Final answer:
Anti-embolic stockings are applied for the prevention of deep vein thrombosis (DVT), which is the formation of blood clots in deep veins that can lead to serious complications like pulmonary embolism (PE).
Step-by-step explanation:
The patient care technician (PCT) should recognize that the application of anti-embolic stockings each morning is performed for the prevention of deep vein thrombosis (DVT). DVT refers to the formation of a blood clot in a deep vein, typically in the legs, which can have serious consequences if the clot dislodges and travels to the lungs, leading to pulmonary embolism (PE). PE can disrupt pulmonary circulation and may cause lung damage or death. Anti-embolic stockings help by providing graduated compression, which prevents the accumulation of blood in the legs and swelling, reduces the risk of clot formation, and assists in maintaining venous return to the heart, especially in patients at risk, such as those with chronic conditions, or during periods of prolonged immobility, such as long-haul flights.
