Example Questions

Example Question #81 : Understanding Other Reproductive Physiology

Which of the following is a method used to induce labor?

Possible Answers:

Administering prostaglandins to dilate the cervix

Nipple stimulation

Artificially rupturing the amniotic sac

None of these

All of these

Correct answer:

All of these

Explanation:

In cases of maternal or fetal complications, labor may be medically induced. These methods typically aim to trigger the body to naturally begin labor. They include artificially rupturing the amniotic sac (“breaking the water”), nipple stimulation, and administering prostaglandins.

Example Question #82 : Understanding Other Reproductive Physiology

Which of the following parts of the female body is where the fetus is surgically removed during caesarian sections?

Possible Answers:

Uterus

Vagina

Uterine wall

Birth canal

None of these

Correct answer:

Uterus

Explanation:

A caesarian section is a method to deliver the fetus surgically. During the procedure, an incision is made in the mother’s abdomen and uterus to remove the fetus. Caesarian sections are used in the case of pregnancy and labor complications, but they can also be undertaken electively.

Example Question #83 : Understanding Other Reproductive Physiology

Which of the following is a technological development targeted at improved care for premature infants?

Possible Answers:

Skin-skin contact

All of these

Pain medications

Incubation in neonatal intensive care units

Caesarian sections

Correct answer:

Incubation in neonatal intensive care units

Explanation:

Neonatal intensive care units are highly developed and specialized units that house premature infants. These units provide the following advances in neonatal care: temperature regulation, protection, nutrition, and the administration of medications.

Example Question #84 : Understanding Other Reproductive Physiology

Which of the following is true regarding postpartum depression?

Possible Answers:

No clinical evidence of postpartum depression has been found

It can interfere with mother-infant bonding

None of these

It is only recognized by western civilizations

It only occurs during pregnancy

Correct answer:

It can interfere with mother-infant bonding

Explanation:

Postpartum depression is a condition that may occur in women that have recently given birth. It is a type of clinical depression that is recognized by the medical community and is found in mothers all over the world. Symptoms of postpartum depression include low energy, anxiety, and mood changes. Postpartum depression may interfere with mother-infant bonding. Methods to prevent postpartum depression include peer support and antidepressants.

Example Question #85 : Understanding Other Reproductive Physiology

Which of the following best describes the role of oxytocin in delivery?

Possible Answers:

Directly releases the cervical mucus plug

All of these

Prevents cervical dilation

Stimulates the expulsion of the fetus

High levels increase the risk for postpartum depression

Correct answer:

Stimulates the expulsion of the fetus

Explanation:

During childbirth, oxytocin stimulates fetal expulsion through cervical dilation and uterine contractions. Oxytocin is also important in the development of maternal feelings of attachment to the fetus and plays a role in lactation.

Example Question #86 : Understanding Other Reproductive Physiology

Which of the following is a method of instrumental child delivery?

Possible Answers:

Vacuum extraction

Forceps

Labor induction via prostaglandins

Pliers

Vacuum extraction and forceps

Correct answer:

Vacuum extraction and forceps

Explanation:

Instrumental delivery is the delivery of an infant through the use of medical instruments. This is used in the case of difficult deliveries and labor complications. Instruments that are commonly used include the vacuum extractor and forceps.

Example Question #87 : Understanding Other Reproductive Physiology

Which of the following hormones is not involved in the menstrual cycle?

Possible Answers:

Prolactin

Follicle-stimulating hormone (FSH)

Luteinizing hormone (LH)

Estrogen

Progesterone

Correct answer:

Prolactin

Explanation:

Prolactin is a hormone responsible for the production of milk in the mammary glands of mammals. It is not involved in the menstrual cycle, which is controlled by fluctuating levels of the hormones estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).

Example Question #394 : Systems Physiology

Which of the following can be defined as the process by which sperm is discharged from the male body?

Possible Answers:

None of these

menstruation

Oogenesis

Spermatogenesis

Ejaculation

Correct answer:

Ejaculation

Explanation:

Ejaculation is defined as the process by which sperm is discharged from the male body through the urethra. This process typically occurs during the male orgasm.

Example Question #88 : Understanding Other Reproductive Physiology

Which of the following correctly identifies the typical—average—length of a single female menstrual cycle?

Possible Answers:

Correct answer:

Explanation:

One average, one menstrual cycle typically lasts for about 28 days; however, this time length can range anywhere from 21 to 35 days depending on the individual.

Example Question #89 : Understanding Other Reproductive Physiology

What hormone causes ovulation to occur during the menstrual cycle?

Possible Answers:

Prolactin

Follicle-stimulating hormone

Luteinizing hormone

Growth hormone

Thyroid-stimulating hormone

Correct answer:

Luteinizing hormone

Explanation:

An increase in estrogen causes an increase in the luteinizing hormone. It is the luteinizing hormone that causes ovulation. Ovulation is the process of releasing an ovum. 

Growth hormone creates growth in the body. Follicle-stimulating hormone helps follicles mature, and promotes spermatogenesis in males. Prolactin causes the mammary glands to create milk. Thyroid-stimulating hormone helps release thyroxine and triiodothyronine (thyroid hormones).
