BSN 445 Week 11 Sherpath 2026/2027 – 60+ Questions & Answers | Neuro Assessment, Stroke, ICP, GCS & Craniotomy

This BSN 445 Week 11 Sherpath 2026/2027 exam preparation resource contains 60+ questions with answers across 32 pages, providing an in-depth review of neurologic assessment, level of consciousness, Glasgow Coma Scale (GCS), FOUR Score, cranial and pupillary assessment, intracranial pressure (ICP), cerebral perfusion, neurodiagnostic testing, stroke, Guillain-Barré syndrome, craniotomy, and brain herniation. The opening section develops systematic neurologic assessment skills by reviewing symptom onset and progression, changes in neurologic status, deep tendon and superficial reflexes, pupil size and reactivity, eye movements, the doll’s-eye response, respiratory patterns associated with neurologic injury, and differences between assessment of conscious and unconscious patients. A major portion concentrates on intracranial pressure and neurologic deterioration. Students review normal ICP, Cushing triad, stages of intracranial hypertension, autonomic cardiovascular manifestations, altered respiratory patterns, and signs associated with brain herniation. Questions connect changes such as lethargy, abnormal pupillary responses, widening pulse pressure, bradycardia, dysrhythmias, and respiratory abnormalities with worsening cerebral function. The resource also emphasizes rapid recognition of changes from baseline because deterioration in neurologic status may provide an early indication of worsening intracranial pathology. The neurodiagnostic and neuromonitoring sections cover cervical spine radiography, angiography, CT, MRI, perfusion-weighted MRI, myelography, electroencephalography, evoked potentials, cerebrospinal fluid analysis, transcranial Doppler, transcranial color-coded duplex sonography, laser Doppler flowmetry, LICOX brain-tissue oxygen monitoring, cerebral microdialysis, and continuous EEG. Students review factors affecting cerebral blood flow, including carbon dioxide, mean arterial pressure, and ICP, while connecting monitoring technologies with cerebral perfusion, brain oxygenation, metabolism, capillary blood flow, and seizure or neurologic-injury detection. Another substantial section addresses stroke, subarachnoid hemorrhage, and cerebral aneurysms. Risk-reduction concepts include hypertension control, smoking cessation, healthy diet, and glucose management. Students distinguish ischemic and hemorrhagic events and review arteriovenous malformations, the classic severe headache associated with subarachnoid hemorrhage, the National Institutes of Health Stroke Scale (NIHSS), limb ataxia testing, hemiparesis, homonymous hemianopsia, vasospasm, and prevention of thromboembolic complications. The document also examines thrombolytic therapy and the importance of blood-pressure management and close observation for intracranial hemorrhage following treatment. The resource extends into coma and Guillain-Barré syndrome (GBS). Students review metabolic causes of altered consciousness, relevant glucose, calcium and sodium abnormalities, breathing patterns associated with medullary injury, and pharmacologic considerations in unexplained loss of consciousness. GBS content emphasizes the association with a preceding respiratory infection, progressive neurologic manifestations, rehabilitation education, and especially respiratory monitoring. Frequent assessment of respiratory function is highlighted because progressive neuromuscular weakness can compromise ventilation. The neurosurgical section covers craniotomy, cranioplasty, transsphenoidal surgery, postoperative neurological assessment, cerebrospinal fluid leakage, cerebral edema, and complications such as syndrome of inappropriate antidiuretic hormone secretion. Preoperative laboratory preparation includes a complete blood count, renal function assessment, and type and crossmatch. Postoperative scenarios address clear nasal drainage following transsphenoidal surgery, neurological and infection surveillance, head-of-bed positioning, cerebral tissue swelling, and findings requiring rapid communication with the healthcare provider. The final section integrates the Monro-Kellie doctrine, cerebral perfusion pressure (CPP), ICP monitoring, mannitol, and brain herniation. Students practice interpreting relationships among arterial blood pressure, MAP, ICP and CPP and review intraventricular catheters, subarachnoid screws, epidural transducers, and parenchymal monitoring. Questions also address CSF accumulation from choroid plexus tumors, aqueductal stenosis and obstructed arachnoid villi, early manifestations of central herniation, and nursing interventions that may exacerbate ICP. Mannitol is discussed in relation to reducing cerebral tissue volume and controlling intracranial hypertension. For evidence-based reinforcement, these concepts correspond closely with AACN Essentials of Critical Care Nursing and Lewis’s Medical-Surgical Nursing: Assessment and Management of Clinical Problems. Stroke assessment and treatment should additionally be compared with current American Heart Association/American Stroke Association (AHA/ASA) guidelines, while severe traumatic brain injury, ICP and CPP management can be reinforced using current Brain Trauma Foundation recommendations. Students should verify thrombolytic eligibility, blood-pressure thresholds, ICP treatment targets, neurosurgical procedures, and other time-sensitive interventions against current clinical guidelines because practice standards may change. Relevant Students: This document is particularly relevant for BSN 445 students, Sherpath nursing students, BSN and RN students, critical-care and ICU nursing students, neuroscience nursing students, adult health and medical-surgical nursing students, and learners preparing for neurological critical-care examinations. It can also support HESI, ATI Adult Medical-Surgical, NCLEX-RN, and critical-care preparation involving neurologic assessment, stroke, GCS, ICP, CPP, brain herniation, cerebral aneurysm, subarachnoid hemorrhage, Guillain-Barré syndrome, craniotomy, and neurodiagnostic testing.
