Nursing Elites

1. What is the difference between mass and weight?

• A. Mass is the force exerted on an object due to gravity, whereas weight is the amount of matter in an object.
• B. Mass is a measure of inertia, whereas weight is a measure of the force of gravity acting on an object.
• C. Mass is measured in pounds, whereas weight is measured in kilograms.
• D. Mass is a vector quantity, whereas weight is a scalar quantity.

Correct answer: b

Rationale: Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

2. What is the protective fluid that surrounds the brain and spinal cord?

• A. Blood
• B. Cerebrospinal fluid
• C. Myelin sheath
• D. Insulin

Correct answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. This fluid acts as a cushion for the brain and spinal cord, providing protection from impacts. Blood is essential for transporting nutrients and oxygen, but it does not directly surround or protect these vital nervous system structures. Myelin sheath is a fatty substance that insulates nerve fibers, not the fluid surrounding the nervous system. Insulin is a hormone involved in regulating blood sugar levels and is not related to protecting the brain and spinal cord.

3. She takes pride in saying that the hospital has a decentralized structure. Which of the

• A. Flat organization
• B. Participatory approach
• C. Shared governance
• D. Tall organization

Correct answer: B

Rationale: The correct answer is B: 'Participatory approach.' In a decentralized structure, decision-making authority is dispersed throughout the organization rather than being concentrated at the top. A participatory approach involves employees at all levels having a say in decisions that affect their work, fostering collaboration and empowerment. This contrasts with a tall organization, which has many layers of management and a more centralized decision-making process. While shared governance can involve decentralized decision-making, it specifically refers to a model where nurses and other healthcare professionals have a voice in shaping policies and practices within their organization, which is not necessarily the same as a decentralized structure.

4. Balance the chemical equation: C4H10 + O2 → CO2 + H2O. What is the coefficient for oxygen?

• A. 5
• B. 6
• C. 7
• D. 8

Correct answer: b

Rationale: The balanced equation is C4H10 + 6O2 → 4CO2 + 5H2O.

5. A medication order is written as 3/4 of a tablet. If each tablet is 500mg, what is the equivalent dosage in milligrams?

• A. 375mg
• B. 425mg
• C. 450mg
• D. 475mg

Correct answer: A

Rationale: Multiply the tablet strength (500mg) by the fractional dose (3/4) to get 375 milligrams.

6. Which of the following is NOT a factor affecting the rate of a chemical reaction?

• A. Concentration of reactants
• B. Temperature
• C. Presence of a catalyst
• D. Color of the reaction mixture

Correct answer: D

Rationale: Color of the reaction mixture. While color change can sometimes be an indicator of a reaction, it doesn't directly influence the reaction rate.
