A nurse is evaluating an assistive personnel's (AP) use of materials while providing client care. Which of the following actions by the AP demonstrates cost-effective use of resources?

A. Wearing sterile gloves when collecting a urine specimen from an indwelling urinary catheter: Sterile gloves are not required for routine urine specimen collection from an indwelling catheter unless the procedure involves breaking the closed system for insertion or manipulation. Using sterile gloves unnecessarily increases supply costs without improving safety. B. Donning an N95 mask before caring for a client who is on contact precautions: Contact precautions require gloves and a gown, not an N95 respirator. Using an N95 inappropriately consumes a more expensive resource without providing additional protection, which is not cost-effective. Appropriate PPE selection should be based on transmission precautions. C. Returning unopened supplies to the storage room: Returning unopened supplies for future use prevents unnecessary waste and reduces institutional costs. Supplies that remain sterile and intact can be reused for other clients, demonstrating effective resource management while maintaining safety standards. D. Replacing a continuous feeding administration set every 8 hr: Standard guidelines recommend replacing continuous enteral feeding sets every 24 hours to prevent infection, unless otherwise indicated. Replacing them every 8 hours unnecessarily increases supply use and cost without additional safety benefit, making it a less cost-effective practice.
