What is the first action a nurse should take after applying a cast?

After applying a cast, the priority action for the nurse is to palpate the pulse distal to the cast. This step is critical for assessing circulation to the affected limb and ensuring that blood flow is adequate. The cast can exert pressure on the underlying tissues, which may compromise circulation, leading to potential complications such as compartment syndrome. By checking the distal pulse, the nurse can detect any signs of vascular impairment early on, allowing for timely intervention if necessary.

Ensuring perfusion is fundamental in a clinical setting, especially after a cast placement when swelling can occur. While monitoring for other signs, such as capillary refill or educating the patient about cast care, is also important, assessing the pulse is the most immediate action to verify that the cast has not hindered blood circulation. This prioritization aligns with the principles of the nursing process, where assessment takes precedence in ensuring patient safety.
