← Human Body & HealthFollowing placental abruption, which compensation mechanism increases maternal heart rate?
A)Baroreceptor arterial pressure reflex✓
B)Increased antidiuretic hormone release
C)Decreased erythropoietin secretion
D)Chemoreceptor respiratory drive alterations
💡 Explanation
Placental abruption causes rapid blood loss, triggering the baroreceptor arterial pressure reflex that increases heart rate to maintain blood pressure; therefore, the reflex response supports circulation rather than ADH increase, erythropoietin changes, or ventilation modulation.
