Flashcards covering key concepts related to Neurologic Infections, Autoimmune Disorders, and Neuropathies, designed to assist in exam preparation.
What is meningitis?
Meningitis is the inflammation of the meninges, the protective layers of the brain and spinal cord.
What is the classic triad of meningitis symptoms?
Fever, headache, and stiff neck.
What tests are important in diagnosing meningitis?
Brudzinski's and Kernig's tests.
How can meningitis be prevented?
Vaccines and prophylaxis.
What are early signs of increasing intracranial pressure (ICP)?
Signs of increased ICP include vomiting, confusion, and lethargy.
What are the two main types of meningitis?
Septic (bacterial) and aseptic (viral or non-bacterial).
What are common causes of septic meningitis?
Streptococcus pneumoniae and Neisseria meningitidis.
Which type of meningitis is more common during summer and fall?
Aseptic (viral) meningitis.
Who are at-risk populations for meningitis?
Unvaccinated students, military personnel, smokers, and those with URI.
What can lead to brain abscess formation?
Infection, often following otitis media or rhinosinusitis.
What is the common presentation of a brain abscess?
Headache, fever, mental changes, and seizures.
What imaging is preferred for detecting a brain abscess?
MRI provides better resolution for detecting lesions compared to CT.
What is the main cause of herpes simplex encephalitis (HSE)?
Herpes Simplex Virus Type 1 (HSV-1).
What is the gold standard diagnostic test for HSE?
PCR test to detect HSV-1 DNA in cerebrospinal fluid (CSF).
What is the first-line treatment for herpes simplex encephalitis?
Acyclovir IV.
What is Guillain-Barré Syndrome (GBS)?
A rare autoimmune disorder where the immune system attacks the myelin sheath of peripheral nerves.
What is a common infectious trigger for GBS?
Campylobacter jejuni.
How does GBS commonly present?
Symmetric muscle weakness that typically starts in the legs and ascends.
What is the first-line treatment for GBS?
Intravenous immunoglobulin (IVIG) and plasmapheresis.
What are key symptoms of trigeminal neuralgia?
Sudden, severe facial pain triggered by touch or everyday activities.
What is Bell's Palsy?
A sudden, temporary weakness or paralysis of the facial muscles on one side of the face.
What is the main treatment for Bell’s Palsy?
Corticosteroids like prednisone.
What are common symptoms of multiple sclerosis (MS)?
Numbness, weakness, visual disturbances, and cognitive impairment.
What diagnostic test is used to identify MS lesions?
MRI showing multiple plaques in the central nervous system.
What are common types of peripheral neuropathy?
Diabetic neuropathy and mononeuropathy.
What symptoms are associated with peripheral neuropathy?
Numbness, tingling, muscle weakness, and pain.
What is the immediate management strategy for increased ICP?
Neuro monitoring and reduction of fever/metabolic demand.
What are signs of increased ICP to monitor for in patients?
Decreased level of consciousness, pupil changes, and abnormal vital signs.
What is the purpose of a lumbar puncture in meningitis diagnosis?
To analyze cerebrospinal fluid (CSF) to confirm the type of meningitis.
How can encephalitis be differentiated from meningitis?
Encephalitis primarily involves brain tissue inflammation, while meningitis involves the protective membranes.
What is the major risk factor for developing multiple sclerosis?
Female gender and age between 20-40.
What are some environmental risk factors for multiple sclerosis?
Cold climates, low vitamin D levels, and high salt diet.
How does the immune response in MS cause symptoms?
Immune attack on myelin leads to inflammation and demyelination, impairing nerve signal transmission.
What distinguishes primary progressive MS from relapsing-remitting MS?
Primary progressive MS has a steady decline from the start without recovery periods.
What mnemonic can be used to remember MS symptoms?
FATIGUE: Fatigue, Ataxia, Tingling, Impaired vision, GI/GU disturbances, Unsteady gait, Emotional changes.
What are common treatments for peripheral neuropathy?
Managing underlying conditions, fall prevention, and symptomatic relief.
What are some important nursing interventions for patients with meningitis?
Infection control, monitoring vital signs, neuro assessments, and managing fever.
How can IVIG and plasmapheresis help in GBS?
Both reduce autoantibodies leading to quicker recovery and less time on a ventilator.
What does a positive Brudzinski's sign indicate?
It is a classic sign of meningeal irritation and possible meningitis.
What is the significance of diagnosing with PCR in encephalitis?
It detects specific viral DNA in the CSF, aiding in targeted treatment.
What does the presence of oligoclonal bands in CSF indicate in MS?
It indicates immune activity and is a part of its diagnostic criteria.
What can trigger a relapsing-remitting episode in MS patients?
Stress, infections, and significant physical exertion.
What are the complications to be aware of in untreated severe cases of meningitis?
Brain damage, hearing loss, and death.
What is the most common cause of pain in trigeminal neuralgia?
Demyelination of the trigeminal nerve, leading to hyperexcitability.
What are potential long-term outcomes for patients with cerebral abscess?
Severe cases can lead to lasting neurological deficits or death.
What is the role of corticosteroids in the management of brain swelling?
They help to reduce inflammation and manage symptoms of cerebral edema.
How do you manage the risk of aspiration in patients with facial paralysis?
Through careful monitoring during meals and upright positioning during feeding.
What lifestyle modifications can help manage MS symptoms?
Adequate rest, stress management, and avoidance of heat.
What diagnostic tests are often needed when considering GBS?
Lumbar puncture for CSF analysis and electrophysiological studies.
What common symptom management strategies are employed for peripheral neuropathy?
Pain management, maintaining skin integrity, and preventing falls.
What role does vaccination play in preventing bacterial meningitis?
It provides immunity against common pathogens like meningococcus and pneumococcus.
What are some non-pharmacological interventions for patients with severe MS fatigue?
Physical therapy, cognitive behavioral therapy, and implementing rest periods.
What is the primary goal of treatment in multiple sclerosis?
To delay disease progression and manage symptoms.
What role do family members play in the support of patients with neurological conditions?
Emotional and practical support, including education about the condition.
What immediate intervention may be necessary if a patient goes into shock?
Prompt fluid resuscitation and monitoring of vital signs.
How does the clinical presentation of encephalitis often differ from meningitis?
Encephalitis often includes more pronounced changes in behavior and cognitive function.
What is a significant distinguishing factor in the diagnosis of prion diseases such as CJD?
They are characterized by rapidly progressive dementia without inflammation.
What are common treatments for trigeminal neuralgia when medications fail?
Surgical interventions like microvascular decompression.
What are due diligence measures that nurses should take for patients post-brain surgery?
Monitor neurological status and prevent infection.
What is the importance of early recognition and treatment in the case of meningitis?
It significantly improves patient outcomes and reduces the risk of complications.
What medications are commonly used to control seizures in patients with neurological infections?
Anticonvulsants are used to manage seizure activity.
What symptom is most commonly associated with increased intracranial pressure (ICP)?
Headache that may worsen in intensity.
What are common interventions for managing cognitive symptoms in MS?
Cognitive rehabilitation and mental health support.
What are the signs of autonomic dysfunction in GBS?
Tachycardia, bradycardia, hypertension, or hypotension.
What nursing education should be provided to patients with Bell’s Palsy?
Information on eye care and the importance of maintaining facial muscle function.
