Study Notes
Objectives of Adult Nursing II
- Discuss conditions related to the nervous system, including altered consciousness, intracranial pressure, head injury, meningitis, encephalitis, brain abscess, stroke/CVA, and seizure disorders.
Increased Intracranial Pressure (ICP)
- The cranial vault consists of brain tissue (80%, approximately 1,400 g), blood (10%, about 75 mL), and cerebrospinal fluid (CSF) (10%, about 75 mL).
- Normal ICP ranges from 10 to 15 mmHg; values above 15 mmHg indicate abnormal levels.
- ICP is critical as increased pressure can lead to severe complications and potential life threats.
Monro-Kellie Hypothesis
- Suggests that within the rigid skull, an increase in any one intracranial component leads to compensatory decreases in others to maintain equilibrium.
- Compensation mechanisms include displacing CSF, enhancing absorption of CSF, or reducing cerebral blood volume.
Diagnostic Evaluations
- CT and MRI scans identify stroke-related damages like ischemic areas.
- Cerebral angiography assesses cerebrovascular insufficiency and structural abnormalities in blood vessels.
- Electroencephalogram (EEG) monitors electrical activities of the brain, especially post-injury.
Management of Ischemic Stroke
- Prioritize airway, breathing, circulation, and patients' neurological assessment.
- Fluid replacement and keeping blood pressure within target parameters (e.g., SBP ≥ 100 mmHg).
- Administer thrombolytic therapy and maintain normoglycemia and normothermia.
Management of Hemorrhagic Stroke
- Similar initial steps: secure airway, monitor neurological status, administer IV fluids.
- Blood pressure should be managed to prevent complications and promote perfusion.
Nursing Management Post-Craniectomy
- Maintain patient's airway, monitoring fluids and nutrition, preventing injury, and offering cognitive support.
- Regular assessments for neurological changes, including LOC, pupil reactions, and sensory/motor functions.
Complications Associated with Nervous System Conditions
- Potential for infections, increased ICP, hydrocephalus, and brain herniation.
- Risk of neurologic deficits, seizure disorders, and behavioral changes such as impulsivity or aggression.
Meningitis
- Inflammation of the protective membranes (meninges) surrounding the brain and spinal cord.
- Symptoms may present through signs in the CSF collected from the subarachnoid space.
Neurological Assessment
- Conduct health history focused on symptoms like pain, seizures, dizziness, motor weakness, and vision changes.
- Vital assessments include monitoring LOC, pupil reactions, vital signs, cranial nerves, reflexes, and sensory function.
Medical Management Considerations
- Recognize and treat hypoxia and acid-base imbalances promptly.
- Manage ICP via medications or surgical interventions such as burr holes or craniotomies as necessary.
Nursing Diagnoses
- Common diagnoses may involve ineffective airway clearance, risk for injury, fluid volume deficits, impaired skin integrity, and disturbed sensory perception.
Important Parameters Affecting ICP
- Cerebral Perfusion Pressure (CPP) calculation: CPP = Mean Arterial Pressure (MAP) - ICP; critical for assessing brain oxygenation and glucose supply.
- Any increases in Cerebral Blood Volume (CBV) relate directly to shifts in Cerebral Blood Flow (CBF) influenced by CPP dynamics.
