• A. The cats meows filled the room.
• B. I visited my friends' house.
• C. She borrowed Johns book.
• D. The childrens toys were scattered everywhere.

2. What property of a substance remains constant regardless of the amount of the substance present?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

3. 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.

4. Ms. Valencia is responsible to the number of personnel reporting to her. This principle refers

• A. Span of control
• B. Unity of command
• C. Carrot and stick principle
• D. Esprit d’ corp

Correct answer: B

Rationale: The correct answer is B: Unity of command. Unity of command is a fundamental principle of management stating that each employee should receive orders from only one supervisor to avoid confusion and ensure clarity in the chain of command. In this scenario, Ms. Valencia's responsibility for the number of personnel reporting to her aligns with the concept of unity of command. Span of control refers to the number of subordinates a supervisor can efficiently manage, while the carrot and stick principle involves motivating employees through rewards and punishments. Esprit d’ corp refers to the sense of unity and camaraderie within a group.

5. What happens to the concentration of hydrogen ions (\([H^+]\)) in a solution as the pH increases?

• A. Increases
• B. Decreases
• C. Remains constant
• D. Becomes neutral

Correct answer: B

6. Action potentials, the all-or-nothing electrical signals traveling along neurons, are generated by the movement of:

• A. Glucose
• B. Sodium and potassium ions
• C. Neurotransmitters
• D. Myelin

Correct answer: B

Rationale: The correct answer is B: Sodium and potassium ions. Action potentials are generated by the movement of sodium and potassium ions across the neuronal membrane. During depolarization, sodium ions rush into the cell, causing a change in electrical charge. This influx of positive ions triggers the opening of voltage-gated potassium channels, allowing potassium ions to exit the cell during repolarization. Glucose is a source of energy for cells but does not directly generate action potentials. Neurotransmitters are chemical messengers released at synapses, while myelin is a fatty substance that insulates axons, speeding up the conduction of action potentials but not directly generating them.
