Loss of motor neurons in the anterior horn of the spinal cord and loss of motor nuclei of the lower brainstem
All of the above
The Correct Answer is C
Choice A: Loss of motor neurons in the brain is not a complete definition of ALS, as it does not include the loss of motor neurons in the spinal cord and brainstem.
Choice B: Loss of sensory neurons in the anterior horn of the spinal cord is not a correct definition of ALS, as it involves sensory neurons, not motor neurons.
Choice C: Loss of motor neurons in the anterior horn of the spinal cord and loss of motor nuclei of the lower brainstem is a correct definition of ALS, as it describes the progressive degeneration and death of both upper and lower motor neurons that control voluntary muscle movements²⁴.

Choice C: Have patient sit upright 90 degrees in bed or chair is correct, as this position helps the patient align their head and neck and use gravity to facilitate swallowing and prevent aspiration.

Correct Answer is D
Explanation
Choice a) is incorrect because Parkinson's disease is not an acute condition, but a chronic one that develops over time.
Choice b) is incorrect because Parkinson's disease is not associated with decreased levels of acetylcholine, but with decreased levels of dopamine. Acetylcholine is another neurotransmiter that is involved in muscle movement and memory.
Choice c) is incorrect because Parkinson's disease is not an acute condition, nor is it associated with decreased levels of acetylcholine.
Choice d) is correct because Parkinson's disease is a slow, progressive neurologic movement disorder that results from the loss of dopamine-producing cells in the brain. Dopamine is a neurotransmiter that helps regulate movement, mood, and motivation.
