A nurse is teaching a client about the functions of the central nervous system (CNS). Which of the following statements by the client indicates a need for further teaching?

Choice A reason:

This is a correct answer, as the medication increases dopamine levels in the brain, which helps to improve the symptoms of Parkinson's disease, such as tremors, rigidity, and bradykinesia.

Choice B reason:

This is an incorrect answer, as the medication does not decrease acetylcholine levels in the brain, but rather increases dopamine levels. Acetylcholine is another neurotransmitter that controls muscle contraction, learning, and memory.

Choice C reason:

This is an incorrect answer, as the medication does not increase serotonin levels in the brain, but rather increases dopamine levels. Serotonin is another neurotransmitter that controls mood, sleep, and appetite.

Choice D reason:

This is an incorrect answer, as the medication does not decrease glutamate levels in the brain, but rather increases dopamine levels. Glutamate is another neurotransmitter that controls excitatory signals in the brain.

Choice A reason:

This is a correct statement, as the CNS receives sensory information from various receptors in the body and interprets it.

Choice B reason:

This is a correct statement, as the CNS initiates and coordinates motor commands to control voluntary and involuntary movements.

Choice C reason:

This is a correct statement, as the CNS is involved in higher cognitive functions such as memory, learning, reasoning, and emotions.

Choice D reason:

This is an incorrect statement, as this is the function of the PNS. The PNS consists of cranial and spinal nerves that connect the CNS to the rest of the body and transmit sensory and motor signals.
