The external female reproductive organs include

  • A. the vagina, the clitoris, and the mons pubis
  • B. the hymen, the vaginal opening, and the uterus
  • C. the vaginal opening, the labia majora, and the clitoris
  • D. the hymen, the ovaries, and the clitoris
Correct Answer: C

Rationale: The correct answer is C because the external female reproductive organs typically include the vaginal opening, the labia majora, and the clitoris. The vaginal opening is where sperm enters and a baby exits during childbirth. The labia majora are the outer folds of skin that protect the vaginal and urethral openings. The clitoris is a highly sensitive sexual organ that plays a key role in sexual pleasure.

Option A is incorrect because it includes the mons pubis, which is not considered an external reproductive organ. Option B is incorrect because it includes the hymen, which is a thin membrane that may partially cover the vaginal opening but is not a consistent external organ. Option D is incorrect because it includes the ovaries, which are internal organs responsible for producing eggs, not external reproductive organs.

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.

Spermatogenesis is a function of the _____.

  • A. tunica albuginea
  • B. rete testis
  • C. seminiferous tubule
  • D. seminal vesicle
Correct Answer: C

Rationale: The correct answer is C: seminiferous tubule. Spermatogenesis is the process of sperm production and occurs within the seminiferous tubules of the testes. These tubules contain specialized cells called germ cells that undergo meiosis to produce sperm. The tunica albuginea is a fibrous layer surrounding the testes, the rete testis is a network of tubules where sperm is transported, and the seminal vesicle is a gland that produces seminal fluid, not involved in sperm production. Therefore, the seminiferous tubule is the correct choice for spermatogenesis.

Parturition occurs the fetus is the ________. approximately how many days after a

  • A. amnion woman's last menstrual cycle ______.
  • B. placenta
  • C. 180 days
  • D. chorionic villi
Correct Answer: D

Rationale: The correct answer is D: chorionic villi. Parturition occurs when the fetus releases cortisol, which stimulates the production of prostaglandins leading to uterine contractions. Chorionic villi are the fetal tissue that produces cortisol, making it the key factor triggering labor.
A: Amnion is the innermost membrane around the fetus, not directly involved in labor initiation.
B: Placenta plays a role in nutrient exchange but not in triggering labor.
C: 180 days is a set time frame and does not relate to the process of parturition.

  • A. Obtain a paracentesis tray from the central supply area.
  • B. Complete the short-stay client admission form.
  • C. Take vital signs every 15 minutes after the procedure.

Which hormone is produced by the corpus luteum that helps maintain pregnancy?

  • A. Estrogen
  • B. Testosterone
  • C. Progesterone
  • D. Relaxin
Correct Answer: C

Rationale: The correct answer is C: Progesterone. The corpus luteum produces progesterone, which is essential for maintaining the uterine lining and supporting early pregnancy. Progesterone helps prevent contractions of the uterus and supports the development of the placenta. Estrogen (A) is important for the initial thickening of the uterine lining but does not play a direct role in maintaining pregnancy. Testosterone (B) is not involved in pregnancy maintenance. Relaxin (D) helps relax the uterine muscles but is not primarily responsible for maintaining pregnancy.
