What type of injuries can occur in the lower extremity?

The correct answer identifies that fractures and sprains are indeed common types of injuries that can occur in the lower extremity.

Fractures can involve any bone in the lower limb, including the femur, tibia, fibula, or bones in the foot and ankle. These injuries often happen due to falls, direct impacts, or high-stress activities.

Sprains, on the other hand, occur when ligaments that connect bones at a joint are stretched or torn. The ankle is particularly susceptible to sprains, which can happen during activities that require jumping, running, or uneven footing.

This answer effectively encompasses a broad range of possible injuries that affect the lower extremities, highlighting the significance of recognizing these common injuries in a first aid or emergency situations. Understanding these types of injuries aids in providing appropriate care and referral to a medical professional when necessary.
