The glands that produce a thick, yellowish secretion which nourishes and activates sperm are the __
- A. bulbo-urethral glands
- B. prostate
- C. seminal glands (vesicles)
- D. ejaculatory duct
Correct Answer: A
Rationale: The correct answer is A: bulbo-urethral glands. These glands produce a thick, yellowish secretion known as pre-ejaculate or Cowper's fluid. It serves to nourish and activate sperm. The other choices are incorrect because:
B: The prostate gland produces a milky fluid that helps with sperm motility.
C: The seminal glands (vesicles) produce a fluid that provides energy for sperm.
D: The ejaculatory duct is a passageway for semen to leave the body, it does not produce any secretions.

Bones that form the roof and the upper part of the sides of the cranium
- A. Frontal bone
- B. Temporal bone
- C. Parietal bone
- D. Occipital bone
Correct Answer: C
Rationale: The correct answer is C: Parietal bone. The parietal bone forms the roof and upper part of the sides of the cranium. It articulates with other bones, such as the frontal, temporal, and occipital bones, to create the structure of the skull. The frontal bone (A) forms the forehead, the temporal bone (B) is located on the sides of the skull, and the occipital bone (D) forms the back and base of the skull. Therefore, the parietal bone is the only bone among the choices that specifically fits the description of forming the roof and upper part of the sides of the cranium.
The nurse monitors a client who has gone through an endoscopic examination. Following a culdoscopy, what does a nurse need to observe for in this client?
- A. The nurse observes the client for any discomfort in the shoulders.
- B. The nurse observes the client for the signs of internal bleeding and the symptoms of shock.
- C. The nurse observes the client for changes in skin color and for any rise in body temperature.
- D. The nurse observes the quantity and frequency of urinary output.
Correct Answer: A
Rationale: Discomfort in the shoulders is a common side effect after culdoscopy due to gas insufflation.
Regarding gross anatomy of the female reproductive system
- A. Ovarian vessels located in ovarian ligament
- B. Anteverted- anteflexed is the normal position of the uterus
- C. Pouch of douglas separated uterus from rectum
- D. Pulsation of uterine artery can be palpated at the posterior fornix of vagina
Correct Answer: D
Rationale: The correct answer is D because the pulsation of the uterine artery can indeed be palpated at the posterior fornix of the vagina. This is an important anatomical landmark used in gynecological examinations.
A: The ovarian vessels are located in the suspensory ligament of the ovary, not the ovarian ligament.
B: The normal position of the uterus is anteverted and anteflexed.
C: The Pouch of Douglas is a potential space between the uterus and rectum, not a structure that physically separates them.
The external male reproductive organs consist of the penis, testes, and
- A. urethra
- B. prostate
- C. scrotum
- D. seminal vesicle
Correct Answer: C
Rationale: The correct answer is C: scrotum. The scrotum is a pouch of skin that houses the testes, which are responsible for producing sperm and testosterone. It is considered an external male reproductive organ because it plays a crucial role in maintaining the optimal temperature for sperm production. The penis is also an external male reproductive organ, but it is not part of the scrotum. The urethra is a passage for both urine and semen, and while it is part of the male reproductive system, it is not considered an external reproductive organ. The prostate and seminal vesicle are internal male reproductive organs involved in producing and secreting seminal fluid, making them incorrect choices in this context.
The sperm cells:
- A. become mobile in the seminal fluid;
- B. are microscopic cells;
- C. are stored in the crotum;
- D. are of three different kinds;
Correct Answer: A
Rationale: Step-by-step rationale for choice A being correct:
1. Sperm cells need to be mobile to reach the egg for fertilization.
2. Seminal fluid provides the environment for sperm motility.
3. Sperm cells acquire motility in the seminal fluid due to specific nutrients and ions present.
Summary of why other choices are incorrect:
- Choice B: Being microscopic is a general characteristic of sperm cells but not specific to their mobility.
- Choice C: Sperm cells are stored in the epididymis, not the "crotum."
- Choice D: Sperm cells are all of the same kind, not three different kinds.
