Final answer:
When administering mannitol for increased intracranial pressure, supplies required include the mannitol IV solution, IV infusion set, filter, intravenous catheter, alcohol wipes, gloves, an IV pole, and potentially an infusion pump.
Step-by-step explanation:
When administering mannitol to a client with increased intracranial pressure, a nurse would need several supplies to ensure proper and safe administration of this medication. These supplies include a prescribed mannitol IV solution, an IV infusion set, a filter (as mannitol solutions may crystallize), a suitable intravenous (IV) catheter, alcohol wipes for asepsis, gloves for infection control, an IV pole, and potentially an infusion pump to regulate the flow rate. It is critical to follow the physician's orders for dosage and administration parameters while monitoring the patient for any adverse reactions.
