Final answer:
The nurse should prioritize assessing the client for delayed wound healing due to the essential role of vitamin C in collagen formation and wound repair.
Step-by-step explanation:
The client admitted to the hospital for gallbladder surgery, who is diagnosed with a vitamin C deficiency, should be assessed by the nurse for delayed wound healing postoperatively. Vitamin C is essential for the formation of collagen, which plays a vital role in the healing process. A deficiency in vitamin C can impair the deposition of collagen, leading to weaker capillaries and a propensity to hemorrhage. These factors significantly contribute to poor wound healing outcomes after surgery.
