1. Which of the following is the correct definition of 'chain of command'?

A. The hierarchy of authority and responsibility
B. Relationship without authority
C. Activity directed through linear authority
D. The tendency for people to perform as expected

Correct answer: A

Rationale: The correct definition of 'chain of command' is the hierarchy of authority and responsibility. This term refers to the order in which authority and power in an organization are wielded and delegated from top management to every employee at every level. Choice B, 'Relationship without authority,' is incorrect because the chain of command specifically involves authority and responsibility. Choice C, 'Activity directed through linear authority,' is not a precise definition of the chain of command, as it does not encompass the full scope of authority and hierarchy. Choice D, 'The tendency for people to perform as expected,' is unrelated to the concept of the chain of command.

2. Which of the following are NOT outcomes of a job analysis? (EXCEPT)

A. Job specification
B. Job evaluation
C. Job description
D. Job performance

Correct answer: C

Rationale: The correct answer is C. Job description is actually one of the key outcomes of a job analysis. A job description details the duties, responsibilities, and requirements of a specific job role. Job specification, job evaluation, and job performance are not outcomes of a job analysis. Job specification refers to the specific qualifications and skills required for a job, job evaluation involves determining the relative worth of different jobs within an organization, and job performance relates to how well an employee is executing their job duties.

3. What is the primary responsibility of a nurse manager in a healthcare setting?

A. To provide direct patient care
B. To manage healthcare facilities
C. To oversee administrative tasks
D. To conduct clinical research

Correct answer: C

Rationale: The correct answer is C: 'To oversee administrative tasks.' Nurse managers in healthcare settings are primarily responsible for managing the administrative aspects of a unit, ensuring smooth operations and efficiency. Choice A is incorrect because providing direct patient care is usually the responsibility of staff nurses, not nurse managers. Choice B is incorrect as managing healthcare facilities involves a broader scope of responsibilities beyond the role of a nurse manager. Choice D is also incorrect as conducting clinical research is typically not a primary responsibility of a nurse manager in a healthcare setting.

4. Which of the following is an example of a secondary prevention strategy?

A. Administering flu vaccinations
B. Screening for hypertension
C. Performing a mastectomy
D. Providing rehabilitation after surgery

Correct answer: B

Rationale: Screening for hypertension is indeed an example of a secondary prevention strategy. Secondary prevention aims to detect and treat a disease in its early stages to prevent complications. Administering flu vaccinations (Choice A) is an example of primary prevention, aimed at preventing the disease from occurring. Performing a mastectomy (Choice C) is a treatment for an existing condition and not a preventive strategy. Providing rehabilitation after surgery (Choice D) is a form of tertiary prevention that focuses on restoring function and improving quality of life after an illness or injury.

5. A staff nurse describes the unit manager as 'a born leader.' The nurse ascribes to which theory of leadership?

A. Trait theories
B. Behavioral theories
C. Formal leadership theories
D. Democratic leadership theories

Correct answer: A

Rationale: The correct answer is A: Trait theories. The nurse describing the unit manager as 'a born leader' aligns with trait theories of leadership, which suggest that certain inborn characteristics or traits contribute to effective leadership. This theory emphasizes that leaders possess natural qualities that make them suitable for leadership roles. Choices B, C, and D are incorrect. Behavioral theories focus on the actions and behaviors of leaders, formal leadership theories emphasize organizational structure and roles, and democratic leadership theories pertain to a style of leadership that involves participative decision-making.
