-Identify the hormone labeled "4."
A) thyroid-releasing hormone
B) thyroid-stimulating hormone
C) thyroxin
D) thyrotropin

The primary function of ADH is to
A) increase the amount of sodium lost at the kidneys.
B) decrease the amount of water lost at the kidneys.

Question 8

Figure 16-1 Pituitary Hormones and Their Targets
Use Figure 16-1 to answer the following questions:
-Identify the hormone labeled " 1."
A) mineralocorticoid
B) cortisol
C) dopamine
D) corticotropin (ACTH)
E) aldosterone

Accepted Answer

The hormone labeled "1" is corticotropin (ACTH), which stimulates the release of cortisol from the adrenal gland.

Question 9

TSH plays a key role in the ________ of thyroid hormones.
A) inhibition
B) synthesis
C) release
D) inhibition and synthesis
E) synthesis and release

Accepted Answer

TSH stimulates the synthesis and release of thyroid hormones from the thyroid gland.

Question 10

After brain surgery, a patient receiving postoperative care in an intensive care unit began to pass large volumes of very dilute urine. The ICU nurse administered a medicine that mimics one of the following hormones. Which one?
A) aldosterone
B) epinephrine
C) renin
D) ADH
E) cortisol

Accepted Answer

The patient is experiencing diabetes insipidus, a condition where the body doesn't produce enough of the antidiuretic hormone (ADH) to regulate water balance in the body. The nurse would administer a medication that mimics ADH, such as desmopressin, to treat the condition. None of the other hormones listed are directly related to water balance regulation.

Question 11

The pituitary hormone that stimulates milk production by the mammary glands is
A) TSH.
B) ACTH.
C) growth hormone.
D) FSH.
E) prolactin.

Accepted Answer

Prolactin is the hormone produced by the anterior pituitary gland that stimulates milk production by the mammary glands.

Question 12

Which of the following is not an action of TSH?
A) stimulates T₃ and T₄ secretion
B) stimulates iodide trapping by thyroid follicle cells
C) inhibits T₃ and T₄ secretion
D) stimulates pinocytosis of colloid by thyroid follicle cells
E) increases cyclic AMP concentration within thyroid follicle cells

Accepted Answer

TSH is a hormone secreted by the anterior pituitary gland that stimulates the thyroid gland to produce and secrete T3 and T4 hormones. Therefore, option A is correct. TSH also stimulates iodide trapping and pinocytosis of colloid by thyroid follicle cells, which are necessary for the synthesis of T3 and T4 hormones. Therefore, options B and D are correct. TSH increases cyclic AMP concentration within thyroid follicle cells, which is necessary for hormone synthesis and secretion. Therefore, option E is correct. Option C is incorrect because TSH does not inhibit T3 and T4 secretion.

Question 13

The pituitary hormone that causes the kidney to reduce water loss is
A) TSH.
B) FSH.
C) MSH.
D) STH.
E) ADH.

Accepted Answer

The hormone that causes the kidney to reduce water loss is antidiuretic hormone (ADH), also known as vasopressin, which is produced by the hypothalamus and released by the posterior pituitary gland. ADH increases water reabsorption in the kidneys, reducing urine output and helping to maintain fluid balance in the body. TSH (thyroid-stimulating hormone) stimulates the thyroid gland to produce thyroid hormones, FSH (follicle-stimulating hormone) stimulates the growth and maturation of ovarian follicles in females and sperm production in males, MSH (melanocyte-stimulating hormone) regulates skin pigmentation and some physiological processes, and STH (somatotropic hormone or growth hormone) promotes growth and development in children and regulates metabolism in adults. None of these hormones have a direct effect on water regulation in the body.

Question 14

The pituitary hormone that promotes egg development in ovaries and sperm development in testes is
A) TSH.
B) ACTH.
C) FSH.
D) LH.
E) GH.

Accepted Answer

FSH, or Follicle-Stimulating Hormone, is responsible for the growth of ovarian follicles in females and the production of sperm in males.

Question 16

The ovaries secrete ________ when stimulated by FSH.
A) estrogen
B) progesterone
C) testosterone
D) oxytocin
E) gonadotropins

Accepted Answer

The ovaries secrete estrogen when stimulated by FSH.

Question 17

The pituitary hormone that stimulates cell growth and replication by accelerating protein synthesis is
A) ACTH.
B) MSH.
C) prolactin.
D) insulin.
E) growth hormone.

Accepted Answer

Growth hormone (GH), also called somatotropin, stimulates cell growth and replication by accelerating protein synthesis. GH plays an important role in overall growth, development, and maintenance of the body.

Question 18

Changes in blood osmotic pressure would most affect the secretion of
A) ACTH.
B) ADH.
C) oxytocin.
D) TSH.
E) LH.

Accepted Answer

Blood osmotic pressure is directly related to the amount of water in the blood. When blood osmotic pressure increases (indicating a decrease in water volume), the secretion of antidiuretic hormone (ADH) increases. ADH promotes water retention in the body, reducing urine output and increasing blood volume. Therefore, changes in blood osmotic pressure would most affect the secretion of ADH.

Question 19

The testes produce
A) LH.
B) progesterone.
C) testosterone.
D) inhibin.
E) FSH.

Accepted Answer

The testes primarily produce testosterone, which is responsible for the development and maintenance of male reproductive tissues and secondary sexual characteristics. The other hormones listed (LH, FSH, progesterone, and inhibin) are produced by various other organs in the endocrine system.

Question 20

The hormone(s) that may be slowly administered by intravenous drip to accelerate labor and delivery is (are)
A) oxytocin.
B) prolactin.
C) luteinizing hormone.
D) just extra fluids.
E) oxytocin and luteinizing hormone.

Accepted Answer

Oxytocin is the hormone that is commonly administered by intravenous drip to accelerate labor and delivery. It stimulates uterine contractions and can help shorten the labor process. Prolactin is involved in milk production, not labor and delivery, while luteinizing hormone plays a role in the menstrual cycle and ovulation. Extra fluids alone would not be used to accelerate labor and delivery.
