Question 1

Which of the following best describes the Monro-Kellie hypothesis regarding intracranial pressure?

Accepted Answer

The cranial vault contains blood, brain tissue, and cerebrospinal fluid, and an increase in one component must be compensated by a decrease in another to maintain normal pressure.

Question 2

A patient presents with sudden weakness on one side of the body, slurred speech, and facial droop. CT scan reveals an arterial occlusion in the middle cerebral artery. Which type of cerebrovascular accident (CVA) is most likely?

Accepted Answer

Thrombotic stroke

Question 3

Which neuromodulator is primarily inhibitory in the modulation of pain within the central nervous system?

Accepted Answer

GABA

Question 4

A patient with Parkinson’s disease is most likely to exhibit which of the following clinical manifestations?

Accepted Answer

Resting tremor, rigidity, bradykinesia, and postural disturbance

Question 5

Which of the following is a key difference between nociception and pain?

Accepted Answer

Nociception is a third-person, stimulus-related process, while pain is a first-person, perception-related experience.

Question 6

A patient with multiple sclerosis (MS) is experiencing blurred vision, hand tremor, and loss of bladder control. Which underlying pathophysiological process is responsible for these symptoms?

Accepted Answer

Autoimmune destruction of oligodendrocytes leading to demyelination in the CNS

Question 7

Which of the following best describes referred pain?

Accepted Answer

Pain perceived as occurring in a region of the body topographically distinct from the region in which the source of pain is located.

Question 8

A patient with diabetic neuropathy reports burning pain in their feet that persists for months and does not respond to conventional analgesics. What type of pain is this?

Accepted Answer

Neuropathic pain

Question 9

Which equation best represents the relationship described by the Monro-Kellie hypothesis?

Accepted Answer

$$V_{brain} + V_{blood} + V_{CSF} = constant$$

Question 10

Which of the following is a common manifestation of increased intracranial pressure (ICP)?

Accepted Answer

Ischaemia due to reduced or interrupted blood flow

Question 11

A patient is prescribed morphine for severe pain following surgery. Which step of the pain management ladder does this represent?

Accepted Answer

Step 2: Opioid + non-opioid

Question 12

Which of the following is a primary excitatory neuromodulator involved in pain transmission?

Accepted Answer

Substance P

Question 13

A patient with Parkinson’s disease is treated with levodopa. What is the primary mechanism of action of this drug?

Accepted Answer

It acts as a dopamine agonist to compensate for loss of dopaminergic neurons.

Question 14

Which of the following is NOT a typical symptom of multiple sclerosis?

Accepted Answer

Sudden onset of paralysis and aphasia

Question 15

Which of the following best explains why pain motivates people to seek medical help?

Accepted Answer

Pain serves as a conditioning stimulus to avoid further damage and encourages healing behaviors.

Question 16

A patient with a history of atrial fibrillation and poorly controlled diabetes is at increased risk for which type of stroke?

Accepted Answer

Embolic stroke

Question 17

Which of the following best describes the role of endorphins in pain modulation?

Accepted Answer

Endorphins bind to opioid receptors and inhibit pain transmission.

Question 18

A patient with post-herpetic neuralgia is experiencing persistent pain months after the initial infection. Which type of pain is this?

Accepted Answer

Peripheral neuropathic pain

Question 19

Which of the following is a common rehabilitation goal for patients recovering from a cerebrovascular accident (stroke)?

Accepted Answer

Restoration of normal social roles and functional independence

Question 20

Which of the following formulas best represents the calculation of cerebral perfusion pressure (CPP) in the context of increased intracranial pressure (ICP)?

Accepted Answer

$$CPP = MAP - ICP$$
