Nursing Elites

1. A garden bed has a side length of 8 meters. What is its perimeter?

• A. 16m
• B. 24m
• C. 32m
• D. 64m

Correct answer: C

Rationale: : Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.

2. What is the periodic law?

• A. The statement that the properties of the elements are a periodic function of their atomic numbers.
• B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
• C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
• D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

3. Which of the following is a strong base commonly used in cleaning products?

• A. Sodium hydroxide (NaOH)
• B. Ammonium hydroxide (NHâ‚„OH)
• C. Calcium hydroxide (Ca(OH)â‚‚)
• D. Potassium hydroxide (KOH)

Correct answer: A

Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.

4. She checks the documentary requirements for the applicants for staff nurse position. Which

• A. Certificate of previous employment
• B. Record of related learning experience (RLE)
• C. Membership to accredited professional organization

When hiring staff nurses, verifying their membership to an accredited professional organization is crucial as it ensures that the applicant is recognized and affiliated with a reputable body in the nursing field. This membership signifies adherence to professional standards and ongoing education and development.

5. Biodiversity is important for healthy ecosystems because it:

• A. Increases competition for resources
• B. Provides stability and resilience to disturbances
• C. Slows down nutrient cycling
• D. Reduces the number of decomposers

Correct answer: B

Rationale: Rationale: Biodiversity refers to the variety of living organisms in a particular area. A diverse ecosystem is better able to withstand and recover from disturbances such as natural disasters, climate change, or human impacts. This is because different species play unique roles in the ecosystem, and a higher level of biodiversity means there are more species available to fulfill these roles. For example, if one species is negatively affected by a disturbance, other species may be able to compensate for its loss, maintaining the overall functioning of the ecosystem. Therefore, biodiversity provides stability and resilience to disturbances, making ecosystems healthier and more sustainable.

6. What property of matter measures the amount of space occupied by an object?

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