The nurse working in an ophthalmology clinic is preparing to assess a patient's near vision. Which piece of equipment would the nurse use for this assessment?
Ophthalmoscope
Snellen Chart
Magazine
Penlight
The Correct Answer is B
Choice A Reason:
An ophthalmoscope is primarily used for examining the interior structures of the eye, such as the retina, and is not typically used for assessing near vision. It provides a view of the fundus of the eye, which is essential for diagnosing various eye conditions but does not directly assess a patient's reading or close-up vision.
Choice B Reason:
The Snellen Chart is traditionally used to measure distance visual acuity and would not be the first choice for assessing near vision. However, there are versions of the Snellen Chart or similar charts designed for near vision assessment, typically held at a reading distance of about 14 inches from the patient. These charts have rows of letters or symbols that decrease in size and are used to determine the smallest print size a person can read.
Choice C Reason:
A magazine can be a practical tool for assessing near vision informally, as it contains various sizes of print and is a good representation of everyday reading material. The nurse can ask the patient to read a specific paragraph to observe their ability to see and comprehend text at a close distance.
Choice D Reason:
A penlight is not used for assessing near vision. It is typically used to assess the pupillary light reflex or to illuminate specific areas of the eye during an examination. The penlight helps to evaluate the response of the pupils to light but does not measure the patient's ability to read or see objects up close.

Correct Answer is C
Explanation
Choice A Reason:
While falls are a common cause of injury in children, they are not the leading cause of TBI in adolescents. Falls tend to be more frequent in the younger population, particularly in children under the age of 4. In adolescents, sports-related injuries and motor vehicle accidents are more prevalent causes of TBI.
Choice B Reason:
The statement that females have twice the risk of TBI compared to males is incorrect. National data reveal that males are at increased risk of TBI compared to females, especially in the adolescent age group. This is likely due to higher engagement in risk-taking behaviors and contact sports.
Choice C Reason:
Concussions in sports and motor vehicle accidents are indeed the leading causes of TBI in adolescents. Engaging in contact sports such as football, hockey, and soccer can lead to concussions, which are a form of mild TBI. Motor vehicle accidents are also a significant risk factor due to high-impact collisions that can cause head injuries.
Choice D Reason:
Firearm incidents are a serious concern for TBI; however, they are not the most common cause of TBI in adolescents. While firearm-related injuries can be severe and are a leading cause of TBI-related deaths, concussions from sports and motor vehicle accidents account for a larger number of non-fatal TBIs in this age group.
Correct Answer is C
Explanation
Choice a reason:
Rhonchi are coarse, rattling respiratory sounds somewhat like snoring, usually caused by obstruction or secretion in the larger airways. They are not considered normal breath sounds and are typically heard in conditions such as chronic bronchitis.
Choice b reason:
Crackles are the sounds you will hear in a lung field that has fluid in the small airways. These sounds are commonly heard in patients with pneumonia, heart failure, and restrictive pulmonary diseases. They are not normal breath sounds.
Choice c reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. In a healthy individual, these sounds are expected to be heard in the 1st and 2nd intercostal spaces near the sternal body.
Choice d reason:
Tracheal breath sounds are harsh, high-pitched sounds heard when auscultating over the trachea in the neck. They are not normally heard over the intercostal spaces of the chest wall.
