4. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

• A. Focuses on management tasks
• B. Is a caretaker
• C. Uses trade-offs to meet goals
• D. Inspires others with vision

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

6. The following are basic steps in the controlling process of the department. Which of the

• A. Measure actual performance
• B. Set nursing standards and criteria
• C. Compare results of performance to standards and objectives
• D. Identify possible courses of action

Correct answer: A

Rationale: The correct answer is A: 'Measure actual performance.' In the controlling process of a department, measuring actual performance is a crucial step to assess how well the department is performing compared to set standards and objectives. By measuring actual performance, managers can identify any deviations from the established criteria and take necessary corrective actions. Setting nursing standards and criteria (option B) is typically done before the controlling process begins, to provide a benchmark for measuring performance. Comparing results of performance to standards and objectives (option C) is done after measuring actual performance. Identifying possible courses of action (option D) is part of the corrective action phase that follows measuring actual performance. Therefore, option A is the most appropriate step in the controlling process of a department.
