Question 1 of 5
Giving prostaglandin E2 (PGE2) to a pregnant woman may result in an abortion. What is the best explanation for this finding?
Correct Answer: A
Rationale: The correct answer is A because prostaglandin E2 (PGE2) is known to strongly stimulate uterine contractions. This can lead to abortion by triggering premature labor and causing the expulsion of the fetus. Choice B is incorrect as PGE2 does not cause arterial constriction leading to the placenta. Choice C is incorrect because PGE2 does not stimulate the release of oxytocin; rather, oxytocin itself is a hormone that stimulates uterine contractions. Choice D is also incorrect as PGE2 does not increase progesterone secretion from the corpus luteum; in fact, PGE2 can have the opposite effect by inhibiting progesterone synthesis.
Question 2 of 5
Failure of the ductus arteriosus to close is a common developmental defect. Which of the following would likely be present in a 12-month-old infant with patent ductus arteriosus?
Correct Answer: A
Rationale: The correct answer is A: Below-normal arterial PO2. In a 12-month-old infant with patent ductus arteriosus, there would likely be a left-to-right shunt causing increased blood flow to the lungs, leading to decreased systemic blood flow. This can result in decreased systemic oxygenation and below-normal arterial PO2 levels. Choices B, C, and D are incorrect because patent ductus arteriosus does not directly affect arterial PCO2, arterial blood pressure, or pulmonary arterial pressure in a way that would lead to those specific outcomes at this age.
Question 3 of 5
Which gland provides fructose, a sugar in semen that energizes sperm?
Correct Answer: A
Rationale: The correct answer is A: Seminal vesicles. These glands produce fructose, a sugar in semen that provides energy for sperm. Seminal vesicles are located near the base of the bladder and are responsible for producing a significant portion of the fluid in semen. The other choices are incorrect because the bulbourethral gland produces a clear lubricating fluid, the prostate produces a milky fluid that helps with sperm motility and viability, and the epididymis is a coiled tube where sperm mature and are stored, but it does not produce fructose.
Question 4 of 5
Where are sperm produced within a male's testis?
Correct Answer: A
Rationale: The correct answer is A: Seminiferous tubules. Sperm production occurs in the seminiferous tubules of the testis through a process called spermatogenesis. This is where germ cells develop into mature spermatozoa. The other choices are incorrect: B: Ejaculatory duct is where sperm and seminal fluid mix before ejaculation, C: Interstitial cells produce testosterone, and D: Rete testis is a network of tubules where sperm travel after being produced in the seminiferous tubules.
Question 5 of 5
The process by which a secondary oocyte is ejected from the ovary is called ________.
Correct Answer: D
Rationale: The correct answer is D: ovulation. This process involves the release of a mature egg (secondary oocyte) from the ovarian follicle. During ovulation, the egg is released into the fallopian tube, where it can potentially be fertilized by sperm. A: emission - Incorrect. This term typically refers to the discharge of semen from the male reproductive system. B: menses - Incorrect. Menses refers to the shedding of the uterine lining during menstruation, not the release of an egg from the ovary. C: fertilization - Incorrect. Fertilization is the process of the sperm uniting with the egg, which occurs in the fallopian tube after ovulation.
