1. Which of the following factors does NOT affect the rate of dissolution of a solute in a solvent?

• A. Temperature
• B. Pressure
• C. Surface area
• D. Particle size

Correct answer: B

Rationale: Pressure does not affect the rate of dissolution of a solute in a solvent. The factors that do affect the rate of dissolution include temperature, surface area, and particle size. Temperature generally increases the rate of dissolution as it provides more energy for the solute particles to break apart and mix with the solvent. Increasing the surface area of the solute by grinding it into smaller particles or increasing its contact area with the solvent can also speed up dissolution. Similarly, reducing the particle size of the solute can increase the rate of dissolution by providing more surface area for interaction with the solvent.

2. The science of classifying organisms into different groups based on their evolutionary relationships is called:

• A. Taxonomy
• B. Microbiology
• C. Genetics
• D. Epidemiology

Correct answer: A

Rationale: Rationale: Taxonomy is the science of classifying organisms into different groups based on their evolutionary relationships. It involves identifying, naming, and categorizing living organisms according to their similarities and differences. Microbiology (option B) is the study of microorganisms, Genetics (option C) is the study of genes and heredity, and Epidemiology (option D) is the study of the distribution and determinants of health-related states or events in populations.

3. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

• A. Her eyes glistened in the moonlight, with tears.
• B. Tears glistened in her eyes with moonlight.
• C. Her eyes, in the moonlight, glistened with tears.
• D. Tears made her eyes glisten in the moonlight.

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

4. Which factor affects the gravitational potential energy of an object the most?

• A. The mass of the object
• B. The distance from the ground
• C. The gravitational force
• D. The shape of the object

Correct answer: B

Rationale: Gravitational potential energy is directly proportional to the height or distance from the ground. As the object is raised higher, its gravitational potential energy increases. The mass of the object affects the gravitational potential energy, but the distance from the ground has a greater impact on it. The gravitational force and the shape of the object do not directly affect the gravitational potential energy.

5. Which of the following guidelines should be least considered in formulating objectives for

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.

6. Which of the following terms refers to a muscle twitch, a single forceful contraction of a muscle fiber?

• A. Tetanus
• B. Trembling
• C. Fasciculation
• D. Rigidity

Correct answer: C

Rationale: The correct answer is C: "Fasciculation." A muscle twitch refers to the involuntary contraction of a small group of muscle fibers. Tetanus (choice A) is a sustained contraction of a muscle caused by rapid stimulation. Trembling (choice B) is the shaking or quivering of muscles. Rigidity (choice D) refers to stiffness or inflexibility in muscles. Fasciculation is the term that specifically describes a muscle twitch, which is a single forceful contraction of a muscle fiber. Therefore, choice C is the most appropriate term for this scenario.
