Final answer:
The nurse manager used a problem-focused trigger to address the increase in catheter-associated UTIs, which occurs when a specific clinical issue prompts action to find a solution.
Step-by-step explanation:
The nurse manager used a problem-focused trigger to address the recent increase in catheter-associated urinary tract infections (UTIs) on the unit. A problem-focused approach is taken when a professional identifies a clinical issue or problem in practice and uses evidence-based practice to find a solution. In this case, the increase in UTIs is the problem that has prompted the nurse manager to take action. Potential ways that bacteria could have been introduced to a patient's urinary tract during surgery include improper sterile technique, contaminated surgical instruments, or the introduction of bacteria via a urinary catheter.
