Final answer:
Ordering a bolus of fluid is time-sensitive and requires physician approval to ensure appropriate administration. It is a large amount of fluid given quickly to replace fluids in the body.
Step-by-step explanation:
When a dehydrated human patient needs to be given fluids intravenously, a bolus of fluid is often administered. A bolus is a large amount of fluid given quickly to rapidly replace fluids in the body. It is typically given through a large-gauge needle or a central line.
The special thing about ordering a bolus of fluid is that it is time-sensitive. It needs to be administered promptly to prevent further dehydration or complications. Delay in administering the bolus can lead to worsening of the patient's condition.
Physician approval is typically required for ordering a bolus of fluid to ensure the appropriate amount and type of fluid is given. However, the two nurse verifications and refrigeration mentioned in the options are not directly related to ordering a bolus of fluid.
