Oncology Nursing for the NCLEX-RN Exam

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

• !Confusing neutropenic precautions with reverse-isolation rules
• !Missing chemo-extravasation immediate response (stop infusion, aspirate, hot or cold compress per drug)
• !Wrong radiation-source safety distance / time / shielding
• !Mismatching tumor-lysis labs (K+ ↑, Phos ↑, Ca ↓, uric acid ↑)

Study tips

• 1Memorize the four oncologic emergencies and their first interventions.
• 2Drill neutropenic precautions for ANC < 500.
• 3Practice the time / distance / shielding rule for sealed and unsealed radiation sources.
• 4Know the chemo-extravasation immediate steps.

1. 1

   A patient with non-Hodgkin lymphoma develops K+ 7.0, Phos 7.5, Ca 7.5, uric acid 12 within 48h of starting chemotherapy. The priority nursing action is:

   • AAdminister allopurinol orally
   • BNotify the physician — these labs suggest tumor lysis syndromeCorrect
   • CIncrease IV fluids and continue monitoring
   • DPrepare for emergent dialysis
   Why this answer?

   These labs are the textbook tetrad of tumor lysis syndrome (K+↑, Phos↑, Ca↓, uric acid↑). It is an oncologic emergency requiring immediate physician notification, aggressive hydration, rasburicase, and possibly dialysis.
