Final answer:
The insertion of an indwelling catheter in a client with obstruction and retention should be done by an experienced RN. Measuring output and obtaining a specimen are outside the scope of practice for UAPs. The UAP's knowledge of sterile technique or catheter insertion is not the main issue.
Step-by-step explanation:
The insertion of an indwelling catheter in a client with obstruction and retention should be done by an experienced Registered Nurse (RN). This is because clients with these conditions are usually difficult to catheterize, and the nurse needs to evaluate the pain response during the procedure.
Measuring output and obtaining a specimen are outside the scope of practice for the Unlicensed Assistive Personnel (UAP). The primary role of a UAP is to provide basic care and support under the supervision of a licensed nurse.
While the UAP's knowledge of sterile technique and catheter insertion may not be the main issue, in this case, the complexity and potential complications involved require an experienced RN to perform the procedure.
