Final answer:
When a high venous alarm sounds, the staff member should look from the top of the central venous catheter through the end of the intravenous line to identify any issues.
Step-by-step explanation:
When a high venous alarm sounds, the staff member should look from the top of the central venous catheter through the end of the intravenous line.
For example, if a patient has a central venous catheter inserted in their subclavian vein and an intravenous line running from the catheter to their IV site, the staff member should visually inspect the entire length of these two components.
This visual inspection is important to identify any kinks, disconnections, or other issues that may be causing the high venous alarm to sound.
