Final answer:
The primary danger related to a broken catheter tip is an embolus. An embolus can travel through the bloodstream and potentially block a vessel critical to a major organ, leading to serious consequences such as a heart attack, stroke, or pulmonary embolism.
Step-by-step explanation:
The primary danger related to a broken catheter tip is an embolus. When a portion of a thrombus (a blood clot) breaks free from the vessel wall and enters the circulation, it is referred to as an embolus. An embolus can travel through the bloodstream and potentially block a vessel critical to a major organ, leading to serious consequences such as a heart attack, stroke, or pulmonary embolism.
