The nurse educator asks the student nurse to explain the most common causes of blindness in the United States. Which of the following options will the student nurse select as one of the top causes of blindness?

Choice A reason: This is incorrect because administering IV ketorolac is not a priority intervention for a client with cholecystitis. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal bleeding and kidney damage, which are contraindicated in cholecystitis. The nurse should administer analgesics as prescribed, but only after assessing the pain level and severity.

Choice B reason: This is incorrect because reporting findings to healthcare provider is not a priority intervention for a client with cholecystitis. The nurse should communicate with the healthcare provider about the client's condition and treatment plan, but only after assessing the pain level and other vital signs.

Choice C reason: This is incorrect because offering a high-calorie, high-fat meal is not an intervention for a client with cholecystitis, but a potential trigger. High-fat foods can stimulate the gallbladder to contract and cause more pain and inflammation. The nurse should advise the client to avoid fatty foods and follow a low-fat diet.

Choice D reason: This is the correct answer because assessing the pain level is a priority intervention for a client with cholecystitis. Pain is the most common symptom of cholecystitis and can indicate the severity and complications of the condition. The nurse should assess the pain level using a numeric or descriptive scale, and monitor for changes in location, intensity, and duration.

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.
