A nurse is caring for a client who has cervical radiculopathy due to a herniated disc at C6-C7 level. Which of the following muscles should the nurse assess for weakness?

Choice A reason:

This is the correct answer because atherosclerosis is the main cause of ischemic stroke, as it leads to the formation of plaques that narrow the cerebral arteries and reduce blood flow to the brain.

Choice B reason:

This is incorrect because atrial fibrillation is a risk factor for ischemic stroke, but not the most common cause. Atrial fibrillation can cause embolic stroke, which occurs when a blood clot from the heart travels to the brain and blocks a cerebral artery.

Choice C reason:

This is incorrect because cerebral aneurysm is a cause of hemorrhagic stroke, not ischemic stroke. Cerebral aneurysm is a weak spot in a cerebral artery that can rupture and bleed into the brain.

Choice D reason:

This is incorrect because arteriovenous malformation is also a cause of hemorrhagic stroke, not ischemic stroke. Arteriovenous malformation is a congenital abnormality of the blood vessels in the brain that can leak or burst and cause bleeding.

Choice A reason:

This is a correct statement, as the PNS consists of cranial and spinal nerves that connect the CNS to the rest of the body and transmit sensory and motor signals.

Choice B reason:

This is a correct statement, as the PNS is divided into two subdivisions: the somatic nervous system (SNS) and the autonomic nervous system (ANS).

Choice C reason:

This is a correct statement, as the PNS controls voluntary movements of skeletal muscles and provides sensory feedback from the skin, joints, and muscles through the SNS.

Choice D reason:

This is an incorrect statement, as this is the function of the ANS, which is a subdivision of the PNS. The ANS regulates involuntary functions of smooth muscles, cardiac muscles, and glands through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
