Explanation

The patient's signs and symptoms (pulselessness, coldness, numbness) are critical indicators of acute compartment syndrome, a limb-threatening emergency.
The plaster cast is acting as a constricting device, increasing pressure within the muscle compartment and cutting off blood supply.
The priority action is to relieve the external pressure immediately by removing the cast and simultaneously notifying the physician for further intervention, which may include a fasciotomy.
This combined action addresses the immediate threat to the limb and initiates the necessary medical response to prevent permanent damage.

Option B: Delaying intervention by 15 minutes is dangerous. Pulselessness is a late and ominous sign of compartment syndrome, indicating severe ischemia. Every minute counts to prevent irreversible muscle and nerve death.
Option C: Checking blood pressure in the affected limb does not address the underlying problem, which is localized pressure within the muscle compartment, not systemic hypotension or hypertension. It wastes critical time.
Option D: Elevating the limb is contraindicated. While elevation helps reduce venous swelling, in compartment syndrome it can lower arterial pressure to the limb, further compromising already poor circulation and worsening ischemia.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Priority nursing intervention for acute compartment syndrome in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Recognizing the signs of compartment syndrome is a critical nursing responsibility. Failure to act quickly can lead to limb amputation, permanent disability (like Volkmann's contracture), or rhabdomyolysis with kidney failure.
The nurse is often the first to detect these changes and must have the confidence to act immediately and advocate for the patient by urgently notifying the provider.
What if? If the patient only reported increasing pain not relieved by analgesics and paresthesia (tingling), but still had a palpable pulse? The nurse should still notify the physician immediately as these are the earliest signs of compartment syndrome. The limb should be placed at heart level, and all constrictive dressings loosened while awaiting the physician's assessment and potential pressure measurement.

How to Approach the Question

First, analyze the clinical scenario. The key elements are a fracture, a constricting plaster cast, and acute signs of neurovascular compromise (pulselessness, coldness, numbness).
Recognize these signs as a classic presentation of a medical emergency: acute compartment syndrome.
The question asks for the 'priority' intervention. This means you must select the action that is most critical and time-sensitive to prevent harm.
Evaluate each option based on the pathophysiology of compartment syndrome. The core problem is pressure. Therefore, the priority must be to relieve that pressure.
Option A directly addresses relieving the external pressure (removing the cast) and escalating care (notifying the physician).
Eliminate the other options: Option B is a delay, Option C is irrelevant to the core problem, and Option D is contraindicated and harmful.

Concept Tested & Keywords

Concept Tested: Priority nursing intervention for acute compartment syndrome.
Stem keywords: fracture, plaster cast, pulselessness, coldness, numbness
Lead-in keywords: priority nursing intervention
Clinical cues: The combination of pulselessness, coldness, and numbness in a casted limb are hallmark signs of a severe neurovascular compromise, specifically acute compartment syndrome.
