Which hormone is primarily responsible for maintaining the corpus luteum and supporting the early stages of pregnancy?

  1. Estrogen

  2. Progesterone

  3. Human Chorionic Gonadotropin (hCG)

  4. Prolactin


Correct Option: B
Explanation:

Progesterone plays a crucial role in maintaining the corpus luteum, which produces progesterone and estrogen necessary for the early stages of pregnancy.

What is the primary function of human chorionic gonadotropin (hCG) during pregnancy?

  1. Stimulates the ovaries to produce estrogen and progesterone

  2. Maintains the corpus luteum

  3. Promotes the development of the placenta

  4. Increases blood flow to the uterus


Correct Option: B
Explanation:

hCG primarily maintains the corpus luteum, which continues to produce progesterone and estrogen essential for the early stages of pregnancy.

Which hormone is responsible for stimulating milk production in the mammary glands?

  1. Estrogen

  2. Progesterone

  3. Prolactin

  4. Oxytocin


Correct Option: C
Explanation:

Prolactin is the primary hormone responsible for stimulating milk production in the mammary glands during pregnancy and after childbirth.

What is the primary role of estrogen during pregnancy?

  1. Stimulates the growth of the uterus

  2. Promotes the development of the placenta

  3. Increases blood flow to the uterus

  4. Prepares the breasts for lactation


Correct Option: A
Explanation:

Estrogen plays a crucial role in stimulating the growth of the uterus to accommodate the developing fetus.

Which hormone is responsible for triggering uterine contractions during labor?

  1. Estrogen

  2. Progesterone

  3. Prolactin

  4. Oxytocin


Correct Option: D
Explanation:

Oxytocin is the primary hormone responsible for triggering uterine contractions during labor, leading to the birth of the baby.

What is the most common endocrine disorder during pregnancy?

  1. Gestational Diabetes

  2. Hypothyroidism

  3. Hyperthyroidism

  4. Cushing's Syndrome


Correct Option: A
Explanation:

Gestational Diabetes is the most common endocrine disorder during pregnancy, characterized by high blood sugar levels due to insulin resistance.

Which hormone is responsible for regulating calcium and phosphate metabolism during pregnancy?

  1. Estrogen

  2. Progesterone

  3. Parathyroid Hormone (PTH)

  4. Calcitonin


Correct Option: C
Explanation:

Parathyroid Hormone (PTH) plays a crucial role in regulating calcium and phosphate metabolism during pregnancy, ensuring adequate calcium levels for both the mother and the developing fetus.

What is the primary cause of pre-eclampsia, a pregnancy-related condition characterized by high blood pressure and protein in the urine?

  1. Placental Abruption

  2. Uterine Rupture

  3. Gestational Diabetes

  4. Inadequate Placental Perfusion


Correct Option: D
Explanation:

Pre-eclampsia is primarily caused by inadequate placental perfusion, leading to abnormal development of the placenta and subsequent complications.

Which hormone is responsible for stimulating the release of breast milk during breastfeeding?

  1. Estrogen

  2. Progesterone

  3. Prolactin

  4. Oxytocin


Correct Option: D
Explanation:

Oxytocin is the primary hormone responsible for stimulating the release of breast milk during breastfeeding, also known as the let-down reflex.

What is the primary role of the placenta during pregnancy?

  1. Provides oxygen and nutrients to the fetus

  2. Removes waste products from the fetus

  3. Produces hormones essential for pregnancy

  4. All of the above


Correct Option: D
Explanation:

The placenta plays a crucial role in providing oxygen and nutrients to the fetus, removing waste products, and producing hormones essential for maintaining pregnancy.

Which hormone is responsible for increasing blood volume and cardiac output during pregnancy?

  1. Estrogen

  2. Progesterone

  3. Human Chorionic Gonadotropin (hCG)

  4. Prolactin


Correct Option: B
Explanation:

Progesterone is primarily responsible for increasing blood volume and cardiac output during pregnancy to meet the increased demands of the growing fetus.

What is the primary function of thyroid hormones during pregnancy?

  1. Regulate metabolism

  2. Promote fetal brain development

  3. Stimulate bone growth

  4. Maintain electrolyte balance


Correct Option: B
Explanation:

Thyroid hormones play a crucial role in promoting fetal brain development, particularly during the early stages of pregnancy.

Which hormone is responsible for preparing the breasts for lactation during pregnancy?

  1. Estrogen

  2. Progesterone

  3. Prolactin

  4. Oxytocin


Correct Option: C
Explanation:

Prolactin is primarily responsible for preparing the breasts for lactation during pregnancy, stimulating the growth of milk-producing glands.

What is the primary role of insulin during pregnancy?

  1. Regulate blood sugar levels

  2. Promote fetal growth

  3. Stimulate milk production

  4. Maintain electrolyte balance


Correct Option: A
Explanation:

Insulin plays a crucial role in regulating blood sugar levels during pregnancy, ensuring adequate glucose supply to both the mother and the developing fetus.

Which hormone is responsible for stimulating uterine contractions during labor?

  1. Estrogen

  2. Progesterone

  3. Prolactin

  4. Oxytocin


Correct Option: D
Explanation:
