📚 Brain Tumor — 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.
A brain tumor is an abnormal growth of cells within the skull that may be primary (originating in brain tissue) or metastatic (spread from another site such as lung or breast). Because the skull is a fixed space, an enlarging tumor raises intracranial pressure and compresses surrounding tissue, producing symptoms based on its location. Common features include a new or worsening headache (often worse in the morning), seizures, vomiting, and progressive focal neurologic deficits. Treatment may combine surgery, radiation, and chemotherapy.
🔑
Key points
Understand these first
Symptoms result from increased intracranial pressure and local compression: headache classically worse in the morning or with coughing/straining, projectile vomiting, and papilledema.
New-onset seizures, progressive focal deficits, personality or cognitive changes, and visual disturbances are common presenting signs.
Specific deficits map to tumor location (e.g., frontal lobe — personality changes; cerebellar — balance/coordination; occipital — vision).
Diagnosis is confirmed with MRI with contrast; corticosteroids (dexamethasone) reduce peritumoral edema and ICP.
Management may include surgical resection, radiation, and chemotherapy, with seizure prophylaxis as indicated.
✅
Nursing priorities
What to do, in order
Monitor neurologic status frequently and assess for rising intracranial pressure.
Position with head of bed elevated about 30 degrees, head midline, and avoid activities that increase ICP (straining, coughing).
Maintain seizure precautions and administer anticonvulsants and corticosteroids as ordered.
Manage pain and nausea, and monitor for and address neurologic deficits affecting safety (vision, balance, swallowing).
Provide emotional support and education regarding diagnosis, treatment options, and prognosis.
🚩
Red flags — report now
Escalate immediately
Decreasing level of consciousness, unequal/fixed pupils, widening pulse pressure with bradycardia (Cushing triad), or projectile vomiting indicating dangerously increased ICP and possible herniation — emergency.
New or prolonged seizure activity (status epilepticus) or sudden severe worsening of deficits.
🧪
Labs & values
Numbers to know
Monitor blood glucose while on corticosteroids (dexamethasone can cause hyperglycemia; normal fasting 70 to 99 mg/dL)
Serum sodium 135 to 145 mEq/L — watch for SIADH or diabetes insipidus with tumors near the pituitary/hypothalamus
🗣️
Patient teaching
What patients must know
Report worsening headache, new vomiting, vision changes, weakness, or seizures promptly.
Take corticosteroids and anticonvulsants exactly as prescribed and do not stop steroids abruptly.
Avoid activities that raise intracranial pressure such as straining and heavy lifting.
Understand the planned treatment (surgery, radiation, chemotherapy) and expected side effects.
Use safety measures at home for any balance, vision, or weakness deficits and arrange support as needed.
❓ Brain Tumor: NCLEX FAQs
What are the priority nursing interventions for Brain Tumor?
Monitor neurologic status frequently and assess for rising intracranial pressure. Position with head of bed elevated about 30 degrees, head midline, and avoid activities that increase ICP (straining, coughing). Maintain seizure precautions and administer anticonvulsants and corticosteroids as ordered. Manage pain and nausea, and monitor for and address neurologic deficits affecting safety (vision, balance, swallowing).
What are the warning signs of Brain Tumor a nurse must report?
Decreasing level of consciousness, unequal/fixed pupils, widening pulse pressure with bradycardia (Cushing triad), or projectile vomiting indicating dangerously increased ICP and possible herniation — emergency. New or prolonged seizure activity (status epilepticus) or sudden severe worsening of deficits.
