Question: 1 / 400

What is the initial fetal heart rate characteristic when a mother experiences significant blood loss?

Bradycardia

Tachycardia

When a mother experiences significant blood loss, the initial fetal heart rate characteristic tends to be tachycardia, or an increased heart rate. This response occurs as the fetus's body reacts to the decreased oxygen supply and potential hypoxia resulting from maternal hemorrhage. The increased heart rate is an attempt by the fetus to maintain adequate oxygen delivery to vital organs, compensating for the adverse environmental changes.

The fetal heart compensates for a potential state of distress by increasing its rate of blood flow and cardiac output; therefore, tachycardia serves as an important early warning sign that the fetus may be experiencing a compensatory mechanism due to maternal blood loss. Continued monitoring of the fetal heart rate following this initial tachycardia can provide insight into the ongoing status of fetal well-being and the effectiveness of any interventions.
