📚 Lung Cancer — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Lung cancer is a malignant tumor arising in the lung tissue and is the leading cause of cancer death. It is broadly classified as small cell (SCLC, aggressive, strongly smoking-related) or non-small cell (NSCLC, most common). The leading risk factor by far is cigarette smoking. Symptoms often appear late, so prognosis is frequently poor at diagnosis.
🔑
Key points
Understand these first
Smoking is the leading risk factor; other risks include radon, asbestos, and secondhand smoke exposure.
Early disease is often asymptomatic; a persistent cough, hemoptysis, dyspnea, hoarseness, and chest pain are common signs.
Small cell lung cancer is aggressive, metastasizes early, and is associated with paraneoplastic syndromes (e.g., SIADH, Cushing's).
It is a common cause of superior vena cava syndrome and malignant pleural effusion.
Diagnosis uses chest imaging and biopsy/bronchoscopy; treatment includes surgery, chemotherapy, radiation, and targeted/immunotherapy.
Low-dose CT screening is recommended for high-risk current/former heavy smokers.
✅
Nursing priorities
What to do, in order
Maintain a patent airway and optimize oxygenation; position upright and provide oxygen as prescribed.
Assess respiratory status, breath sounds, and effectiveness of breathing; monitor for worsening dyspnea.
Manage pain and energy conservation; cluster care to reduce fatigue and oxygen demand.
Support effective coughing and secretion clearance; monitor sputum for hemoptysis.
Provide emotional support, smoking cessation resources, and end-of-life/palliative discussions as appropriate.
🚩
Red flags — report now
Escalate immediately
Sudden severe dyspnea, increasing hemoptysis, or signs of airway obstruction require immediate intervention.
Acute chest pain with shortness of breath may indicate pleural effusion, pneumothorax, or pulmonary embolism.
🧪
Labs & values
Numbers to know
Sputum cytology: may show malignant cells
Chest CT/biopsy: diagnostic
Serum sodium: may be low with SIADH (normal 135-145 mEq/L)
Pulmonary function tests: assess surgical candidacy
🗣️
Patient teaching
What patients must know
Stop smoking and avoid secondhand smoke; provide cessation resources and support.
Report persistent cough, blood in sputum, worsening shortness of breath, hoarseness, or unexplained weight loss.
Conserve energy by pacing activities and resting between tasks.
Use prescribed oxygen safely (no smoking or open flames near oxygen).
High-risk heavy smokers should discuss low-dose CT lung cancer screening with their provider.
❓ Lung Cancer: NCLEX FAQs
What are the priority nursing interventions for Lung Cancer?
Maintain a patent airway and optimize oxygenation; position upright and provide oxygen as prescribed. Assess respiratory status, breath sounds, and effectiveness of breathing; monitor for worsening dyspnea. Manage pain and energy conservation; cluster care to reduce fatigue and oxygen demand. Support effective coughing and secretion clearance; monitor sputum for hemoptysis.
What are the warning signs of Lung Cancer a nurse must report?
Sudden severe dyspnea, increasing hemoptysis, or signs of airway obstruction require immediate intervention. Facial/neck swelling, distended neck veins (superior vena cava syndrome) need prompt reporting. Acute chest pain with shortness of breath may indicate pleural effusion, pneumothorax, or pulmonary embolism.
What do I need to know about Lung Cancer for the NCLEX?
Smoking is the leading risk factor; other risks include radon, asbestos, and secondhand smoke exposure. Early disease is often asymptomatic; a persistent cough, hemoptysis, dyspnea, hoarseness, and chest pain are common signs. Small cell lung cancer is aggressive, metastasizes early, and is associated with paraneoplastic syndromes (e.g., SIADH, Cushing's).

What patient teaching is important for Lung Cancer?
Stop smoking and avoid secondhand smoke; provide cessation resources and support. Report persistent cough, blood in sputum, worsening shortness of breath, hoarseness, or unexplained weight loss. Conserve energy by pacing activities and resting between tasks. Use prescribed oxygen safely (no smoking or open flames near oxygen).
