaxel disrupts microtubule function, which is essential for nerve cell structure and transport.
  • Pharmacology: Carboplatin dosing is uniquely calculated using the Calvert formula, which incorporates the patient's glomerular filtration rate (GFR) and target area under the curve (AUC). This highlights why renal function is critical.
  • Lab Values: The provided labs show mild anemia (Hgb 10.2 g/dL, normal ~12-16 g/dL) but adequate WBC and platelets for treatment initiation (typically requires ANC >1,500/mm³ and platelets >100,000/mm³).
Memory Tips
  • Acronym: P.R.I.O.R. to Chemo
    Pre-medicate (steroids, antiemetics)
    Renal/Cardiac/Pulmonary baselines (drug-specific)
    Infusion rate & reaction monitoring
    Oncology emergency awareness (e.g., TLS, Sepsis)
    Rights of medication administration (double-check!)
  • For Paclitaxel, think: "Pins and needles come first" – assess neuro first.
High-Frequency NCLEX Topics NCLEX frequently tests priority-setting and assessment before intervention. Oncology questions often focus on:
1. Managing side effects (myelosuppression/infection, nausea, mucositis).
2. Patient education for self-care at home.
3. Safety and monitoring for specific drug toxicities (like this question).
4. Psychosocial support and therapeutic communication. Watch Out for Question Variations!
  • Instead of asking for the priority before chemo, the question could ask: "Which finding during paclitaxel infusion requires immediate intervention?" (Answer: Signs of a hypersensitivity reaction – dyspnea, chest tightness, hypotension).
  • Or: "The patient reports numbness in their fingertips after two cycles. What is the nurse's best action?" (Answer: Document the finding, report it to the oncologist, and perform a focused neurological assessment. This may lead to a dose reduction).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the oncology nurse preparing Ms. Johnson for her first cycle of carboplatin/paclitaxel. She is in her hospital bed post-op, anxious, and her IV is patent. The chemotherapy orders have been verified by the pharmacy. Nursing Intervention Strategy: 1. Assessment: Perform a systematic neurological exam. Use a monofilament to test sensation on the soles of the feet. Ask: "Do you have any tingling, numbness, or pain in your hands or feet? Can you walk to the bathroom without difficulty? Can you button your gown easily?" Test deep tendon reflexes (patellar, Achilles) and observe her gait if ambulatory. Document findings clearly in the chart. 2. Planning & Implementation: After establishing the baseline, proceed with other pre-chemo steps in order of urgency: * Verify recent lab results (CBC, CMP) are within acceptable limits for treatment. * Administer prescribed premedications (e.g., dexamethasone, diphenhydramine, H2 blocker) to prevent paclitaxel hypersensitivity. * Set up the infusion pump with the correct rate (paclitaxel is often infused over 3 hours; carboplatin over 30-60 mins). Never bolus chemotherapy. * Provide education about side effects, emphasizing which ones to report immediately (fever, shortness of breath, severe numbness/pain) versus those to manage at home. 3. Evaluation & Monitoring: Stay with the patient during the first 15 minutes of the paclitaxel infusion (highest risk for hypersensitivity reaction). Monitor vital signs frequently. After the infusion, reinforce teaching and schedule follow-up. Patient Safety and Precautions: * Chemotherapy Safe Handling: Always wear personal protective equipment (PPE) – gloves and gown – when handling or administering chemotherapeutic agents. * Extravasation: Monitor the IV site closely for signs of infiltration (swelling, pain, redness). Paclitaxel is a vesicant (can cause severe tissue damage). * Renal Protection: Encourage hydration before and after carboplatin to promote excretion and reduce nephrotoxicity. Nursing Procedure & Medication Flow Pre-Chemotherapy Checklist: 1. Patient Identification (Two identifiers) & Consent verified. 2. Baseline Assessments Complete (Neuro, Cardiac, Pulmonary, Renal as per drugs). 3. Recent Lab Values Reviewed and Approved. 4. IV Access Assessed (Patent, no signs of infiltration). 5. Premedications Administered (Allow time to take effect, e.g., 30-60 mins for steroids). 6. Chemotherapy Drugs Verified (Right patient, drug, dose, route, time, rate). 7. Emergency Equipment & Medications Available (For hypersensitivity/anaphylaxis). 8. Patient Education Provided and Understanding Confirmed. A Word from Your Senior Nurse "In oncology nursing, we walk a delicate line between fighting the cancer and protecting the patient from the treatment's effects. That baseline neuro check isn't just a box to tick. It's our promise to Ms. Johnson that we will watch over her nervous system as closely as we attack her cancer. When you see 'priority' on the NCLEX, always ask yourself: 'What action prevents the most harm or gathers the most essential information to guide safe care?' That mindset will lead you to the right answer. You've got this!"
