Which structure lies posterior to the bladder and anterior to the rectum and secretes an alkaline, fructose filled fluid?
- A. Prostate
- B. bulbourethral gland
- C. Seminal vesicles
- D. Spongy urethra
Correct Answer: C
Rationale: The correct answer is C: Seminal vesicles. These glands are located posterior to the bladder and anterior to the rectum. They secrete an alkaline fluid rich in fructose, which nourishes and supports sperm viability. The other choices are incorrect because: A) The prostate is located below the bladder and surrounds the urethra, secreting a milky fluid; B) The bulbourethral gland is located below the prostate and secretes a clear, viscous fluid; D) The spongy urethra is a part of the male urethra that runs through the penis, responsible for transporting urine and semen.
What is the first structure to receive the oocyte?
- A. fimbriae
- B. uterine tube
- C. infundibulum
- D. uterus
Correct Answer: A
Rationale: The correct answer is A: fimbriae. Fimbriae are finger-like projections at the end of the fallopian tube that capture the released oocyte from the ovary during ovulation. The fimbriae create a gentle sweeping motion to guide the oocyte into the uterine tube for fertilization. The other choices are incorrect because the oocyte needs to be captured by the fimbriae before entering the uterine tube, infundibulum, or uterus. The fimbriae are the initial structure responsible for receiving the oocyte, making choice A the correct answer.
The testicular lobules:
- A. are delineated by connective septa separated from the tunica albuginea;
- B. are separated by interstitial tissue;
- C. are made up of 2-3 convoluted seminiferous tubules;
- D. spermatogenesis occurs at their levels;
Correct Answer: C
Rationale: The correct answer is C because testicular lobules are indeed made up of 2-3 convoluted seminiferous tubules where spermatogenesis occurs. This process of sperm production takes place within the seminiferous tubules, making option C the most accurate description of the testicular lobules.
A is incorrect because the testicular lobules are not delineated by connective septa separated from the tunica albuginea. B is also incorrect as interstitial tissue is found between the lobules, not separating each individual lobule. D is incorrect as spermatogenesis specifically occurs within the seminiferous tubules, not at the level of the testicular lobules.

A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses’ best response?
- A. “Do you want to talk about the need for that much exercise?”
- B. “Exercise is healthy but can decrease body fat and cause irregular periods.”
- C. “Bingeing and purging can cause electrolyte problems in your body.”
- D. “Anorexic behavior can result in decreased estrogen levels.”
Correct Answer: B
Rationale: Rationale:
The correct answer is B because excessive exercise can lead to decreased body fat, which in turn disrupts hormone levels causing irregular periods. Choice A is inappropriate as it doesn't address the underlying issue. Choices C and D are incorrect as they refer to different conditions (bulimia and anorexia) not related to the client's concern.
