A nurse is caring for a client following application of a cast. Which of the following actions should the nurse take first?

Rationale: A. Palpate the pulse distal to the cast: Assessing neurovascular status is the priority immediately after cast application. Palpating the distal pulse helps determine adequate circulation and can detect complications like compartment syndrome early, which can lead to permanent damage if untreated. B. Position the casted extremity on a pillow: Elevating the extremity helps reduce swelling and pain, but it is a secondary action. Ensuring perfusion through a pulse check takes precedence before supportive comfort measures are initiated. C. Place an ice pack over the cast: Cold therapy can help minimize swelling and pain in the initial hours after casting, but it should only be done after confirming that circulation is intact. Ice packs should also be used carefully to prevent moisture from damaging the cast. D. Teach the client to keep the cast clean and dry: Education is important for long-term cast care, but it is not the immediate priority after application. Early assessment for circulation, sensation, and movement must occur first to ensure the cast has not compromised perfusion.
