1. What is the unit of measurement for power?

• A. Joule (J)
• B. Newton (N)
• C. Watt (W)
• D. Kilogram-meter (kg·m)

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

2. She wants to ensure that every task is carried out as planned. Which of the following tasks is

• A. Instructing the members of the standards committee to prepare policies
• B. Reviewing the existing policies of the hospital
• C. Evaluating the credentials of all nursing staff
• D. Checking if activities conform to schedule

Correct answer: C

Rationale: The correct answer is C because evaluating the credentials of all nursing staff is essential to ensuring that the right individuals are in place to carry out tasks effectively. This task directly contributes to maintaining a high standard of performance and ensuring that the team is qualified for their roles. In contrast, the other options focus on policies, reviews, and schedules, which are important but do not directly address the qualifications and capabilities of the staff responsible for task execution.

3. Certain medications can suppress the immune system to treat autoimmune diseases or prevent organ rejection after transplants. What is a potential risk associated with immunosuppressive drugs?

• A. Increased risk of developing allergies
• B. Increased susceptibility to infections
• C. Both a and b
• D. Neither a nor b

Correct answer: C

Rationale: The correct answer is C: 'Both a and b.' Immunocompromised individuals, who take immunosuppressive drugs, are at an increased risk of developing allergies due to the altered immune response. Additionally, these drugs suppress the immune system's ability to fight off infections, making individuals more susceptible to various pathogens. Therefore, both increased risk of developing allergies and increased susceptibility to infections are potential risks associated with immunosuppressive drugs, making option C the correct choice.

4. What is the acceleration due to gravity near the Earth's surface?

• A. 9.8 meters per second squared (m/s²)
• B. 6.3 meters per second squared (m/s²)
• C. 5.0 meters per second squared (m/s²)
• D. 12.5 meters per second squared (m/s²)

Correct answer: a

Rationale: The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s²

5. Which of the following guidelines should be least considered in formulating objectives for

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.

6. What is the name for the change in enthalpy (heat) associated with a chemical reaction at constant pressure?

• A. Entropy
• B. Enthalpy
• C. Gibbs free energy
• D. Heat of reaction

Correct answer: D

Rationale: The correct answer is D, Heat of reaction. The heat of reaction, also known as the enthalpy change, is the amount of heat absorbed or released during a chemical reaction at constant pressure. Entropy (A) is a measure of the disorder or randomness of a system. Enthalpy (B) is the total heat content of a system. Gibbs free energy (C) is a measure of the energy available to do work in a system at constant temperature and pressure.
