Fertilization occurs in the:
- A. uterus
- B. fallopian tubes
- C. labia
- D. vagina
Correct Answer: B
Rationale: The correct answer is B: fallopian tubes. Fertilization occurs in the fallopian tubes where the sperm meets the egg. The fallopian tubes are where the egg is released from the ovary and where fertilization takes place. The uterus (choice A) is where the fertilized egg implants and develops into a fetus. The labia (choice C) are external genital structures and do not play a role in fertilization. The vagina (choice D) is the birth canal and does not directly participate in fertilization. Therefore, the fallopian tubes are the correct choice for the site of fertilization in the female reproductive system.

Spermatogonia
- A. are germ cell.
- B. are diploid cell.
- C. are male gametes.
- D. have flagell
Correct Answer: A
Rationale: The correct answer is A because spermatogonia are indeed germ cells that give rise to sperm cells through the process of spermatogenesis. They are diploid cells, not male gametes. Spermatogonia do not have flagella; instead, mature sperm cells have flagella for motility. So, the correct answer is A because spermatogonia are the precursor cells for sperm cells, they are diploid, and they do not have flagella.
Contraindications to IUD
- A. Young age
- B. Nulliparity
- C. Ectopic pregnancy
- D. Abnormal uterine bleeding
Correct Answer: C
Rationale: Correct Answer: C - Ectopic pregnancy
Rationale:
1. IUDs do not prevent ectopic pregnancies.
2. IUD insertion increases the risk of ectopic pregnancy.
3. Ectopic pregnancy is a serious complication of IUD use.
Summary of other choices:
A: Young age - Age alone is not a contraindication.
B: Nulliparity - Being nulliparous is not a contraindication.
D: Abnormal uterine bleeding - It is a relative, not absolute contraindication.
Which of the following is a reason for providing early discharge instructions and making arrangements for home care for clients undergoing mastectomy?

- D. The suicidal tendencies in women undergoing a mastectomy are high.
Correct Answer: C
Rationale: Short hospital stays are common, necessitating early discharge planning.
The female sex of the child involves the following during fecundation:
- A. the spermatozoon should contain the X sex chromosome;
- B. the spermatozoon should contain the Y sex chromosome;
- C. the ovule should contain the contain the Y sex chromosome;
- D. the spermatozoon should contain the X sex chromosome and the ovule should contain the contain the X sex chromosome
Correct Answer: D
Rationale: The correct answer is D because during fecundation, the female sex of the child is determined by the presence of the X sex chromosome in the spermatozoon and the ovule. This leads to the combination of XX chromosomes, resulting in a female child. Choice A (spermatozoon with X chromosome) alone would lead to a female child, but it requires the ovule to also have an X chromosome for the correct combination. Choice B (spermatozoon with Y chromosome) would result in a male child. Choice C (ovule with Y chromosome) is incorrect as the ovule always contains an X chromosome. Thus, the correct combination for a female child is when the spermatozoon contains the X chromosome and the ovule contains the X chromosome.
The 16 feet long tube that is coiled and located above the
- A. epididymis
- B. Vas deferens
- C. Urethra
- D. Ureter
Correct Answer: A
Rationale: The correct answer is A: epididymis. The epididymis is a coiled tube located on the back of each testicle, approximately 16 feet long when unraveled. It plays a crucial role in sperm maturation and storage. The other choices, B: Vas deferens, C: Urethra, and D: Ureter, are incorrect as they are not coiled tubes located above the testicles and do not have the same function as the epididymis in sperm development and storage.
