The accessory glands of the male reproductive system are:
- A. corpus spongiosum;
- B. corpus cavernosum;
- C. penis;
- D. seminal vesicles;
Correct Answer: D
Rationale: The correct answer is D: seminal vesicles. Seminal vesicles are accessory glands that produce a significant portion of the fluid that makes up semen. They contribute nutrients and substances that support sperm viability and motility. Choices A, B, and C are incorrect as they are structures of the penis involved in erection and urination, not accessory glands of the male reproductive system.

The failure of a testes to descend is referred to as _____.
- A. inguinal hernia
- B. strangulated hernia
- C. vaginal process
- D. cryptorchidism
Correct Answer: D
Rationale: The correct answer is D: cryptorchidism. This is because cryptorchidism specifically refers to the failure of one or both testes to descend into the scrotum. It is a common condition in newborns and can lead to complications if not treated.
A: Inguinal hernia is the protrusion of abdominal contents through the inguinal canal, not related to testes descent.
B: Strangulated hernia occurs when the blood supply to the herniated tissue is cut off, not related to testes descent.
C: Vaginal process is a structure involved in testicular descent but does not describe the failure of testes descent itself.
Summary:
Cryptorchidism is the correct term for undescended testes, while the other options are unrelated conditions.
The entire process of spermatogenesis takes approximately ________.
- A. 25-50 days
- B. 64-72 days
- C. 120 days
- D. 1 year
Correct Answer: C
Rationale: The correct answer is C: 120 days. Spermatogenesis is the process of sperm production, which involves several stages including mitosis, meiosis, and maturation. It takes around 64 days for the sperm to develop from spermatogonia to mature spermatozoa in the seminiferous tubules. After that, the sperm undergo additional maturation in the epididymis for approximately 12-14 days. Therefore, the entire process of spermatogenesis, from the initial division of spermatogonia to the release of mature sperm, takes approximately 120 days.
Choice A (25-50 days) is too short for the complete process of spermatogenesis. Choice B (64-72 days) only covers the time for sperm development in the seminiferous tubules but does not include the maturation period in the epididymis. Choice D (1 year) is too long for spermatogenesis and does not accurately represent the
Three days after having a pelvic exenteration procedure, a client suddenly complains of a 'giving' sensation along her abdominal incision. You check under the dressing and find that the wound edges are open and loops of intestine are protruding. Which action should you take first?
- A. Call the client's surgeon and report that wound evisceration has occurred.
- B. Cover the wound with saline-soaked dressings.
- C. Don sterile gloves and gently replace the intestine back in the wound.
- D. Check the client's blood pressure and heart rate.
Correct Answer: B
Rationale: Covering the exposed tissue with saline-soaked dressings prevents drying and reduces risk of further complications.
To avoid a perineal tear the obstetrician cuts the perineum posteriorly before delivery. This process is called
- A. Perineorrhaphy
- B. Episiotomy
- C. Cesarean section
- D. Tubal ligation
Correct Answer: B
Rationale: The correct answer is B: Episiotomy. An episiotomy is a surgical incision made in the perineum during childbirth to enlarge the vaginal opening and prevent severe perineal tears. This procedure is performed to facilitate the delivery of the baby and reduce the risk of complications for both the mother and the baby. Perineorrhaphy (A) is a surgical repair of a perineal tear or episiotomy after childbirth, not the procedure of making the incision. Cesarean section (C) is a surgical procedure to deliver a baby through an incision in the mother's abdomen and uterus, not related to perineal tears. Tubal ligation (D) is a permanent form of female sterilization by blocking or sealing the fallopian tubes to prevent pregnancy, not relevant to perineal tears during childbirth.
The process of capacitation usually occurs in the _____.
- A. vagina
- B. testis
- C. prostate
- D. epididymis
Correct Answer: A
Rationale: The process of capacitation occurs in the female reproductive tract, specifically in the vagina. Capacitation is essential for sperm to fertilize an egg, where they undergo changes in the female reproductive tract to become more motile and capable of penetrating the egg. The vagina provides the ideal environment for capacitation to take place due to its specific pH, temperature, and components present in the cervical mucus. The other choices (B: testis, C: prostate, D: epididymis) are incorrect as capacitation is a process that occurs in the female reproductive tract, not in the male reproductive organs.
