Chemotherapy PrecautionsNCLEX cheat sheet

Chemotherapy uses cytotoxic drugs that destroy rapidly dividing cells, harming both cancer cells and healthy fast-growing cells (bone marrow, GI lining, hair follicles).

Effects

  • myelosuppression: ↓WBC ↓RBC ↓plt
  • N/V, alopecia, mucositis
  • nadir 7-14 days = lowest counts

Report

  • fever (neutropenia) = emergency
  • EXTRAVASATION → stop infusion NOW
  • bleeding, SOB, infection signs

Safety

  • double-glove handling chemo
  • body fluids hazardous 48h
  • double-flush toilet, wear PPE

Do

  • antiemetics BEFORE chemo
  • soft toothbrush, oral care, small meals
Red flag to remember

Report extravasation signs immediately: pain, burning, swelling, or no blood return at the IV site.

Before you read

Test yourself first: 5 questions

Question 1 of 5

A nurse is preparing and administering chemotherapy. Which action indicates the nurse needs further teaching on safe handling of hazardous antineoplastic drugs?

What is chemotherapy precautions?

Precautions protect both the patient from toxic side effects and the nurse/family from hazardous drug exposure. It matters because chemo agents are hazardous, vesicants can cause severe tissue damage, and bone marrow suppression creates infection and bleeding risk.

Key points to remember

  • Bone marrow suppression causes neutropenia, thrombocytopenia, and anemia (the three big toxicities).
  • GI effects include nausea, vomiting, mucositis/stomatitis, and diarrhea.
  • Vesicant drugs cause severe tissue necrosis if they extravasate (leak from the vein).
  • Alopecia, fatigue, and altered taste are common and distressing but reversible.
  • Cytotoxic drugs are hazardous and present in the patient's body fluids for about 48 hours after a dose.
  • Tumor lysis syndrome can follow rapid cell kill, causing hyperkalemia, hyperphosphatemia, and hyperuricemia.

Nursing priorities

  1. Wear personal protective equipment (chemo gown, double gloves) when handling drugs, spills, or body fluids.
  2. Monitor the IV site continuously for vesicants; if extravasation occurs, stop the infusion immediately and follow the antidote protocol.
  3. Implement neutropenic and bleeding precautions based on blood counts.
  4. Administer antiemetics before chemotherapy and provide gentle oral care for mucositis.
  5. Ensure hydration and monitor labs for tumor lysis syndrome and organ toxicity.

Labs & values

Absolute neutrophil count and WBC (normal5,000-10,000/mm3) monitored, often decreased at nadir
Platelets (normal150,000-400,000/mm3) monitored for decrease
Potassium, phosphorus, and uric acid monitored for tumor lysis

Patient teaching

  • For about 48 hours after chemo, flush the toilet twice with the lid closed and wash hands well; handle body fluids carefully.
  • Avoid crowds and sick contacts, take temperature daily, and report fever or bleeding promptly.
  • Expect hair loss (it regrows), use a soft toothbrush for mouth soreness, and take antinausea medicine as prescribed.

Red flags: report now

  • Report extravasation signs immediately: pain, burning, swelling, or no blood return at the IV site.
  • Report a fever of 100.4 F (38 C) or higher in a neutropenic patient; it is a medical emergency.
  • Report signs of tumor lysis syndrome or anaphylaxis during infusion (wheezing, hypotension, urticaria).
