If you only remember one thing: PNLE cancer questions often test “confirm with biopsy,” “manage chemo side effects,” “radiation safety,” and nursing process prioritization (ABCs first). This reviewer turns those into fast, testable rules—with PNLE-style examples and mini-rationales.

Quick Answer Cheat Sheet (Read This First)
Breast cancer diagnosis is confirmed by biopsy (e.g., fine-needle aspiration), not by mammogram or BSE.
Dysplasia = abnormal changes in cell size, shape, and organization (precancerous change).
Chemo dehydration red flag: dry oral mucosa + cracked lips.
Chemo stomatitis (oral mucositis): red, open sores on oral mucosa.
Radiation (any site) common adverse effect: fatigue.
Post-mastectomy complication: arm edema on operative side (lymphedema).
Internal radiation implant: usually bed rest; if dislodged, use forceps → lead-lined container.
Planning phase of nursing process: set patient-focused goals/outcomes and choose interventions.
Prioritization: Airway → Perfusion → other physiologic → psychosocial.
Oncology Must-Knows for PNLE (High-Yield Concepts)
1) “Screening” vs “Confirming” Cancer
PNLE items love this trap: tests that detect vs tests that confirm.
Screening/assessment tools: breast self-exam, mammography, PSA/DRE (for early detection).
Confirmation of cancer: tissue diagnosis via cytology/histopathology (biopsy).
Exam rule: If the question says “confirmed by,” your brain should answer: biopsy.
2) Cellular Changes: Dysplasia vs Others
Dysplasia: abnormal size/shape/organization of differentiated cells (precancerous).
Hyperplasia: increased number of normal cells in normal arrangement.
Metaplasia: one mature cell type replaced by another.
Anaplasia: completely undifferentiated malignant cells.
Memory hook: DYS = “Disorganized” cells.
3) The “CAUTION” Warning Signs of Cancer (Classic Review List)
Many PNLE review sets still use the CAUTION mnemonic. Know examples like nagging cough/hoarseness and persistent pain.
C: Change in bowel/bladder habits
A: A sore that does not heal
U: Unusual bleeding/discharge
T: Thickening or lump
I: Indigestion/difficulty swallowing
O: Obvious change in wart/mole
N: Nagging cough/hoarseness
Chemotherapy Nursing Care: Side Effects PNLE Loves
1) Fluid Volume Deficit (Dehydration)
Chemo can trigger vomiting/diarrhea/poor intake → dehydration. A classic sign is dry mucous membranes and cracked lips.
Watch for: dry mouth, poor skin turgor, dizziness, concentrated urine.
PNLE clue: normal potassium (e.g., 3.6 mEq/L) is not the answer when a better dehydration sign is present.
2) Stomatitis (Oral Mucositis)
Stomatitis presents as erythema, ulcerations, and painful open sores in the mouth.
Differentiate from oral candidiasis: white “cottage cheese” patches.
Basic nursing focus: oral care, pain control, nutrition support, infection prevention.
3) Thrombocytopenia Priorities
Low platelets = bleeding risk.
Top priority in plan: monitor platelet count and bleeding precautions.
Assessment: inspect for petechiae, bruising, bleeding gums.
Avoid: aspirin/NSAIDs unless ordered (platelet inhibition).
4) Antineoplastics Timing Questions
Alopecia often starts around 2–3 weeks after chemo begins.
Bone marrow suppression commonly becomes noticeable at about 7–14 days (typical nadir window in many regimens).
5) Tamoxifen: What to Report ASAP
Teach clients on tamoxifen to report vision changes immediately (potential ocular effects). Also remember tamoxifen has thromboembolic risk—even if not always listed in options.
Radiation Therapy: Systemic vs Local Effects + Safety
1) Radiation Adverse Effect at Any Site
Fatigue is the common systemic effect across treatment sites.
Hair loss is usually localized to the irradiated field.
Stomatitis is more common with head/neck irradiation.
2) Internal Radiation Implant (Brachytherapy) Safety
Two classic PNLE points:
Activity order: typically bed rest to prevent displacement.
If implant is found in linens: use long-handled forceps and place in a lead-lined container first (secure the source; minimize time/distance exposure).
Post-Op and Diagnostic Teaching: Rapid PNLE Review
Mastectomy: What Finding Signals a Complication?
Arm edema on operative side = possible lymphedema (key complication).
Expected/less alarming: incisional pain, early sanguineous JP drainage, some decreased sensation near incision.
Laryngectomy: Stoma Care
Air bypasses the upper airway → less humidification. Teach: keep the stoma moist to prevent thick secretions/crusting.
Pelvic Ultrasound for Ovarian Tumor Workup
For a transabdominal pelvic ultrasound, instruct client to drink water and avoid voiding to keep the bladder full for better visualization.
Men’s and Women’s Cancer Screening: What PNLE Usually Tests
Prostate Cancer Early Identification
Common screening includes PSA + digital rectal exam (DRE). (Always follow local and current guidelines in practice; PNLE questions usually test the classic pairing.)
Testicular Self-Exam (TSE) Basics
Best timing: after a warm shower (scrotum relaxed).
Frequency: commonly taught as monthly.
Teaching pearl: testicular cancer is highly curable if detected early.
Breast Self-Exam Timing (Premenopausal)
Best time: immediately after menstruation when breasts are least tender/swollen.
Cervical Cancer Risk Factor
Persistent high-risk HPV infection is the major risk factor.
Nursing Process (PNLE + NCLEX-Style): Planning & Prioritization
After Nursing Diagnoses, What’s Next?
Once you’ve identified nursing diagnoses, the next step is planning: create the care plan with goals/outcomes and interventions.
What Happens in the Planning Phase?
Set patient-focused objectives and anticipated outcomes
Choose appropriate interventions
Prioritize based on severity and immediate threats
How to Write a Measurable Outcome
Strong PNLE/NCLEX outcomes are specific and measurable.
Weak: “Pain will be reduced.”
Strong: “Client will report pain < 4/10 within 1 hour of intervention.”
Prioritization by ABCs: Sample Ordering
If you see options like:
Constipation
Expected grieving
Inadequate airway clearance
Insufficient tissue perfusion
Priority is: Airway (3) → Perfusion (4) → Constipation (1) → Grieving (2).
What To Do Now (To Actually Improve Your Score)
Drill 20 items/day on oncology + nursing process until the patterns feel automatic.
Create a one-page sheet of “PNLE traps” from this post: biopsy confirms, fatigue = radiation, petechiae = thrombocytopenia, ABCs first.
Practice writing outcomes using numbers (pain scale, vital signs, urine output, temperature).
