Final answer:
Proper catheter insertion and maintenance require sterile technique, regular hand hygiene, and perineal care to prevent infections.
Step-by-step explanation:
Proper catheter insertion and maintenance require sterile technique to prevent infections. It is not an unnecessary procedure, as catheters are often necessary for patients requiring long-term medication or fluid administration. Catheter insertion and maintenance are not limited to male patients; both males and females may require catheterization. Regular hand hygiene is crucial to prevent contamination during the procedure, and regular perineal care is essential to maintain cleanliness and prevent infections.
