Questions And Well Graded Solutions
1. What is a common visual symptom associated with Multiple Sclerosis?
Retinal detachment
Optic neuritis
Cataracts
Glaucoma
2. If a 10-year-old child presents with symptoms such as headaches and
balance issues, which diagnostic approach would be most appropriate to
investigate a suspected pilocytic astrocytoma?
X-ray of the skull
CT scan of the abdomen
MRI of the brain
Blood tests for genetic markers
3. In a patient with a history of hypertension presenting with an S4 heart sound,
what would be the most appropriate next step in management?
Initiate anticoagulation therapy
Refer for cardiac surgery
Schedule for echocardiogram
Assess and manage blood pressure
4. Describe the genetic mechanism that leads to Myotonic Muscular Dystrophy.
, Myotonic Muscular Dystrophy is caused by a deletion in the DMPK
gene, resulting in loss of function.
Myotonic Muscular Dystrophy is caused by a point mutation in the
DMPK gene, affecting protein synthesis.
Myotonic Muscular Dystrophy is caused by a translocation involving
the DMPK gene, disrupting its expression.
Myotonic Muscular Dystrophy is caused by a CTG repeat expansion
in the DMPK gene, leading to abnormal protein function.
5. With damage to Wernicke's area, a patient would:
Have difficulty with speech comprehension
All answers are correct
Make up new words
Have increased output of speech and sounds
6. Describe the significance of oligoclonal bands in the diagnosis of multiple
sclerosis.
Oligoclonal bands indicate an immune response in the central
nervous system, which is characteristic of multiple sclerosis.
Oligoclonal bands are unrelated to neurological conditions.
Oligoclonal bands are a sign of normal immune function.
Oligoclonal bands suggest a bacterial infection in the cerebrospinal
fluid.
7. A rare benign neuroepithelial intraventricular WHO grade I lesion found in
the choroid plexus. It leads to increased cerebrospinal fluid production, thus
causing increased intracranial pressure and hydrocephalus.
, primary central nervous system lymphoma
neuroblastoma
choroid plexus papilloma
glioblastoma
8. What is the main pathological change observed in Multiple Sclerosis?
White matter demyelination
Neuronal apoptosis
Cerebral edema
Axonal regeneration
9. Describe the significance of ceruloplasmin levels in diagnosing Wilson's
disease.
Ceruloplasmin levels are unrelated to Wilson's disease and indicate
iron overload.
Decreased ceruloplasmin levels are a key indicator in diagnosing
Wilson's disease, as they reflect impaired copper metabolism.
Ceruloplasmin is a protein that has no diagnostic relevance in Wilson's
disease.
High ceruloplasmin levels are indicative of Wilson's disease and
suggest copper deficiency.
10. Describe how Type II Hypersensitivity Reactions can lead to tissue damage
in the body.
Type II Hypersensitivity Reactions involve the activation of T-cells that
attack foreign pathogens.
, Type II Hypersensitivity Reactions are characterized by the formation
of immune complexes that deposit in tissues.
Type II Hypersensitivity Reactions result in the release of histamines
that cause inflammation.
In Type II Hypersensitivity Reactions, antibodies bind to the body's
own cells, leading to their destruction and tissue damage.
11. A 9-year-old girl has early morning headaches, nausea, and trouble
balancing. An MRI of the brain is shown. What is the most likely diagnosis?
Diffuse brainstem glioma
Acoustic schwannoma
Ependymoma
Craniopharyngioma
Pilocytic astrocytoma
Oligodendroglioma
Medulloblastoma
12. Describe the relationship between erythema nodosum and sarcoidosis.
Erythema nodosum is a benign skin condition with no implications.
Erythema nodosum is a symptom of a viral infection.
Erythema nodosum is unrelated to any systemic condition.
Erythema nodosum is a skin condition that often indicates the
presence of sarcoidosis.
13. If a patient with multiple sclerosis experiences bowel incontinence, what
underlying mechanism might be causing this symptom?
