Which of the following changes would be expected to occur with increased binding of a hormone to plasma proteins?

  • A. Increase in plasma clearance of the hormone
  • B. Decrease in half-life of the hormone
  • C. Increase in hormone activity
  • D. Increase in degree of negative feedback exerted by the hormone
Correct Answer: D

Rationale: Step 1: Increased binding of a hormone to plasma proteins reduces the concentration of free hormone in the blood.
Step 2: With decreased free hormone levels, there is less hormone available to exert its effects.
Step 3: This reduction in free hormone would lead to an increase in the degree of negative feedback exerted by the hormone to regulate its own production.
Therefore, the correct answer is D.

Summary:
A: Increase in plasma clearance of the hormone - Incorrect. Increased binding to plasma proteins would decrease clearance.
B: Decrease in half-life of the hormone - Incorrect. Increased binding can prolong the half-life by protecting the hormone from degradation.
C: Increase in hormone activity - Incorrect. Increased binding reduces the availability of free hormone, decreasing its activity.

Where does fertilization normally take place?

  • A. Uterus
  • B. Cervix
  • C. Ovary
  • D. Ampulla of the fallopian tubes
Correct Answer: D

Rationale: The correct answer is D: Ampulla of the fallopian tubes. Fertilization typically occurs in the ampulla of the fallopian tubes, where the sperm meets the egg. The ampulla is the widest part of the fallopian tube, providing the necessary space for fertilization to occur. Sperm must travel through the cervix and uterus to reach the fallopian tubes where fertilization takes place. The ovary is where the egg is released during ovulation but fertilization occurs in the fallopian tubes.

The egg is fertilized in which anatomical structure?

  • A. Vagina
  • B. Uterus
  • C. uterine (fallopian) tube
  • D. cervix
Correct Answer: B

Rationale: The correct answer is B: Uterus. After fertilization, the egg travels through the fallopian tube and implants in the uterus for further development. The vagina is the birth canal, not the site of fertilization. The fallopian tube is where fertilization typically occurs, but the actual implantation of the fertilized egg occurs in the uterus. The cervix is the lower part of the uterus that connects to the vagina and plays a role in pregnancy but is not where fertilization occurs.

Which of these is not a function of testosterone?

  • A. loss of body hair
  • B. thickening of the larynx
  • C. anabolism of skeletal muscle
  • D. thickening of bones
Correct Answer: A

Rationale: The correct answer is A, loss of body hair. Testosterone is responsible for thickening of the larynx, anabolism of skeletal muscle, and thickening of bones. It promotes growth and development of male secondary sexual characteristics, such as increased body hair. Therefore, loss of body hair is not a function of testosterone. Choice B, thickening of the larynx, is correct because testosterone contributes to the deepening of the voice by thickening the vocal cords. Choice C, anabolism of skeletal muscle, is correct as testosterone enhances protein synthesis in muscles, leading to muscle growth. Choice D, thickening of bones, is correct because testosterone promotes bone growth and mineralization.

During a history, a patient reports rectal bleeding, a warning sign of colorectal cancer. The nurse correlates which clinical finding with colorectal cancer?

  • A. Thick, blood-tinged mucus within the rectum
  • B. A pus-filled cavity in the anorectal area
  • C. An irregular mass with raised edges on the rectal wall
  • D. A small, smooth nodule protruding from the rectum
Correct Answer: C

Rationale: The correct answer is C because an irregular mass with raised edges on the rectal wall is a common clinical finding associated with colorectal cancer. This mass could be a tumor or polyp, which can lead to rectal bleeding. Option A is incorrect because thick, blood-tinged mucus is more commonly associated with inflammatory conditions. Option B is incorrect as a pus-filled cavity suggests an abscess or infection, not colorectal cancer. Option D is incorrect because a small, smooth nodule is more indicative of hemorrhoids rather than colorectal cancer.

The hormone(s) responsible for hymen. secondary sex characteristics in

  • A. The vagina is the female females is/are ________.
  • B. estrogens
  • C. The innermost lining of the
  • D. progesterone
Correct Answer: B

Rationale: The correct answer is B: estrogens. Estrogens are the primary hormones responsible for the development of secondary sex characteristics in females, including the formation of the hymen. Estrogens play a crucial role in regulating menstrual cycles, breast development, and overall reproductive health in females. Progesterone (choice D) is primarily involved in regulating the menstrual cycle and supporting pregnancy but is not directly responsible for hymen development. Choices A and C do not provide accurate or relevant information related to the development of secondary sex characteristics or the hymen.
