Explanation

A "hotspot" is a specific term for a localized area on a cast that feels warmer than the surrounding areas.
This warmth is a cardinal sign of inflammation, which is the body's response to an underlying infection or pressure-induced tissue injury (pressure ulcer).
Increased blood flow and metabolic activity at the site of the problem generate heat, which radiates through the cast material.
The presence of a hotspot, sometimes accompanied by a foul odor or drainage, requires prompt reporting and investigation.

Option B: Tightness of a cast is a primary cause of compartment syndrome, but its signs are different. The key indicators are the '6 Ps': severe Pain, Pallor (paleness), Paresthesia (numbness/tingling), Pulselessness, Paralysis, and Poikilothermia (coolness), not localized warmth.
Option C: Poor perfusion (impaired blood flow) would result in the extremity becoming cool, pale, or cyanotic (bluish), with a delayed capillary refill. This is the opposite of a 'hotspot,' which is characterized by warmth.
Option D: Limited movement is the intended purpose of a cast—to immobilize the fracture for healing. An inability to move the digits (paralysis) is a very late and ominous sign of compartment syndrome, not associated with a hotspot.

Clinical Relevance

Nursing practice connection: Use the key finding related to Complications of Cast Immobilization to guide bedside assessment, documentation, and the next nursing action.
Regular assessment for hotspots is a critical nursing intervention in cast care to detect infection or pressure ulcers early.
Promptly identifying and reporting a hotspot can prevent the progression of infection to osteomyelitis (bone infection) or the worsening of a pressure ulcer, which can lead to significant tissue loss.
Patient education is vital. Patients and families should be taught to feel the cast for hotspots, check for foul odors, and report these findings immediately.

How to Approach the Question

First, identify the key clinical sign presented in the question, which is 'hotspots' on a leg cast.
Recall the common complications associated with orthopedic casts, such as infection, pressure ulcers, and compartment syndrome.
Connect the specific sign ('hotspot,' meaning localized warmth) to its underlying pathophysiology. Heat is a cardinal sign of inflammation.
Evaluate the options based on this connection. 'Sign of infection' is directly related to inflammation and heat.
Systematically eliminate the other options by recalling their characteristic signs. Tightness and poor perfusion are associated with coolness and pallor (the opposite of heat). Limited movement is either expected or a sign of nerve damage, not a thermal sign.
