Which intervention is important for preventing complications in a patient with a lower extremity fracture?

Adolescents, especially those involved in high-impact sports or activities, are at a higher risk of stress fractures due to their bones still growing and being more susceptible to repetitive stress injuries.

b. Young adults: Young adults may also be at risk of stress fractures, but adolescents are more vulnerable due to their ongoing bone growth and development.
c. Older adults: While older adults are at risk of fractures, stress fractures are more commonly seen in younger individuals engaged in high-impact activities.
d. Middle-aged adults: Middle-aged adults may experience fractures related to osteoporosis, trauma, or other factors, but they are not the primary population at risk for stress fractures.

Patients with external fixation require close monitoring of the pin sites for signs of infection, as they are at risk of developing pin site infections.

a. Providing passive range of motion exercises: Passive range of motion exercises may be appropriate in some cases, but they are not specific to external fixation management.
b. Changing the dressing daily: Dressing changes for external fixation are typically done as instructed by the healthcare provider, which may not necessarily be daily.
c. Loosening the fixation screws every 4 hours: Fixation screws should not be loosened without proper medical guidance, as this can compromise the stability of the external fixation device.
