Answer to Question 1
Ans: B
Feedback:
Oxytocin is given intramuscularly (IM) during the third stage of labor. It is the time period from when the neonate is expelled until the placenta is expelled. Oxytocin is given intramuscularly to produce uterine contractions and control postpartum bleeding and hemorrhage. Oxytocin is not given intravenously, subcutaneously, or intranasally during the third stage of labor.
Answer to Question 2
Ans: B
Feedback:
Drugs used to prevent uterine contractions are called tocolytics. They are useful in the management of preterm labor. These drugs will decrease uterine activity and prolong the pregnancy to allow the fetus to develop more fully, thereby increasing the chance of neonatal survival. Oxytocic drugs are used antepartum (before birth of the neonate) to induce uterine contractions and initiate or augment labor. Tocolytics are not used for postpartum hemorrhage or protracted labor.
