A client's chart indicates that they are legally blind. Which of the following is the definition of legally blind?

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.

Choice A reason: This is incorrect because using sign language when communicating with the client is not an appropriate action for the nurse to take. Sign language is a form of communication that uses hand gestures, facial expressions, and body movements. It is not a universal language and requires training and practice. The nurse should not assume that the client knows or prefers sign language unless they have indicated so.

Choice B reason: This is incorrect because speaking loudly and into the client's good ear is not an appropriate action for the nurse to take. Speaking loudly can distort the sound quality and cause discomfort or irritation to the client. Speaking into the client's good ear can also create a sense of imbalance and isolation. The nurse should speak at a normal volume and tone, and face the client directly.

Choice C reason: This is the correct answer because speaking directly to the client in a normal, clear voice is an appropriate action for the nurse to take. Speaking directly to the client can help them see the nurse's mouth movements and facial expressions, which can enhance understanding and communication. Speaking in a normal, clear voice can help convey the message clearly and respectfully.

Choice D reason: This is incorrect because sitting by the client's side and speaking very slowly is not an appropriate action for the nurse to take. Sitting by the client's side can make it difficult for them to see the nurse's face and hear their voice. Speaking very slowly can also make the message unclear and patronizing. The nurse should sit in front of the client and speak at a normal pace.
