Final answer:
Proper hydration before contrast administration is important to prevent dehydration, maintain blood volume, and minimize the risk of side effects.
Step-by-step explanation:
Proper hydration before contrast administration is particularly important because it helps to prevent dehydration and maintain blood volume. Contrast agents used in medical imaging procedures can put stress on the kidneys, and being well hydrated helps the kidneys to function optimally in filtering and eliminating the contrast agent from the body. Additionally, proper hydration can help minimize the risk of side effects associated with contrast administration, such as allergic reactions or kidney damage.
