The nurse conducting nursing audits to help increase efficiency and reduce costs should suggest conducting a wound care study to enhance client outcomes instead. By conducting a wound care study, the nurse can identify areas of improvement in wound care practices, which can lead to better patient outcomes and contribute to quality care. This would involve analyzing current practices, implementing evidence-based interventions, and evaluating the impact on patient outcomes.
