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?
Biceps brachii.
Triceps brachii.
Deltoid.
Trapezius.
The Correct Answer is B
Choice A reason:
This is incorrect because biceps brachii is innervated by C5-C6 nerve roots, which are not affected by a herniated disc at C6-C7 level.
Choice B reason:
This is the correct answer because triceps brachii is innervated by C6-C8 nerve roots, which are affected by a herniated disc at C6-C7 level.
Choice C reason:
This is incorrect because deltoid is innervated by C5-C6 nerve roots, which are not affected by a herniated disc at C6-C7 level.
Choice D reason:

Correct Answer is A
Explanation
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.
Correct Answer is A
Explanation
Choice A reason:
This is the correct answer because Spurling's test is used to diagnose cervical radiculopathy by reproducing radicular pain with neck extension, lateral flexion, and compression. A positive result indicates nerve root compression by a herniated disc, osteophyte, or other lesion.
Choice B reason:
This is incorrect because straight leg raise test is used to diagnose lumbar radiculopathy by reproducing radicular pain with hip flexion and knee extension. A positive result indicates nerve root compression by a herniated disc or other lesion in the lower back.
Choice C reason:
This is incorrect because Tinel's sign is used to diagnose peripheral neuropathy by reproducing tingling or paresthesia with tapping over a damaged nerve. A positive result indicates nerve regeneration or irritation by a scar, tumor, or other lesion.
Choice D reason:
This is incorrect because Phalen's test is used to diagnose carpal tunnel syndrome by reproducing numbness or tingling in the median nerve distribution with wrist flexion for 60 seconds. A positive result indicates median nerve compression by a thickened flexor retinaculum or other lesion in the wrist.
