Question 1

What is the normal duration of human pregnancy?

Accepted Answer

Answer reason: The normal duration of human pregnancy is about 280 days (40 weeks) when dated from the first day of the last menstrual period (LMP), which is the standard obstetric convention. This corresponds to approximately 38 weeks from conception/ovulation. The other options are either too short (240, 260 days) or longer than the typical term (300 days). Therefore, 280 days is the best answer.
Category reason: This question tests a foundational fact about human gestation length, which is a core concept within reproductive biology rather than a nursing intervention or clinical judgment scenario.

Question 2

Which vitamin deficiency is associated with ovulation problems?

Accepted Answer

Answer reason: Vitamin D receptors are present in reproductive tissues (including ovary and endometrium), and vitamin D plays a role in follicular development and steroid hormone regulation. Deficiency has been associated with ovulatory dysfunction and infertility, including in conditions like PCOS. In contrast, vitamins A, C, and K are not classically linked to primary ovulation failure in standard nursing/medical teaching. Therefore, vitamin D deficiency is the best match among the options.
Category reason: The question tests foundational knowledge about how micronutrient status can affect female reproductive physiology and ovulation, which fits best under the Reproductive System rather than nursing interventions or clinical prioritization.

Question 3

The term for male sex cells?

Accepted Answer

Answer reason: Male sex cells are called sperm (spermatozoa), which are the male gametes produced in the testes. They carry paternal genetic material and are motile to reach and fertilize the female gamete (egg/ovum). The egg is the female sex cell, while pupa and pupil are unrelated terms.
Category reason: This question tests basic knowledge of human gametes and reproduction, which falls under the Reproductive System in Nursing Science.

Question 4

What is the first-line management for unexplained infertility?

Accepted Answer

Answer reason: In unexplained infertility, initial treatment is typically the least invasive, most cost-effective approach that increases the chance of fertilization, which is ovulation induction combined with intrauterine insemination (IUI). This strategy can improve timing and the number of available oocytes and places a higher concentration of motile sperm closer to the oocyte. IVF is generally reserved for cases that fail first-line therapy or when additional factors (e.g., advanced maternal age, prolonged infertility) justify escalation. ICSI and donor eggs are not first-line for unexplained infertility because they target specific indications (severe male factor, poor ovarian reserve/advanced age).
Category reason: This question tests knowledge of standard stepwise fertility treatment options and indications, which is primarily reproductive medicine content rather than nursing care prioritization or safety.

Question 5

Which sperm abnormality is linked with infertility?

Accepted Answer

Answer reason: Oligospermia refers to a low sperm count, which decreases the likelihood that sufficient sperm will reach and fertilize the ovum, making it a common cause of male-factor infertility. The other options are not sperm abnormalities: hyperplasia is a tissue growth pattern, and polycythemia/anemia are red blood cell disorders. Therefore, oligospermia is the best answer linked directly to infertility.
Category reason: This question tests foundational knowledge of male fertility and semen parameters, which is part of reproductive system science rather than nursing care decision-making.

Question 6

Vasectomy is process of?

Accepted Answer

Answer reason: A vasectomy is a permanent male contraceptive procedure in which the vas deferens are cut/occluded to prevent sperm from entering the ejaculate. This results in male sterilization while typically preserving testosterone production and sexual function. IUD and implant are female contraceptive methods, not vasectomy techniques. Therefore, the best answer is sterilization.
Category reason: This question tests foundational knowledge of contraception methods and male reproductive anatomy (vas deferens) rather than nursing care decisions, placing it in the Reproductive System subject area.

Question 7

At which stage in the uterine cycle does the secretory phase occur?

Accepted Answer

Answer reason: The secretory (luteal) phase of the uterine/endometrial cycle occurs after ovulation and is driven primarily by progesterone from the corpus luteum. During this time the endometrium becomes thick, edematous, and glandular to support potential implantation. In a typical 28-day cycle, this corresponds to approximately days 14–28, making option A the best answer.
Category reason: This question tests factual knowledge of the timing and phases of the uterine (endometrial) cycle, which is foundational reproductive physiology rather than a nursing intervention or clinical judgment scenario.

Question 8

Which of the below is a confirmed indication of pregnancy?

Accepted Answer

Answer reason: Confirmed (positive) signs of pregnancy are those that directly demonstrate the presence of a fetus, such as fetal cardiac activity seen on ultrasound. Nausea/vomiting and amenorrhea are presumptive symptoms and can occur in many nonpregnant conditions. Detection of beta-hCG in urine is considered a probable sign because it indicates pregnancy is likely but can be affected by false positives (e.g., trophoblastic disease) and does not directly visualize the fetus.
Category reason: The item tests classification of pregnancy indicators (presumptive, probable, positive) and focuses on reproductive/obstetric physiology and diagnosis, which best fits the Reproductive System subject rather than nursing intervention decision-making.

Question 9

The normal duration of human pregnancy is approximately?

Accepted Answer

Answer reason: Normal human gestation is dated as about 40 weeks (280 days) from the first day of the last menstrual period (LMP). This corresponds to approximately 9 calendar months but is more precisely expressed in weeks for obstetric dating. A duration of 42 weeks is considered post-term, and 36 weeks is preterm. Therefore, 40 weeks is the best approximate normal duration.
Category reason: This question tests foundational knowledge of normal gestational length and obstetric dating, which is part of the Reproductive System in nursing science rather than a nursing intervention or prioritization scenario.

Question 10

The placenta performs all the following functions except:

Accepted Answer

Answer reason: The placenta functions as an interface for maternal-fetal exchange, including oxygen/carbon dioxide exchange and transfer of nutrients to the fetus, while facilitating removal of fetal wastes. It also serves as an endocrine organ producing key hormones such as hCG, progesterone, and estrogens to support pregnancy. Digestion of food is a gastrointestinal function and is not performed by the placenta.
Category reason: This question tests foundational knowledge of placental functions in pregnancy, which is core content of the Reproductive System rather than nursing decision-making or care prioritization.

Question 11

What indicates normal involution on postpartum day 3?

Accepted Answer

Answer reason: After delivery, the uterine fundus should descend about 1 cm (approximately one fingerbreadth) per day and remain firm and midline. By postpartum day 3, a normal finding is a fundus about 3 cm below the umbilicus, consistent with expected involution. A fundus above the umbilicus suggests uterine atony or subinvolution, and a fundus shifted to the right commonly indicates a distended bladder. A fundus that is not palpable would be expected later (around 2 weeks postpartum), not on day 3.
Category reason: This question tests normal postpartum uterine involution (expected anatomical/physiologic changes of the uterus after birth), which is foundational knowledge within the Reproductive System.

Question 12

A patient at 10 weeks reports vaginal bleeding and lower abdominal pain. On exam, the cervix is open, and products of conception are visible. What is the diagnosis?

Accepted Answer

Answer reason: An inevitable abortion is characterized by vaginal bleeding and crampy abdominal pain with cervical dilation, indicating that pregnancy loss is in progress and cannot be prevented. Visible products of conception at the cervical os further supports an ongoing miscarriage rather than a threatened abortion (closed cervix). Complete abortion requires that all products of conception have already been expelled with a closed cervix and typically decreasing bleeding. Missed abortion involves fetal demise with retained products and a closed cervix, often with minimal or no bleeding.
Category reason: This item tests diagnostic criteria for types of early pregnancy loss based on clinical findings (bleeding, pain, cervical dilation, retained/visible products), which is foundational obstetric knowledge within the Reproductive System.

Question 13

The condition in which the umbilical cord is around the fetal body is call?

Accepted Answer

Answer reason: Umbilical cord around the fetal body/limbs is generally termed umbilical cord entanglement. A nuchal cord refers specifically to cord around the fetal neck, not the body in general. Cord prolapse is descent of the cord through the cervix into/through the vagina ahead of the presenting part, which is a different obstetric emergency. "Rounded cord" is not a standard clinical term for this condition.
Category reason: This item tests recognition of an obstetric/anatomical condition related to fetal-placental structures rather than nursing actions or prioritization, fitting foundational reproductive/obstetric science knowledge.

Question 14

'Fallopian Tube' is part of which of these human systems?

Accepted Answer

Answer reason: The fallopian tubes (uterine tubes) are female reproductive organs that transport the ovum from the ovary to the uterus and are the usual site of fertilization (commonly the ampulla). They connect the uterine cavity to the peritoneal cavity near the ovaries via fimbriae. Therefore, they belong to the reproductive system, not the respiratory, excretory, or digestive systems.
Category reason: This question tests identification of an anatomical structure and which body system it belongs to, which is foundational biomedical knowledge in the Reproductive System.

Question 15

What is the average duration of human pregnancy?

Accepted Answer

Answer reason: The average duration of human pregnancy is about 280 days (40 weeks) when dated from the first day of the last menstrual period (LMP), which is the standard obstetric method. This corresponds to roughly 266 days from conception, but most clinical dating uses LMP. Therefore, 280 days is the best answer among the options.
Category reason: This question tests foundational knowledge of normal gestational length and pregnancy dating, which is part of reproductive system science rather than a nursing judgment or intervention scenario.

Question 16

What is the first-line drug for ovulation induction in PCOS?

Accepted Answer

Answer reason: Letrozole (an aromatase inhibitor) is recommended as first-line for ovulation induction in anovulatory infertility due to PCOS because it yields higher ovulation, pregnancy, and live-birth rates compared with clomiphene in many patients. By lowering estrogen production, it reduces negative feedback at the hypothalamus/pituitary, increasing FSH and promoting follicular development. Clomiphene is an alternative first-line/second-line agent depending on guideline and patient factors, metformin is mainly used for insulin resistance and may be adjunctive, and gonadotropins are typically second-line due to higher risks (e.g., ovarian hyperstimulation and multiple gestation).
Category reason: This question tests foundational knowledge of pharmacologic therapy used to induce ovulation in PCOS, which is primarily a reproductive endocrinology/infertility topic rather than a nursing care intervention scenario.

Question 17

Which test evaluates male fertility fastest?

Accepted Answer

Answer reason: Semen analysis is the first-line and quickest standard test to evaluate male fertility because it directly measures key fertility parameters (sperm concentration, motility, morphology, volume) from an easily obtained sample. Testicular biopsy is invasive and typically reserved for evaluating azoospermia or obstruction after initial workup. Hormone assays help identify endocrine causes but do not directly assess functional sperm output. Sperm DNA testing is specialized and not the fastest initial screening test.
Category reason: The question tests foundational evaluation of male reproductive function and infertility testing (what test is used first/fastest), which is core Reproductive System science rather than a nursing care decision.

Question 18

What is the primary function of the testes in the male reproductive system?

Accepted Answer

Answer reason: The testes have two primary functions: spermatogenesis (production of sperm in the seminiferous tubules) and secretion of testosterone by Leydig cells. Sperm storage and maturation primarily occur in the epididymis, not the testes. Transport of sperm to the urethra is mainly via the vas deferens and ejaculatory ducts, and seminal fluid is produced by accessory glands (seminal vesicles, prostate, bulbourethral glands).
Category reason: This question tests foundational knowledge of male reproductive organ function (testes) rather than nursing interventions or clinical decision-making, so it fits the Reproductive System in NursingScience.

Question 19

Which condition is known as the chocolate cyst of the ovary?

Accepted Answer

Answer reason: A “chocolate cyst” refers to an ovarian endometrioma, which is a manifestation of endometriosis involving the ovary. These cysts contain thick, dark, old blood from repeated cyclical bleeding of ectopic endometrial tissue, giving the classic chocolate-brown appearance. Functional ovarian cysts such as follicular and corpus luteum cysts do not characteristically contain this old blood debris. Theca lutein cysts are typically associated with high hCG states and are not called chocolate cysts.
Category reason: The question tests recognition of a gynecologic disease entity (ovarian endometrioma) and its classic terminology, which is foundational knowledge within the Reproductive System.

Question 20

Before the women give birth, the OS (Cervix) Require ___ cm?

Accepted Answer

Answer reason: For vaginal birth, the cervix must be fully dilated to allow passage of the fetal head, which is conventionally 10 cm. Clinically, many references describe full dilation as 10 cm, and the option that best matches this standard is "8 to 10 cm" (with 10 cm being the target). The other options (8 cm and 14 cm) are not considered full dilation for second-stage labor.
Category reason: The question tests factual knowledge about cervical dilation (full dilation in labor), which is a foundational obstetric concept within the Reproductive System rather than a nursing intervention or prioritization scenario.

Question 21

Which environmental factor reduces male sperm motility most?

Accepted Answer

Answer reason: Elevated scrotal/testicular temperature is a well-established, direct cause of reduced sperm quality, particularly decreased motility, because spermatogenesis and sperm function require temperatures a few degrees below core body temperature. Heat exposure from frequent hot baths/saunas, tight clothing, or occupational heat can impair mitochondrial function and increase oxidative stress in sperm, lowering motility. While smoking, alcohol, and radiation can also negatively affect fertility, heat has the most immediate and consistently demonstrable impact on motility in typical environmental exposures.
Category reason: The question tests factors affecting sperm function and fertility (motility) rather than nursing interventions or prioritization, which is core content within the Reproductive System.

Question 22

What is the most common cause of male infertility?

Accepted Answer

Answer reason: Varicocele is the most common correctable cause of male infertility and is commonly associated with abnormal semen parameters due to increased scrotal temperature and impaired testicular function. It can reduce sperm count, motility, and morphology. Azoospermia and oligospermia describe semen analysis findings rather than a single etiologic condition, and testicular torsion is an acute emergency that is not the most common cause of infertility overall.
Category reason: This item tests foundational knowledge of causes of male infertility within the male reproductive system rather than nursing interventions or clinical prioritization, so it fits NursingScience under the Reproductive System.

Question 23

Which factor most affects IVF success?

Accepted Answer

Answer reason: The single strongest predictor of IVF success is the female partner’s age because oocyte quantity and, more importantly, oocyte/embryo chromosomal normality decline with advancing age. This drives lower implantation rates and higher miscarriage rates even when sperm parameters and endometrial thickness are acceptable. Embryo quality is important, but it is largely determined by oocyte quality, which is age-dependent. Therefore, female age most affects overall IVF outcomes.
Category reason: This item tests foundational reproductive medicine knowledge about determinants of IVF outcomes (ovarian reserve and oocyte quality with aging), rather than nursing interventions or clinical prioritization, so it fits NursingScience under the Reproductive System.

Question 24

The mammalian organ through which nourishment diffuse into an embryo is?

Accepted Answer

Answer reason: The placenta is the organ that mediates exchange of oxygen, nutrients, and wastes between maternal and fetal blood via diffusion and active transport across the placental membrane. The chorion forms part of the fetal membranes and contributes to placental formation (chorionic villi) but is not typically considered the organ of nutrient exchange by itself in this context. The amnion mainly encloses amniotic fluid for protection, and the umbilical cord is the conduit carrying fetal blood to and from the placenta rather than the site of diffusion.
Category reason: This is a foundational question about fetal membranes/placental physiology and maternal-fetal exchange, which is core reproductive biology rather than nursing intervention or clinical judgment.

Question 25

Q. The external female genitalia are collectively known as the?

Accepted Answer

Answer reason: The vulva is the collective term for the external female genital structures, including the mons pubis, labia majora/minora, clitoris, and vestibule. In contrast, the fallopian tubes and ovaries are internal reproductive organs. The vagina is an internal muscular canal, not the overall term for external genitalia. Therefore, the best answer is vulva.
Category reason: This is a foundational anatomy terminology question about female external genital structures, which falls under the Reproductive System.

Question 26

Failure of the testes to descend into the scrotum is called ____?

Accepted Answer

Answer reason: Failure of one or both testes to descend into the scrotum is termed cryptorchidism (undescended testis). This is a common congenital condition and is clinically important because persistent cryptorchidism is associated with impaired fertility and increased risk of testicular malignancy. The other options are unrelated anatomic terms and do not describe testicular descent failure.
Category reason: The question tests knowledge of a male reproductive developmental condition (undescended testes), which is foundational content in the Reproductive System subject rather than nursing interventions or prioritization.

Question 27

A woman presents with lower abdominal pain, vaginal discharge, and fever. What is the most likely diagnosis?

Accepted Answer

Answer reason: Lower abdominal (pelvic) pain with abnormal vaginal discharge and fever is most consistent with pelvic inflammatory disease due to ascending infection of the upper genital tract (e.g., endometritis/salpingitis). Endometriosis typically causes chronic cyclic pelvic pain and dyspareunia rather than fever and purulent discharge. Ovarian cyst rupture usually presents with sudden unilateral pain without infectious discharge/fever. Ectopic pregnancy commonly causes amenorrhea with pain and possible vaginal bleeding, not purulent discharge and fever.
Category reason: The question tests recognizing the most likely gynecologic diagnosis from a symptom cluster (pelvic pain, discharge, fever), which is foundational disease identification within the Reproductive System rather than nursing interventions or prioritization.

Question 28

What prevents more than one sperm from entering an ovum?

Accepted Answer

Answer reason: The zona pellucida is the glycoprotein layer around the oocyte that mediates sperm binding and, after the first sperm fuses with the oocyte, undergoes the zona reaction (hardening) to block polyspermy. Cortical granule exocytosis modifies zona pellucida receptors so additional sperm cannot penetrate. Placenta forms after implantation, and the cervix and uterus are parts of the female reproductive tract but do not provide the immediate block to multiple sperm entering the ovum.
Category reason: This question tests the biological mechanism that prevents polyspermy during fertilization, a core concept of human reproduction rather than a nursing care action, so it fits the Reproductive System subject in NursingScience.

Question 29

A Rh-negative mother delivers a Rh-positive baby. When should Rh immunoglobulin (Rhogam) be administered?

Accepted Answer

Answer reason: Rho(D) immune globulin should be given to an Rh-negative mother after delivering an Rh-positive infant to prevent maternal sensitization to the D antigen. The optimal timing is within 72 hours postpartum, when fetomaternal hemorrhage from delivery may expose maternal circulation to fetal Rh-positive red cells. Giving it only in a later pregnancy is too late because sensitization can occur with the current delivery. Newborn jaundice relates to hemolytic disease in the infant and is not the indication/timing for administering Rhogam to the mother.
Category reason: This question tests foundational obstetric/immunohematologic knowledge about Rh incompatibility prophylaxis (timing of Rho(D) immune globulin after delivery), which fits best under the Reproductive System rather than nursing-priority decision-making.

Question 30

A woman at 30 weeks with polyhydramnios is at risk for which complication?

Accepted Answer

Answer reason: Polyhydramnios overdistends the uterus, increasing uterine irritability and the likelihood of preterm labor. When membranes rupture, the excess fluid can cause a sudden gush that may wash the umbilical cord downward, leading to cord prolapse—especially if the presenting part is not well engaged. This is a classic obstetric complication of polyhydramnios and is more directly associated than prolonged pregnancy, fetal growth restriction, or uterine rupture.
Category reason: The question tests an obstetric complication of a pregnancy condition (polyhydramnios) and its pathophysiologic consequences (uterine overdistension, malpresentation, cord prolapse), which is foundational reproductive-system knowledge rather than a nursing management/prioritization item.

Question 31

A pregnant woman at 32 weeks gestation visits the clinic for a routine check-up. She reports dizziness and lightheadedness when lying flat on her back. What is the most likely cause of her symptoms?

Accepted Answer

Answer reason: At ~32 weeks, the gravid uterus can compress the inferior vena cava when the patient lies supine, reducing venous return to the heart and lowering cardiac output, which causes dizziness and lightheadedness. This is classic supine hypotensive syndrome and typically improves with left lateral positioning to relieve vena cava compression. Hypoglycemia is not specifically triggered by supine positioning, hyperemesis gravidarum is an early-pregnancy condition with severe vomiting, and pre-eclampsia is characterized by hypertension and end-organ findings rather than positional symptoms.
Category reason: The question tests a pregnancy-related physiologic mechanism (vena cava compression and decreased venous return) rather than nursing prioritization or intervention selection, so it fits foundational reproductive physiology.

Question 32

Which test is used to confirm pregnancy?

Accepted Answer

Answer reason: Pregnancy is confirmed by detecting human chorionic gonadotropin (hCG), a hormone produced after implantation. A urine hCG test is the standard, widely used test to confirm pregnancy and can become positive shortly after a missed period. Ultrasound is used to visualize and date an intrauterine pregnancy and assess viability, but it is not the primary confirmatory test at the earliest stage. X-ray does not diagnose pregnancy and is generally avoided due to fetal radiation risk.
Category reason: This item tests foundational knowledge of how pregnancy is confirmed (hCG hormone detection), which is part of reproductive physiology and basic diagnostics rather than a nursing management decision.

Question 33

Uterus is single and it is also called?

Accepted Answer

Answer reason: The uterus is commonly referred to as the womb, the organ where implantation occurs and where a fetus develops during pregnancy. The other options are different anatomical structures: the cervical canal is part of the cervix, the mons pubis is external genital tissue, and the ampulla refers to a dilated portion of a tube (commonly the fallopian tube). Therefore, "womb" is the correct synonym for uterus.
Category reason: This question tests basic anatomical terminology of female reproductive organs (what the uterus is also called), which is foundational reproductive system knowledge rather than a nursing care decision.

Question 34

Post-menopausal woman 50-year-old woman is on hormone replacement therapy her sister died of Breast cancer in middle age She is at risk of?

Accepted Answer

Answer reason: A postmenopausal woman on hormone replacement therapy (particularly combined estrogen-progestin therapy, and longer duration of use) has an increased risk of breast cancer. In addition, a first-degree family history (sister with premenopausal/middle-age breast cancer) increases baseline risk, making breast carcinoma the most likely cancer risk highlighted by the stem. Endometrial cancer risk is classically increased with unopposed estrogen, but the question emphasizes HRT plus strong family history of breast cancer. Therefore, breast carcinoma is the single best answer among the options.
Category reason: The item tests biomedical knowledge about how hormone replacement therapy and family history affect cancer risk in the female reproductive/breast system, which is foundational Reproductive System content rather than a nursing-intervention decision.

Question 35

43 year old lady with 3 children and normal reproductive cycle, has less chance of pregnancy as compared to 33 yr old female, reason is?

Accepted Answer

Answer reason: Female fertility declines with advancing age primarily due to reduced ovarian reserve and decline in oocyte quality (increased aneuploidy), leading to lower fecundability and higher miscarriage risk even with apparently normal cycles. This is not best explained by inhibition of GnRH, lactation, or a consistently low LH surge in a regularly cycling 43-year-old. Therefore, among the provided options, the most correct choice is that none of the listed mechanisms accounts for the age-related decline.
Category reason: The question tests a foundational concept of age-related fertility decline and ovarian function, which is core content in the Reproductive System rather than a nursing care/intervention scenario.

Question 36

The absence of sperm in the semen ....

Accepted Answer

Answer reason: Azoospermia specifically means complete absence of spermatozoa in the ejaculate on semen analysis. Oligospermia refers to a decreased sperm count, not total absence. Hemospermia indicates blood in semen and does not describe sperm quantity. Therefore, the correct term for absence of sperm in semen is azoospermia.
Category reason: This is a terminology/concept question about male fertility and semen findings, which is core content of the Reproductive System in nursing science rather than a nursing-intervention scenario.

Question 37

Excessive Menstrual bleeding is called?

Accepted Answer

Answer reason: Menorrhagia is the medical term for abnormally heavy or prolonged menstrual bleeding. Amenorrhea refers to absent menstruation, not excessive bleeding. Dysmenorrhoea refers to painful menstruation (cramps), which can occur with normal or abnormal flow but does not mean heavy bleeding. Therefore, the best answer is menorrhagia.
Category reason: This item tests medical terminology related to menstrual disorders and uterine bleeding patterns, a foundational concept within the Reproductive System.

Question 38

Female gamete is called ?

Accepted Answer

Answer reason: The female gamete is the ovum (egg cell), produced in the ovaries and carrying a haploid set of chromosomes. Sperm is the male gamete. A zygote forms after fertilization when sperm and ovum fuse, and an embryo is a later developmental stage after multiple cell divisions.
Category reason: This item tests basic reproductive biology terminology (identifying the female gamete), which belongs to the Reproductive System within Nursing Science rather than nursing care decision-making.

Question 39

What is the average length of a full-term pregnancy?

Accepted Answer

Answer reason: A full-term pregnancy is typically dated as 40 weeks of gestational age, counted from the first day of the last menstrual period. While “term” can span 37–42 weeks, the average/standard estimate used clinically (e.g., Naegele’s rule for EDD) is 40 weeks. Therefore, 40 weeks is the best answer among the options provided.
Category reason: The question tests foundational knowledge of human gestation duration, which is a core concept in reproductive physiology/obstetrics rather than a nursing care decision.

Question 40

What is the most common cause of postpartum hemorrhage?

Accepted Answer

Answer reason: Uterine atony is the most common cause of postpartum hemorrhage because failure of the uterus to contract effectively leaves the uterine spiral arteries at the placental site open, leading to heavy bleeding. It corresponds to the primary “Tone” component of the classic “4 T’s” (Tone, Tissue, Trauma, Thrombin) causes of postpartum hemorrhage. Retained placental tissue, genital tract trauma, and coagulopathy are important causes but occur less frequently than uterine atony overall.
Category reason: The item tests the underlying etiology/pathophysiology of postpartum hemorrhage (the most common cause), which is foundational obstetric knowledge rather than a nursing intervention or prioritization scenario, fitting the Reproductive System domain.

Question 41

Which age range shows maximum decline in female fertility?

Accepted Answer

Answer reason: Female fertility begins to decline gradually after about age 30 but the decline becomes much steeper after age 35 due to decreasing ovarian reserve and oocyte quality. The 35–39 age band is classically taught as the period where the most noticeable/maximum decline starts and accelerates. By 40–44 fertility is already markedly reduced, but the key inflection point for the sharp decline is typically 35–39.
Category reason: The question tests age-related changes in reproductive capacity (ovarian reserve and fertility decline), which is foundational content of the Reproductive System rather than a nursing intervention/priority scenario.

Question 42

What stage is the placenta delivered at?

Accepted Answer

Answer reason: Labor is classically divided into stages: the first stage is cervical dilation, the second stage is delivery of the fetus, and the third stage is delivery of the placenta (afterbirth). Placental separation and expulsion occur after the baby is born, accompanied by uterine contraction to reduce postpartum bleeding. Therefore, the placenta is delivered in the third stage of labor.
Category reason: The question tests factual knowledge about the stages of labor and when the placenta is expelled, which is foundational obstetric content within the Reproductive System rather than a nursing judgment or intervention scenario.

Question 43

Fertilization occurs in?

Accepted Answer

Answer reason: In humans, fertilization most commonly occurs in the ampulla, the widest portion of the fallopian (uterine) tube where sperm and ovum are most likely to meet. After fertilization, the resulting zygote travels toward the uterus for implantation. The fimbrial end helps capture the ovulated oocyte, and the isthmus is narrower and mainly serves as a passageway, not the usual fertilization site.
Category reason: The item tests where fertilization occurs within female reproductive anatomy (fallopian tube segments), which is foundational reproductive system knowledge rather than a nursing care decision.

Question 44

How many chromosomes do the mature ovum contain...?

Accepted Answer

Answer reason: A mature ovum is a haploid gamete produced by meiosis, so it contains one set of chromosomes (n). In humans, the haploid number is 23 chromosomes, not 23 pairs. Having 46 chromosomes (diploid) would describe a somatic cell or the zygote after fertilization. Therefore the best answer is 23 single.
Category reason: The question tests foundational reproductive biology/genetics of human gametes (haploid vs diploid chromosome number), which fits NursingScience under the Reproductive System.

Question 45

The fallopian tubes are also called –?

Accepted Answer

Answer reason: Fallopian tubes are anatomically synonymous with oviducts, the paired tubular structures that receive the ovum after ovulation and are the usual site of fertilization (most commonly the ampulla). The term “uterine tubes” is also used, but among the given options, “oviducts” is the correct equivalent. “Cervical canals” and “vagina” are distinct reproductive structures and are not alternate names for the fallopian tubes.
Category reason: This is a foundational anatomy/terminology question about female reproductive tract structures and their alternate names, which fits the Reproductive System subject rather than a nursing care decision.

Question 46

INVESTIGATION FOR SUSPECTED ECTOPIC PREGNANCY?

Accepted Answer

Answer reason: Quantitative serum β-hCG is a key initial investigation when ectopic pregnancy is suspected because abnormal rise (slower-than-expected doubling) supports a nonviable or ectopic gestation. Interpreting β-hCG trends alongside early pelvic ultrasound helps determine whether an intrauterine pregnancy should be visible at the discriminatory zone. Pelvic MRI is not a first-line test, laparoscopy is invasive and generally reserved when diagnosis remains unclear or for treatment, and endometrial biopsy is not used to diagnose ectopic pregnancy.
Category reason: This question tests diagnostic evaluation of a pregnancy-related condition (ectopic pregnancy) rather than nursing interventions or prioritization, fitting foundational knowledge of the Reproductive System.

Question 47

Birth control methods are called?

Accepted Answer

Answer reason: Birth control refers broadly to methods used to prevent pregnancy, which is termed contraception. Sterilization is only one type of contraception (a permanent method), not the umbrella term for all birth control methods. Immunization prevents infectious diseases, and ovulation is a physiologic process of egg release, not a pregnancy-prevention method.
Category reason: This question tests foundational terminology about preventing pregnancy, which is a core concept within the Reproductive System rather than nursing decision-making or patient-care prioritization.

Question 48

The 1st menstruation in a female is called as-?

Accepted Answer

Answer reason: Menarche is the term for the first menstrual period, marking the onset of menstruation and reproductive maturity in puberty. Menopause refers to the permanent cessation of menstruation, typically in midlife. Dysmenorrhea means painful menstruation, and amenorrhea means absence of menstruation. Therefore, the first menstruation is called menarche.
Category reason: This item tests terminology and concepts related to female reproductive development (onset of menstruation), which falls under the Reproductive System in Nursing Science.

Question 49

During ejaculation, which gland contributes the majority of the seminal fluid volume?

Accepted Answer

Answer reason: The seminal vesicles produce the largest portion of semen volume (about 60–70%), supplying fructose and other substances that support sperm motility and viability. The prostate contributes a smaller fraction (about 20–30%) with enzymes such as PSA that aid semen liquefaction. Cowper’s (bulbourethral) glands and urethral glands mainly secrete small amounts of lubricating/alkaline mucus (pre-ejaculate) and do not account for most seminal volume.
Category reason: This is a foundational question about which male accessory reproductive gland produces most of the seminal fluid, which falls under reproductive system anatomy/physiology rather than nursing care decision-making.

Question 50

Amniotic fluid volume during pregnancy is-?

Accepted Answer

Answer reason: Amniotic fluid volume increases throughout pregnancy and typically reaches about 800–1000 mL near term (around 36–38 weeks) before slightly decreasing post-term. Therefore, the best matching option for the usual near-term amniotic fluid volume is 700–1000 mL. Option C uses grams (mass) rather than milliliters (volume) and is not the standard way this is reported. Option A is lower than the typical peak/term range cited in obstetrics references.
Category reason: The item tests normal pregnancy physiology (typical amniotic fluid volume ranges) rather than a nursing intervention or prioritization, so it fits foundational reproductive science.
