Nokea
Which term includes the other terms?
- A. spermatozoa
- B. alkaline mucus
- C. semen
- D. fructose
Correct Answer: C
Rationale: The correct answer is C: semen. Semen is the fluid that contains spermatozoa, alkaline mucus, and fructose. Spermatozoa are the male reproductive cells, alkaline mucus helps neutralize vaginal acidity, and fructose provides energy for sperm. Semen is the combination of these components, making it the term that encompasses all the other terms listed. A: spermatozoa is incorrect because it is just one component of semen. B: alkaline mucus is incorrect as it is a separate component in semen. D: fructose is incorrect because it is also just one component found in semen.

The best time for a woman of childbearing age to perform breast self-examination is
- A. during her menstrual period
- B. 2 days before the onset of her menstrual period

A “birth control” compound for men has been sought for several decades. Which of the following would provide effective sterility?
- A. Substance that mimics the actions of luteinizing hormone
- B. Substance that blocks the actions of inhibin
- C. Substance that blocks the actions of follicle-stimulating hormone
- D. Substance that mimics the actions of gonadotropin-releasing hormone
Correct Answer: C
Rationale: The correct answer is C: Substance that blocks the actions of follicle-stimulating hormone. By blocking the actions of FSH, sperm production in the testes would be inhibited, leading to effective sterility. FSH plays a crucial role in stimulating sperm production, so blocking its actions would prevent the development of mature sperm.
Explanation for why the other choices are incorrect:
A: Substance that mimics the actions of luteinizing hormone - Mimicking LH would not necessarily lead to effective sterility in men.
B: Substance that blocks the actions of inhibin - Inhibin regulates FSH secretion but blocking it would not directly lead to effective sterility.
D: Substance that mimics the actions of gonadotropin-releasing hormone - Mimicking GnRH would not directly impact sperm production and sterility.
The primary spermatocytes:
- A. are formed by spermatogonia mitosis;
- B. have a complete number of chromosomes;
- C. generate secondary spermatocytes;
- D. are diploid cells;
Correct Answer: D
Rationale: The correct answer is D because primary spermatocytes are diploid cells, containing a complete set of chromosomes (46 in humans). They are formed by spermatogonia through a process called meiosis. During meiosis, the primary spermatocytes undergo two divisions to generate haploid secondary spermatocytes with half the number of chromosomes. Choices A and C are incorrect because primary spermatocytes are formed by spermatogonia undergoing meiosis, not mitosis, and they generate secondary spermatocytes, not the other way around. Choice B is incorrect because primary spermatocytes are diploid, not haploid.
Which of the following nursing interventions are advised for clients with prostate cancer to avoid an infection related to the home-care of a Foley catheter?
- A. Boil the leg bag regularly in a solution of hot water and vinegar for 15 minutes during the cleaning.
- B. Disinfect several inches of the catheter with alcohol or any other antiseptic agent before the insertion.
- C. Clean the leg bag by using soap and water and then rinse it with a 1:7 solution of vinegar and water.
- D. Open the connections between the leg bag and the catheter only once in 15 days to reduce the risks of microbial entry.
Correct Answer: C
Rationale: Proper cleaning and maintenance of the catheter equipment are crucial to preventing infections.
Also called the birth canal, this is a muscular passageway from the cervix to the outside of the female's body:
- A. Vagina
- B. Uterus
- C. Fallopian tube
- D. obstetrician
Correct Answer: A
Rationale: The correct answer is A: Vagina. The vagina is the muscular passageway from the cervix to the outside of the female's body, serving as the birth canal. It is where sexual intercourse occurs and where menstrual flow exits the body. The uterus (B) is the organ where a fertilized egg implants and develops into a fetus, not the birth canal. Fallopian tubes (C) are where fertilization of an egg typically occurs, not part of the birth canal. Obstetrician (D) is a medical professional specializing in childbirth and pregnancy, not a part of the female reproductive anatomy.
