The spermatozoon:
- A. is the primordial male cell;
- B. is a microscopic cell;
- C. forms within the interstitial cells;
- D. is a diploid cell;
Correct Answer: A
Rationale: The correct answer is A because the spermatozoon is indeed the primordial male cell, the precursor to all other male reproductive cells. Choice B is incorrect because the term "microscopic cell" is too broad and does not specifically define the spermatozoon. Choice C is incorrect because spermatozoa are actually formed within the seminiferous tubules of the testes, not the interstitial cells. Choice D is incorrect because spermatozoa are haploid cells, not diploid. Therefore, only choice A accurately describes the nature and origin of the spermatozoon.

Which structure is the site of sperm production?
- A. Vas deferens
- B. Seminiferous tubules
- C. Albuginea
- D. Epididymis
Correct Answer: B
Rationale: The correct answer is B: Seminiferous tubules. These tubules are located within the testes and are the specific structures where sperm production occurs through a process called spermatogenesis. Sperm cells are produced within the seminiferous tubules and then mature as they move through the epididymis (choice D) and vas deferens (choice A). The albuginea (choice C) is the tough outer covering of the testes and does not play a direct role in sperm production. Therefore, the seminiferous tubules are the primary site for sperm production in the male reproductive system.
The day after having a radical prostatectomy, your client has many blood clots in the urinary catheter and states he has frequent bladder spasms. You notice occasional urine leakage around the catheter at the urinary meatus. The client says that his right calf is sore and complains that he feels short of breath. Which action will you take first?
- A. Irrigate the catheter with 50 mL of sterile saline.
- B. Administer oxybutynin (Ditropan) 5 mg orally.
- C. Dorsiflex the foot to check for Homans' sign.
- D. Obtain an oxygen saturation using pulse oximetry.
Correct Answer: D
Rationale: Shortness of breath and calf soreness suggest a pulmonary embolism; obtaining oxygen saturation is critical.
