Which of the following terms indicate the beginning of the fertile period when gametes are produced and secondary sex characteristics appear?

  • A. Teenage
  • B. Adolescence
  • C. Puberty
  • D. Juvenile
Correct Answer: C

Rationale: The correct answer is C: Puberty. Puberty is the stage of development when gametes are produced and secondary sex characteristics appear, marking the beginning of the fertile period. This period typically occurs between the ages of 10 to 14 in females and 12 to 16 in males.

A: Teenage - Incorrect. Teenage refers to the age range between 13 to 19 and does not specifically indicate the onset of gamete production and secondary sex characteristics.

B: Adolescence - Incorrect. Adolescence is a broader term that encompasses the period from childhood to adulthood, including puberty, but it does not specifically indicate the beginning of the fertile period.

D: Juvenile - Incorrect. Juvenile refers to a young organism that has not reached sexual maturity and does not signify the beginning of gamete production and secondary sex characteristics.

For fertilization to be accomplished, of the secondary sex characteristics sperm release enzymes to break seen in young women? down the corona radiata from their

  • A. enlargement of the accessory ________.
  • B. mitochondria
  • C. breast development
  • D. acrosomes
Correct Answer: D

Rationale: The correct answer is D: acrosomes. Acrosomes are specialized vesicles in the head of the sperm that contain enzymes to help the sperm penetrate the outer layer of the egg during fertilization. Enlargement of the accessory organs (choice A), mitochondria (choice B), and breast development (choice C) are not directly related to the process of fertilization and do not involve the release of enzymes to break down the corona radiata. Acrosomes play a crucial role in the fertilization process by facilitating the penetration of the egg's protective layers, making choice D the correct answer.

While giving a history, the patient reports having herpes genitalis. Based on this information, which finding does the nurse anticipate during the assessment?

  • A. Small vesicles on the genitalia
  • B. Single, firm, painless, open sore
  • C. Pain when palpating the cervix
  • D. Malodorous greenish-yellow vaginal discharge
Correct Answer: A

Rationale: The correct answer is A: Small vesicles on the genitalia. Genital herpes typically presents with small vesicles on the genitalia. These vesicles are usually painful and may be accompanied by itching or burning sensations. The presence of vesicles is a hallmark sign of genital herpes.

Summary:
B: Single, firm, painless, open sore is more characteristic of syphilis, not genital herpes.
C: Pain when palpating the cervix is not a typical finding in genital herpes.
D: Malodorous greenish-yellow vaginal discharge is more indicative of a bacterial infection like trichomoniasis, not genital herpes.

How long are the typical ovarian and uterine (menstrual) cycles in a female?

  • A. 7 days
  • B. 14 days
  • C. 28 days
  • D. 40 days
Correct Answer: C

Rationale: The correct answer is C (28 days) because the typical ovarian and uterine (menstrual) cycles in a female are both around this duration. The menstrual cycle is typically 28 days, with ovulation occurring around day 14. This cycle is regulated by hormonal fluctuations and prepares the uterus for potential pregnancy. Choices A, B, and D are incorrect because a 7-day cycle is too short for a full menstrual cycle, a 14-day cycle is typically the duration of ovulation, and a 40-day cycle is longer than the average menstrual cycle length.

Which of the following is a rounded, knuckle like bony process at the joint?

  • A. Trochanter
  • B. Tubercle
  • C. Tuberosity
  • D. Condyle
Correct Answer: D

Rationale: The correct answer is D: Condyle. A condyle is a rounded, knuckle-like bony process found at joints, typically for articulation with another bone. Trochanter (A) is a large, blunt bony process, typically found on the femur. Tubercle (B) is a small, rounded bony prominence. Tuberosity (C) is a large, rounded bony prominence for muscle attachment. Therefore, only condyle fits the description of a rounded bony process at a joint.

What structure corresponds to the scrotum in the male?

  • A. labia major
  • B. labia minor
  • C. pudendal cleft
  • D. mons pubis
Correct Answer: A

Rationale: The correct answer is A: labia major. The scrotum in males corresponds to the labia major in females as they both serve as protective structures for the reproductive organs. The labia major in females is analogous to the scrotum in males in terms of function and location. The other choices are incorrect because the labia minor (B) is a smaller structure located inside the labia major, the pudendal cleft (C) refers to the space between the labia major and labia minor, and the mons pubis (D) is a rounded, fatty area located over the pubic bone.
