Final answer:
A patient with a bone protruding through the skin has a Compound fracture, which is a serious condition that requires immediate medical attention. The correct answer is A) Compound fracture.
Step-by-step explanation:
When a patient arrives with the end of the bone protruding through the skin, it indicates that the patient has a Compound fracture, also known as an open fracture. This type of fracture is serious because the bone has not only broken, but it has also broken through the soft tissues and skin, which increases the risk of infection and requires emergency medical treatment.
Unlike a closed fracture, where the bone is broken but does not pierce the skin, an open fracture involves visible bone and is more complex to treat due to the potential for contamination and the involvement of soft tissue damage. Therefore, the correct answer is A) Compound fracture.
