Final answer:
The TKVO/maintenance infusion volume for patients 12 years and older refers to the amount of fluid administered to maintain hydration while not receiving any specific treatments or medications.
Step-by-step explanation:
The TKVO/maintenance infusion volume for patients 12 years and older refers to the amount of fluid that is administered to patients to maintain hydration and prevent dehydration while they are not receiving any other specific treatments or medications.
The acronym TKVO stands for 'To Keep Vein Open' and it represents the rate at which the fluid is infused into the patient's vein. The maintenance infusion volume varies depending on factors such as the patient's weight, medical condition, and if they are nil per os (NPO), which means they are not allowed to take anything by mouth.
For example, a commonly used maintenance infusion rate is 75-125 mL per hour for an adult patient. However, it is important to note that the specific maintenance infusion volume should be determined by a healthcare professional based on the individual patient's needs and medical condition.
