The Fallopian tubes:
- A. are pair muscular-membranous ducts;
- B. are part of the female genital ducts;
- C. are located between ovary and uterus;
- D. capture the ovule released by the ovary;
Correct Answer: C
Rationale: The correct answer is C because the Fallopian tubes are indeed located between the ovary and the uterus. This is essential for the transportation of the released ovum from the ovary to the uterus for possible fertilization. Choice A is incorrect as the Fallopian tubes are not solely muscular-membranous ducts; they have ciliated epithelial cells aiding in the movement of the ovum. Choice B is too broad, as the Fallopian tubes are just one part of the female reproductive system. Choice D is incorrect because the Fallopian tubes do not capture the ovule; rather, they provide a pathway for its transport.

The pregnancy period is:
- A. 120 days;
- B. nine weeks;
- C. 280 weeks;
- D. 280 days;
Correct Answer: D
Rationale: The correct answer is D: 280 days. The pregnancy period, also known as gestation, typically lasts around 280 days from the first day of the last menstrual period to the birth of the baby. This duration is calculated based on the average length of a full-term pregnancy, which is approximately 40 weeks. It is important to note that individual pregnancies may vary slightly in duration, but the standard reference is 280 days.
Explanation of other choices:
A: 120 days - This is too short for a full-term pregnancy.
B: Nine weeks - This is only around 63 days, which is far less than the average gestation period.
C: 280 weeks - This is equivalent to around 1960 days, which is much longer than a typical pregnancy duration.
The male reproductive system is made up of the following structures, EXCEPT:
- A. prostate;
- B. testicle;
- C. spermatic ducts;
- D. vestibular bulbs;
Correct Answer: D
Rationale: The correct answer is D: vestibular bulbs. The male reproductive system consists of the prostate, testicles, and spermatic ducts, all essential for the production, storage, and transportation of sperm. Vestibular bulbs are actually part of the female reproductive system, involved in sexual arousal, and not found in the male reproductive system. Therefore, it is the only structure listed that is not a part of the male reproductive system.
Each menstrual cycle is considered as a period of ________
- A. 28 days
- B. 30 days
- C. 42 days
- D. 14 days
Correct Answer: A
Rationale: The correct answer is A: 28 days because the average menstrual cycle length is typically around 28 days, although it can vary. The menstrual cycle consists of different phases such as menstruation, follicular phase, ovulation, and luteal phase, which collectively last around 28 days on average. Choice B (30 days), C (42 days), and D (14 days) are incorrect because they do not represent the typical duration of a menstrual cycle. It's important to note that individual variations in cycle length are common, but 28 days is considered a standard reference point.
Which structure is the site of sperm production?
- A. Vas deferens
- B. Seminiferous tubules
- C. Albuginea
- D. Epididymis
Correct Answer: B
Rationale: The correct answer is B: Seminiferous tubules. These tubules are located within the testes and are the specific structures where sperm production occurs through a process called spermatogenesis. Sperm cells are produced within the seminiferous tubules and then mature as they move through the epididymis (choice D) and vas deferens (choice A). The albuginea (choice C) is the tough outer covering of the testes and does not play a direct role in sperm production. Therefore, the seminiferous tubules are the primary site for sperm production in the male reproductive system.
The nurse will plan to teach a 51-yr-old man who is scheduled for an annual physical examination about a(n)
- A. increased risk for testicular cancer.
- B. possible changes in erectile function.
- C. normal decreases in testosterone level.
- D. prostate specific antigen (PSA) testing.
Correct Answer: C
Rationale: The correct answer is C: normal decreases in testosterone level. At the age of 51, it is important to educate the man about the normal age-related decline in testosterone levels, which can affect various aspects of health. This information will help manage expectations and address potential symptoms. Option A is incorrect as testicular cancer risk typically decreases with age. Option B may be a concern but is not the primary focus of education for a routine physical exam. Option D (PSA testing) is more relevant for prostate health, which is not the main focus of education for a 51-year-old man's annual physical exam.
