A nurse is caring for a client who is postpartum and experiencing excessive vaginal bleeding. Which of the following medications should the nurse plan to administer?
A.
Nifedipine
B.
Terbutte
C.
Oxytocin
D.
Betamethasone
The Correct Answer and Explanation is:
The correct answer is C. Oxytocin.
Explanation:
Oxytocin is a medication commonly used in the postpartum period to control excessive vaginal bleeding caused by uterine atony, which is the most frequent cause of postpartum hemorrhage (PPH). Uterine atony refers to the inability of the uterus to contract effectively after childbirth. When the uterus fails to contract, blood vessels that supplied the placenta remain open, leading to excessive bleeding. Oxytocin stimulates the uterine muscles to contract, helping to compress these blood vessels, which reduces blood flow and promotes hemostasis.
Role of Oxytocin:
- Promotes Uterine Contraction: Oxytocin is a synthetic form of the naturally occurring hormone that stimulates uterine contractions during and after childbirth. Administering oxytocin in the postpartum period helps to contract the uterus and prevent or treat excessive bleeding (postpartum hemorrhage).
- First-Line Treatment: It is typically the first-line medication for managing uterine atony and controlling postpartum hemorrhage because of its effectiveness in inducing uterine contractions.
Why the Other Medications Are Incorrect:
- A. Nifedipine: Nifedipine is a calcium channel blocker primarily used to treat hypertension and sometimes to manage preterm labor by relaxing the uterus. It is not used to treat postpartum hemorrhage or excessive vaginal bleeding.
- B. Terbutaline: Terbutaline is a beta-adrenergic agonist used to delay preterm labor by relaxing the uterus. It is contraindicated in the postpartum period when uterine contractions are needed to control bleeding.
- D. Betamethasone: Betamethasone is a corticosteroid given during pregnancy to enhance fetal lung maturity in cases of preterm labor. It has no role in managing postpartum hemorrhage.
Clinical Relevance:
Postpartum hemorrhage is a serious and potentially life-threatening condition, defined as blood loss of more than 500 mL after a vaginal delivery or more than 1,000 mL after a cesarean section. Quick and effective management, including the administration of uterotonic agents like oxytocin, is crucial to prevent severe complications such as hypovolemic shock or maternal death.
