What is the most appropriate initial diagnostic study for suspected fractures?
X-ray
MRI
CT scan
Ultrasound
The Correct Answer is A
X-ray is the most appropriate initial diagnostic study for suspected fractures. It provides clear images of bones and can help identify the presence, location, and extent of the fracture.
b. MRI: MRI is useful for soft tissue imaging, but it may not be the first choice for initial evaluation of fractures. X-rays are more commonly used for immediate assessment.
c. CT scan: CT scan can provide detailed images of bones and soft tissues, but it is not typically the first-line imaging study for fractures. X-rays are more commonly performed first.
d. Ultrasound: Ultrasound is primarily used for imaging soft tissues and may not provide sufficient detail for evaluating fractures. X-rays are more appropriate for initial assessment.

a. Performing passive range of motion exercises regularly is important for preventing joint stiffness and muscle atrophy but may not directly prevent skin breakdown and pressure ulcers.
b. Applying petroleum jelly to the skin under the immobilization device is not recommended, as it can cause skin maceration and compromise the device's fit and function.
d. Providing a soft foam mattress overlay can enhance patient comfort but may not be sufficient to prevent skin breakdown and pressure ulcers in patients with prolonged immobilization.

a. Severe pain and visible deformity: Severe pain and visible deformity are more commonly seen in acute fractures resulting from trauma or high-impact injuries, not stress fractures.
b. Sudden onset of swelling and bruising: Sudden onset of swelling and bruising is more indicative of acute fractures, not stress fractures.
d. Inability to bear weight on the affected limb: Inability to bear weight may be present in some fractures, but it is not a specific characteristic of stress fractures.
