Florida State Paramedic Practice Exam

What is indicated by a woman's vital signs showing decreased blood pressure and increased heart rate during pregnancy?

1. Total shock state

2. Normal adaptation to pregnancy

3. Postpartum hemorrhage risk

4. Normal hydration level

The correct answer is: Postpartum hemorrhage risk

The vital signs of decreased blood pressure and increased heart rate in a pregnant woman could suggest several physiological changes or conditions. However, this specific pattern of vital signs often indicates that the body may be compensating for a decrease in effective circulating blood volume, which might occur during a postpartum hemorrhage scenario. During pregnancy, the cardiovascular system adapts by increasing blood volume and reducing vascular resistance, which generally helps maintain stable blood pressure. A significant drop in blood pressure alongside an increased heart rate suggests that the body is experiencing stress and attempting to maintain perfusion to vital organs. In cases of postpartum hemorrhage, the loss of blood can lead to hypovolemic shock, which is characterized by low blood pressure and compensatory tachycardia (increased heart rate) as the heart works harder to maintain adequate circulation. This vital sign presentation highlights the importance of monitoring for potential complications in pregnancy, particularly after delivery, where the risk of hemorrhage is heightened due to factors like uterine atony or retained placental fragments. Thus, while the body does adapt during pregnancy, the combination of these vital signs typically points towards a concerning situation requiring immediate assessment and intervention.
