Trivia Quiz: Stages Of Labor
Welcome to the trivia Quiz on the Stages of Labor. There are generally three stages of labor with the final one being the placenta being delivered. As medical practitioners, how much do you know about labor, where it starts and where it ends? The quiz below will refresh your memory, do give it a try and get to find out!
- 1.What are the three recognized hormonal changes that increase uterine excitability?
- A.
Estrogen/Progesterone ratio decreases
- B.
Estrogen/Progesterone ratio increases
- C.
Oxytocin release from the anterior pituitary
- D.
Oxytocin release from the posterior pituitary
- E.
Aldosterone/prostacyclin release from the fetus and fetal membrane, respectively
- F.
Cortisol/prostaglandin release from fetus and fetal membranes, respectively
- 2.Fill in the blanks: put the word that should go in each blank in the text box below, separated by comas. Facts about oxytocin: The _________ increases its amount of oxytocin receptors and responsiveness the a given dose of oxytocin in the last few months of pregnancy. The ______ of oxytocin release by the posterior pituitary spikes at labor. In animals without a pituitary gland, _____ is prolonged. _________ or irritation of the cervix is transmitted by nerve signals back to the hypothalamus which increases oxytocin secretion.
- 3.Which of the following is true (you can choose more than one)?
- A.
Smooth muscle of the uterus increases its contractility when stretched
- B.
Multiple gestation expedites delivery because of stretching/irritation of cervix
- C.
Abdominal musculature is inhibited during labor and delivery
- D.
Braxton Hicks contractions occur during labor
- E.
The cervix hardens toward the end of pregnancy because of the increasing weight of the fetus
- F.
Fetal membranes include the chorion and amnion
- 4.

- 7.Please describe how exogenous oxytocin administration could kill the baby if given excess during the 2nd stage of labor, but also save the mother if given in the 3rd stage of labor. What is the underlying physiology that connects these two facts?
