1. Stephanie delegates effectively if she has authority to act, which is BEST defined as:

• A. having responsibility to direct others
• B. being accountable to the organization
• C. having legitimate right to act
• D. telling others what to do

Correct answer: A

Rationale: The correct answer is A: 'having responsibility to direct others.' Effective delegation involves entrusting tasks and responsibilities to others while still maintaining ultimate accountability. Authority to act means having the responsibility to direct others, making decisions, and overseeing the completion of tasks. This definition aligns with the core concept of delegation, where individuals are empowered and authorized to carry out specific duties. Being accountable to the organization (option B) is important but does not fully capture the proactive nature of delegation. Having a legitimate right to act (option C) is essential for effective delegation, but it is more about the formal authorization rather than the active responsibility to direct others. Simply telling others what to do (option D) is a narrow and authoritarian view of delegation that does not encompass the collaborative and empowering nature of effective delegation.

2. Which hormone, produced by the pancreas, is involved in the regulation of blood sugar levels by inhibiting the release of insulin and promoting the release of glucose into the bloodstream?

• A. Insulin
• B. Glucagon
• C. Cortisol
• D. Somatostatin

Correct answer: D

Rationale: The correct answer is D: Somatostatin. Somatostatin is a hormone produced by the pancreas that plays a key role in regulating blood sugar levels. It inhibits the secretion of insulin, which helps prevent a further decrease in blood sugar levels. Additionally, somatostatin promotes the release of glucose into the bloodstream by inhibiting the release of other hormones that would lower blood sugar levels. This dual action of somatostatin helps maintain blood sugar within a normal range. While insulin is involved in lowering blood sugar levels by promoting glucose uptake, glucagon stimulates the release of glucose from storage to increase blood sugar levels. Cortisol is a steroid hormone produced by the adrenal glands that plays a role in stress response and metabolism, but it is not directly involved in regulating blood sugar levels.

3. What property of a substance refers to its ability to be drawn into thin wires without breaking?

• A. Malleability

4. What is the name of the curved bone in the back that provides support and attachment for muscles?

• A. Sternum
• B. Scapula
• C. Clavicle
• D. Vertebral column

Correct answer: D

Rationale: The correct answer is D: Vertebral column. The vertebral column, also known as the spine or backbone, is a series of small bones called vertebrae that provide support and protection for the spinal cord. It also serves as an attachment point for various muscles in the back. The sternum, scapula, and clavicle are all bones in the upper body, but they do not specifically provide support and attachment for muscles in the back like the vertebral column does.
