Which complication could occur if the intravenous catheter is not monitored for patency?

Monitoring the intravenous catheter for patency is crucial in preventing complications that can arise during IV therapy. If a catheter is not regularly checked for patency, one significant risk is the formation of clots within the catheter. Clotting can occur when blood or particulate matter obstructs the flow within the catheter, potentially causing blockage. This can hinder the delivery of fluids and medications, leading to inadequate patient treatment and necessitating the replacement of the catheter.

Furthermore, when a catheter is occluded due to clot formation, it may also lead to inflammation and irritation of the vein, which could cause further complications such as thrombophlebitis. Ensuring that the catheter remains patent allows for continuous and efficient administration of IV fluids and medications, which is essential for effective patient care.

While fluid overload, electrolyte imbalances, and infections are relevant concerns in IV therapy, they don't directly stem from issues related to the patency of the catheter. Monitoring for patency is specifically intended to mitigate the risk of clotting and subsequent related complications.
