Nursing Leadership and Management

1. One leadership theory states that “leaders are born and not made,” which refers to which of the

Correct answer: A

Rationale: The correct answer is A: Trait. The statement 'leaders are born and not made' aligns with the Trait theory of leadership, which suggests that certain individuals are born with innate qualities and characteristics that make them effective leaders. This theory focuses on identifying specific traits, such as intelligence, charisma, and self-confidence, that are believed to be inherent in successful leaders. Charismatic leadership (option B) emphasizes the charm and appeal of a leader, Great Man theory (option C) suggests that leaders are born with unique qualities that set them apart, and Situational leadership (option D) focuses on adapting leadership style based on the situation. However, the statement in the question best corresponds to the Trait theory, making option A the correct choice.

2. What is the primary factor that determines whether a solute will dissolve in a solvent?

Correct answer: c

Rationale: The molecular structure of the solute and solvent plays a key role in determining solubility. The other choices may influence solubility but are not the primary determining factor.

3. Which type of carbohydrate is the main component of the cell wall in plant cells?

Correct answer: C

Rationale: The correct answer is C: Cellulose. Cellulose is a structural polysaccharide and the main component of the cell wall in plant cells. Starch, option A, is a storage polysaccharide found in plants, while glucose, option B, is a simple sugar and a basic unit of carbohydrates, not the main component of plant cell walls. Chitin, option D, is a structural polysaccharide found in the exoskeletons of arthropods and fungal cell walls, not in plant cell walls. Understanding the unique composition of plant cell walls helps in differentiating the types of carbohydrates present in various cellular structures.

4. What checkpoint mechanism ensures all chromosomes are attached to the spindle fibers before anaphase begins?

Correct answer: A

Rationale: Rationale: A) Prometaphase is the correct answer because it is the stage of mitosis where all chromosomes are attached to the spindle fibers before anaphase begins. During prometaphase, the nuclear envelope breaks down, allowing the spindle fibers to attach to the kinetochores of the chromosomes. This attachment is necessary for proper chromosome alignment and segregation during anaphase. B) Metaphase is incorrect because it is the stage where chromosomes are aligned at the metaphase plate but do not necessarily have all spindle fibers attached. C) Cyclin degradation is incorrect because it is a regulatory mechanism that controls the progression of the cell cycle but is not specifically related to ensuring all chromosomes are attached to spindle fibers. D) Sister chromatid cohesion is incorrect because it refers to the physical connection between sister chromatids that is maintained until anaphase, but it does not ensure that all chromosomes are attached to spindle fibers.

5. Which of the following is the primary function of the ovaries in the female reproductive system?

Correct answer: C

Rationale: The primary function of the ovaries in the female reproductive system is to produce eggs (ova). Ovaries are responsible for the production and release of eggs during the menstrual cycle, which can be fertilized by sperm to form a zygote. This process is essential for reproduction and the continuation of the species. Options A, B, and D are incorrect as transporting sperm to the uterus is the role of the fallopian tubes, producing milk for feeding offspring is the function of the mammary glands, and regulating urination is controlled by the bladder and associated muscles, not the ovaries.

6. Approximately how many muscles are there in the human body?

Correct answer: D

Rationale: The correct answer is D. There are over 600 muscles in the human body. Muscles are responsible for movement, posture, and generating heat in the body. The exact number of muscles can vary slightly from person to person, but it is generally accepted that there are over 600 muscles in the human body. These muscles work together to allow us to perform various movements and activities throughout our daily lives.
