Each breast is situated on each side of the sternum and extends between the:
- A. 1st and 6th rib
- B. 2nd and 6th rib
- C. 3rd and 6th rib
- D. 4th and 6th rib
Correct Answer: B
Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.

What is amniocentesis used to detect?
- A. Sexually transmitted diseases
- B. Presence of certain genetic disorders
- C. Causes of infertility
- D. Presence of pneumonia germs
Correct Answer: B
Rationale: Amniocentesis is a prenatal test used to detect certain genetic disorders in a developing fetus. It involves collecting a small sample of the amniotic fluid surrounding the fetus and analyzing the genetic material present in the cells. This test is not used to detect sexually transmitted diseases, causes of infertility, or the presence of pneumonia germs. Therefore, the correct answer is B.
Outlet of the true pelvis anteriorly bounded by:
- A. Ischiopubic arch (T)
- B. Linea terminalis (F)
- C. Coccyx (T)
- D. Promontory of the sacrum (F)
Correct Answer: A
Rationale: The correct answer is A: Ischiopubic arch. The outlet of the true pelvis is indeed anteriorly bounded by the ischiopubic arch, which consists of the ischium and the pubic bones. This structure forms the lower boundary of the pelvic outlet. The other choices, B, C, and D, are incorrect. The linea terminalis (pelvic brim) forms the upper boundary of the true pelvis, the coccyx is part of the bony pelvis but does not bound the pelvic outlet anteriorly, and the promontory of the sacrum is located in the posterior part of the pelvis, not the anterior boundary of the pelvic outlet.
What should be included in the differential diagnosis of ectopic pregnancy?
- A. Inevitable abortion
- B. Dysmenorrhea
- C. Twisted ovarian cyst
- D. Fibroids
Correct Answer: C
Rationale: In the differential diagnosis of ectopic pregnancy, conditions such as twisted ovarian cysts should be considered. Twisted ovarian cysts can present with similar symptoms to ectopic pregnancy, making it important to include them in the differential diagnosis. Choices A, B, and D are not typically part of the differential diagnosis of ectopic pregnancy. Inevitable abortion refers to an imminent miscarriage, dysmenorrhea is characterized by painful menstruation, and fibroids are benign growths in the uterus, none of which are directly related to ectopic pregnancy.
Which of the following are outcomes of an ectopic pregnancy EXCEPT?
- A. Tubal abortion
- B. Tubal rupture
- C. Intra-tubal bleeding
- D. Secondary abdominal pregnancy
Correct Answer: D
Rationale: Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. Common outcomes include tubal abortion (spontaneous termination of ectopic pregnancy within the fallopian tube), tubal rupture (rupture of the fallopian tube leading to internal bleeding), and intra-tubal bleeding. Secondary abdominal pregnancy, on the other hand, is a rare occurrence and not a typical outcome of an ectopic pregnancy. It involves the implantation of a fertilized egg in the peritoneal cavity rather than the uterus.
What does the umbilical cord contain?
- A. Pluripotent stem cells
- B. Cord blood stem cells
- C. Blood stem cells
- D. None of the above
Correct Answer: B
Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.
