_______
Domain: 1: Labor Physiology, Stages of Labor & Pain Management — Questions 1–10
_________________________________________________________________________
_______
1. The four factors that affect the labor process are known as the "four Ps." Which of the
following correctly lists these factors?
A) Power, Passageway, Passenger, Psyche
B) Pressure, Position, Pelvis, Pain
C) Presentation, Position, Station, Stage
, D) Power, Pelvis, Presentation, Placenta
Correct Answer: A) Power, Passageway, Passenger, Psyche
Rationale: The four Ps of labor are Powers (uterine contractions), Passageway (maternal pelvis and
soft tissues), Passenger (fetus and placenta), and Psyche (maternal psychological state). These factors
interact to influence labor progression and outcomes.
2. During the first stage of labor, the latent phase is characterized by cervical dilation from
0 to approximately:
A) 3 cm
B) 6 cm
C) 5 cm
D) 8 cm
Correct Answer: B) 6 cm
Rationale: The latent phase of the first stage of labor extends from 0 to 6 cm of cervical dilation. The
active phase begins at approximately 6 cm. This threshold was updated from the older definition of 4
cm based on contemporary research on labor progress.
3. The nurse notes that a laboring patient's contractions occur every 3 minutes, last 60
seconds, and are moderate to strong in intensity. This pattern is characteristic of which
phase of labor?
A) Latent phase
B) Active phase
C) Transition phase
D) Second stage
Correct Answer: B) Active phase
Rationale: In the active phase of the first stage of labor, contractions typically occur every 2-5
minutes, last 45-70 seconds, and are moderate to strong. The latent phase has milder, less frequent
contractions. Transition contractions are stronger, closer together, and longer in duration.
4. Which hormone is primarily responsible for stimulating uterine contractions during
labor?
A) Estrogen
B) Progesterone
C) Oxytocin
D) Prostaglandin
Correct Answer: C) Oxytocin
Rationale: Oxytocin is the primary hormone that stimulates rhythmic uterine contractions during
labor. It is released from the posterior pituitary gland in response to cervical stretching and uterine
distension. Prostaglandins also play a role in cervical ripening and contractility.
5. The second stage of labor begins with complete cervical dilation (10 cm) and ends with:
A) Delivery of the placenta
B) Delivery of the newborn
C) Rupture of membranes
D) Onset of urge to push
Correct Answer: B) Delivery of the newborn
Rationale: The second stage of labor begins when the cervix is fully dilated (10 cm) and ends with the
birth of the newborn. The third stage begins after delivery and ends with the expulsion of the
placenta.
6. When assessing a patient's contraction pattern, the nurse documents the frequency as
"every 4 minutes." This means the nurse measured from:
A) The beginning of one contraction to the beginning of the next
B) The peak of one contraction to the peak of the next
C) The end of one contraction to the beginning of the next
D) The beginning of one contraction to the end of the same contraction
