A nurse is providing discharge education to a client who has a double-lumen peripherally inserted central catheter (PICC). The client will be receiving IV antibiotics at home with a caregiver’s assistance. Which statement by the caregiver indicates learning has been effective?

Choice A reason: Caregivers should never attempt to reinsert a PICC line if it becomes dislodged. Reinsertion requires sterile technique and trained personnel due to the risk of infection, air embolism, and vessel injury. This statement indicates incorrect and unsafe understanding of PICC care. Choice B reason: While flushing with normal saline is correct, the volume and frequency depend on institutional policy and the type of catheter. Additionally, this statement addresses only one lumen and does not demonstrate full understanding of double-lumen PICC maintenance. Choice C reason: Both lumens of a double-lumen PICC must be flushed routinely, even if only one lumen is used. This prevents clot formation, catheter occlusion, and infection. This statement reflects accurate understanding of PICC maintenance and indicates effective learning. Choice D reason: PICC dressings are typically changed every 7 days or sooner if they become loose, damp, or soiled. Waiting 8–10 days increases the risk of infection. This statement demonstrates incorrect knowledge regarding dressing change frequency.
