XIII. Comprehensive Pathophysiology PREDISPOSING FACTORS PRECIPITATING FACTORS Cigarette Smoker: 7.5 pack years Heavy alcohol drinker for 30 years Diet: High fat foods Hypertension Age: Advanced age Gender: Female Family History: Stroke Location of the Aneurysm Rupture of left MCA aneurysm Blood spews out of the damaged blood vessel. DIAGNOSTIC: CT Scan SURGERY: Emergency Right Ventriculostomy Tube Increased ICP, direct pressure on nearby tissues & blood vessels, and vasospasm Reduces blood flow to the brain causes deprivation of oxygenrich blood other tissues & cells DIAGNOSTIC: CXR Dyspnea, internal & subcostal retractions noted; connected to mechanical ventilator via ET tube with 80% FiO2 - Episodes of tachypnea: RR ranging from 20-29cpm - White secretions noted upon suctioning. - Crackle noted on the right lower lung upon auscultation ---INEFFECTIVE AIRWAY CLEARANCE-- DIAGNOSTIC: CBC RESULT: Leukocytes: high (15.88) x 10^9/L Neutrophils: high (0.92) Lymphocytes: high (0.6) LEGENDS: Risk Factors------------------Pathophysiology------------Surgery----------------------Etiology & Final Diagnosis--Manifestation----------------Diagnostic Test--------------Nursing Diagnosis------------ Cerebral perfusion Sudden increase of blood pressure Altered level of consciousness Creating a pool of blood in the subarachnoid space. (SUBARACHNOID HEMORRHAGE) - Tachypneic - NGT feeding noted - Ventriculostomy tube with light red drainage - Partially compensated respiratory alkalosis DIAGNOSTIC: ABG Analysis RESULT pH: elevated (7.54) Bicarbonate: low (14.50 mmol/L) ---ACID BASE IMBALANCE--- Irritation of the meninges Inflammation and scarring of surrounding tissues. Obstruction of CSF outflow. Hydrocephalus Increased intracranial pressure Altered level of consciousness ---ALTERED BREATHING PATTERN--- - Febrile; skin warm to touch. - Diaphoretic - Temperature ranging from 37.6 – 38.7 oC ---ELEVATED BODY TEMPERATURE--- - Skin turgor: > 2sec - With intact NGT and OF feeding - GCS: 5/15 DIAGNOSTIC: Blood Chemistry RESULT: Sodium: high (146.78 mmol/L) Potassium: low (2.86 mmol/L) Glucose: high (117.66 mg/dL) ---RISK FOR LESS THAN NUTRITIONAL IMBALANCE---
