The following take part in the fecundation process:

  • A. a single ovule;
  • B. a single fecundated spermatozoon;
  • C. one ovule with two nuclei, which means the pregnancy is monovitelline twin;
  • D. two ovules, which means the pregnancy is bivitelline twin;
Correct Answer: C

Rationale: The correct answer is C, one ovule with two nuclei, which means the pregnancy is monovitelline twin. This is correct because during fertilization, a single sperm fertilizes an ovum, resulting in the formation of a zygote with two nuclei. Monovitelline twins originate from the splitting of a single fertilized egg, leading to two embryos with shared genetic material. The other choices, A and B, are incorrect as they do not accurately represent the process of fecundation. Choice A refers to a single ovule before fertilization, and choice B refers to a single spermatozoon, which is involved in fertilization but does not lead to the formation of twins. Choice D is also incorrect as it describes bivitelline twins, which result from the fertilization of two separate eggs by two different sperm, leading to genetically distinct individuals.

The fingerlike ends of fallopian tubes are called as:

  • A. Cilia
  • B. Papillae
  • C. Flagellae
  • D. Fimbriae
Correct Answer: D

Rationale: The correct answer is D: Fimbriae. Fimbriae are the fingerlike projections at the end of the fallopian tubes that help capture the released egg from the ovary. They create a sweeping motion to guide the egg into the tube for fertilization. Cilia (A) are hair-like projections that help with movement, but they are not specific to the fallopian tubes. Papillae (B) are small, raised projections found in various organs, not in the fallopian tubes. Flagellae (C) are whip-like structures used for movement in some cells, not found in the fallopian tubes. In summary, fimbriae are specifically designed to capture and guide the egg, making them the correct choice.

Arterial supply of breast include

  • A. Internal thoracic artery
  • B. Thoracoaromial artery
  • C. Superior epigastric artery
  • D. Common carotid artery
Correct Answer: A

Rationale: The correct answer is A: Internal thoracic artery. The internal thoracic artery is a major branch of the subclavian artery and supplies the breast tissue. It gives rise to the perforating branches that supply the breast. The other choices, B, C, and D, are incorrect because the thoracoaromial artery primarily supplies the upper limb, the superior epigastric artery supplies the anterior abdominal wall, and the common carotid artery supplies the head and neck, but not the breast tissue. Therefore, based on the anatomical knowledge of arterial supply, the internal thoracic artery is the correct choice for the arterial supply of the breast.

What is the first stage of labour?

  • A. Dilation of the cervix.
  • B. Delivery of the infant.
  • C. Contraction of the uterus.
  • D. Delivery of the placent
Correct Answer: A

Rationale: The correct answer is A: Dilation of the cervix. This is the first stage of labor, where the cervix begins to open and thin out to allow the baby to pass through the birth canal. This process is crucial in preparing the body for delivery. The other choices are incorrect as they occur in later stages of labor. B: Delivery of the infant is the second stage, C: Contraction of the uterus is a general process throughout labor, and D: Delivery of the placenta is the third stage after the baby is born.

There are ____________ facial bones

  • A. 14
  • B. 22
  • C. 50
  • D. 16
Correct Answer: B

Rationale: The correct answer is B: 22. There are a total of 22 facial bones in the human skull. These bones include the mandible, maxilla, zygomatic bone, nasal bone, and others. Understanding human anatomy is crucial for healthcare professionals. Choice A (14) is too low and does not accurately represent the number of facial bones. Choice C (50) is too high and exceeds the actual count of facial bones. Choice D (16) is also incorrect as it falls short of the correct count of 22. Knowing the exact number of facial bones is important for various medical fields such as surgery, dentistry, and radiology.

The nurse recognizes which patient has the highest risk of endometrial cancer?

  • A. A 24-year-old woman with menarche at age 9
  • B. A 30-year-old woman who started menstruating at age 19
  • C. A 42-year-old woman who reached menopause at age 40
  • D. A 64-year-old woman who had irregular, heavy menstrual cycles
Correct Answer: A

Rationale: The correct answer is A because early menarche (age 9) and late menopause increase the lifetime exposure of estrogen, a known risk factor for endometrial cancer. Choice B has a later menarche age, reducing estrogen exposure. Choice C's early menopause decreases estrogen exposure. Choice D's irregular cycles may indicate hormonal imbalances but don't directly relate to increased estrogen exposure.
