1. When Harry uses team nursing as a care delivery system, he and his team need to assess the

A. Each patient as listed on the worksheet
B. Patients who needs least care
C. Medications and treatments required for all patients
D. Patients who need the most care

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.

2. What is the acceleration of an object moving at a constant speed of 20 m/s if it comes to a complete stop within 5 seconds?

A. 0 m/s² (no acceleration)
B. 4 m/s²
C. -4 m/s²
D. Information insufficient

Correct answer: C

Rationale: The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (as the object comes to a complete stop), the initial velocity is 20 m/s, and the time taken is 5 seconds. Plugging these values into the formula, we get acceleration = (0 m/s - 20 m/s) / 5 s = -20 m/s / 5 s = -4 m/s². Therefore, the acceleration is -4 m/s².

3. What is the name for the tiny particles that make up atoms?

A. Protons
B. Electrons
C. Neutrons
D. Subatomic particles

Correct answer: D

Rationale: Protons, neutrons, and electrons are all subatomic particles that make up atoms.

4. What transport mechanism uses vesicles to move materials within the cell?

A. Endocytosis
B. Active transport
C. Diffusion
D. Exocytosis

Correct answer: A

Rationale: The correct answer is A: Endocytosis. Endocytosis is a transport mechanism in which cells take in molecules or particles by engulfing them in a vesicle. This process allows materials to be transported within the cell. Active transport (option B) requires energy to move molecules across the cell membrane against their concentration gradient. Diffusion (option C) is the movement of molecules from an area of high concentration to an area of low concentration. Exocytosis (option D) is the process by which cells release substances from vesicles into the extracellular environment. Therefore, endocytosis is the transport mechanism that uses vesicles to move materials within the cell.

5. A solution is considered saturated when...

A. More solute can be dissolved
B. The solvent starts to evaporate
C. The solution becomes cloudy
D. It reaches a specific temperature

Correct answer: B

Rationale: The correct answer is B: 'The solvent starts to evaporate.' A solution is considered saturated when the solvent can no longer dissolve any more solute at a given temperature. When the solvent starts to evaporate, it means that the solution is becoming more concentrated and reaching its saturation point. This is a key indicator of a saturated solution. The other options do not accurately describe the concept of a saturated solution, making them incorrect choices.

6. Adipose tissue, also known as fat, serves multiple functions. Which of these is NOT a function of adipose tissue?

A. Insulation
B. Energy storage
C. Hormone production
D. Muscle movement

Correct answer: D

Rationale: Adipose tissue plays various essential roles in the body, including insulation to help regulate body temperature, energy storage by storing excess energy in the form of fat, and hormone production such as leptin and adiponectin. However, adipose tissue is not directly responsible for muscle movement. Muscles are primarily responsible for movement, while adipose tissue provides cushioning and support around organs. Therefore, option D, 'Muscle movement,' is the correct answer as it does not align with the functions of adipose tissue.
