Medications used to manage postpartum hemorrhage (PPH) include: (Select all that apply)
Hemabate.
Terbutaline.
Oxytocin.
Methergine.
Correct Answer : A,C,D
Choice A rationale
Hemabate (carboprost) is a prostaglandin analog that induces uterine contractions, effectively reducing bleeding. It is often used when first-line agents fail to control postpartum hemorrhage.
Choice B rationale
Terbutaline is a tocolytic agent used to delay premature labor by relaxing uterine muscles. It is contraindicated in postpartum hemorrhage as it inhibits uterine contraction, worsening bleeding.
Choice C rationale
Oxytocin stimulates uterine contractions by acting on oxytocin receptors in the myometrium. It is the first-line treatment for postpartum hemorrhage to promote hemostasis through uterine contraction.
Choice D rationale
Methergine (methylergonovine) enhances uterine tone and decreases bleeding by inducing sustained contractions via stimulation of uterine smooth muscle serotonin and alpha-adrenergic receptors.

Correct Answer is D
Explanation
Choice A rationale
While conjunctival irritation could occur from exposure to irritants, it is not a primary concern in this case. Respiratory complications take precedence due to the risk of aspiration from meconium-stained fluid.
Choice B rationale
Rectal temperature assessment for hyperthermia is important but not critical in the immediate scenario. Respiratory distress monitoring is more urgent due to the association with meconium aspiration syndrome.
Choice C rationale
Bathing to remove meconium-stained fluid minimizes infection risk. However, respiratory assessment is more critical due to the severe pulmonary complications associated with meconium aspiration.
Choice D rationale
Meconium-stained amniotic fluid increases the risk of aspiration, leading to respiratory distress. Early respiratory evaluation prevents hypoxia, pulmonary hypertension, or pneumonitis, which are serious complications in neonates.
Correct Answer is B
Explanation
Choice A rationale
Surgical intervention is not the initial step for uterine atony as conservative measures, such as fundal massage, are prioritized to encourage uterine contraction and reduce bleeding.
Choice B rationale
Fundal massage stimulates uterine contraction by mechanically compressing the myometrium, which helps to constrict the spiral arteries and reduce hemorrhage caused by uterine atony.
Choice C rationale
Establishing venous access is critical for fluid resuscitation but does not directly address the underlying cause of hemorrhage, which requires mechanical or pharmacological uterine contraction.
Choice D rationale
Catheterizing the bladder can prevent displacement of the uterus but does not directly address uterine atony. An empty bladder supports fundal massage by allowing proper uterine positioning.
