Answer to Question 1
ANS: C
Fat emboli are of greatest concern in individuals with fractures of the long bones. Fat droplets from the marrow are transferred to the general circulation, where they are transported to the lung or brain. This type of embolism usually occurs within the second 12 hours after the injury. Sepsis would manifest with fever and lethargy. Osteomyelitis usually is seen with pain at the site of infection and fever. A child with an acute respiratory tract infection would have nasal congestion, not chest pain.
Answer to Question 2
ANS: D
Injuries occur when the adolescent's body is not suited to the sport or when he or she lacks the insight and judgment to recognize that an activity exceeds his or her physical abilities. More injuries occur when an adolescent's muscles and body systems (respiratory and cardiovascular) are not conditioned to endure physical stress. Injuries do not occur from fatigue but rather from overuse. All sports have the potential for injury to the participant, whether the youngster engages in serious competition or in sports for recreation. More injuries occur during recreational sports than during organized athletic competition.
