a) Involuntary muscle movements
b) Difficulty with motor planning to perform tasks
c) Loss of sensation
d) Difficulty recognizing objects
Answer: b) Difficulty with motor planning to perform tasks

How often does OSHA require leakage current testing?
a) Weekly
b) Monthly
c) Semiannually
d) Annually
Answer: c) Semiannually

healthcare settings.
Which type of seizure starts with the head and eyes turning to one side?
a) Generalized seizure
b) Adversive seizure
c) Absence seizure
d) Myoclonic seizure
Answer: b) Adversive seizure
,Rationale: Adversive seizures often involve the turning of the head and eyes as a clinical
feature.
What dysfunction is indicated by a unilateral Babinski sign?
a) Cerebellar dysfunction
b) Pyramidal tract dysfunction
c) Basal ganglia disorder
d) Optic nerve damage
Answer: b) Pyramidal tract dysfunction
Rationale: The Babinski sign is a clinical indicator of damage to the corticospinal (pyramidal)
tract.
What is a unilateral Babinski sign?
a) The loss of reflex in one foot
b) A test for involuntary muscle retraction when the foot is stroked
c) A condition where toes spread apart during walking
d) A sign of muscle atrophy
Answer: b) A test for involuntary muscle retraction when the foot is stroked
Rationale: The Babinski test involves stroking the sole to assess the reflex, indicating
neurological health.
What clinical sign is expected in a stroke involving the basilar artery?
a) Double vision (diplopia)
b) Memory loss
c) Weakness in the limbs
d) Loss of sensation in the face
Answer: a) Double vision (diplopia)
Rationale: Strokes in the basilar artery often affect areas responsible for vision, causing
diplopia.
What is diplopia?
a) Blurred vision
b) Loss of vision in one eye
c) Double vision
d) Tunnel vision
Answer: c) Double vision
Rationale: Diplopia refers to the perception of two images of a single object.
What best describes a non-critical infectious instrument?
a) Comes into contact with blood
,b) Comes into contact with intact skin
c) Is used in invasive procedures
d) Is used only once
Answer: b) Comes into contact with intact skin
Rationale: Non-critical instruments only touch intact skin and pose minimal risk for infection.
Which neurocutaneous syndrome includes brain, skin, and organ involvement?
a) Sturge-Weber syndrome
b) Huntington's disease
c) Alzheimer's disease
d) Multiple sclerosis
Answer: a) Sturge-Weber syndrome
Rationale: Neurocutaneous syndromes like Sturge-Weber can affect multiple organ systems
and the skin.
What is caused by a large lesion at the optic chiasm?
a) Tunnel vision
b) Loss of peripheral vision
c) Complete visual loss
d) Blurred vision
Answer: c) Complete visual loss
Rationale: A lesion at the optic chiasm interrupts both optic nerves, causing total visual loss.
What is homonymous hemianopsia?
a) Loss of the central visual field
b) Complete loss of vision in one eye
c) Loss of the left or right visual field in both eyes
d) Blurred vision in one eye
Answer: c) Loss of the left or right visual field in both eyes
Rationale: This condition is caused by damage to the visual pathways beyond the optic chiasm.
What is used to treat infantile spasms?
a) Phenobarbital
b) ACTH (adrenocorticotropic hormone)
c) Ethosuximide
d) Valproic acid
Answer: b) ACTH (adrenocorticotropic hormone)
Rationale: ACTH is the primary treatment for infantile spasms, helping to manage seizures.
, What condition may be indicated by blood in cerebrospinal fluid?
a) Brain tumor
b) Subarachnoid hemorrhage
c) Meningitis
d) Stroke
Answer: b) Subarachnoid hemorrhage
Rationale: Blood in the cerebrospinal fluid is a hallmark of subarachnoid hemorrhage due to
ruptured blood vessels.
Which blood vessel is most commonly involved in strokes?
a) Anterior cerebral artery
b) Middle cerebral artery
c) Basilar artery
d) Vertebral artery
Answer: b) Middle cerebral artery
Rationale: The middle cerebral artery supplies critical brain areas and is the most common site
for ischemic strokes.
Which medication is used for both GTC seizures and absence epilepsy?
a) Phenytoin
b) Ethosuximide
c) Carbamazepine
d) Valproic acid
Answer: b) Ethosuximide
