The uterus is a ...... organ:
- A. funnel-shaped;
- B. unpaired;
- C. cavitary;
- D. muscular
Correct Answer: D
Rationale: The correct answer is D: muscular. The uterus is composed of smooth muscle tissue, allowing it to contract during childbirth and menstruation. This contraction is essential for the expulsion of the fetus or uterine lining. Funnel-shaped (A) and cavitary (C) describe the shape and structure of the uterus, but they do not define its primary function. Unpaired (B) is incorrect as the uterus is a paired organ in the female reproductive system.

Fecundation:
- A. is monospermic;
- B. consists in the fusion between the male and female gametes;
- C. consists in the grafting of the egg at the level of the Fallopian tube;
- D. requires the existence of several fecundated spermatozoa;
Correct Answer: B
Rationale: The correct answer is B: consists in the fusion between the male and female gametes. Fecundation, also known as fertilization, is the process where a sperm cell fuses with an egg cell to form a zygote. This is a crucial step in sexual reproduction. The male gamete (sperm) and the female gamete (egg) come together to combine their genetic material, resulting in the formation of a new individual. The other choices are incorrect because: A) Monospermic means involving only one sperm, which is not accurate as multiple sperm may reach the egg but only one will fertilize it. C) Grafting of the egg at the Fallopian tube is not how fertilization occurs; fertilization typically takes place in the fallopian tube but does not involve grafting. D) Fecundation does not require the existence of several fecundated spermatozoa; only one sperm is needed for fertilization to occur.
A patient asks when she can stop having Pap (Papanicolaou) tests. What is the nurse’s most appropriate response?
- A. Until you are no longer sexually active.
- B. Through age 65.
- C. Until you begin menopause.
- D. Through the end of menopause.
Correct Answer: B
Rationale: The correct answer is B: Through age 65. This is because current guidelines recommend that women continue to have Pap tests every 3-5 years until age 65, assuming previous tests have been normal. This age cutoff is based on the decreasing risk of cervical cancer with age and the low likelihood of developing new HPV infections after this age. Choices A, C, and D are incorrect because they do not align with the most up-to-date screening recommendations and may lead to unnecessary testing or missed opportunities for appropriate screening.
Which of these is not a function of estrogen?
- A. decreases adipose
- B. breast development
- C. increased skin blood vessels
- D. enlarges clitoris
Correct Answer: A
Rationale: Estrogen does not decrease adipose tissue; it actually promotes fat deposition in certain body areas. Breast development, increased skin blood vessels, and enlargement of the clitoris are all functions of estrogen. Adipose tissue regulation is influenced by other hormones like insulin and cortisol.
The general meaning of the term "corpus" is best described by which of the following?
- A. Abdomen
- B. Body
- C. Death
- D. Head
Correct Answer: B
Rationale: The correct answer is B: Body. Corpus commonly refers to a collection of written or spoken texts, which together form a body of work. "Body" is the best choice as it encompasses the idea of a collection or group of related items. A is incorrect as it refers specifically to the abdomen, not the general term. C, Death, and D, Head, are unrelated to the general meaning of "corpus" as they do not convey the idea of a body or collection.
A surge of FSH and LH is induced in the adenohypophysis 24 hours before ovulation and the first meiotic division of the primary oocyte resumes. At what stage does the oocyte become arrested until it becomes fertilized?
- A. First meiotic division, prophase
- B. First meiotic division, metaphase
- C. Second meiotic division, prophase
- D. Second meiotic division, metaphase
Correct Answer: D
Rationale: The correct answer is D: Second meiotic division, metaphase. After the surge of FSH and LH induces the first meiotic division to resume, the oocyte becomes arrested at the metaphase stage of the second meiotic division until fertilization. This arrest allows for the completion of meiosis upon fertilization. Choices A and B are incorrect because the oocyte does not become arrested at the prophase or metaphase of the first meiotic division. Choice C is incorrect because the oocyte does not become arrested at the prophase of the second meiotic division, but rather at the metaphase stage.
