ATI LPN N105 Maternity Exam Questions
Extract:
Expectant parents
Question 1 of 5
The nurse is educating a class of expectant parents about fetal development. What is considered fetal age of viability?
Correct Answer: C
Rationale: At 8 weeks, the embryo is transitioning into the fetal stage and is not viable outside the womb. At 14 weeks, the fetus is too underdeveloped for survival. While 24 weeks is considered reasonable viability with intensive support, 20 weeks is often cited as the lower threshold due to improved neonatal care.
Extract:
None
Question 2 of 5
A nurse is assisting with the preparation of an educational program on physiological changes during labor. Which of the following smooth muscle adaptations should the nurse identify as being responsible for facilitating cervical dilation and promoting descent of the fetus into the client pelvis and vaginal canal?
Correct Answer: A
Rationale: Uterine smooth muscle relaxation and contractions facilitate cervical dilation and fetal descent. Cervical constriction, pelvic stretching, and vaginal contractions are not primary mechanisms.
