What eye function is the nurse preparing to assess when the client is asked to stand 20 feet from a specific chart that is mounted on the examination room wall?
Peripheral vision.
External eye structures.
Distant vision.
Near vision.
The Correct Answer is C
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.

Correct Answer is ["A","B","C","D"]
Explanation
Choice a reason:
Wearing nonslip shoes in the house can prevent falls, which are a common cause of traumatic brain injuries (TBIs) in adolescents. Falls often occur due to slippery surfaces, and nonslip shoes provide better traction, reducing the risk of such accidents.
Choice b reason:
Supervised use of guns by an adult is crucial to prevent accidental shootings, which can result in TBIs or even more severe outcomes. Adolescents may not fully understand the risks associated with handling firearms, and adult supervision ensures that safety measures are followed.
Choice c reason:
The consistent use of seat belts in vehicles is one of the most effective ways to prevent TBIs during car accidents. Seat belts keep occupants from being ejected or hitting the interior of the car, significantly reducing the risk of head injuries.
Choice d reason:
Avoiding risky activities such as snowboarding without proper safety measures can prevent sports-related TBIs. While snowboarding, wearing a helmet and other protective gear is essential to protect the head during falls or collisions.
Correct Answer is C
Explanation
Choice A Reason:
The dorsal aspect of the hand, rather than the finger pads, is more sensitive to temperature due to its thinner skin. Therefore, while the finger pads can detect temperature, they are not the best tool for this purpose.
Choice B Reason:
Vibrations, such as those produced by vocal fremitus, are typically assessed using the ulnar edge or the palmar aspect of the hand, not the finger pads. The finger pads are sensitive but do not provide the best surface for detecting vibrations.
Choice C Reason:
The finger pads are densely innervated and are the most sensitive part of the hand, making them ideal for palpating pulses. Pulses are subtle and require a fine touch to assess properly, which is why the finger pads are the preferred area for this assessment.
Choice D Reason:
Fremitus refers to the palpable vibrations transmitted through the bronchopulmonary tree to the chest wall as someone speaks. It is best felt with the ball of the hand or the ulnar edge, not the finger pads.
