1. What property of matter refers to the amount of space occupied by an object?

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

Correct answer: b

Rationale: Volume measures the amount of space occupied by an object.

2. A spring is stretched and released, causing an object attached to it to oscillate. What determines the frequency of the oscillations?

• A. The mass of the object
• B. The stiffness of the spring
• C. The initial displacement of the object
• D. All of the above

Correct answer: B

Rationale: The stiffness of the spring. Frequency depends on the spring constant and the mass, but the mass term cancels out in the formula for simple harmonic motion, leaving only the spring constant.

3. What is the primary factor that determines whether a solute will dissolve in a solvent?

• A. Temperature
• B. Pressure
• C. Molecular structure
• D. Particle size

Correct answer: c

Rationale: The molecular structure of the solute and solvent plays a key role in determining solubility. The other choices may influence solubility but are not the primary determining factor.

4. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

• A. Molecule
• B. Atom
• C. Compound
• D. Mixture

Correct answer: A

Rationale: An atom is the fundamental building block of an element, consisting of a nucleus and electrons.

5. Which of the following is NOT typically found in healthy urine?

• A. Urea
• B. Glucose
• C. Creatinine
• D. Electrolytes

Correct answer: B

Rationale: Glucose is NOT typically found in healthy urine because the kidneys filter glucose from the blood, and any excess is excreted in the urine. In healthy individuals, the renal threshold for glucose reabsorption is low, so glucose should not be present in significant amounts in urine. On the other hand, urea, creatinine, and electrolytes are all normal components of urine. Urea is a waste product of protein metabolism, creatinine is a waste product of muscle metabolism, and electrolytes like sodium and potassium are essential for various bodily functions and are excreted in urine. Therefore, option B is the correct answer as glucose is not typically found in healthy urine.

6. Which of the following is TRUE about functional nursing?

• A. Concentrates on tasks and activities
• B. Emphasizes use of group collaboration
• C. One-to-one nurse-patient ratio
• D. Provides continuous, coordinated and comprehensive nursing services

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.
