Prophase I of the spermatocyte phase lasts approximately:
- A. 2 hours
- B. 24 hours
- C. 2 days
- D. 16 days
Correct Answer: D
Rationale: The correct answer is D (16 days) because prophase I of spermatocyte phase involves complex processes like chromosome pairing and recombination, which take time. It is a crucial stage in sperm formation. Choices A, B, and C are incorrect as they underestimate the duration required for these intricate cellular events to occur. A shorter timeframe would not allow for proper genetic exchange and segregation, essential for genetic diversity in offspring. Thus, a longer duration like 16 days is necessary for the completion of prophase I in spermatocyte phase.

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.
The average menstrual cycle is
- A. 14 days
- B. 18 days
- C. 24 days
- D. 28 days
Correct Answer: D
Rationale: The correct answer is D (28 days) as it is the average length of a menstrual cycle, which is typically counted from the first day of one period to the first day of the next. The menstrual cycle is controlled by hormonal changes and the average duration is around 28 days. This length allows for the proper preparation and shedding of the uterine lining. Choices A, B, and C are incorrect as they do not align with the typical length of a menstrual cycle, which is around 28 days.
A patient complains of dysuria, yellow-green vaginal discharge, and vulvar itching. The nurse suspects which sexually transmitted disease?
- A. Syphilis
- B. Gonorrhea
- C. Genital warts
- D. Chlamydia
Correct Answer: B
Rationale: The correct answer is B: Gonorrhea. Dysuria, yellow-green discharge, and vulvar itching are classic symptoms of gonorrhea. The causative agent, Neisseria gonorrhoeae, infects the genital tract. Syphilis (A) presents with painless sores, not discharge. Genital warts (C) are caused by human papillomavirus and present as warts, not discharge. Chlamydia (D) can cause similar symptoms, but the characteristic discharge in this case points more towards gonorrhea.
The egg is fertilized in which anatomical structure?
- A. Vagina
- B. Uterus
- C. uterine (fallopian) tube
- D. cervix
Correct Answer: B
Rationale: The correct answer is B: Uterus. After fertilization, the egg travels through the fallopian tube and implants in the uterus for further development. The vagina is the birth canal, not the site of fertilization. The fallopian tube is where fertilization typically occurs, but the actual implantation of the fertilized egg occurs in the uterus. The cervix is the lower part of the uterus that connects to the vagina and plays a role in pregnancy but is not where fertilization occurs.
The hormone(s) responsible for hymen. secondary sex characteristics in
- A. The vagina is the female females is/are ________.
- B. estrogens
- C. The innermost lining of the
- D. progesterone
Correct Answer: B
Rationale: The correct answer is B: estrogens. Estrogens are the primary hormones responsible for the development of secondary sex characteristics in females, including the formation of the hymen. Estrogens play a crucial role in regulating menstrual cycles, breast development, and overall reproductive health in females. Progesterone (choice D) is primarily involved in regulating the menstrual cycle and supporting pregnancy but is not directly responsible for hymen development. Choices A and C do not provide accurate or relevant information related to the development of secondary sex characteristics or the hymen.
