- A.
Ovaries
- B.
Vagina
- C.
Uterus
- D.
Fallopian Tubes
Correct Answer
D. Fallopian TubesExplanation
Fertilization occurs in the fallopian tubes. This is where the sperm and egg meet and combine to form a fertilized egg, also known as a zygote. The fallopian tubes provide a pathway for the egg to travel from the ovaries to the uterus.Rate this question:

Which of the following terms correspond with the phrase: a woman that is pregnant?
- A.
Gravida
- B.
Parity
- C.
Spermatogonia
- D.
Zona pellucida
Correct Answer
A. GravidaExplanation
The term "gravida" refers to a woman who is pregnant. It is a medical term used to describe the number of times a woman has been pregnant, regardless of the outcome (whether the pregnancies resulted in live births, stillbirths, or abortions). It does not take into account the duration of the pregnancies or the number of fetuses. Therefore, "gravida" is the correct term that corresponds with the phrase "a woman that is pregnant."Rate this question:

Which of the following sign's may indicate pregnancy?
- A.
Chadwick's sign
- B.
Turner's sign
- C.
Virchow's sign
- D.
Kock's sign
Correct Answer
A. Chadwick's signExplanation
Chadwick's sign is a bluish discoloration of the cervix, vagina, and vulva that can occur during pregnancy. This is caused by increased blood flow to the area due to hormonal changes. Turner's sign refers to the presence of a bluish color in the flank area, which is not related to pregnancy. Virchow's sign refers to the presence of enlarged and palpable lymph nodes in the supraclavicular area, which is not specific to pregnancy. Kock's sign is not a recognized sign of pregnancy. Therefore, the presence of Chadwick's sign is the most likely indication of pregnancy among the given options.Rate this question:

Which of the following is not an associated change during the antepartum period?
- A.
Increased urination frequency
- B.
Increased respiratory requirements
- C.
Decreased basal metabolic rate
- D.
Goodell's sign
Correct Answer
C. Decreased basal metabolic rateExplanation
During the antepartum period, the body undergoes various changes to accommodate the growing fetus. Increased urination frequency is a common change due to increased blood flow to the kidneys. Increased respiratory requirements occur as the body needs to supply oxygen to both the mother and the fetus. Goodell's sign refers to the softening of the cervix. However, the basal metabolic rate actually increases during pregnancy to support the increased energy needs of the mother and the fetus. Therefore, the correct answer is that decreased basal metabolic rate is not an associated change during the antepartum period.Rate this question:

Which of the following matches the definition: abnormal placenta development covering the cervix?
- A.
Placenta Previa
- B.
Abruptio Placentae
- C.
Multigravida
- D.
Proliferative phase
Correct Answer
A. Placenta PreviaExplanation
Placenta Previa is the correct answer because it refers to the abnormal development of the placenta covering the cervix. This condition can cause bleeding during pregnancy and may require a cesarean section for delivery. Abruptio Placentae refers to the premature separation of the placenta from the uterus, Multigravida refers to a woman who has been pregnant more than once, and Proliferative phase refers to a stage of the menstrual cycle.Rate this question:

Which of the following is not scored with the APGAR?
- A.
0
- B.
Heart Rate
- C.
Color
- D.
Tone
Correct Answer
A. 0Explanation
The APGAR score is a test used to assess the health of a newborn baby immediately after birth. It evaluates five factors: heart rate, respiratory effort, muscle tone, reflex irritability, and color. However, the number "0" is not a factor that is scored with the APGAR. The APGAR score ranges from 0 to 10, with a higher score indicating better health.Rate this question:

Which of these is not considered a T.O.R.C.H. infection?
- A.
Rubella
- B.
Herpes
- C.
Cytomegalovirus
- D.
Croup
Correct Answer
D. CroupExplanation
Croup is not considered a T.O.R.C.H. infection because T.O.R.C.H. stands for a group of infections that can be transmitted from mother to fetus during pregnancy, and Croup is not caused by any of the pathogens associated with T.O.R.C.H. infections. Croup is a viral infection that affects the upper airway and causes inflammation, leading to symptoms like coughing, hoarseness, and difficulty breathing. It is commonly caused by the parainfluenza virus and is not related to T.O.R.C.H. infections such as Rubella, Herpes, or Cytomegalovirus.Rate this question:

Which of the following develops into the ejaculatory duct and ductus deferens?
- A.
Paramesonephric duct
- B.
Mesonephric duct
- C.
Sympathetic duct
- D.
Parasympathetic duct
Correct Answer
B. Mesonephric ductExplanation
The correct answer is the mesonephric duct. During embryonic development, the mesonephric duct forms in males and gives rise to the ejaculatory duct and ductus deferens, which are important structures in the male reproductive system. The paramesonephric duct, on the other hand, develops into the female reproductive structures. The sympathetic and parasympathetic ducts are not involved in the development of the ejaculatory duct and ductus deferens.Rate this question:

Which of the following is the result of poor fusion between the paramesonephric ducts in females?
- A.
Placenta Previa
- B.
Bicornuate uterus
- C.
Multigravida
- D.
Proliferative phase
Correct Answer
B. Bicornuate uterusExplanation
The result of poor fusion between the paramesonephric ducts in females is a bicornuate uterus. The paramesonephric ducts are embryonic structures that give rise to the female reproductive system, including the uterus. If there is incomplete fusion of these ducts, it can lead to the formation of a bicornuate uterus, which is characterized by a heart-shaped uterus with a deep indentation in the middle. This condition can affect fertility and increase the risk of complications during pregnancy.Rate this question:

Where does spermatogenesis occur?
- A.
Seminiferous tubules
- B.
Corpus spongiosoma
- C.
Prostate gland
- D.
Scrotum
Correct Answer
A. Seminiferous tubulesExplanation
Spermatogenesis, the process of sperm production, occurs in the seminiferous tubules. These tubules are located within the testes, which are the male reproductive organs. The seminiferous tubules are responsible for the production and maturation of sperm cells. They are lined with specialized cells called Sertoli cells, which support and nourish the developing sperm cells. The other options listed, such as the corpus spongiosum, prostate gland, and scrotum, are not directly involved in spermatogenesis.Rate this question:

The tip of the sperm is called the ____.
- A.
Head
- B.
Acrosome
- C.
Tail
- D.
Nucleus
Correct Answer
B. AcrosomeExplanation
The acrosome is a structure located at the tip of the sperm. It contains enzymes that are essential for the sperm to penetrate and fertilize the egg. The head of the sperm contains the nucleus, which carries the genetic material, but the acrosome is specifically responsible for aiding in the fertilization process. The tail of the sperm, also known as the flagellum, helps the sperm to swim towards the egg. Therefore, the correct answer is acrosome.Rate this question:

Which of the following develops into: bone, connective tissue, blood, and the spleen?
- A.
Notochord
- B.
Endoderm
- C.
Mesoderm
- D.
Ectoderm
Correct Answer
C. MesodermExplanation
Mesoderm is the correct answer because it is one of the three primary germ layers in the developing embryo. It gives rise to various tissues and organs including bone, connective tissue, blood, and the spleen. The mesoderm layer is responsible for the formation of the musculoskeletal system, circulatory system, and several other structures in the body.Rate this question:

Which of the following is not a germ layer during the 3rd week of development?
- A.
Mesoderm
- B.
Ectoderm
- C.
Endoderm
- D.
Exoderm
Correct Answer
D. ExodermExplanation
During the 3rd week of development, the three primary germ layers that form in the early embryo are the ectoderm, mesoderm, and endoderm. These germ layers give rise to different tissues and organs in the body. However, "exoderm" is not a recognized germ layer during this stage of development. It is likely a distractor option that is not relevant to embryonic development.Rate this question:

The umbilical vein carries _____ blood.
- A.
Deoxygenated
- B.
Oxygenated
Correct Answer
B. OxygenatedExplanation
The umbilical vein carries oxygenated blood. This is because the umbilical vein connects the fetus to the placenta, where oxygen and nutrients are exchanged between the mother's blood and the fetus's blood. Oxygenated blood from the placenta is then carried back to the fetus through the umbilical vein, providing oxygen and nutrients for the developing fetus.Rate this question:

Ovulation occurs during which of the following phases?
- A.
Menstrual
- B.
Secretory
- C.
Proliferative
- D.
Follicle
Correct Answer
C. ProliferativeExplanation
During the proliferative phase, the lining of the uterus thickens in preparation for a potential pregnancy. This phase occurs after menstruation and before ovulation. Ovulation itself occurs during the follicular phase, when a mature egg is released from the ovary. The secretory phase follows ovulation and is characterized by the thickening of the uterine lining and the production of progesterone. Therefore, the correct answer is proliferative.Rate this question:

Following fertilization the blastocyst secrets a hormone called?
- A.
Human Chorionic Gonadotropin
- B.
Oxytocin
- C.
FSH
- D.
LH
Correct Answer
A. Human Chorionic GonadotropinExplanation
After fertilization, the blastocyst secretes a hormone called Human Chorionic Gonadotropin (HCG). HCG is produced by the developing placenta and plays a crucial role in maintaining pregnancy. It helps to support the corpus luteum in the ovary, which continues to produce progesterone and estrogen to sustain the pregnancy. HCG is also the hormone detected in pregnancy tests.Rate this question:

Progesterone is secreted from a female's _____ to help the implanted embryo and continue the pregnancy.
- A.
Corpus luteum
- B.
Mesoderm
- C.
Endoderm
- D.
Thyroid
Correct Answer
A. Corpus luteumExplanation
Progesterone is secreted from a female's corpus luteum to help the implanted embryo and continue the pregnancy. The corpus luteum is a temporary gland that forms in the ovary after ovulation. It produces progesterone, which is essential for the maintenance of the uterine lining and the development of the embryo. Without sufficient levels of progesterone, the uterine lining may shed, leading to the termination of pregnancy. Therefore, the corpus luteum plays a crucial role in supporting early pregnancy by secreting progesterone.Rate this question:

Which of the following is not appropriately matched with the term: Braxton Hicks contractions?
- A.
Painless
- B.
Intermittent contractions
- C.
Edema
- D.
Irregular
Correct Answer
C. EdemaExplanation
Braxton Hicks contractions are a normal part of pregnancy, characterized by painless, intermittent, and irregular contractions. Edema, on the other hand, refers to the swelling caused by excess fluid in the body's tissues, which is not related to contractions. Therefore, edema is not appropriately matched with the term Braxton Hicks contractions.Rate this question:

If a newborn exhibits a heart rate of 80 bpm the APGAR score should be?
- A.
0
- B.
1
- C.
2
- D.
3
Correct Answer
B. 1Explanation
A newborn with a heart rate of 80 bpm would receive an APGAR score of 1. The APGAR score is a quick assessment tool used to evaluate the overall health and well-being of a newborn immediately after birth. It evaluates five factors: Appearance, Pulse, Grimace, Activity, and Respiration. Each factor is assigned a score of 0, 1, or 2, with a maximum total score of 10. A heart rate of 80 bpm would fall under the category of a moderately low pulse, which corresponds to a score of 1 on the APGAR scale.Rate this question:

If a newborn exhibits blue extremities and the body is pink the APGAR score should be?
- A.
0
- B.
1
- C.
2
- D.
3
Correct Answer
B. 1Explanation
A newborn exhibiting blue extremities and a pink body indicates that the baby may be experiencing some difficulty in breathing or circulation. This condition is known as acrocyanosis. A score of 1 on the APGAR scale is given when the baby has a slightly bluish color in the extremities but a pink body. This score suggests that the baby may require some medical attention and monitoring to ensure proper breathing and circulation.Rate this question:
