Sterilization in the male is accomplished by excising a small portion of the:
- A. Vas deferens
- B. Ejaculatory duct
- C. Epididymis
- D. Seminal vesicles
Correct Answer: A
Rationale: The correct answer is A: Vas deferens. Sterilization in males is typically done through a procedure called a vasectomy, where a small portion of the vas deferens is excised to prevent the transportation of sperm from the testicles to the urethra. The vas deferens is the duct that carries sperm from the epididymis to the ejaculatory duct. Excising a portion of the ejaculatory duct, epididymis, or seminal vesicles would not prevent the transportation of sperm, making choices B, C, and D incorrect.

Wolffian duct is also known as ____________.
- A. Mesonephric duct
- B. Ejaculatory duct
- C. Major sublingual duct
- D. Cystic duct
Correct Answer: A
Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is also known as the mesonephric duct because it develops in the embryo to form the male reproductive system. It gives rise to various structures such as the epididymis, vas deferens, and seminal vesicles. The other choices are incorrect because the ejaculatory duct is formed by the union of the vas deferens and seminal vesicle, the major sublingual duct is associated with saliva production, and the cystic duct is part of the biliary system and not related to the male reproductive system.
Which statements about the ovarian follicles are true:
- A. they are located in the cortical area of the ovary;
- B. they are present in the ovary since birth;
- C. they are formed in the ovary at puberty;
- D. they are found in successive stages of evolution;
Correct Answer: B
Rationale: The correct answer is B because ovarian follicles are actually present in the ovary since birth. They are formed during fetal development and remain in a dormant state until puberty. Choice A is incorrect because follicles are located in the medullary area of the ovary, not the cortical area. Choice C is incorrect because follicles are formed before puberty. Choice D is incorrect because follicles do not go through stages of evolution but rather stages of development.
The uterine phase where the thickness of the endometrium doubles is the
- A. Menstrual phase
- B. Preovulatory phase
- C. Proliferative phase
- D. Follicular phase
Correct Answer: C
Rationale: The correct answer is C: Proliferative phase. During this phase, estrogen levels increase, stimulating the endometrium to thicken and proliferate. This prepares the uterus for potential implantation of a fertilized egg. The other choices are incorrect because: A: Menstrual phase is when the endometrium sheds, not thickens. B: Preovulatory phase is characterized by the maturation of the ovarian follicles, not endometrial thickening. D: Follicular phase is synonymous with the preovulatory phase and focuses on ovarian follicle development, not endometrial thickening.
The tailbone is also called as
- A. Lumbar vertebra
- B. Sacrum
- C. Coccyx
- D. Cauda equina
Correct Answer: C
Rationale: The correct answer is C: Coccyx. The tailbone is also known as the coccyx, which is a small triangular bone at the base of the spine. It consists of 3-5 fused vertebrae. The lumbar vertebra (A) is part of the lower back, the sacrum (B) is a large triangular bone at the base of the spine, and the cauda equina (D) is a bundle of nerves at the lower end of the spinal cord. The coccyx specifically refers to the tailbone, making it the correct choice in this context.
The mother of an 18-year-old girl asks the nurse which screening her daughter should receive now based on evidence-based recommendations. Which suggestion by the nurse is best?
- A. Papanicolaou test
- B. Human papilloma virus (HPV) test
- C. Mammogram
- D. No screenings at this time
Correct Answer: D
Rationale: The correct answer is D because evidence-based recommendations do not support routine screening for cervical cancer (Papanicolaou test) or breast cancer (mammogram) in asymptomatic individuals under 21. HPV test is not recommended as a standalone screening for young women. No screenings at this time aligns with current guidelines to avoid unnecessary testing and potential harm in low-risk populations. It's important to focus on preventive measures such as vaccinations and healthy lifestyle choices rather than invasive screenings for this age group.
