physics
1. Which term refers to the resistance of a liquid to flow?
- A. Density
- B. Viscosity
- C. Surface tension
- D. Boiling point
Correct answer: B
Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is, and it determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume, surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, and boiling point (D) is the temperature at which a liquid changes to a vapor.
2. What is the role of the appendix, a small pouch attached to the large intestine?
- A. To store waste products
- B. To produce immune cells
- C. To secrete digestive enzymes
- D. To regulate blood sugar levels
Correct answer: B
Rationale: While the exact function of the appendix is still debated, it likely houses lymphoid tissue, contributing to the immune system.
3. What scientific term encompasses a permanent alteration in the DNA sequence?
- A. Trait
- B. Mutation
- C. Allele
- D. Variation
Correct answer: B
Rationale: Rationale: A) Trait: A trait is a characteristic or feature of an organism that is determined by its genes. B) Mutation: A mutation is a permanent alteration in the DNA sequence that can result from errors during DNA replication, exposure to mutagens, or other factors. C) Allele: An allele is a variant form of a gene that can result in different traits or characteristics. D) Variation: Variation refers to the differences in traits or characteristics among individuals of the same species, which can be influenced by genetic and environmental factors. In this context, the term that specifically refers to a permanent alteration in the DNA sequence is "mutation."
4. Colligative properties of solutions depend on the...
- A. Concentration of the solvent
- B. All of the 3 answers given
- C. Chemical identity of the solute
- D. Number of solute particles in solution
Correct answer: D
Rationale: The correct answer is D: 'Number of solute particles in solution.' Colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution, not on the chemical identity of the solute or the concentration of the solvent. This is because the presence of solute particles disrupts the solvent's normal behavior, affecting these properties. Therefore, the number of solute particles in solution directly influences colligative properties, making it the most accurate choice among the options provided.
5. Which type of energy is possessed by an object in motion?
- A. Potential energy
- B. Kinetic energy
- C. Thermal energy
- D. Chemical energy
Correct answer: b
Rationale: Kinetic energy is the energy possessed by an object in motion.
6. One staff suggests that they review the pattern of nursing care that they are using, which is
- A. job description
- B. system used to deliver care
- C. manual of procedure
- D. rules to be followed
Correct answer: B
Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
