What is the most appropriate initial diagnostic study for suspected 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.

The patient should be instructed not to cover the cast with plastic when bathing or swimming, as moisture can weaken the cast and increase the risk of skin irritation and infection. The cast should be kept dry to maintain its structural integrity.

b. Applying heat directly to the cast to speed up drying is not recommended, as excessive heat can lead to discomfort and skin irritation. The cast should be air-dried or gently patted dry with a towel.
c. Using cotton swabs to clean the skin under the cast can introduce fibers into the cast and potentially irritate the skin. The nurse should advise the patient not to insert anything under the cast.
d. Keeping the cast exposed to air for long periods may lead to dirt and debris getting trapped in the cast and increasing the risk of infection. The patient should be cautious and avoid exposing the cast to dirt and contaminants.
