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","D","E"]
Explanation
Choice A reason: This is correct because avoiding swimming underwater can help prevent the worsening of Meniere's disease. Meniere's disease is a disorder of the inner ear that causes episodes of vertigo, tinnitus, hearing loss, and fullness in the ear. Swimming underwater can increase pressure in the ear and trigger an attack. The nurse should advise the client to avoid activities that involve changes in altitude or pressure, such as flying, diving, or climbing.
Choice B reason: This is incorrect because wearing earphones when in crowded places can worsen Meniere's disease. Earphones can increase noise exposure and damage hearing, which is already impaired by Meniere's disease. The nurse should advise the client to avoid loud noises and use hearing aids if needed.
Choice C reason: This is incorrect because keeping eyes open during an acute attack can increase vertigo and nausea. Vertigo is a sensation of spinning or moving when still, which can be caused by Meniere's disease. Keeping eyes open can make vertigo worse by creating a visual mismatch with vestibular signals from the inner ear. The nurse should advise the client to close their eyes or focus on a stationary object during an attack.
Choice D reason: This is correct because sitting or lying down if whirling occurs can help prevent falls or injuries due to vertigo. Whirling is another term for vertigo, which can affect balance and coordination. Sitting or lying down can reduce movement and stabilize posture during an attack. The nurse should advise
the client to avoid driving or operating machinery when experiencing vertigo.
Choice E reason: This is correct because we do not know the exact cause of Meniere's disease. Meniere's disease is thought to be related to abnormal fluid balance or pressure in the inner ear, but what triggers this condition is unknown. The nurse should educate the client about possible risk factors, such as genetics, infections, allergies, autoimmune disorders, or head trauma, but also acknowledge the uncertainty and variability of the disease.
Choice F reason: This is incorrect because damage to the ear from excess noise is not the cause of Meniere's disease. Damage to the ear from excess noise can cause noise-induced hearing loss, which is a type of sensorineural hearing loss that affects the cochlea or the auditory nerve. Meniere's disease is a type of mixed hearing loss that affects both the cochlea and the middle ear. The nurse should not confuse or misinform the client about the cause of their condition.
Correct Answer is B
Explanation
Choice A Reason: This is incorrect because inability to recognize any words may indicate a problem with the auditory cortex, which is the part of the brain that processes sound, not the inner ear. The inner ear consists of the cochlea, which converts sound waves into nerve impulses, and the vestibular system, which helps with balance and orientation.
Choice B Reason: This is correct because loss of balance is a common symptom of an inner ear infection. An inner ear infection can cause inflammation and fluid buildup in the vestibular system, which can disrupt the sense of equilibrium and cause vertigo, dizziness, or nausea.
Choice C Reason: This is incorrect because twitching of the cheek may indicate a problem with the facial nerve, which controls the muscles of facial expression, not the inner ear. The facial nerve runs close to the inner ear, but it is not part of it.
Choice D Reason: This is incorrect because lack of air sound may indicate a problem with the outer or middle ear, which transmit sound waves to the inner ear, not the inner ear itself. The outer ear consists of the pinna and the ear canal, and the middle ear consists of the eardrum and the ossicles.
