A nurse is caring for a client with a hip fracture. The client is scheduled for surgery. When performing an ORIF procedure of a hip. what is the purpose of the internal fixation?
To fix bone fragments together using plates, screws, or other devices.
To remove damaged cartilage and bone from the affected area.
To repair damaged ligaments and tendons in the affected area.
To stabilize the fractured bone externally using a cast or splint.
The Correct Answer is A
A. To fix bone fragments together using plates, screws, or other devices. This is the correct purpose of open reduction and internal fixation (ORIF). It stabilizes the bone fragments to ensure proper alignment and healing.
B. To remove damaged cartilage and bone from the affected area. This describes a debridement procedure, not ORIF. ORIF focuses on stabilizing the fracture, not removing tissue.
C. To repair damaged ligaments and tendons in the affected area. While ligament and tendon repair can be part of some orthopedic surgeries, ORIF specifically aims to fix bone fragments together.
D. To stabilize the fractured bone externally using a cast or splint. This describes external fixation or immobilization methods, not internal fixation.

Correct Answer is B
Explanation
A. Hypovolemic shock: While disorientation and low SaO2 could be signs of hypovolemic shock, the presence of petechiae is not a typical symptom. Hypovolemic shock is usually associated with blood loss and does not present with petechiae.
B. Fat embolism: Fat embolism syndrome (FES) is a common complication after fractures, especially long bones like the tibia. The classic triad includes respiratory distress, neurological symptoms, and petechiae, making this the most likely diagnosis.
C. Thrombophlebitis: Thrombophlebitis involves inflammation of a vein due to a blood clot, typically presenting with localized pain, swelling, and redness, not petechiae or disorientation.
D. Osteomyelitis: Osteomyelitis is an infection of the bone. Symptoms include pain, fever, and redness over the infected area, but it does not typically present with disorientation, low SaO2, or petechiae.
Correct Answer is B
Explanation
A. Cough: Cough is not a common symptom of osteomyelitis. It is more commonly associated with respiratory infections or conditions affecting the lungs and airways.
B. Fever: Fever is a common symptom of osteomyelitis, which is an infection of the bone. The body’s immune response to the infection often results in an elevated body temperature.
C. Rash: Rash is not typically associated with osteomyelitis. Rashes are more commonly seen in skin conditions, allergic reactions, or certain systemic infections.
D. Headache: Headache is not a common symptom of osteomyelitis. It is more frequently associated with conditions affecting the head, such as migraines, tension headaches, or infections of the central nervous system.
