During an assessment the nurse performs the action shown in this image. What is the purpose of this action?

A. Measure nerve function in the fingers:

Measuring nerve function typically involves different assessments, such as checking sensation or performing nerve conduction studies. The action in the image is not indicative of a nerve function test.

B. Monitor oxygen status:

Monitoring oxygen status is usually done with a pulse oximeter, which is placed on the finger but does not involve the manual action shown in the image. The image depicts a manual technique, not a pulse oximetry procedure.

C. Determine capillary refill:

The action shown in the image is a technique used to determine capillary refill time. The nurse presses on the nail bed until it blanches and then releases it to see how quickly the color returns. This assesses peripheral perfusion and can indicate circulatory status.

D. Assess finger range of motion:

Assessing finger range of motion involves moving the fingers through their full range of motion, such as flexing, extending, abducting, and adducting them. The action in the image does not reflect these movements and is more indicative of assessing capillary refill.

A) Concussions in sports and motor vehicle accidents cause the largest number of TBIs in teens: Adolescents are particularly susceptible to TBIs due to their frequent involvement in contact sports like football, soccer, and hockey, as well as risky behaviors associated with driving. These activities are leading causes of TBIs in this age group, making education on safety measures and proper use of protective equipment essential in prevention efforts.

B) Females have twice the risk that males do: This statement is incorrect. In reality, males are more likely to sustain TBIs than females, especially in adolescence. The higher risk in males is largely due to their greater participation in high-impact sports and higher likelihood of being involved in motor vehicle accidents.

C) Falls occur more frequently in the younger population: Although falls are a significant cause of TBIs in young children and older adults, they are not the primary cause in adolescents. Teens are more likely to sustain TBIs from sports injuries and car accidents, making these areas more relevant for preventive education.

D) Most firearm incidents are accidental: While firearm-related TBIs can occur, they are not as common in the adolescent population compared to injuries from sports and motor vehicle accidents. Prevention efforts should focus more on the activities that pose the highest risk for this age group.
