- Epidural hematoma
- Diffuse axonal injury
- Concussion only
- Post-traumatic hydrocephalus
Reveal correct answer and explanation
Correct answer: A. Epidural hematoma
Epidural hematoma may follow a lucid interval, although it is not universal.
Question 12. A lens-shaped hyperdense extra-axial collection on noncontrast head CT is typical of:
- Subdural hematoma
- Epidural hematoma
- Subarachnoid hemorrhage
- Intraventricular hemorrhage
Reveal correct answer and explanation
Correct answer: B. Epidural hematoma
Epidural blood is classically biconvex because sutures constrain its spread.
Question 13. Which vessel is classically injured with temporal extradural hemorrhage?
- Middle meningeal artery
- Anterior cerebral artery
- Internal jugular vein
- Superior sagittal sinus in every case
Reveal correct answer and explanation
Correct answer: A. Middle meningeal artery
A temporal bone fracture can tear the middle meningeal artery; some epidural hematomas are venous.
Question 14. A crescent-shaped extra-axial collection that crosses sutures most suggests:
- Epidural hematoma
- Subdural hematoma
- Intraparenchymal hemorrhage
- Intraventricular hemorrhage
Reveal correct answer and explanation
Correct answer: B. Subdural hematoma
Subdural collections commonly extend across sutures but are constrained by dural reflections.
Question 15. A typical mechanism of traumatic acute subdural hematoma is injury to:
- Bridging veins
- Ophthalmic artery
- Facial artery
- Vertebral venous plexus only
Reveal correct answer and explanation
Correct answer: A. Bridging veins
Bridging veins are often implicated; acute subdural hematomas can also result from cortical vessel injuries.
Question 16. Which population has increased susceptibility to chronic subdural hematoma after minor trauma?
- Young adults with normal coagulation exclusively
- Older people with brain atrophy or anticoagulant use
- Only infants with no trauma
- Only marathon runners
Reveal correct answer and explanation
Correct answer: B. Older people with brain atrophy or anticoagulant use
Cerebral atrophy and antithrombotic therapy increase risk; chronic subdural blood may evolve over weeks.
Question 17. Which description best identifies traumatic subarachnoid hemorrhage on CT?
- Blood tracking within sulci and cisterns
- A strictly biconvex epidural collection
- Only an intraventricular fluid level
- A hypodense scalp collection

- Routine discharge
- Surgical evacuation regardless of GCS
- Elective outpatient MRI
- Treat with aspirin
Reveal correct answer and explanation
Correct answer: B. Surgical evacuation regardless of GCS
Epidural hematoma greater than 30 cm³ merits surgical evacuation irrespective of GCS under BTF surgical guidance.
Question 34. A patient has an acute SDH with 7 mm midline shift but only 6 mm hematoma thickness. Which is true?
- No neurosurgical concern because thickness is under 10 mm
- Midline shift independently satisfies a guideline surgical criterion
- Repeat CT only after one month
- It is an epidural collection
Reveal correct answer and explanation
Correct answer: B. Midline shift independently satisfies a guideline surgical criterion
Shift greater than 5 mm independently supports operative evacuation for acute SDH.
Question 35. Which statement best describes hypertonic saline and mannitol for elevated ICP?
- Neither can change ICP
- Both are hyperosmolar options, with choice depending on physiology and local protocol
- Both are routinely used in every mild TBI
- Both replace neurosurgical consultation
Reveal correct answer and explanation
Correct answer: B. Both are hyperosmolar options, with choice depending on physiology and local protocol
Hyperosmolar therapy can reduce ICP; the agents differ in hemodynamic and electrolyte effects.
Question 36. What is the major danger of sustained prophylactic hyperventilation in early severe TBI?
- It always raises PaCO2
- Cerebral vasoconstriction may reduce cerebral blood flow
- It removes need for oxygenation
- It eliminates brain edema permanently
Reveal correct answer and explanation

Set 4: Questions 76–100
Question 76. The most appropriate approach to persistent dizziness after concussion is:
- Assess vestibular, ocular and cervical contributors and target therapy
- Assume it is always psychogenic
- Prescribe permanent bed rest
- Ignore balance findings
Reveal correct answer and explanation
Correct answer: A. Assess vestibular, ocular and cervical contributors and target therapy
Vestibular/ocular assessment can direct specific rehabilitation and exclusion of central red flags.
Question 77. Which is a key difference between post-traumatic epilepsy and an early provoked seizure?
- Epilepsy relates to enduring predisposition to unprovoked seizures
- Every seizure within 24 hours proves epilepsy
- Late seizures never occur
- Antiseizure prophylaxis eliminates all future epilepsy
Reveal correct answer and explanation
Correct answer: A. Epilepsy relates to enduring predisposition to unprovoked seizures
An early seizure is an acute symptomatic event; late unprovoked seizures can indicate enduring epileptogenic risk.
Question 78. In a patient receiving mannitol or hypertonic saline, which parameter needs active monitoring?
- Electrolytes, osmolality and renal/hemodynamic status
- Hair color
- Pupil color only
- Height alone
Reveal correct answer and explanation
Correct answer: A. Electrolytes, osmolality and renal/hemodynamic status
Hyperosmolar therapies require monitoring for sodium disorders, renal dysfunction and circulatory effects.
Question 79. Which condition can cause neurologic worsening during the first days after contusion?
- Hemorrhagic progression and edema
- Instant disappearance of all lesions
- Only delayed skull calcification
- Peripheral neuropathy exclusively
Reveal correct answer and explanation
Correct answer: A. Hemorrhagic progression and edema
Contusions can blossom and edema can increase, motivating serial neurological evaluation.
Question 80. Why is intensive cerebral perfusion monitoring relevant after severe TBI?
- Hypotension and high ICP can cause secondary ischemia
- Primary injury is reversible by monitoring alone
- Cerebral blood flow is independent of pressure
- ICP and MAP have no relationship
Reveal correct answer and explanation
Correct answer: A. Hypotension and high ICP can cause secondary ischemia
CPP represents the pressure gradient driving cerebral perfusion, although autoregulation modifies flow.
Question 81. In a patient with refractory ICP elevation, which intervention can reduce intracranial volume mechanically?
- Decompressive craniectomy in selected cases
- Oral antibiotics alone
- Passive exercise alone
- Routine lumbar puncture
Reveal correct answer and explanation
Correct answer: A. Decompressive craniectomy in selected cases
Cranial decompression may control refractory intracranial hypertension; patient selection and functional outcome tradeoffs are critical.
Question 82. What is the correct goal for routine early prophylactic anticoagulation decisions after TBI?
- Balance venous thromboembolism prevention against hemorrhage stability
- Give thrombolytic therapy to every patient
- Avoid VTE assessment entirely
- Start full-dose anticoagulation indiscriminately
Reveal correct answer and explanation
Correct answer: A. Balance venous thromboembolism prevention against hemorrhage stability
Timing depends on stability of intracranial bleeding, injury severity and neurosurgical guidance.
Question 83. An older TBI survivor is experiencing falls because of inattention and poor dual-task gait. Best rehabilitation plan?
- Combine gait/balance training with graded cognitive dual-task practice and safety strategies
- Prescribe walking alone on unsafe terrain
- Use only bed rest
- Ignore cognitive deficits
Reveal correct answer and explanation
Correct answer: A. Combine gait/balance training with graded cognitive dual-task practice and safety strategies
Integrated mobility and attention training with graded challenge addresses real-world fall risk.
Question 84. A survivor has poor self-awareness of deficits and rejects safety precautions. Best strategy?

- Assume intact insight because speech is fluent
- Immediate unsupervised discharge
- Stop rehabilitation
Reveal correct answer and explanation
Correct answer: A. Structured feedback, goal-setting and caregiver-supported monitoring
Impaired self-awareness can undermine adherence and safety; metacognitive intervention may help.
Question 85. Which tool best maps progress from acute TBI severity to later disability?
- Use GCS acutely and GOSE for follow-up function
- Repeat only admission GCS for years
- Use an isolated serum marker
- Use only skull X-ray
Reveal correct answer and explanation
Correct answer: A. Use GCS acutely and GOSE for follow-up function
Acute severity and long-term functional outcome are distinct domains requiring different instruments.
Question 86. A patient after severe TBI develops fever and worsening spasticity. Initial rehabilitation reasoning should prioritize:
- Search for infection, pain and other noxious triggers
- Escalate antispastic medication without examination
- Assume irreversible neurologic progression
- Discharge immediately
Reveal correct answer and explanation
Correct answer: A. Search for infection, pain and other noxious triggers
Infection, constipation, urinary retention and pain can trigger increased tone and autonomic dysregulation.
Question 87. Early rehabilitation referral in medically stable severe TBI is important because:
- Function, swallowing, positioning and family needs can be addressed alongside acute treatment
- Rehabilitation must wait until full consciousness
- It replaces neurocritical monitoring
- It removes need for nursing care
Reveal correct answer and explanation
Correct answer: A. Function, swallowing, positioning and family needs can be addressed alongside acute treatment
Early multidisciplinary rehabilitation supports prevention and recovery without superseding physiologic safety.
Question 88. The most appropriate management of a patient who is minimally conscious and has severe limb contracture risk is:
- Multidisciplinary positioning and regular reassessment of consciousness and range
- Assume rehabilitation has no role
- Use only maximal intensity strengthening
- Avoid caregiver education
Reveal correct answer and explanation
Correct answer: A. Multidisciplinary positioning and regular reassessment of consciousness and range
DoC care includes standardized repeated assessment and prevention of secondary musculoskeletal complications.
Question 89. A patient after frontal TBI becomes impulsive and gives socially inappropriate responses. Principal affected system?
- Executive and behavioral regulation networks
- Pure vestibular reflex arc
- Peripheral neuromuscular junction
- Dorsal column sensory pathways exclusively
Reveal correct answer and explanation
Correct answer: A. Executive and behavioral regulation networks
Frontal-subcortical network injury can impair inhibition, decision-making and social behavior.
Question 90. Which symptom cluster raises concern for neurogenic bladder complications in a dependent TBI patient?
- Retention, recurrent urinary infections and incontinence
- Improving bowel regularity only
- Normal post-void residual
- Stable continence
Reveal correct answer and explanation
Correct answer: A. Retention, recurrent urinary infections and incontinence
Bladder assessment can identify retention, infection and practical continence needs.
Question 91. In a medically stable TBI patient with early orthostatic hypotension, the safest approach is:
- Graded upright tolerance training with blood pressure monitoring
- Immediate unsupervised standing for an hour
- Avoid all future mobilization
- Ignore dizziness
Reveal correct answer and explanation
Correct answer: A. Graded upright tolerance training with blood pressure monitoring
Progressive head-up positioning and hemodynamic observation reduce syncope risk during mobilization.
Question 92. Which patient-centered goal is most appropriate for rehabilitation planning?
- Independently transfer from bed to chair with safe technique
- Normalize every scan by tomorrow
- Guarantee no future cognitive symptoms
- Avoid measuring function
Reveal correct answer and explanation
Correct answer: A. Independently transfer from bed to chair with safe technique
Specific measurable functional goals guide interdisciplinary treatment and reassessment.
Question 93. What distinguishes a multidisciplinary TBI rehabilitation team from isolated physical therapy?
- Coordinated mobility, cognition, communication, self-care and psychosocial care
- Only exercise repetition
- Avoidance of family meetings
- No standardized outcome measures
Reveal correct answer and explanation
Correct answer: A. Coordinated mobility, cognition, communication, self-care and psychosocial care
Team rehabilitation integrates physiatry, PT, OT, SLP, psychology, nursing and social services.
Question 94. For cognitive rehabilitation, what is meant by generalization?
- Applying a learned strategy beyond the training task to real situations
- Memorizing test answers only
- Improving only the practiced computer score
- Ignoring everyday participation
Reveal correct answer and explanation
Correct answer: A. Applying a learned strategy beyond the training task to real situations
Transfer of training to real-world tasks is central to clinically useful rehabilitation.
Question 95. Which feature is a more appropriate marker of readiness to leave inpatient rehabilitation?
- Safe function with feasible supports and a coordinated follow-up plan
- Normal CT only
- Absence of every symptom
- Age under 50
Reveal correct answer and explanation
Correct answer: A. Safe function with feasible supports and a coordinated follow-up plan
Disposition considers current assistance needs, caregiver capacity, risks and access to continuing care.
Question 96. A patient develops persistent excessive daytime sleepiness several months after TBI. What is appropriate?
- Assess sleep disorders, medicines, mood and endocrine contributors
- Assume the complaint is malingering
- Prescribe lifelong sedatives automatically
- Ignore impact on driving
Reveal correct answer and explanation
Correct answer: A. Assess sleep disorders, medicines, mood and endocrine contributors
Sleep-wake disturbance after TBI is multifactorial; assessment targets reversible causes and functional consequences.
Question 97. Which statement regarding return to sport after concussion is correct?
- Return should be staged and medically guided, with no contact risk during persisting concerning symptoms
- Immediate same-day return is always acceptable
- Prolonged absolute rest is universally required
- Symptom recurrence must always be ignored
Reveal correct answer and explanation
Correct answer: A. Return should be staged and medically guided, with no contact risk during persisting concerning symptoms
A graduated, individualized return-to-sport protocol reduces risks of premature collision exposure.
Question 98. In a patient after TBI with poor insight, what increases the reliability of function assessment?
- Combining patient report with observed performance and appropriate collateral history
- Patient self-report alone always
- Using only the initial CT
- Avoiding real-world task observation
Reveal correct answer and explanation
Correct answer: A. Combining patient report with observed performance and appropriate collateral history
Performance-based assessment and information from informed caregivers help characterize function where awareness is impaired.
Question 99. A TBI patient has difficulty managing medications despite intact motor strength. Which service is central to functional intervention?
- Occupational therapy with cognitive strategy training
- Only lower-limb stretching
- Orthopedic casting
- Isolated visual acuity testing
Reveal correct answer and explanation
Correct answer: A. Occupational therapy with cognitive strategy training
OT can assess instrumental ADLs and build compensatory systems for safe medication management.
Question 100. Which long-term endpoint is MOST consistent with a rehabilitation perspective on TBI?
- Meaningful independence and participation compatible with individual goals
- CT normalization alone
- Absolute freedom from all fatigue
- A single motor score exclusively
Reveal correct answer and explanation
Correct answer: A. Meaningful independence and participation compatible with individual goals

Physical Medicine & Rehabilitation
FAQs
What is Physical Medicine and Rehabilitation?
Physical Medicine and Rehabilitation (PM&R), also known as physiatry, is an allopathic medical specialty that involves restoring function for a person who has been disabled by disease, disorder, or injury. It provides integrated, multidisciplinary care addressing physical, emotional, medical, vocational, and social needs.
Who is a “Physiatrist”?
A physiatrist is a physician specializing in physical medicine and rehabilitation. (In India: MBBS followed by MD/DNB in PMR.)
What is Rehabilitation?
Rehabilitation is the process of helping a person achieve the highest level of function, independence, and quality of life possible. It does not undo damage but restores optimal health, functioning, and well-being.
Is PM&R only for people with disabilities?
No. PM&R serves anyone experiencing a decline in physical function—from athletes with injuries to elderly individuals recovering from surgery, falls, or pain.
Can physiatrists perform surgery?
Yes. In India, physiatrists perform rehabilitation surgeries such as deformity corrections, tendon transfers, and revision of amputations.
How does PM&R help in managing chronic pain?
Physiatrists use a multimodal approach—evaluation, diagnosis, medication, therapy, injections (e.g., nerve blocks, trigger point/joint injections), and lifestyle modifications—to reduce pain and improve daily function.
What conditions do physiatrists treat?
Common conditions include stroke, spinal cord injuries, traumatic brain injury, cerebral palsy, amputations, sports injuries, chronic musculoskeletal pain, post-surgical rehabilitation, osteoarthritis, osteoporosis, and more.
