Answer to Question 1

ANS: A
Uterine stimulants, primarily oxytocin, given in low-dose infusions after delivery of the fetus and placenta, help stimulate firm uterine contractions to reduce the risk of postpartum hemorrhage from an atonic uterus. Magnesium sulfate is given to treat eclampsia and preeclampsia. Vitamin K is given to prevent hemorrhage. Dopamine is given to treat hypotension.

Answer to Question 2

ANS: D
Terbutaline is a beta-adrenergic receptor stimulant, which acts primarily on the beta2 receptors. Stimulation of beta1 receptors produces uterine relaxation and relaxation of the bronchial and vascular smooth muscle. In higher doses, terbutaline will stimulate the beta1 receptors, which raises heart rate. Magnesium sulfate is given to treat eclampsia. Oxytocin is given to produce uterine contractions. Levonorgestrel is a progestin given for contraception.
