Nursing Elites

1. Differentiate between epithelial and connective tissue.

• A. Epithelial tissue is exclusively found in the lungs, while connective tissue supports tendons.
• B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
• C. Epithelial tissue is more vascularized, while connective tissue is responsible for muscle contraction.
• D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.

2. What is the name for the flexible connection between bones at the wrist or ankle?

• A. Ligament
• B. Tendon
• C. Fascia
• D. Synovial joint

Correct answer: A

Rationale: The correct answer is A: Ligament. Ligaments are fibrous connective tissues that connect bones to other bones, providing stability and support to joints. In the context of the wrist or ankle, ligaments play a crucial role in maintaining the structural integrity of these joints and preventing excessive movement that could lead to injury. Tendons (option B) connect muscles to bones, fascia (option C) is a connective tissue that surrounds muscles and other structures, and synovial joint (option D) refers to a type of joint that allows for movement. Therefore, the flexible connection between bones at the wrist or ankle is best described as a ligament.

3. Which part of the brain is responsible for regulating body temperature, hunger, and thirst, and is considered a key player in the endocrine system?

• A. Amygdala
• B. Hippocampus
• C. Hypothalamus
• D. Thalamus

Correct answer: c

Rationale: The correct answer is C: Hypothalamus. The hypothalamus is a small region in the brain that plays a crucial role in maintaining homeostasis by regulating body temperature, hunger, and thirst. It also serves as a key player in the endocrine system by controlling the release of hormones from the pituitary gland. The amygdala is responsible for processing emotions and memory, the hippocampus is involved in memory formation and retrieval, and the thalamus acts as a relay station for sensory information. Therefore, the hypothalamus is the most appropriate choice for the functions described in the question.

4. What property of a substance refers to its ability to undergo a chemical change and form new substances?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

5. What principle explains the relationship between pressure, volume, and temperature for ideal gases?

• A. Law of conservation of energy
• B. Newton's laws of motion
• C. Ideal gas law
• D. Archimedes' principle

Correct answer: C

Rationale: The ideal gas law (PV = nRT) relates pressure, volume, and temperature for ideal gases at constant number of moles and temperature.

6. Distinguish between the digestive and respiratory systems.

• A. Mouth
• B. Stomach
• C. Small intestine
• D. Lungs

Correct answer: D

Rationale: Rationale: - The mouth, stomach, and small intestine are all parts of the digestive system, responsible for breaking down food into nutrients that can be absorbed by the body. - The lungs are part of the respiratory system, responsible for the exchange of oxygen and carbon dioxide between the body and the environment through breathing. - While the digestive system processes food for energy and nutrients, the respiratory system is focused on the exchange of gases necessary for cellular respiration.
