Final answer:
Care for Mr. Jones's central line includes using aseptic technique and flushing the line with saline. Dressings should be changed regularly, and cold compresses are not a standard part of care unless specific issues arise.
Step-by-step explanation:
Nurse Allyson's care plan for Mr. Jones's central line should certainly include using aseptic technique to prevent infection, which is critical when handling central lines. Flushing the line with saline is a routine procedure to ensure the line remains patent and to prevent blockages. Changing the dressing regularly is also important, although the frequency can vary based on the facility's protocol and the patient's condition; a weekly change might be appropriate, but some situations may require more frequent changes. Applying cold compresses is generally not a routine part of central line care unless there is specific swelling or irritation that needs to be addressed, which should be evaluated on a case-by-case basis.
