What is the amount of heavy vaginal bleeding in cesarean delivery that may indicate postpartum hemorrhage?
> 500 mL
> 1000 mL
< 500 mL
< 1000 mL
The Correct Answer is A
Heavy vaginal bleeding in cesarean delivery that may indicate postpartum hemorrhage is more than 500 mL.
Postpartum hemorrhage (PPH) is severe bleeding and loss of blood after childbirth. It’s a serious and dangerous condition that can lead to death.
Choice B is wrong because more than 1000 mL of blood loss is too high for the definition of PPH after cesarean delivery.
Choice C is wrong because less than 500 mL of blood loss is normal after cesarean delivery.
Choice D is wrong because less than 1000 mL of blood loss is not considered heavy bleeding after cesarean delivery.

Correct Answer is A
Explanation
The specific gravity of urine is a measure of the concentration of solutes in urine.
It reflects the ability of the kidneys to regulate water balance and excrete waste products.The normal range for urine specific gravity is1.005 to 1.030.
In postpartum hemorrhage, there is a loss of blood volume that leads to decreased blood pressure and reduced perfusion of the kidneys.The kidneys respond by conserving water and producing concentrated urine with a high specific gravity, usuallygreater than 1.030.
ChoiceBis wrong because a urine specific gravity lower than 1.030 indicates a dilute urine that is not consistent with postpartum hemorrhage.
ChoiceCis wrong because a urine specific gravity greater than 1.020 is still within the normal range and does not reflect the degree of water conservation that occurs in postpartum hemorrhage.
ChoiceDis wrong because a urine specific gravity lower than 1.020 indicates a very dilute urine that suggests excessive fluid intake, diabetes insipidus, or kidney failure.
These conditions are not associated with postpartum hemorrhage.
Correct Answer is B
Explanation
relaxed uterus may indicate internal bleeding in postpartum hemorrhage.This is because the uterus is not contracting properly to compress the blood vessels where the placenta was attached, leading to excessive blood loss.A relaxed uterus is also known as uterine atony, which is the most common cause of postpartum hemorrhage.
Choice A is wrong because a tense and rigid uterus may indicate retained placenta or uterine clot, which are other causes of postpartum hemorrhage.
These conditions prevent the uterus from contracting fully and expelling the placental fragments or clots.
Choice C is wrong because a soft uterus is similar to a relaxed uterus and may also indicate internal bleeding in postpartum hemorrhage.
Choice D is wrong because a normal uterus is not a sign of postpartum hemorrhage.A normal uterus should be firm and contracted after delivery to prevent excessive bleeding.
Normal ranges for blood loss after delivery are less than 500 mL for vaginal delivery and less than 1000 mL for cesarean delivery.Postpartum hemorrhage is defined as blood loss of more than these amounts or blood loss accompanied by signs of hypovolemia within 24 hours of delivery.
