Health Assessment Neurological System Questions Questions
Question 1 of 5
A 70-year-old patient taking carbidopa/levodopa 25/100 mg three times a day for PD is experiencing end-of-dose wearing off. The best next step is to:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What part of a neuron is responsible for receiving information?
Correct Answer: C
Rationale: Dendrites are the part of a neuron responsible for receiving information from other neurons. They are branched structures that extend from the cell body and contain receptors for neurotransmitters. When neurotransmitters bind to these receptors, they generate electrical signals that travel toward the cell body, initiating communication between neurons. Dendrites play a crucial role in integrating incoming signals and determining whether the neuron will fire an action potential.
Question 3 of 5
The poison curare is a(n) ________ for the neurotransmitter acetylcholine.
Correct Answer: A
Rationale: Curare is an antagonist for the neurotransmitter acetylcholine, meaning it blocks acetylcholine receptors at the neuromuscular junction. This prevents acetylcholine from binding to its receptors and initiating muscle contraction, leading to paralysis. Curare has been used historically as a poison and in medical procedures to induce muscle relaxation. Its action highlights the importance of acetylcholine in muscle function and the effects of receptor blockade.
Question 4 of 5
The brain's ability to change in response to experience or damage is called:
Correct Answer: C
Rationale: Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections in response to learning, experience, or injury. This adaptability allows the brain to compensate for damage and recover lost functions. Neuroplasticity is the basis for learning and memory and plays a crucial role in rehabilitation after brain injury. It highlights the brain's remarkable capacity for change and adaptation.
Question 5 of 5
In the United States of America one most common neuropsychological tests used is known as:
Correct Answer: B
Rationale: The Halstead-Reitan Neuropsychological Test Battery is one of the most commonly used neuropsychological assessments in the United States. It consists of a series of tests designed to evaluate brain and nervous system functioning, including measures of cognitive, motor, and sensory abilities. This battery is particularly useful for diagnosing brain damage, assessing the severity of neurological disorders, and planning rehabilitation strategies.
