Nursing Leadership and Management

1. She came across a theory which states that the leadership style is effective dependent on the

Correct answer: A

Rationale: The correct answer is A: "Democratic" because democratic leadership style is effective dependent on the participation and input of team members. In a democratic leadership style, decisions are made through discussion and consensus building, which can lead to higher levels of job satisfaction and productivity. Authoritarian leadership style emphasizes control and obedience, while laissez-faire leadership style lacks guidance and structure, and bureaucratic leadership style focuses on rules and regulations. Therefore, democratic leadership style is considered effective as it values the opinions and contributions of team members, leading to better outcomes and team cohesion.

2. What are energy levels and orbitals?

Correct answer: A

Rationale: Energy levels refer to the specific energies that electrons in an atom can have, while orbitals are the regions within an atom where electrons are most likely to be found. Electrons do not travel in fixed paths around the nucleus like planets around the sun, as suggested in option B. Option C is incorrect because energy levels and orbitals are distinct concepts in atomic structure. Option D is incorrect as energy levels and orbitals are fundamental concepts in understanding the behavior of electrons in atoms.

3. Electrons occupy specific energy levels around the nucleus, but not in fixed orbits. This concept is captured by the:

Correct answer: B

Rationale: Quantum mechanical model. Unlike the Bohr model with its defined electron paths, the quantum mechanical model uses probability distributions to describe electron locations within energy levels.

4. What is the main function of peroxisomes in the cell?

Correct answer: A

Rationale: Rationale: Peroxisomes are membrane-bound organelles found in eukaryotic cells that contain enzymes involved in various metabolic processes. One of the main functions of peroxisomes is to break down hydrogen peroxide, a toxic byproduct of metabolism, into water and oxygen through the action of the enzyme catalase. This process helps protect the cell from oxidative damage caused by hydrogen peroxide. While peroxisomes are involved in other metabolic functions such as lipid metabolism and the synthesis of bile acids, their primary role is the breakdown of hydrogen peroxide.

5. What is a potential limitation of using case studies in scientific research?

Correct answer: C

Rationale: While case studies provide valuable individual details, their small sample size and specific context limit their ability to represent broader trends or populations.

6. Which of the following is an example of a decomposition reaction?

Correct answer: b

Rationale: Decomposition reactions involve the breakdown of a compound into simpler substances.
