Final answer:
A venous catheter can be used for a patient requiring frequent or regular IV injections. It provides reliable access without the need for multiple needle sticks and reduces the risk of bloodstream infections.
Step-by-step explanation:
The venous device that can be used for a patient requiring IV injection at frequent or regular intervals is called a "venous catheter." Venous catheters are commonly used for long-term administration of medication or fluids. They are inserted into a vein, usually in the arm or chest, and provide reliable access for repeated injections without the need for multiple needle sticks. Venous catheters can be left in place for extended periods, and they reduce the risk of bloodstream infections compared to repeated needle insertions.
