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

Choice A reason:

This is a correct statement. The central nervous system (CNS) is responsible for processing sensory information, generating motor commands, and regulating cognitive and emotional functions.

Choice B reason:

This is an incorrect statement. The peripheral nervous system (PNS) consists of the cranial nerves, spinal nerves, and ganglia that connect the CNS to the rest of the body.

Choice C reason:

This is a correct statement. The autonomic nervous system (ANS) regulates involuntary functions of smooth muscles, cardiac muscles, and glands. It has two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).

Choice D reason:

This is a correct statement. The sympathetic nervous system (SNS) prepares the body for stress or emergency situations by increasing heart rate, blood pressure, respiratory rate, and blood glucose levels. It also dilates the pupils, bronchi, and blood vessels to skeletal muscles.

Choice A reason:

This is an incorrect answer. Elevated CSF protein level is a common finding in clients who have GBS due to demyelination of peripheral nerves. It does not indicate infection or inflammation and does not require immediate intervention.

Choice B reason:

This is an incorrect answer. Decreased serum CK level is a normal finding in clients who have GBS because CK is released from damaged muscle tissue and GBS does not affect muscle cells directly.

Choice C reason:

This is a correct answer. Increased CSF WBC count indicates infection or inflammation in the central nervous system (CNS), which can be a complication of GBS or a sign of another condition such as meningitis or encephalitis. The nurse should report this finding to the provider for further evaluation and treatment.

Choice D reason:

This is an incorrect answer. Decreased serum sodium level can occur.
