Final answer:
When a dehydrated human patient needs to be given fluids intravenously, they are given intravenous (IV) fluids.
Step-by-step explanation:
When a dehydrated human patient needs to be given fluids intravenously, they are given a solution called intravenous (IV) fluids, which consists of a mixture of water, electrolytes, and sometimes additional nutrients.
IV fluids are administered through a vein using a catheter and can help restore water balance and hydration levels in the body. This can be necessary in cases of severe dehydration, certain medical conditions, or during surgical procedures where a patient is unable to take fluids orally.
