Question 1

How long should you wait to get an LP before giving antibiotics?

Accepted Answer

C

Question 2

Which CSF finding is incorrect?

Accepted Answer

In viral meningitis, the glucose levels in the CSF are usually normal or slightly decreased, not low, and the protein levels might be slightly elevated. The statement in E is more characteristic of bacterial meningitis, where glucose levels are typically low due to bacterial consumption and protein levels are elevated due to the inflammatory response.

Question 3

Which statement is incorrect about prophylaxis in meningitis?

Accepted Answer

Prophylaxis is often recommended for the index case in certain situations to prevent further spread, especially in cases of meningococcal meningitis.

Question 4

Which of the signs or symptoms below would concern you that the cause of a patients vertigo was central?

Accepted Answer

Vertical nystagmus is a sign that could indicate a central cause of vertigo, such as a brainstem or cerebellar lesion, rather than a peripheral cause. Peripheral causes of vertigo, like benign paroxysmal positional vertigo (BPPV), Meniere's disease, or vestibular neuritis, typically do not cause vertical nystagmus.

Question 5

Which of these is not consistent with vestibular neuronitis?

Accepted Answer

Dysarthria is not consistent with vestibular neuronitis because this condition primarily affects balance and spatial orientation, not speech production.

Question 6

What is NOT true of Guillian Barre Syndrome?

Accepted Answer

Guillain-Barre Syndrome (GBS) typically presents with symptoms that are more pronounced in the lower extremities (legs) than in the upper extremities (arms), including both motor weakness and sensory loss. The statement that there is peripheral sensory loss greater in the arms than in the legs is not true of GBS, as the condition usually affects the legs more severely or earlier than the arms.

Question 7

Which statement is false regarding Bells Palsy?

Accepted Answer

The answer of Which statement is false regarding Bells Palsy?
...

Question 8

Which of the drugs below is not known to cause an exacerbation of myasthenia gravis?

Accepted Answer

Penicillin is not known to exacerbate myasthenia gravis. Myasthenia gravis is an autoimmune neuromuscular disorder, and certain medications can exacerbate its symptoms. While drugs like chlorpromazine (an antipsychotic) and lithium (used in bipolar disorder) can potentially worsen myasthenia gravis, penicillin, an antibiotic, does not have this association.

Question 9

Which is not a feature of myasthenia gravis?

Accepted Answer

Myasthenia gravis is caused by antibodies formed against acetylcholine receptors at the neuromuscular junction, not against acetylcholinesterase.

Question 10

Which statement is FALSE about MS?

Accepted Answer

In MS, CSF protein and gammaglobulin levels are typically increased, not reduced. This is part of the immune response associated with the disease.

Question 11

A patient presents with right sided arm weakeness and a R facial droop with aphasia. Which artery distribution is the likely to be the cause of her stoke?

Accepted Answer

The symptoms of right-sided arm weakness, right facial droop, and aphasia (difficulty in speaking) suggest that the stroke is affecting areas of the brain responsible for motor function and speech. These functions are primarily controlled by the left hemisphere of the brain in most people. The Middle Cerebral Artery (MCA) supplies blood to the areas of the brain that control these functions. Therefore, a stroke in the left MCA territory would likely cause these symptoms.

Question 12

Which CSF finding is incorrect?

Accepted Answer

...

Question 13

Which of the signs or symptoms below would concern you that the cause of a patients vertigo was central?

Accepted Answer

Vertical nystagmus is a sign that could indicate a central cause of vertigo, such as a brainstem or cerebellar lesion, rather than a peripheral cause. Peripheral causes of vertigo, like benign paroxysmal positional vertigo (BPPV), Meniere's disease, or vestibular neuritis, typically do not cause vertical nystagmus.
