Final answer:
The Five Ps of fractures and compartment syndrome are Pain, Pulse, Pallor, Paresthesia, and Paralysis, which are critical diagnostic signs for evaluating the severity and presence of these conditions.
Step-by-step explanation:
The Five Ps of fractures and compartment syndrome are A. Pain, Pulse, Pallor, Paresthesia, and Paralysis. These are the signs and symptoms that medical professionals look for when assessing a patient for a fracture or the development of compartment syndrome, which is a severe complication where increased pressure within a closed muscle compartment compromises the circulation and function of the tissues within that space. Pain is typically the first and most apparent symptom, while changes in Pulse and Pallor (pale appearance due to lack of blood flow) might indicate a more severe issue, such as compromised blood flow. Paresthesia (tingling or numbness) and Paralysis (loss of muscle function) can occur if nerve compression or damage is present.
