Review these Reproductive Health and Prenatal Development – Quiz 2 nursing practice questions with answer choices and explanations.
Which hormone is primarily responsible for triggering ovulation during the menstrual cycle?
Correct answer:
Explanation: A surge in luteinizing hormone (LH) triggers ovulation by causing the mature follicle to release the ovum.
Which structure transports the ovum from the ovary to the uterus?
Correct answer:
Explanation: The fallopian tubes transport the ovum from the ovary to the uterus and are the usual site of fertilization.
Which hormone maintains pregnancy during the first trimester until the placenta develops?
Correct answer:
Explanation: Human chorionic gonadotropin (hCG) maintains the corpus luteum during early pregnancy so progesterone production continues.
Which layer of the uterus is shed during menstruation?
Correct answer:
Explanation: The endometrium is the inner lining of the uterus and is shed during menstruation if pregnancy does not occur.
Which hormone stimulates milk production after childbirth?
Correct answer:
Explanation: Prolactin stimulates milk production in the mammary glands following childbirth.
Which hormone is responsible for uterine contractions during labor?
Correct answer:
Explanation: Oxytocin stimulates uterine contractions during labor and also assists with milk ejection during breastfeeding.
Which organ produces ova in females?
Correct answer:
Explanation: The ovaries produce ova and release them during ovulation.
Which structure connects the uterus to the vagina?
Correct answer:
Explanation: The cervix is the lower portion of the uterus that opens into the vagina.
Which structure stores sperm before ejaculation?
Correct answer:
Explanation: The epididymis stores and matures sperm before they travel through the vas deferens.
What is the typical length of a normal menstrual cycle?
Correct answer:
Explanation: The average menstrual cycle length is about 28 days, although normal cycles can vary.
Which part of the sperm contains genetic material?
Correct answer:
Explanation: The head of the sperm contains the nucleus, which carries genetic material.
Which phase of the menstrual cycle follows ovulation?
Correct answer:
Explanation: The luteal phase occurs after ovulation and is characterized by progesterone secretion.
Which nutrient is most important for preventing neural tube defects during pregnancy?
Correct answer:
Explanation: Folic acid is essential during early pregnancy to prevent neural tube defects.
Which structure nourishes and protects the developing fetus during pregnancy?
Correct answer:
Explanation: The placenta provides oxygen and nutrients to the fetus and removes waste products.
Which structure produces seminal fluid that nourishes sperm?
Correct answer:
Explanation: Seminal vesicles produce nutrient-rich seminal fluid that supports sperm.
Which contraceptive method works by preventing ovulation?
Correct answer:
Explanation: Oral contraceptives suppress ovulation through hormonal regulation.
Which structure produces testosterone?
Correct answer:
Explanation: The testes produce testosterone, the primary male sex hormone.
Which hormone prepares the uterus for pregnancy?
Correct answer:
Explanation: Progesterone thickens and maintains the uterine lining for implantation.
Which structure surrounds and protects the fetus with fluid?
Correct answer:
Explanation: The amniotic sac contains amniotic fluid that cushions and protects the fetus.
Which stage of labor involves full cervical dilation?
Correct answer:
Explanation: The second stage of labor begins when the cervix is fully dilated and ends with the birth of the baby.
Which organ temporarily supports the fetus during pregnancy?
Correct answer:
Explanation: The placenta functions as the interface for oxygen, nutrients, and waste exchange between mother and fetus.
Which structure connects the fetus to the placenta?
Correct answer:
Explanation: The umbilical cord carries blood between the fetus and placenta.
Which hormone stimulates the release of milk during breastfeeding?
Correct answer:
Explanation: Oxytocin triggers the milk ejection reflex during breastfeeding.
Which term describes the fertilized egg before implantation?
Correct answer:
Explanation: The fertilized egg is called a zygote before it implants in the uterus.
Which hormone stimulates development of ovarian follicles?
Correct answer:
Explanation: Follicle-stimulating hormone promotes follicle development in the ovaries.
Which part of the uterus contracts during labor?
Correct answer:
Explanation: The myometrium is the muscular layer of the uterus responsible for contractions.
Which male structure carries sperm during ejaculation?
Correct answer:
Explanation: The vas deferens transports sperm from the epididymis to the urethra.
Which hormone increases near ovulation to cause cervical mucus thinning?
Correct answer:
Explanation: Estrogen causes cervical mucus to become thin and stretchy, facilitating sperm movement.
Which stage follows the embryonic stage of development?
Correct answer:
Explanation: After the embryonic stage (first 8 weeks), development enters the fetal stage.
Which reproductive structure produces ova monthly?
Correct answer:
Explanation: The ovaries release one ovum each menstrual cycle during ovulation.
Which hormone maintains uterine lining during pregnancy?
Correct answer:
Explanation: Progesterone maintains the endometrium to support pregnancy.
