The epididymal duct:
- A. is an intratesticular spermatic duct;
- B. continues with the deferent duct;
- C. continues with the testicular efferent ducts (vas efferens);
- D. part of the extratesticular spermatic ducts.
Correct Answer: B
Rationale: Step 1: The epididymal duct is a coiled tube located on the posterior surface of the testis.
Step 2: It continues as the deferent duct (vas deferens) which is responsible for transporting sperm from the epididymis to the ejaculatory duct.
Step 3: Therefore, choice B is correct as the epididymal duct indeed continues as the deferent duct.
Summary:
A: Incorrect - The epididymal duct is not located within the testis.
C: Incorrect - The testicular efferent ducts are separate from the epididymal duct.
D: Incorrect - The epididymal duct is considered part of the male reproductive system within the scrotum, not outside it.

The function of the epididymis is
- A. Sperm maturation
- B. Produce sperm
- C. Spermatid storage
- D. Provide nutrition to sperm
Correct Answer: A
Rationale: The correct answer is A: Sperm maturation. The epididymis is a coiled tube where sperm undergo maturation, gaining motility and ability to fertilize an egg. It does not produce sperm (incorrect B), but stores sperm for a short period (incorrect C) before ejaculation. It also does not provide nutrition to sperm (incorrect D).
A zygote is
- A. the same as an ovum
- B. another name for secondary oocyte
- C. a diploid fertilized ovum
- D. the same as polar body
Correct Answer: C
Rationale: The correct answer is C: a diploid fertilized ovum. A zygote is formed when a sperm fertilizes an ovum, resulting in a diploid cell with a complete set of chromosomes. This marks the beginning of a new individual.
A) Incorrect: An ovum is a haploid cell produced by the female reproductive system.
B) Incorrect: A secondary oocyte is a haploid cell that has undergone meiosis II but has not been fertilized yet.
D) Incorrect: A polar body is a haploid cell that is produced during oogenesis and eventually disintegrates.
When men age, what is the effect of prostate gland enlargement?
- A. It compromises the ability to fertilize ova
- B. It compromises erectile function
- C. It compromises urination
- D. It compromises sperm production
Correct Answer: C
Rationale: Prostate gland enlargement commonly affects urination by obstructing the urethra.
The human reproductive system is regulated by
- A. restriction enzymes
- B. antigens
- C. complex carbohydrates
- D. hormones
Correct Answer: D
Rationale: The correct answer is D: hormones. The human reproductive system is regulated by hormones such as estrogen, progesterone, testosterone, and others. Hormones play a crucial role in controlling the menstrual cycle, sperm production, ovulation, and other reproductive processes. They help in maintaining the proper functioning of the reproductive organs and influencing sexual characteristics.
A: restriction enzymes are involved in DNA manipulation and have no direct role in regulating the human reproductive system.
B: antigens are substances that trigger an immune response, not involved in regulating the reproductive system.
C: complex carbohydrates are a source of energy and not directly involved in regulating the human reproductive system.
In summary, hormones are the primary regulators of the human reproductive system, influencing various processes essential for reproduction.
A patient asks when she should make an appointment for her first Pap (Papanicolaou) test to screen for cervical cancer. What is the nurse’s most appropriate response?
- A. There is no need for Pap tests until after you have become pregnant.
- B. All women should have the first Pap test after reaching menarche.
- C. All women should have the first Pap test after they are 19 years of age.
- D. All women should have the first Pap test when they become sexually active or at age 21.
Correct Answer: D
Rationale: The correct answer is D. The first Pap test should be done when a woman becomes sexually active or at age 21, whichever comes first. This is because cervical cancer is associated with the human papillomavirus (HPV), which is a sexually transmitted infection. Screening at this stage helps detect any abnormalities early on, increasing the chances of successful treatment.
A: Incorrect. Waiting until after pregnancy is not recommended as early detection is crucial in preventing cervical cancer.
B: Incorrect. The age of menarche is not a reliable indicator for when to start screening for cervical cancer.
C: Incorrect. Waiting until 19 may miss early signs of cervical abnormalities that could lead to cancer.
In summary, choice D is the most appropriate response as it aligns with current screening guidelines and focuses on early detection for optimal outcomes.
