Final answer:
The Bair Hugger machine would be sent as a patient-cooling device. An Intravenous infusion pump is used for adminstering fluids intravenously to a dehydrated patient. And sterilization is necessary for medical items in contact with bodily tissues or fluids.
Step-by-step explanation:
The unit that is called for a patient-cooling machine is the Bair Hugger. This device is specifically designed for temperature management in clinical settings and can provide cooling to patients who need it. You should not send a Nebulizer, Sequential compression device, Pulse oximeter, or an Intravenous infusion pump, as none of these machines is designed for patient cooling.
When a dehydrated human patient needs to be given fluids intravenously, an Intravenous infusion pump is typically used. This machine allows for the precise delivery of fluids, medications, or nutrients directly into the patient's bloodstream.
Sterilization is required for various types of medical items to ensure patient safety and to prevent infections. Materials that come into contact with bodily tissues or fluids would be among those that should be sterilized.
