Final answer:
A PICC line is used to administer long-term chemotherapy and nutrition directly into the bloodstream, suitable for the delivery of these treatments over extended periods.
Step-by-step explanation:
The correct answer to which device is used to administer nutrition or long-term chemotherapy is b. PICC line.
A Peripherally Inserted Central Catheter (PICC line) is a long, flexible tube that is inserted through a vein in the arm and extended to reach a large vein near the heart, allowing for the delivery of medications, nutrients, or treatments directly into the bloodstream over a prolonged period. This is especially useful for long-term chemotherapy treatments and patients who need nutritional support when they cannot consume food orally. The other options provided, such as nasogastric tube, chest tube, and pacemaker, serve different medical purposes and are not suitable for this specific function.
