A nurse caring for a client who has a peripheral intravenous saline lock understands that its purpose is to:
Correct Answer: C
Rationale: The correct answer is C: establish a venous route for clients when their condition changes. A saline lock, also known as a heparin lock, is a type of intravenous access device that allows for intermittent access to a vein without the need for a continuous infusion. This is useful for clients whose condition may require medications or fluids intermittently without the need for a continuous IV drip. Option A is incorrect because a saline lock is not specifically designed for highly irritating or hyperosmolar solutions. Option B is incorrect as the primary purpose of a saline lock is not to draw blood for laboratory tests. Option D is incorrect because while a saline lock can be used for short-term IV antibiotic administration, its primary purpose is not for prolonged antibiotic therapy.
