Final answer:
During the evaluating stage, the nurse validates the problem with the client and collects data on catheter-associated infections on the nursing unit.
Step-by-step explanation:
In the evaluating stage, the nurse performs several activities to assess the effectiveness of the care provided. Two activities that the nurse performs during this stage are:
- Validates with the client the problem of constipation: This involves discussing the issue with the client and confirming their experience of constipation.
- Collects data to determine the number of catheter-associated infections on the nursing unit: This involves gathering information and statistics on the incidence of infections related to catheter use on the nursing unit.
Additionally, the nurse does not perform the activities listed in options C, D, and E during the evaluating stage.
