Physiological AdaptationQuestion 1019 of 2368

Which pregnancy-related changes increase a client's risk for venous thrombus formation?

  1. Decreased plasma fibrinogen and an increased platelet count in late pregnancy
  2. Decreased blood volume and a slowed heart rate from the weight of the uterus
  3. Increased blood coagulability and blood pooling from the weight of the uterus
  4. Increased red cell destruction and decreased fibrin from hormonal changes
Show answer

Correct answer: Increased blood coagulability and blood pooling from the weight of the uterus

Hypercoagulability plus pooling of blood in the legs from uterine weight raises thrombus risk.
