1. The largest lymphatic vessel in the body is responsible for draining lymph from most of the body. What is it called?

A. Jugular vein
B. Thoracic duct
C. Subclavian vein
D. Aorta

Correct answer: B

Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body and is responsible for draining lymph from most of the body. It collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities. The jugular vein (A) is a major blood vessel that drains blood from the head. The subclavian vein (C) is responsible for draining blood from the upper extremities. The aorta (D) is the main artery that carries oxygenated blood away from the heart. Therefore, the thoracic duct is the correct answer for the largest lymphatic vessel in the body.

2. An IV bag contains 500ml of saline solution and needs to be infused over 4 hours. What is the flow rate in drops per minute, assuming 20 drops per milliliter?

A. 12.5 drops/min
B. 25 drops/min
C. 50 drops/min
D. 100 drops/min

Correct answer: C

Rationale: Calculate the total volume in drops (500ml * 20 drops/ml = 10,000 drops). Divide this by the infusion time in minutes (4 hours * 60 minutes/hour = 240 minutes) to get the flow rate.

3. Which force opposes the relative motion between surfaces in contact?

A. Tension force
B. Frictional force
C. Gravitational force
D. Magnetic force

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

4. Which of the following is an example of a chemical change?

A. Dissolving sugar in water
B. Boiling water
C. Rusting iron
D. Crushing ice

Correct answer: C

Rationale: Rusting is a chemical reaction where iron reacts with oxygen and water to form iron oxide (rust).

5. What is the unit of force in the SI system?

A. Newton (N)
B. Kilogram (kg)
C. Meter (m)
D. Second (s)

Correct answer: A

Rationale: Force is measured in Newtons, named after Isaac Newton who formulated the laws of motion.

6. She takes pride in saying that the hospital has a decentralized structure. Which of the

A. Flat organization
B. Participatory approach
C. Shared governance
D. Tall organization

Correct answer: B

Rationale: The correct answer is B: 'Participatory approach.' In a decentralized structure, decision-making authority is dispersed throughout the organization rather than being concentrated at the top. A participatory approach involves employees at all levels having a say in decisions that affect their work, fostering collaboration and empowerment. This contrasts with a tall organization, which has many layers of management and a more centralized decision-making process. While shared governance can involve decentralized decision-making, it specifically refers to a model where nurses and other healthcare professionals have a voice in shaping policies and practices within their organization, which is not necessarily the same as a decentralized structure.
