Which risk factor for traumatic brain injury (TBI) should a nurse include in a discussion about prevention for a group of adolescents?

Choice a reason:
Draping body areas that are not being assessed is important for maintaining the client's privacy and comfort, but it is not the highest priority when dealing with a client with generalized muscle weakness. The primary concern is to prevent further strain or injury during the examination.

Choice b reason:
Limiting position changes as much as possible is the priority when examining a client with generalized muscle weakness. Frequent or unnecessary movements can cause fatigue, discomfort, and may even be unsafe if the client has severely compromised muscle strength. The nurse should plan the examination to minimize the number of times the client needs to change positions.

Choice c reason:
Hand-washing throughout the exam is a standard practice to prevent the spread of infection. While it is crucial for both the client's and the nurse's safety, in the context of a client with generalized muscle weakness, the priority is to conduct the exam in a way that does not exacerbate the client's condition.

Choice d reason:
Using alcohol swabs to clean the stethoscope before and after the exam is also a standard infection control practice. However, it is not the most immediate concern when prioritizing the steps of a physical examination for a client with muscle weakness.

Choice A reason:
Peripheral vision is the ability to see objects and movement outside of the direct line of vision. This type of vision is assessed using different methods, such as confrontation visual field testing, where the examiner moves objects into the patient's side vision from different angles. Standing 20 feet away from a chart would not be the appropriate method to assess peripheral vision.
Choice B reason:
The assessment of external eye structures involves examining the physical appearance and condition of the eyelids, sclera, conjunctiva, and surrounding areas. This is typically done at a close range and does not require the patient to stand at a distance from a chart. The nurse would inspect these structures directly, often with the aid of a penlight for better visibility.

Choice C reason:
Distant vision is the ability to see objects far away, and it is what the nurse is preparing to assess when the client is asked to stand 20 feet from a chart. This distance is standard for the Snellen eye chart, which is used to measure visual acuity. The chart has rows of letters that decrease in size, and the patient is asked to read the smallest line of letters they can see clearly. The Snellen chart is the most common method used by eye doctors to measure visual acuity.
Choice D reason:
Near vision is the ability to see objects that are close to the eyes clearly. It is assessed using different charts, such as the Jaeger eye chart, which contains blocks of text in various type sizes. The patient is asked to read the text at a close range, typically around 14 inches, not 20 feet. Therefore, standing 20 feet away from a chart would not be the method to assess near vision.
