Which risk factor for traumatic brain injury (TBI) should a nurse include in a discussion about prevention for a group of adolescents?
Falls occur more frequently in the younger population.
Females have twice the risk that males do.
Concussions in sports and motor vehicle accidents cause the largest number of TBIs in teens.
Most firearm incidents are accidental.
The Correct Answer is C
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:
A firm toothbrush is not recommended for plaque removal as it can damage the gums and tooth enamel. Soft-bristled toothbrushes are preferred because they are effective at removing plaque while being gentle on the gums and enamel.
Choice b reason:
Brushing more than twice per day does not necessarily irritate the gums unless done with improper technique or with a hard-bristled toothbrush. It is important to brush gently with a soft-bristled toothbrush and to use fluoride toothpaste to maintain oral hygiene and prevent gingivitis.
Choice c reason:
Ensuring that dental restorations such as fillings and crowns fit well is crucial in preventing gingivitis. Poorly fitted restorations can trap food particles and bacteria, leading to plaque buildup and gum inflammation. Regular dental check-ups can help ensure that restorations remain intact and do not contribute to gingivitis.
Choice d reason:
Flossing should not be avoided even if there is bleeding at the gumline. Bleeding can be a sign of gingivitis, and flossing can help remove the plaque and bacteria causing the inflammation. If bleeding persists, it is important to consult a dentist.
Correct Answer is A
Explanation
Choice a reason:
The oral mucosa is the most reliable area to evaluate for central cyanosis in a client with asthma. Central cyanosis reflects a decrease in arterial oxygenation and is best assessed where the blood flow is high and the skin is thin, which is the case with the oral mucosa. It is less likely to be affected by peripheral factors such as temperature and is therefore a more accurate indicator of oxygen saturation in the central circulation.
Choice b reason:
While ear lobes can show signs of cyanosis, they are not the most reliable indicator of central cyanosis because they are more prone to peripheral cyanosis. Peripheral cyanosis can occur in the ear lobes due to local vasoconstriction or decreased blood flow, which may not reflect central oxygenation levels.
Choice c reason:
The soles of the feet are not a reliable indicator of central cyanosis, especially in a client with asthma. The skin on the soles is thicker and has less blood flow compared to the oral mucosa, making it a poor site for assessing central cyanosis. Additionally, the soles can be affected by peripheral factors like pressure and temperature.
Choice d reason:
Conjunctivae are not the most reliable indicator of central cyanosis. While they can show signs of cyanosis, the assessment can be affected by environmental factors and the presence of blood vessels in the conjunctiva that may not accurately reflect central oxygenation levels.
