Nursing Elites

1. The human body's largest organ, responsible for detoxification and a multitude of other functions, is the:

• A. Heart
• B. Liver
• C. Lungs
• D. Skin

Correct answer: B

Rationale: The correct answer is B: Liver. The liver is the largest internal organ in the human body and is responsible for detoxification, processing nutrients, producing bile, and regulating blood sugar levels, among other functions. While the heart is vital for pumping blood, the lungs are crucial for respiration, and the skin is the body's largest external organ, the liver plays a central role in detoxification and various metabolic processes, making it the correct answer to this question.

2. The stratified squamous epithelium found in the skin is adapted for:

• A. Absorption
• B. Secretion
• C. Protection
• D. Gas exchange

Correct answer: C

Rationale: The correct answer is C: Protection. Stratified squamous epithelium is a type of tissue that is well-suited for protection as it consists of multiple layers of cells that provide a barrier against physical and chemical damage. In the skin, this epithelium helps protect the body against external threats such as pathogens, UV radiation, and mechanical abrasion. Absorption (A) and secretion (B) are typically functions of other types of epithelial tissues, such as simple columnar or simple cuboidal epithelium. Gas exchange (D) is primarily facilitated by tissues like the alveolar epithelium in the lungs, not stratified squamous epithelium in the skin.

3. Which type of waves exhibit both longitudinal and transverse motion?

• A. Electromagnetic waves
• B. Surface waves
• C. Mechanical waves
• D. Sound waves

Correct answer: b

Rationale: Surface waves, like those on water surfaces, exhibit both longitudinal and transverse motion.

4. What is the difference between DNA and RNA?

• A. Both are double-stranded.
• B. DNA contains deoxyribose sugar, while RNA contains ribose sugar.
• C. RNA contains the nitrogenous base uracil, while DNA contains thymine.
• D. Both are identical molecules.

Correct answer: B

Rationale: Rationale: A) Incorrect. DNA is double-stranded, but RNA is typically single-stranded. B) Correct. DNA contains deoxyribose sugar, which lacks an oxygen atom on the 2' carbon of the sugar ring, while RNA contains ribose sugar, which has an additional hydroxyl group on the 2' carbon. C) Incorrect. RNA contains the nitrogenous base uracil, while DNA contains thymine. D) Incorrect. DNA and RNA have distinct structures and functions, so they are not identical molecules.

5. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

• A. Make an interpretation about strengths and weaknesses
• B. Identify the values of the department
• C. Identify structure, process, outcome standards & criteria
• D. Measure actual performances

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.

6. Identify the determiner in the following sentence: A few birds chirped happily in the branches of the tall tree.

• A. happily
