Final answer:
During pregnancy and the immediate puerperium, clotting factors and fibrinogen levels decrease and remain low, increasing the risk of thromboembolism.
Step-by-step explanation:
The statement is True. During pregnancy and the immediate puerperium, clotting factors and fibrinogen levels normally decrease and remain low, resulting in a hypocoagulable state. This state increases the risk of thromboembolism, especially after cesarean birth. Thromboembolism refers to the formation of a blood clot (thrombus) that travels through the bloodstream and can block a blood vessel.
