A nurse is reviewing the medical history of a client who has ischemic stroke. Which of the following conditions is the most common cause of ischemic stroke?

Atherosclerosis

Atrial fibrillation

Cerebral aneurysm

Arteriovenous malformation

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["A","B","C"]

Explanation

Choice A reason:

This is correct because bending forward at the waist can increase the pressure on the spinal discs and nerve roots, which can worsen radiculopathy symptoms.

Choice B reason:

This is correct because lifting heavy objects can also increase the pressure on the spinal discs and nerve roots, as well as strain the back muscles and ligaments, which can worsen radiculopathy symptoms.

Choice C reason:

This is correct because sitting for prolonged periods can reduce blood flow to the spinal discs and nerve roots, which can impair healing and worsen radiculopathy symptoms.

Choice D reason:

This is incorrect because swimming or water aerobics can be beneficial for clients with radiculopathy, as they can reduce stress on the spine, improve flexibility and strength, and relieve pain.

Choice E reason:

This is incorrect because walking or jogging can also be beneficial for clients with radiculopathy, as they can improve blood flow to the spine, enhance mood and well-being, and prevent deconditioning.

A. "The steroid will reduce the inflammation and swelling of the nerve root, which will decrease your pain and improve your function." B. "The local anesthetic will block the transmission of pain signals from the nerve root to your brain, which will provide you with temporary relief." C. "The combination of steroid and local anesthetic will shrink the size of the disc or bone spur that is compressing the nerve root, which will restore your mobility and sensation." D. "The injection will deliver medication directly to the affected area of your spine, which will have fewer side effects than oral or intravenous medications."

Correct Answer is A

Explanation

Choice A reason:

This is the correct answer because epidural steroid injections are used to treat radiculopathy by reducing inflammation and edema of the nerve root, which can relieve radicular pain and improve neurological function.

Choice B reason:

This is incorrect because local anesthetic alone can provide temporary pain relief by blocking nerve conduction, but it does not address the underlying cause of radiculopathy, which is nerve root compression.

Choice C reason:

This is incorrect because steroid and local anesthetic do not have any effect on the size or shape of the disc or bone spur that is compressing the nerve root. They only reduce inflammation and pain.

Choice D reason:

This is incorrect because although epidural injections may have fewer systemic side effects than oral or intravenous medications, they still have some risks and complications, such as infection, bleeding, nerve damage, or spinal headache.
