CNJNE IVE Adult IV therapy Practice Test

Utilizing the other ports of a triple lumen catheter while one lumen is occluded is not a recommended practice because it could lead to further complications. When one lumen is occluded, there are potential factors causing the blockage, which may relate to the integrity and function of the entire catheter. By using the other lumens, there's a risk of increasing pressure in the system, which may exacerbate the occlusion or lead to backflow issues that could affect the overall functionality of the catheter.

Furthermore, using an occluded lumen or putting additional stress on the remaining lumens without resolving the obstruction status of the affected lumen could lead to accidental catheter fractures or other mechanical failures. These complications could result in severe consequences for patient safety, including the potential for infiltration or infection.

Maintaining the integrity and proper function of all lumens in a triple lumen catheter is essential for effective IV therapy, and addressing any occlusion directly is always the most prudent course of action.
