Neurological System Questions Questions
Question 1 of 5
A 71-year-old patient has had PD for 8 years and is currently taking pramipexole 1.5 mg three times a day and carbidopa/levodopa 25/100 mg four times a day. His wife claims that he is complaining of seeing spiders and bugs running across the floor and imaginary children in their house. The first thing to do is:
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The change in electrical charge that occurs in a neuron when a nerve impulse is transmitted is known as the:
Correct Answer: A
Rationale: An action potential is the rapid change in electrical charge that occurs in a neuron when a nerve impulse is transmitted. This process involves the depolarization of the neuron's membrane, where sodium ions rush into the cell, followed by repolarization, where potassium ions exit the cell. The action potential is the basis for neural communication and allows signals to travel quickly along the axon to the synapse, where neurotransmitters are released to communicate with other neurons.
Question 3 of 5
The ________ ________ consists of glands that secrete hormones:
Correct Answer: C
Rationale: The endocrine system consists of glands that secrete hormones into the bloodstream to regulate various bodily functions, such as metabolism, growth, and reproduction. Key glands include the pituitary, thyroid, and adrenal glands. Hormones act as chemical messengers, influencing target organs and tissues to maintain homeostasis. The endocrine system works closely with the nervous system to coordinate the body's responses to internal and external changes.
Question 4 of 5
If an individual suffers a traumatic event and has a neurological disorder that means they may be unable to recall anything from the moment of the injury or to retain memories of recent events. This is known as:
Correct Answer: A
Rationale: Anterograde amnesia refers to the inability to form new memories after the onset of amnesia, often due to brain injury or trauma. This condition severely impacts an individual's ability to retain information about recent events, while memories from before the injury may remain intact. It is commonly associated with damage to the hippocampus, a brain region critical for memory formation and consolidation.
Question 5 of 5
In most cases, when diagnosing a neurological disorder such as dementia, the clinician will endeavour to classify it according to its cause. Which of the following is a specific cause that has been identified?:
Correct Answer: D
Rationale: Neurological disorders like dementia can be caused by a variety of underlying conditions, including Alzheimer's disease, Pick's disease, and Parkinson's disease. Alzheimer's disease is the most common cause of dementia, characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain. Pick's disease is a rare form of dementia associated with frontotemporal lobe degeneration, while Parkinson's disease can lead to dementia due to the progressive loss of dopamine-producing neurons.
