The nurse knows that an advantage of using a central venous access device is that:
Correct answer
D
Rationale
The correct answer is D: fluids & medications that may be irritating to peripheral veins can be given. Central venous access devices allow for administration of fluids and medications that could cause irritation or damage to peripheral veins, as the larger central veins can handle higher osmolarity and pH levels without causing phlebitis. This advantage is crucial in patients requiring long-term or aggressive treatments.
- A is incorrect because central lines actually have a higher risk of sepsis due to their longer dwell time and proximity to major blood vessels.
- B is incorrect because while patency can be confirmed with a saline flush in central lines, it can also be done in peripheral IV catheters.
- C is incorrect because both central and peripheral lines require aseptic technique for placement to prevent infection.
