Concerning the postpartum changes and developments in a woman's cardiovascular system, nurses should be aware that:
1. cardiac output, pulse rate, and stroke volume all return to prepregnancy normal within a few hours of childbirth.
2. respiratory function returns to nonpregnant levels by 6 to 8 weeks after birth.
3. lowered white blood count after pregnancy can lead to false positives when test-ing for infections.
4. a hypercoagulable state protects the new mother from thromboembolism, espe-cially after a cesarean birth.
