Rationale 1: The Groshong catheter is used when low flow rates will be infused.
Rationale 2: Groshong catheters are never clamped, because of the design feature that prevents backflow. Pressure from clamping the catheter or extension tubing can force the slit valve to open, allowing a blood leak back into the lumen.
Rationale 3: Heparin flushing is not routinely done with a Groshong catheter because of the design of the catheter tip.
Rationale 4: The client's response to medication should be assessed.
