NURS 5315 Advanced Pathophysiology Exam 3 2026/2027 – 150+ Questions & Answers | Cardiovascular, Respiratory, Shock, TBI, ICP, Stroke & Seizures | UTA

This NURS 5315 Advanced Pathophysiology Exam 3 2026/2027 resource is an extensive 70-page exam study guide with 150+ questions and detailed answers designed around major cardiovascular, pulmonary and neurological pathophysiology concepts. The document provides explanation-based answers rather than simple answer keys, helping students review disease mechanisms, risk factors, clinical manifestations, physiologic compensation, complications and important diagnostic concepts. Major areas include valvular heart disease, atherosclerosis, congenital heart defects, heart failure, coronary artery disease, myocardial infarction, respiratory disorders, shock, traumatic brain injury, intracranial pressure, stroke and seizure disorders. The cardiovascular pathophysiology section begins with valvular disorders, including mitral stenosis, mitral regurgitation, aortic stenosis and aortic regurgitation. It connects structural valve abnormalities with changes in pressure, ventricular or atrial remodeling, pulmonary vascular congestion and characteristic manifestations. Atherosclerosis is explored through endothelial injury, inflammation, LDL accumulation, macrophage activity, foam-cell formation, fatty streaks, smooth-muscle proliferation, fibrous plaque formation and eventual ischemia or infarction. Congenital cardiovascular disease is addressed through left-to-right and right-to-left shunts, Eisenmenger syndrome, ventricular septal defect, atrial septal defect, patent ductus arteriosus and Tetralogy of Fallot. The questions emphasize changes in oxygen saturation, pulmonary hypertension, ventricular hypertrophy, cyanosis and characteristic murmurs, while also reviewing maternal and environmental risk factors associated with congenital heart abnormalities. The heart-failure material differentiates heart failure with reduced ejection fraction (HFrEF), heart failure with preserved ejection fraction (HFpEF), systolic dysfunction, diastolic dysfunction and right-sided heart failure. Students review changes in contractility, preload, stroke volume and cardiac output as well as ventricular remodeling, sympathetic activation and the renin-angiotensin-aldosterone system (RAAS). The guide also connects left-sided failure with pulmonary congestion and right-sided failure with jugular venous distention, hepatosplenomegaly and peripheral edema. A particularly detailed section examines coronary artery disease and acute coronary syndromes. It reviews CAD risk factors, stable and Prinzmetal angina, unstable angina, NSTEMI and STEMI, followed by the cellular pathophysiology of myocardial infarction. Students encounter concepts involving myocardial ischemia, ATP depletion, anaerobic metabolism, lactic-acid accumulation, catecholamine responses, troponins and reperfusion injury. Complications covered include ventricular fibrillation, cardiogenic shock, pulmonary edema, ventricular free-wall rupture, papillary-muscle rupture, ventricular-septal rupture, mural thrombus, ventricular aneurysm and post-infarction pericarditis. The respiratory pathophysiology portion distinguishes restrictive and obstructive lung disease and reviews acute respiratory failure, croup, spontaneous and tension pneumothorax, pulmonary edema and acute respiratory distress syndrome (ARDS). ARDS is organized into inflammatory, proliferative and fibrotic phases and further differentiated into direct pulmonary versus indirect extrapulmonary injury. Students also receive substantial review of asthma, COPD, alpha-1 antitrypsin deficiency, emphysema, chronic bronchitis, pneumonia, tuberculosis, lung cancer, pulmonary arterial hypertension and cor pulmonale. The document connects airway remodeling and IgE-mediated responses with asthma, loss of elastic recoil and air trapping with emphysema, mucus hypersecretion with chronic bronchitis, and pulmonary hypertension with progressive right-ventricular workload and right-sided heart failure. Another major component covers circulatory shock, beginning with impaired tissue perfusion, hypoxia, anaerobic metabolism and lactic-acid production. The resource distinguishes the nonprogressive, progressive and irreversible stages of shock and reviews hypovolemic, cardiogenic, septic, neurogenic and anaphylactic shock, emphasizing the different mechanisms involving reduced circulating volume, pump failure, widespread vasodilation and immune-mediated responses. The neurological section provides extensive coverage of traumatic brain injury (TBI), including Glasgow Coma Scale assessment, primary versus secondary and tertiary brain injury, focal and diffuse injury, coup-contrecoup injuries, contusions, concussions, penetrating trauma and basilar skull fractures. It further differentiates intracerebral, epidural, subdural and subarachnoid hemorrhage, including the lucid interval associated in the document with epidural hematoma and the thunderclap headache associated with subarachnoid hemorrhage. Post-concussive syndrome and chronic traumatic encephalopathy (CTE) are also reviewed. The intracranial pressure and cerebral perfusion section explains the inverse relationship between ICP and cerebral perfusion pressure (CPP) and follows the progression from cerebral compensation to hypoxia, decreased consciousness and brain herniation. High-yield concepts include Cushing's triad, decorticate and decerebrate posturing, Cheyne-Stokes respirations, uncal herniation, central herniation, transcalvarial herniation and cerebellar tonsillar herniation. Stroke content covers thrombotic, embolic, lacunar and hemorrhagic strokes, along with transient ischemic attacks and the Circle of Willis. The guide associates cerebral vascular territories with characteristic neurological deficits, including the anterior cerebral, middle cerebral, posterior cerebral, basilar and cerebellar arteries, and reviews aphasia/dysphasia and other neurological manifestations following vascular occlusion. The document further reviews focal and generalized seizures, seizure aura, simple and complex partial seizures, Jacksonian march, automatisms, tonic and clonic seizures, tonic-clonic seizures, status epilepticus and non-convulsive status epilepticus. It also introduces acute confusional states and meningitis, giving students an integrated review of neurological dysfunction and associated pathophysiologic mechanisms. Relevant Students: This study resource is particularly relevant to University of Texas at Arlington (UTA) NURS 5315 students, advanced pathophysiology students, graduate nursing students, MSN students, nurse practitioner students, FNP and AGACNP learners, advanced practice nursing students and students preparing for Exam 3. Its systems-based explanations also make it useful for students who need concentrated review of cardiovascular, pulmonary, shock and neurological pathophysiology before advanced nursing examinations.
