Final answer:
After cast application, monitoring for compartment syndrome, a condition where increased pressure leads to insufficient blood supply within a body compartment, is true and essential.
Step-by-step explanation:
After cast application, compartment syndrome is a primary concern that requires education and monitoring. The answer to the student's question is A) True. Compartment syndrome occurs when increased pressure within one of the body's anatomical compartments results in insufficient blood supply to tissue within that space. This can happen after the application of a rigid cast, as swelling within the tight confines of a cast can lead to dangerously high pressures. It is critical for healthcare providers to educate patients about the signs and symptoms of compartment syndrome, which may include severe pain, sensory deficits, and diminished pulse below the affected area. Monitoring for these symptoms is vital, as compartment syndrome is a medical emergency that can lead to permanent tissue damage or even loss of limb if not promptly addressed.
