If a factor in raising the productivity of labor is not used in the production process, it is referred to as a reserve for increasing labor productivity. Reserves are classified according to their association with a particular production process, an economic sector, or the national economy.
Definition. 1  Urinary catheterization is the insertion of a catheter into a patient's bladder. The catheter is used as a conduit to drain urine from the bladder into an attached bag or container.
Germs can travel along urinary catheters and cause infections in the bladder that sometimes extends to the kidney. When this happens, it is called a âcatheter-associated urinary tract infection (or âCA-UTIâ). A urinary catheter is a thin tube placed in the bladder to drain urine. Urine drains through the tube into a bag that collects the urine.
