Answer to Question 1

1
1. Correct. Full dilation may occur in less than 1 hour, but in first-time pregnancies it can take up to 20 hours.
2. Incorrect. Second stage is from full dilation to birth and takes an average of 20 to 50 mi-nutes, although 2 hours is still considered normal.
3. Incorrect. Third stage is from birth to expulsion of the placenta and usually takes a few minutes.
4. Incorrect. Fourth stage begins after expulsion of the placenta and lasts until homeostasis is reestablished (about 2 hours).

1, 3, 4. Incorrect. In normal labor, a single fetus presents by vertex; proceeds through a regular progression of contractions, effacement, dilation, and descent; presents no complications; and does so in under 18 hours.
2. Correct. In normal labor, a single fetus presents by vertex; proceeds through a regular pro-gression of contractions, effacement, dilation, and descent; presents no complications; and does so in under 18 hours.
