Nursing Elites

1. Classifications of human tissues exclude:

• A. Epithelial tissue
• B. Nervous tissue
• C. Adipose tissue (a specialized form of connective tissue)
• D. Bony tissue

Correct answer: D

Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.

2. Which type of waves travel by causing particles in the medium to vibrate parallel to the direction of wave travel?

• A. Transverse waves
• B. Longitudinal waves
• C. Surface waves
• D. Electromagnetic waves

Correct answer: B

Rationale: Longitudinal waves are waves in which particles of the medium vibrate parallel to the direction of wave travel. These waves are characterized by compressions and rarefactions in the medium, where particles move back and forth in the same direction as the wave. Transverse waves, on the other hand, cause particles to vibrate perpendicular to the direction of wave travel. Surface waves combine both longitudinal and transverse motion, making them different from pure longitudinal waves. Electromagnetic waves, unlike longitudinal and transverse waves, do not require a medium and can travel through a vacuum.

3. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

4. What type of joint is found in the shoulder and hip, allowing for a wide range of motion?

• A. Hinge joint
• B. Ball-and-socket joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is B: Ball-and-socket joint. A ball-and-socket joint, like those in the shoulder and hip, allows for a wide range of motion. In a ball-and-socket joint, the rounded end of one bone fits into the cup-like socket of another bone, enabling movement in multiple directions. Choice A, Hinge joint, is incorrect because hinge joints allow movement only in one plane, like a door hinge. Choice C, Pivot joint, is incorrect as it allows rotational movement around a single axis, not the wide range of motion seen in the shoulder and hip. Choice D, Saddle joint, is also incorrect as it allows movement in multiple directions but to a lesser extent compared to the ball-and-socket joint.

5. What is the muscular sac in the female body that nourishes and protects a developing fetus?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: C

Rationale: The correct answer is the uterus. The uterus is a muscular organ in the female body where a fertilized egg implants and grows into a fetus during pregnancy. It provides nourishment and protection to the developing fetus. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the muscular tube that connects the uterus to the outside of the body for childbirth. Therefore, the roles of the ovary, fallopian tube, and vagina are not related to nourishing and protecting a developing fetus, making them incorrect choices.
