Naegele's Rule Q6: How do you calculate the estimated due date using Naegele's Rule? A) Add 1 year and subtract 3 months from LMP B) Subtract 3 months and add 7 days to LMP C) Add 3 months and subtract 7 days from LMP D) Add 1 month and add 1 week to LMP Answer: A) Add 1 year and subtract 3 months from LMP Elaboration: Naegele's Rule estimates the due date by adding one year, subtracting three months, and adding seven days to the last menstrual period. 7. Signs of Pregnancy (Presumptive, Probable, Positive) Q7: Which of the following is considered a positive sign of pregnancy? A) Amenorrhea B) Breast tenderness C) Fetal heartbeat detected by a Doppler D) Quickening Answer: C) Fetal heartbeat detected by a Doppler Elaboration: Positive signs of pregnancy are definitive indicators such as the detection of fetal heart tones, observable fetal movements, or visualization of the fetus via ultrasound. 8. Trimesters Q8: How many trimesters are there in a typical pregnancy?

A) Complete dilation of the cervix B) The descent of the fetus through the birth canal C) Regular uterine contractions leading to cervical dilation D) Expulsion of the placenta Answer: C) Regular uterine contractions leading to cervical dilation Elaboration: The first stage of labor involves the onset of regular contractions and gradual cervical dilation, lasting until full dilation (10 cm). 10. True vs. False Labor Q10: Which of the following is a characteristic of false labor? A) Contractions become progressively stronger B) Contractions are irregular and may stop with activity C) Cervical dilation occurs D) Contractions are accompanied by rupture of membranes Answer: B) Contractions are irregular and may stop with activity Elaboration: False labor (Braxton Hicks contractions) typically involves irregular contractions that do not lead to cervical dilation and may cease with changes in activity. 11. 5 P's that Affect the Labor Process Q11: Which of the following is NOT one of the 5 P's affecting the labor process? A) Passenger B) Passage C) Position D) Pain Answer: D) Pain Elaboration: The 5 P's of labor include Passenger (fetus), Passage (birth canal), Powers (contractions), Position (of the mother), and Psychologic response. Pain is a result of labor but not a determining factor. 12. Fetal Monitoring Q12: What is the primary purpose of continuous fetal monitoring during labor? A) To assess maternal comfort B) To evaluate fetal heart rate and detect potential distress C) To measure uterine contractions D) To monitor maternal blood pressure Answer: B) To evaluate fetal heart rate and detect potential distress Elaboration: Continuous fetal monitoring helps assess the fetus's heart rate patterns during labor, allowing for early detection of fetal distress. 13. Assessment of Contractions Q13: What is the best method to assess the frequency of uterine contractions during labor? A) Palpation of the abdomen B) Maternal report C) Electronic fetal monitoring D) Ultrasound Answer: C) Electronic fetal monitoring Elaboration: Electronic fetal monitoring provides accurate data on the frequency, duration, and intensity of uterine contractions, essential for assessing labor progress. 14. Newborn Assessment Q14: What is a critical assessment finding in a newborn that requires immediate attention? A) Apgar score of 7 at 1 minute B) Heart rate of 120 bpm C) Cyanosis of the lips and face D) Weight of 6 pounds Answer: C) Cyanosis of the lips and face Elaboration: Cyanosis in a newborn indicates insufficient oxygenation and requires immediate evaluation and intervention. 15. Postpartum Assessment Q15: Which assessment is essential during the postpartum period to monitor for potential complications? A) Assessing fetal heart rate B) Monitoring for signs of infection and hemorrhage C) Measuring fundal height D) Checking maternal weight Answer: B) Monitoring for signs of infection and hemorrhage Elaboration: Postpartum assessments should focus on signs of infection and hemorrhage, as these can lead to serious complications. 16.
