Reproductive System Exam Questions

1. Where does fertilization normally occur?

A. Ampulla
B. Interstitial portion
C. Isthmus
D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

2. Which female reproductive organ is positioned directly posterior to the bladder?

A. Uterine tube
B. Vagina
C. Uterus
D. Ovaries

Correct answer: C

Rationale: The correct answer is the uterus. The uterus is positioned directly posterior to the bladder in the female reproductive system. The uterine tube (choice A) is also known as the fallopian tube, which is not positioned directly posterior to the bladder. The vagina (choice B) is located below the uterus and not directly posterior to the bladder. The ovaries (choice D) are located on either side of the uterus, but they are not positioned directly posterior to the bladder.

3. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
B. Blood volume and plasma volume decrease, and red blood cells decrease.
C. No changes occur in the haematological system during pregnancy.
D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.

4. What is a characteristic of threatening abortion?

A. Os open.
B. Firm contracted uterus.
C. Heavy bleeding.
D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

5. What is a Carneous Mole defined as?

A. Occurs when fluids drain from the blood mole, leaving a fresh firm mass.
B. Occurs when the ovum dies and is expelled.
C. Occurs when the fetus dies, and the membranes rupture.
D. Occurs when the fetus survives after a failed abortion attempt.

Correct answer: A

Rationale: A Carneous Mole is defined as when fluids drain from the blood mole, leaving a fresh firm mass. This process leads to the formation of a solid mass resembling tissue. Choice B is incorrect as it describes a different concept known as a missed abortion, where the ovum dies and is expelled. Choice C is incorrect as it describes a situation related to fetal demise and membrane rupture, not specifically the formation of a Carneous Mole. Choice D is incorrect as it refers to a scenario where the fetus survives after a failed abortion attempt, which is distinct from the definition of a Carneous Mole.
