Nursing Leadership and Management

1. She tries to design an organizational structure that allows communication to flow in all

Correct answer: A

Rationale: The correct answer is 'A: Centralized.' In a centralized organizational structure, decision-making authority and communication flow through a single point of control or a specific group of individuals. This setup ensures that communication channels are streamlined and information is disseminated efficiently. By designing an organizational structure that allows communication to flow in all directions, it suggests a decentralized structure where decision-making authority is distributed across various levels and departments. Therefore, 'Centralized' is the best fit for the scenario described in the question.

2. Which hormone is responsible for stimulating the development of sex organs and secondary sex characteristics during puberty?

Correct answer: B

Rationale: The correct answer is B: Testosterone (in males) and Estrogen (in females). During puberty, the release of these sex hormones plays a crucial role in the development of sex organs and secondary sex characteristics. Testosterone is responsible for male characteristics like facial hair, deepening of the voice, and muscle growth, while Estrogen contributes to female features such as breast development and the widening of hips. Growth hormone primarily regulates overall growth and development, while Insulin is involved in glucose metabolism and Thyroid hormone controls metabolism and energy levels. Therefore, the correct choice is B as Testosterone and Estrogen are specifically responsible for the changes seen during puberty.

3. In the female reproductive system, what structure produces eggs (ova)?

Correct answer: A

Rationale: The correct answer is B: Ovaries. The ovaries are the primary reproductive organs in the female body responsible for producing eggs (ova) through a process called ovulation. The fallopian tubes serve as the passageway for the egg to travel from the ovary to the uterus for potential fertilization. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The vagina is the muscular canal that connects the uterus to the outside of the body and serves as the birth canal during childbirth. Therefore, the ovaries are specifically responsible for the production of eggs in the female reproductive system.

4. Homologous structures are similar structures in different organisms that have a common evolutionary origin. An example is:

Correct answer: B

Rationale: Rationale: Homologous structures are similar structures found in different organisms that share a common evolutionary origin. In this case, the arm of a human, the wing of a bat, and the flipper of a whale are all examples of homologous structures. Despite serving different functions in these organisms, they share a common underlying structure due to their evolutionary relationship. These structures are evidence of a shared ancestry and are modified over time to suit the specific needs of each species. Option A (Butterfly wings and bird wings) refers to analogous structures, which have similar functions but different evolutionary origins. Option C (The eyes of an octopus and a human) describes convergent evolution, where similar traits evolve independently in different species due to similar environmental pressures. Option D (The stinger of a bee and the barb of a cactus) refers to unrelated

5. A car is traveling on a curved road. What force keeps the car moving along the curved path?

Correct answer: D

Rationale: In this case, static friction acts between the tires and the road, providing the centripetal force required to keep the car moving in a circle even though it's traveling in a straight line relative to the ground.

6. What is the name for the change in enthalpy (heat) associated with a chemical reaction at constant pressure?

Correct answer: D

Rationale: The correct answer is D, Heat of reaction. The heat of reaction, also known as the enthalpy change, is the amount of heat absorbed or released during a chemical reaction at constant pressure. Entropy (A) is a measure of the disorder or randomness of a system. Enthalpy (B) is the total heat content of a system. Gibbs free energy (C) is a measure of the energy available to do work in a system at constant temperature and pressure.
