Correct Answer: D
(A) The second stage of labor is from full cervical dilation through birth of the baby. The three phases of this stage include latency or resting, descent, and final transition. The client is less than fully dilated so she is not in stage 2. (B) The first stage of labor begins with regular uterine contractions and continues until the woman is 10 cm dilated. The three phases of this stage include the early or latent phase (0-3 cm), the active phase (4-7 cm), and the transitional phase (7-10 cm). The client is <4 cm dilated so she is in the latent phase of the first stage of labor. (C) The third stage of labor is from the birth of the baby until the delivery of the placenta. The client is less than fully dilated. (D) The first stage of labor begins with regular uterine contractions and continues until the woman is 10 cm dilated. The three phases of this stage include the early orlatent phase (0-3 cm), the active phase (4-7 cm), and the transitional phase (7-10 cm).
