Patho EXAM 3 SG - Suriaga Original Questions Flashcards
What is Muscular Dystrophy (MD)?
A group of inherited genetic disorders causing progressive weakness and loss of muscle mass due to defects in muscle proteins
Duchenne Muscular Dystrophy (DMD) is the most common and severe form, caused by a mutation in the dystrophin gene.
What are the signs and symptoms of Muscular Dystrophy?
Progressive muscle weakness, difficulty walking, frequent falls, calf muscle hypertrophy, respiratory difficulties, heart problems
Symptoms often start in the legs.
What nursing interventions are important for Muscular Dystrophy?
Monitor respiratory function, promote mobility, prevent contractures, manage complications, provide emotional support, educate about assistive devices
What is fasciculation?
Involuntary, fine muscle twitches due to spontaneous depolarization of a lower motor neuron or its muscle fibers
What are the levels of spinal cord injury?
Cervical (C1-C8), Thoracic (T1-T12), Lumbar/Sacral (L1-S5)
Each level affects different bodily functions, such as mobility and bowel/bladder control.
What are the nursing interventions for spinal cord injury?
Immediate immobilization, maintain airway and breathing, prevent complications like pressure ulcers and DVT
What neurotransmitter is affected in Myasthenia Gravis?
Acetylcholine at the neuromuscular junction
What are the signs and symptoms of Myasthenia Gravis?
Muscle weakness that worsens with activity, ptosis, diplopia, dysphagia, difficulty breathing in severe cases
What diagnostic tests are used for Myasthenia Gravis?
Tensilon test, acetylcholine receptor antibody test, electromyography (EMG)
What is a myasthenic crisis?
Exacerbation of muscle weakness due to insufficient medication or stressors, requiring respiratory support
What is a cholinergic crisis?
Overmedication with anticholinesterase drugs causing excessive acetylcholine, leading to muscle weakness and respiratory failure
What neurotransmitter is affected in Parkinson’s Disease?
Dopamine
What are the clinical signs and symptoms of Parkinson’s Disease?
Resting tremor, bradykinesia, muscle rigidity, postural instability, shuffling gait, mask-like facial expression
What are the nursing interventions for Parkinson’s Disease?
Administer dopaminergic medications, promote physical therapy, prevent falls, assist with ADLs, monitor for medication side effects
What is demyelination in Multiple Sclerosis?
Immune-mediated destruction of the myelin sheath in the central nervous system
What are the risk factors for Multiple Sclerosis?
Genetic susceptibility, environmental factors, possibly viral infections
What is the treatment for Multiple Sclerosis?
Immunomodulatory drugs, corticosteroids for acute relapses, physical therapy, symptomatic management
What are the types of dementia?
Alzheimer’s Disease, Vascular Dementia, Lewy Body Dementia, Frontotemporal Dementia
