Uterine tubes are otherwise called as
- A. Vas deferens
- B. Epididymis
- C. Fallopian tubes
- D. Vagina
Correct Answer: C
Rationale: The correct answer is C: Fallopian tubes. These tubes are also known as uterine tubes because they connect the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus. The other choices are incorrect because:
A: Vas deferens is a tube that carries sperm from the epididymis to the urethra in males.
B: Epididymis is a coiled tube located on the back of each testicle where sperm mature.
D: Vagina is the muscular tube that connects the cervix to the external genitalia in females.

How many chromosomes are present in a sperm?
- A. 1
- B. 2
- C. 12
- D. 23
Correct Answer: D
Rationale: The correct answer is D: 23. Sperm cells are haploid, meaning they contain half the number of chromosomes as normal body cells. In humans, normal body cells have 46 chromosomes (23 pairs), while sperm cells have only 23 chromosomes. This is essential for maintaining the correct chromosome number after fertilization.
A: 1 - Incorrect. Sperm cells cannot have only 1 chromosome as they need to contribute genetic material during fertilization.
B: 2 - Incorrect. Having only 2 chromosomes would not provide sufficient genetic diversity for offspring.
C: 12 - Incorrect. This number does not align with the haploid nature of sperm cells in humans with 23 chromosomes.
The scrotum:
- A. is located above the external male genital organ;
- B. shelters the male gonad;
- C. is made up of concentric tunics, a continuation of the ones from the anterior abdominal wall;
- D. is part of the external genital organs;
Correct Answer: B
Rationale: The correct answer is B: shelters the male gonad. The scrotum houses and protects the testes, the male gonads responsible for sperm production. This is crucial for maintaining optimal temperature for spermatogenesis. Choices A, C, and D are incorrect as the scrotum is located below the external male genital organ, has separate tunics from the abdominal wall, and is considered part of the external genital organs.
During a history, a patient reports rectal bleeding, a warning sign of colorectal cancer. The nurse correlates which clinical finding with colorectal cancer?
- A. Thick, blood-tinged mucus within the rectum
- B. A pus-filled cavity in the anorectal area
- C. An irregular mass with raised edges on the rectal wall
- D. A small, smooth nodule protruding from the rectum
Correct Answer: C
Rationale: The correct answer is C because an irregular mass with raised edges on the rectal wall is a common clinical finding associated with colorectal cancer. This mass could be a tumor or polyp, which can lead to rectal bleeding. Option A is incorrect because thick, blood-tinged mucus is more commonly associated with inflammatory conditions. Option B is incorrect as a pus-filled cavity suggests an abscess or infection, not colorectal cancer. Option D is incorrect because a small, smooth nodule is more indicative of hemorrhoids rather than colorectal cancer.
