120 Review Questions with Verified Solutions | NCLEX-PN Aligned | 2026-2027
Section 1: Reproductive Anatomy, Physiology, and Conception
Q1:
A nursing student is reviewing the female reproductive system for an upcoming ATI PN Maternal
Newborn exam. The student asks the instructor which structure of the uterus is the uppermost
portion that rises above the points of insertion of the fallopian tubes. Which response by the
instructor is correct?
A. A. Corpus
B. B. Cervix
C. C. Fundus [CORRECT]
D. D. Isthmus
Correct Answer: C
Rationale:
The fundus is the dome-shaped uppermost portion of the uterus that rises above the insertion points of the
fallopian tubes. The corpus is the main body of the uterus, the cervix is the narrow lower portion that
opens into the vagina, and the isthmus is the constricted region between the corpus and cervix.
Understanding uterine anatomy is essential for ATI PN exam questions on fundal assessment postpartum
and Leopold maneuvers during labor, per the 2026-2027 ATI PN Maternal Newborn content blueprint.
Q2:
A nurse is teaching a health class about the menstrual cycle. Which statement by the nurse
accurately describes the event that triggers ovulation in a typical 28-day cycle?
A. A. A sudden drop in progesterone levels from the corpus luteum
B. B. A surge in luteinizing hormone (LH) from the anterior pituitary [CORRECT]
C. C. A peak in follicle-stimulating hormone (FSH) during the follicular phase
D. D. A sustained increase in estrogen from the developing follicle
Correct Answer: B
Rationale:
Ovulation is triggered by a surge in luteinizing hormone (LH) from the anterior pituitary gland, typically
occurring around day 14 of a 28-day cycle. While rising estrogen levels from the developing follicle
stimulate the LH surge (positive feedback), it is the LH surge itself that directly triggers release of the
mature ovum. Progesterone drop occurs later if fertilization does not happen. FSH peaks earlier during
the follicular phase to stimulate follicle development, not to trigger ovulation. This distinction is frequently
tested on the ATI PN Maternal Newborn proctored exam.
Q3:
A nurse is providing preconception counseling to a couple trying to conceive. The nurse explains
that fertilization normally occurs in which anatomic location?
A. A. Endometrial cavity of the uterus
B. B. Fimbriated end of the fallopian tube
C. C. Ampulla of the fallopian tube [CORRECT]
D. D. Cervical canal near the internal os
Correct Answer: C
Rationale:
Fertilization normally occurs in the ampulla of the fallopian tube, which is the widest section of the tube.
The ovum is released from the ovary at ovulation and is picked up by the fimbriae. It then travels into the
ampulla where it encounters sperm. Fertilization must occur within approximately 24 hours of ovulation
for the ovum to remain viable. The endometrial cavity is where implantation occurs 6 to 10 days after
fertilization, and the cervical canal is the passage sperm must traverse but not the site of fertilization. This
is a high-yield ATI PN fact.
Q4:
,A nurse is educating a patient about the endometrial cycle. The nurse explains that during the
secretory phase, which hormone is primarily responsible for the endometrial changes that
prepare for possible implantation?
A. A. Estrogen
B. B. Progesterone [CORRECT]
C. C. Follicle-stimulating hormone
D. D. Luteinizing hormone
Correct Answer: B
Rationale:
Progesterone, produced by the corpus luteum after ovulation, is primarily responsible for the secretory
phase changes in the endometrium. During this phase, the endometrium becomes thick, vascular, and
glandular to support possible implantation of a fertilized ovum. Estrogen drives the proliferative phase
that rebuilds the endometrium after menstruation. FSH and LH are pituitary hormones that regulate the
ovarian cycle, not directly the endometrial changes. Differentiating the hormonal drivers of each
endometrial phase is a key competency for the ATI PN Maternal Newborn examination.
Q5:
A pregnant patient at 10 weeks gestation asks the nurse what function human chorionic
gonadotropin (hCG) serves during early pregnancy. Which response by the nurse is most
accurate?
A. A. hCG maintains the corpus luteum so it continues producing progesterone and estrogen [CORRECT]
B. B. hCG directly stimulates uterine growth and development of the decidua
C. C. hCG promotes breast development for lactation throughout pregnancy
D. D. hCG enhances glucose transport from the mother to the developing fetus
Correct Answer: A
Rationale:
hCG supports the corpus luteum, ensuring continued production of progesterone and estrogen during
early pregnancy until the placenta takes over hormonal production around 10 to 12 weeks. hCG peaks at 8
to 10 weeks and is the hormone detected in pregnancy tests. It does not directly stimulate uterine growth,
promote breast development (that is human placental lactogen), or enhance glucose transport.
Understanding the distinct functions of pregnancy hormones is essential for the ATI PN Maternal
Newborn proctored exam, as questions frequently test hCG versus hPL versus progesterone roles.
Q6:
A nursing instructor is teaching students about the placenta. Which statement by a student
indicates an accurate understanding of placental function?
A. A. The placenta serves as a complete barrier that prevents all substances from crossing to the
fetus
B. B. The placenta transports oxygen, nutrients, and antibodies while removing waste products [CORRECT]
C. C. The placenta produces only progesterone and estrogen throughout the pregnancy
D. D. The placenta prevents all bacteria and viruses from reaching the fetal circulation
Correct Answer: B
Rationale:
The placenta functions as an endocrine organ and the primary interface for maternal-fetal exchange,
transporting oxygen and nutrients to the fetus while removing carbon dioxide and waste products. It also
allows passive transfer of maternal IgG antibodies, providing the fetus with temporary immunity.
However, it is NOT a complete barrier; certain pathogens (TORCH infections such as rubella,
cytomegalovirus, and toxoplasmosis), drugs, alcohol, and some viruses can cross the placenta. The
placenta produces multiple hormones including hCG, hPL, progesterone, and estrogen. This distinction
about partial placental barrier function is a critical ATI PN concept.
Q7:
A nurse is reviewing the hormonal changes of pregnancy with a nursing student. The nurse
explains that human placental lactogen (hPL) performs which primary function?
A. A. Supports the corpus luteum during the first trimester
B. B. Promotes breast development for lactation and alters maternal glucose metabolism [CORRECT]
C. C. Stimulates uterine contractions during the third trimester
, D. D. Prevents the maternal immune system from rejecting the fetus
Correct Answer: B
Rationale:
Human placental lactogen (hPL), also called human chorionic somatomammotropin, promotes breast
development for lactation and increases maternal insulin resistance to make more glucose available for
fetal growth. This alteration in maternal glucose metabolism is why gestational diabetes screening is
performed at 24 to 28 weeks. hCG (not hPL) supports the corpus luteum. Oxytocin stimulates uterine
contractions. Progesterone (not hPL) plays a major immunosuppressive role. Differentiating hPL from hCG
and progesterone is frequently tested on the ATI PN Maternal Newborn exam.
Q8:
A patient asks the nurse when the fertilized ovum normally implants into the endometrium after
fertilization. Which time frame should the nurse provide?
A. A. Within 24 to 48 hours after fertilization
B. B. Approximately 3 to 5 days after fertilization
C. C. Approximately 6 to 10 days after fertilization [CORRECT]
D. D. Approximately 14 days after fertilization
Correct Answer: C
Rationale:
Implantation of the fertilized ovum into the endometrium normally occurs approximately 6 to 10 days after
fertilization. After fertilization in the ampulla, the zygote undergoes cell division as it travels through the
fallopian tube, becoming a blastocyst by approximately day 5. Implantation typically occurs around day 7
to 9 post-fertilization. The 24 to 48 hour timeframe is too early (the zygote is still traversing the fallopian
tube). The 14-day timeframe corresponds to when the next menstrual period would be expected, not
implantation. This timeline is a frequently tested ATI PN Maternal Newborn concept.
Q9:
A nursing student is learning about the ovarian cycle. Which sequence correctly describes the
phases of the ovarian cycle in order?
A. A. Luteal phase, follicular phase, ovulation
B. B. Follicular phase, ovulation, luteal phase [CORRECT]
C. C. Ovulation, follicular phase, luteal phase
D. D. Follicular phase, luteal phase, ovulation
Correct Answer: B
Rationale:
The correct sequence of the ovarian cycle is: follicular phase (days 1 to 14), ovulation (approximately day
14), and luteal phase (days 15 to 28). During the follicular phase, FSH stimulates several follicles to
develop, with one becoming dominant. Ovulation is triggered by the LH surge and involves release of the
mature ovum. During the luteal phase, the corpus luteum forms and secretes progesterone to prepare the
endometrium. If fertilization does not occur, the corpus luteum degenerates and the cycle restarts.
Understanding the correct sequence and hormonal drivers is fundamental for the ATI PN Maternal
Newborn proctored exam.
Q10:
A nurse is explaining the menstrual cycle to a group of adolescent females. The nurse correctly
states that which phase of the endometrial cycle is driven primarily by estrogen?
A. A. Menstrual phase
B. B. Secretory phase
C. C. Proliferative phase [CORRECT]
D. D. Ischemic phase
Correct Answer: C
Rationale:
The proliferative phase of the endometrial cycle is driven primarily by estrogen, which is produced by the
developing ovarian follicles during the follicular phase of the ovarian cycle. Estrogen stimulates
regeneration and thickening of the endometrium after it has been shed during menstruation. The
secretory phase is driven by progesterone from the corpus luteum. The menstrual phase occurs when
estrogen and progesterone levels drop, causing endometrial shedding. The ischemic phase is a brief
period of vasoconstriction just before menstruation. Differentiating which hormone drives each
