1. The muscular tube that carries urine from the kidneys to the bladder is called the:

• A. Nephron
• B. Ureter
• C. Urethra
• D. Glomerulus

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.

2. In the context of the cardiac cycle, the P wave on an electrocardiogram (ECG) represents:

• A. Atrial depolarization
• B. Ventricular depolarization
• C. Atrial repolarization
• D. Ventricular repolarization

Correct answer: A

Rationale: The correct answer is A: "Atrial depolarization." The P wave on an ECG represents the depolarization of the atria, specifically the spread of electrical activity through the atria causing them to contract and push blood into the ventricles. This is the first wave observed on the ECG and signifies the beginning of the cardiac cycle. Ventricular depolarization is represented by the QRS complex, atrial repolarization is typically not visible on a standard ECG due to its timing with the QRS complex, and ventricular repolarization is represented by the T wave. Therefore, option A is the most appropriate choice in this context.

3. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

• A. Staffing
• B. Scheduling
• C. Recruitment
• D. Induction

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.

4. Which word completes the sentence "He was ____ by the unexpected turn of events."

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: "Bewildered" best describes the confusion caused by the unexpected events.

5. Photons, the basic unit of light, are:

• A. Charged particles
• B. Packets of energy with wave-particle duality
• C. Electromagnetic waves only
• D. Always absorbed by matter

Correct answer: B

Rationale: The correct answer is B: Packets of energy with wave-particle duality. Photons are the smallest discrete amount of electromagnetic radiation and exhibit both wave-like and particle-like properties. While photons do not have a charge, they do carry energy and momentum. This dual nature of photons is a fundamental concept in quantum mechanics. Photons can travel as both waves and particles, and their behavior is described by the wave-particle duality principle. Therefore, option B accurately describes the nature of photons as packets of energy with wave-particle duality.

6. 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.
