The scrotum:
- A. is located above the external male genital organ;
- B. shelters the male gonad;
- C. is made up of concentric tunics, a continuation of the ones from the anterior abdominal wall;
- D. is part of the external genital organs;
Correct Answer: B
Rationale: The correct answer is B: shelters the male gonad. The scrotum houses and protects the testes, the male gonads responsible for sperm production. This is crucial for maintaining optimal temperature for spermatogenesis. Choices A, C, and D are incorrect as the scrotum is located below the external male genital organ, has separate tunics from the abdominal wall, and is considered part of the external genital organs.

Abdominal pain caused by uterine cramps during a menstrual period is known as _________.
- A. dysmenorrhoea
- B. hypermenorrhoea
- C. menometrorrhagia
- D. polymenorrhoea
Correct Answer: A
Rationale: The correct answer is A: dysmenorrhoea. Dysmenorrhoea specifically refers to abdominal pain caused by uterine cramps during menstruation. "Dys-" means difficult or painful, and "menorrhoea" refers to menstruation.
Choice B, hypermenorrhoea, refers to abnormally heavy menstrual bleeding, not abdominal pain. Choice C, menometrorrhagia, refers to irregular and excessive uterine bleeding, not specifically related to abdominal pain. Choice D, polymenorrhoea, refers to frequent menstrual cycles, not abdominal pain.
In summary, dysmenorrhoea is the correct answer because it accurately describes the abdominal pain associated with uterine cramps during menstruation, while the other choices pertain to different menstrual abnormalities.
A 67-year-old client with incomplete bladder emptying caused by BPH has a new prescription for tamsulosin (Flomax). Which statement about tamsulosin is most important to include when teaching this client?
- A. This medication will improve your symptoms by shrinking the prostate.
- B. The force of your urinary stream will probably increase.
- C. Your blood pressure will decrease as a result of taking this medication.
- D. You should avoid making sudden changes in position.
Correct Answer: D
Rationale: Tamsulosin can cause orthostatic hypotension, so advising the client to avoid sudden position changes is crucial.
How many chromosomes are present in a sperm?
- A. 1
- B. 2
- C. 12
- D. 23
Correct Answer: D
Rationale: The correct answer is D: 23. Sperm cells are haploid, meaning they contain half the number of chromosomes as normal body cells. In humans, normal body cells have 46 chromosomes (23 pairs), while sperm cells have only 23 chromosomes. This is essential for maintaining the correct chromosome number after fertilization.
A: 1 - Incorrect. Sperm cells cannot have only 1 chromosome as they need to contribute genetic material during fertilization.
B: 2 - Incorrect. Having only 2 chromosomes would not provide sufficient genetic diversity for offspring.
C: 12 - Incorrect. This number does not align with the haploid nature of sperm cells in humans with 23 chromosomes.
Which of the following is not a contribution of the reproductive system to the body systems?
- A. Stimulation of growth and maintenance of bones of the skeletal system
- B. Lowering blood cholesterol level in males under the age of 50
- C. Increasing the rate and depth of breathing during sexual arousal
- D. Stimulating the growth of skeletal muscles in males
Correct Answer: C
Rationale: The correct answer is C: Increasing the rate and depth of breathing during sexual arousal. The reproductive system does not directly contribute to the rate and depth of breathing. The main function of the reproductive system is to produce and deliver gametes for reproduction. It does not have a direct role in regulating respiratory functions. Choices A, B, and D are incorrect because the reproductive system does contribute to maintaining bone health, regulating cholesterol levels in males, and stimulating muscle growth in males. These functions are known contributions of the reproductive system to the body systems.
Of the two functional areas of the years of age is known as ________. It blastocyst, the three primary germ is during this time that the reproductive layers form from the ________. organs grow to their adult size and
- A. amnion become functional under the influence
- B. morula of hormones.
- C. inner cell mass
- D. adulthood
Correct Answer: D
Rationale: The correct answer is D: adulthood. The question is referring to the two functional areas of life - childhood and adulthood. During adulthood, organs grow to their adult size and mature, reproductive organs become functional under the influence of hormones.
A: amnion become functional under the influence - Incorrect. Amnion is a membrane surrounding the embryo, not related to the functional areas of age.
B: morula of hormones - Incorrect. Morula is an early stage of embryonic development, not related to the functional areas of age.
C: inner cell mass - Incorrect. Inner cell mass is a part of the blastocyst, not related to the functional areas of age.
