SECTION 1: LABOR & DELIVERY ASSESSMENT (Questions 1–30)
1. What is the normal range for cervical dilation?
A) 0–100%
B) 0–10 cm
C) –5 to +5 cm
D) 0–5 cm
Answer: B) 0–10 cm
Rationale: Cervical dilation refers to the opening of the cervix measured in centimeters from 0 cm
(closed) to 10 cm (fully dilated). Cervical effacement is measured in percentages (0–100%).
2. Which pelvic type is considered the MOST favorable for vaginal birth?
A) Anthropoid pelvis
B) Gynecoid pelvis
C) Platypelloid pelvis
D) Android pelvis
Answer: B) Gynecoid pelvis
Rationale: The gynecoid pelvis is the classic female pelvis and is considered the most favorable for
vaginal birth. It has a rounded inlet, adequate capacity, and optimal dimensions.
,3. Which pelvic type would MOST likely lead to cesarean delivery?
A) Anthropoid
B) Gynecoid
C) Platypelloid
D) Android
Answer: C) Platypelloid
Rationale: The platypelloid pelvis is flat with a widened transverse diameter and a shortened
anteroposterior diameter, making vaginal delivery difficult and often resulting in cesarean section.
4. What is effacement?
A) The opening of the cervix
B) The softening, thinning, and shortening of the cervix
C) The descent of the fetal head into the pelvis
D) The rupture of amniotic membranes
Answer: B) The softening, thinning, and shortening of the cervix
Rationale: Effacement is measured from 0% (long and thick) to 100% (fully effaced).
5. Which of the following are part of the "Five P's" essential for labor and birth? (Select all that apply)
,A) Positivity
B) Psyche
C) Position
D) Power
E) Pressure
Answer: B, C, D – Psyche, Position, and Power
Rationale: The 5 P's of labor are: Passageway (pelvis and cervix), Passenger (fetal head, attitude, lie, and
presentation), Position (station, engagement, and position), Powers (primary and secondary), and
Psyche (emotions, energy, support).
6. What must occur before pushing can begin during labor?
A) The mother must be fully hydrated
B) The cervix must be fully dilated and effaced
C) The fetal heart rate must be >160 bpm
D) The mother must receive an epidural
Answer: B) The cervix must be fully dilated and effaced
Rationale: The cervix must be completely dilated (10 cm) and fully effaced (100%) before pushing can
begin to prevent cervical injury and allow for effective delivery.
7. A woman enters triage stating she "thinks" she is in labor. Which assessment BEST demonstrates
TRUE labor?
A) Fetus palpable
, B) Contractions every 20–30 minutes
C) Change/progress in cervical dilation/effacement
D) Fetal heart rate alterations
Answer: C) Change/progress in cervical dilation/effacement
Rationale: True labor is characterized by progressive cervical change (dilation and effacement).
Contractions alone do not confirm true labor unless they produce cervical change.
8. Premonitory signs of impending labor include: (Select all that apply)
A) Lightening
B) Braxton Hicks contractions
C) Cervical changes
D) Increased fetal movement
Answer: A, B, C – Lightening, Braxton Hicks contractions, and Cervical changes
Rationale: Premonitory signs include lightening (fetal descent), Braxton Hicks contractions, cervical
changes (softening, effacement, and early dilation), and a bloody show.
9. What is the normal fetal heart rate (FHR) range?
A) 80–100 bpm
B) 100–120 bpm
C) 110–160 bpm
D) 160–200 bpm
