Explanation

The highest priority is to assess the neurovascular status of the limb distal to the injury to prevent permanent damage.
Assessing the color of the hand is a key component of evaluating circulation (perfusion).
Changes in color, such as pallor (paleness) or cyanosis (bluish tint), are early indicators of compromised blood flow, which could signal developing compartment syndrome.
This assessment is rapid, non-invasive, and provides immediate information about the potential for a limb-threatening complication.

Option A: Assessing the patient's overall mobilization is important for preventing complications of immobility, but it is not the immediate priority after applying a hand cast. A threat to the limb's viability takes precedence.
Option B: Assessing the systemic pulse rate (e.g., at the radial artery of the unaffected arm or the carotid artery) reflects the patient's overall cardiovascular status, not the specific circulatory status of the casted hand.
Option C: A fractured hand and cast do not directly impact a patient's ability to walk. This assessment is irrelevant to the clinical situation.

Clinical Relevance

Nursing practice connection: Use the key finding related to Priority nursing assessment for a patient with a limb cast to guide bedside assessment, documentation, and the next nursing action.
Nurses must perform and document neurovascular checks frequently (e.g., every 1-2 hours) in the initial 24-48 hours after a cast is applied, as this is the period of greatest risk for swelling.
Any abnormal neurovascular finding (e.g., pale or blue fingers, delayed capillary refill, increased pain, numbness) is a potential emergency and must be reported to the healthcare provider immediately. Delay can lead to irreversible muscle and nerve damage or loss of the limb.
What if? If the patient reported severe, unrelenting pain that is not relieved by pain medication, this would become the highest priority finding to assess and report, even over color changes, as it is the cardinal sign of compartment syndrome.

How to Approach the Question

First, identify that the question is asking for a priority action ('perform first'). This signals that you must differentiate between several potentially correct nursing actions and choose the most critical one.
Analyze the clinical scenario: a patient with a new plaster cast. The primary risk associated with a circumferential cast is swelling, which can lead to impaired circulation and nerve function (neurovascular compromise).
Evaluate the options in the context of this primary risk. The best answer will be the one that directly assesses for neurovascular compromise.
Option A (mobilization) and C (walking) are related to general mobility and are not specific to the immediate safety of the fractured hand.
Option B (pulse rate) assesses systemic circulation, not the localized circulation in the affected limb.
Option D (color of the hand) is a direct assessment of perfusion to the area distal to the cast and is a key part of a neurovascular check. Therefore, it is the highest priority.

Concept Tested & Keywords

Concept Tested: Priority nursing assessment for a patient with a limb cast.
Stem keywords: plaster cast, fractured hand, nurse perform first
Lead-in keywords: first
Clinical cues: The presence of a plaster cast is a clinical cue for the risk of swelling and neurovascular compromise.
