A nurse is assessing a client who has suffered a traumatic brain injury. When the nurse applies a stimuli to the client, which of the following responses by the client indicates that the client has suffered an extensive cervical spine injury?
Nystagmus
Decorticate positioning
Lack of any response
Decerebrate positioning
The Correct Answer is D
Choice A Reason: This is incorrect because nystagmus is not a response to stimuli, but a condition that causes involuntary eye movements. Nystagmus can be caused by various factors, such as inner ear disorders, brain lesions, or drug toxicity, but not necessarily by cervical spine injury.
Choice B Reason: This is incorrect because decorticate positioning is a response to stimuli that indicates damage to the cerebral cortex or the corticospinal tract. Decorticate positioning is characterized by flexion of the arms and extension of the legs. It does not indicate cervical spine injury, which affects the spinal cord below the brainstem.
Choice C Reason: This is incorrect because lack of any response to stimuli can indicate various levels of brain damage or coma, but not specifically cervical spine injury. Lack of any response can also be influenced by other factors, such as sedation, hypothermia, or shock.
Choice D Reason: This is correct because decerebrate positioning is a response to stimuli that indicates damage to the brainstem or the upper cervical spine. Decerebrate positioning is characterized by extension and outward rotation of the arms and legs. It indicates a severe and life-threatening injury that can impair vital functions, such as breathing and blood pressure.

Correct Answer is A
Explanation
Choice A reason: This is the correct answer because bacterial meningitis is a medical emergency that requires immediate antibiotic therapy to prevent complications and death.
Choice B reason: This is incorrect because documenting intake and output is not a priority action for a child with bacterial meningitis. Fluid balance is important, but not as urgent as antibiotic administration.
Choice C reason: This is incorrect because reducing environmental stimuli is a supportive measure that can help reduce headache and photophobia, but it is not a priority action for a child with bacterial meningitis. The nurse should focus on preventing infection spread and monitoring for signs of increased intracranial pressure.
Choice D reason: This is incorrect because maintaining seizure precautions is a preventive measure that can help protect the child from injury, but it is not a priority action for a child with bacterial meningitis. The nurse should administer anticonvulsants as prescribed and observe for seizure activity, but the main goal is to treat the infection.
Correct Answer is B
Explanation
Choice A Reason: Depth perception is the ability to judge the distance and position of objects in three-dimensional space. Depth perception is assessed by asking the client to touch the tip of a pen or pencil held by the nurse, or by using a stereopsis test.
Choice B Reason: Peripheral vision is the ability to see objects and movements outside the direct line of vision. Peripheral vision is assessed by asking the client to shake the hand of the nurse, who stands at an angle to the client's side, or by using a confrontation test.
Choice C Reason: Color deficit is the inability to distinguish certain colors or shades of colors. Color deficit is assessed by asking the client to identify numbers or shapes on a color plate test, such as the Ishihara test.
Choice D Reason: Double vision is the perception of two images of a single object. Double vision is assessed by asking the client to cover one eye and look at an object, then switch eyes and compare the images, or by using a cover-uncover test.
