Oral cryotherapy (ice chips or cold water rinses) during and immediately after melphalan infusion reduces mucosal blood flow, limiting drug delivery to oral tissues and thereby decreasing the incidence and severity of mucositis. This low-cost, well-tolerated intervention has strong support in conditioning regimens that include short–half-life agents like melphalan. Chlorhexidine rinses (Option A) do not prevent chemotherapy-induced mucositis and may worsen irritation. Routine prophylactic antibiotics (Option C) are not indicated solely for mucositis prevention and contribute to antimicrobial resistance. Sucralfate (Option D) has not shown consistent benefit in prevention. APRNs should implement a comprehensive oral care protocol—baseline dental evaluation, soft-bristle brushing, saline/baking soda rinses, avoidance of irritants, pain management, and nutritional support—while educating patients on early symptom reporting. For severe cases, consider analgesic strategies (topical and systemic), parenteral nutrition if needed, and evaluation for palifermin in select transplant settings per institutional policy.

LDCT screening reduces lung cancer mortality in high-risk adults. Eligibility commonly includes age beginning at 50 and a ≥20 pack-year history who currently smoke or quit within the past 15 years. This patient qualifies. Screening is annual while criteria remain met and the individual is healthy enough to undergo curative therapy if a cancer is found. Chest X-ray and sputum cytology (Option A) have not shown mortality benefit. A single baseline CT (Option C) misses interval cancers; benefits accrue with repeated annual scans. Dismissing screening due to age <55 (Option D) reflects outdated thresholds. Shared decision-making should include benefits, false positives, incidental findings, radiation exposure, and the critical role of smoking cessation—the most effective cancer prevention strategy. The APRN coordinates referral to an accredited LDCT program, ensures standardized nodule management (Lung-RADS), addresses comorbidities that influence surgical candidacy, and provides cessation pharmacotherapy and counseling, documenting the plan and recall schedule in the EHR.

High-quality cancer care integrates clear communication about diagnosis, prognosis, treatment intent, and patient values from the outset—especially in cancers with limited curative potential like metastatic pancreatic adenocarcinoma. Early palliative care alongside disease-directed therapy improves symptom control, quality of life, care alignment with patient preferences, and may reduce aggressive, non-beneficial end-of-life interventions. The APRN facilitates a structured goals-of-care conversation covering understanding of illness, priorities (e.g., symptom relief, time at home), acceptable tradeoffs, and preferred decision-making supports. This does not diminish hope; it reframes hope toward achievable outcomes and ensures that treatment choices reflect what matters most to the patient. Deferring discussions (Option A) risks crisis-driven decisions. Withholding information unless prompted (Option C) undermines informed consent. Avoiding advance care planning (Option D) is contrary to patient-centered care. Documentation of preferences, advance directives, and surrogate decision makers should be completed and revisited as the disease course evolves.

Suspected malignant spinal cord compression (MSCC) is an oncologic emergency. Prompt initiation of high-dose corticosteroids (e.g., dexamethasone 10 mg IV bolus followed by 4–6 mg IV/PO every 6 hours) reduces vasogenic edema and may preserve neurologic function. Emergent MRI of the entire spine is essential to localize the lesion(s); plain radiographs are insensitive. Early multidisciplinary coordination with neurosurgery and radiation oncology determines definitive management—surgical decompression with stabilization offers the best chance of ambulation in selected patients (particularly with single-level disease, radiosensitive or radioresistant histologies, and acceptable performance status), while urgent external beam radiation therapy is preferred for nonoperative candidates or radiosensitive disease. Delay in imaging and treatment (Option A) risks irreversible deficits. Low-dose oral prednisone (Option C) is inadequate. Antibiotics (Option D) are not indicated unless there is evidence of infectious epidural abscess. Bladder catheterization, VTE prophylaxis, and analgesia are supportive priorities while definitive therapy proceeds.

Readiness reduces morbidity. A robust program includes standardized order sets for premedication and an on-chairside emergency kit (epinephrine IM/IV dosing, diphenhydramine, H2 blocker, methylprednisolone, albuterol, normal saline, oxygen, airway adjuncts). Protocols specify grading (mild/moderate/severe/anaphylaxis) and actions: immediate stop infusion, maintain IV access, rapid medication sequence, escalation to code team/ED if unstable, and criteria for rechallenge vs desensitization referral. Regular simulation drills improve role clarity and response time; equipment/med expiry checks ensure availability. Premedication (Option C) reduces but does not eliminate reactions. Delayed retrieval of epinephrine (Option A) wastes precious minutes. Automatically calling 911 (Option D) may delay immediate interventions and is unnecessary for mild/moderate cases when trained teams are present. The APRN oversees training, event documentation (including CTCAE grade), root-cause analysis, and communication with allergy/oncology for desensitization planning, improving patient safety and staff confidence.
