The nurse is caring for a patient with a fracture who has a Buck's traction boot in place. The boot helps decrease which condition?
Post-traumatic arthritis
Intra-articular adhesions
Extra-articular adhesions
Muscle spasm
The Correct Answer is D
A. Post-traumatic arthritis can develop after a fracture, but Buck's traction does not directly prevent or treat arthritis. Post-traumatic arthritis is a long-term complication that is managed through other interventions such as physical therapy or joint replacement if necessary.
B. Intra-articular adhesions refer to scar tissue formation inside the joint, which is not the primary focus of Buck's traction. Buck's traction is used to immobilize the limb and reduce muscle spasm, not to address intra-articular issues.
C. Extra-articular adhesions involve the formation of scar tissue outside the joint and are not specifically targeted by Buck's traction. The primary goal of the boot is to reduce muscle spasm and maintain alignment.
D. Muscle spasm is the primary condition that Buck's traction helps decrease. The boot applies a gentle, continuous pull on the limb, which helps to alleviate muscle spasms, reduce pain, and maintain proper alignment while the fracture heals.

Correct Answer is B
Explanation
A. Bone demineralization occurs over a longer period of immobilization and is not a primary concern within the first 24 to 48 hours following a fracture.
B. Fat embolism syndrome (FES) is a serious complication that can occur within 24 to 48 hours after a long bone fracture, especially a femur fracture. Fat droplets from the bone marrow can enter the bloodstream, leading to embolism in the lungs, brain, or heart, causing symptoms such as respiratory distress, confusion, and petechial rash.
C. Muscle atrophy is a concern with prolonged immobility, but it develops over a longer period of time, not within the first 24 to 48 hours after a fracture.
D. Renal calculi (kidney stones) are more commonly associated with long-term immobility or dehydration, not an immediate complication following a fracture.
Correct Answer is B
Explanation
A. Obtaining a blood sample is important for diagnosing a myocardial infarction, but it is not the immediate priority. The nurse should first focus on stabilizing the patient before performing diagnostic tests.
B. Initiating oxygen therapy is the priority action. Oxygen is critical in improving oxygenation and reducing myocardial stress during a myocardial infarction. It helps prevent further damage to the heart muscle and supports overall cardiac function.
C. Inserting the IV catheter is important for administering medications and fluids, but it is not as urgent as providing oxygen therapy, which directly impacts the client's oxygenation and cardiac function.
D. Attaching the leads for a 12-lead ECG is essential for diagnosing a myocardial infarction, but the priority is to stabilize the patient by administering oxygen before performing diagnostic tests.
