1. As a manager, she focuses her energy on both the quality of services rendered to the patients

A. Country club management
B. Organization man management
C. Team management
D. Authority-obedience management

Correct answer: B

Rationale: The correct answer is 'B: Organization man management.' This type of management focuses on maintaining the efficiency and structure of an organization. In this scenario, the manager's emphasis on the quality of services aligns with the principles of organization man management, which prioritizes the coordination of tasks and resources to achieve optimal results within the organization. This contrasts with 'Country club management,' which emphasizes employee satisfaction over task accomplishment; 'Team management,' which focuses on collaboration and teamwork; and 'Authority-obedience management,' which centers on strict hierarchical control. Therefore, the most appropriate choice is 'B: Organization man management.'

2. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

A. 0.00025 milliliters
B. 0.0025 milliliters
C. 0.025 milliliters
D. 0.25 milliliters

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

3. Which sentence uses the present perfect continuous tense correctly?

A. I have been working on this project since morning.
B. She has finished the book already.
C. They will be leaving for vacation tomorrow.
D. He had been living in the city for ten years.

Correct answer: A

Rationale: Option A emphasizes the ongoing action (working) that started in the past and continues to the present.

4. Identify the interrogative sentence in the following options:

A. The delicious pie disappeared quickly.
B. What is your favorite color?

5. The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?

A. 34kg
B. 45kg
C. 56kg
D. 68kg

Correct answer: C

Rationale: 56kg: Rearrange the formula to solve for weight: weight = BMI * height^2.

6. The constituents of an atomic nucleus consist of:

A. Electrons and protons only
B. Protons and neutrons only
C. Electrons, protons, and neutrons
D. None of the above

Correct answer: B

Rationale: The correct answer is B: "Protons and neutrons only." This is because the atomic nucleus is composed of protons, which carry a positive charge, and neutrons, which are neutral. Electrons are found outside the nucleus in electron shells. Protons and neutrons are collectively known as nucleons and are responsible for the mass of the atom. Electrons are much lighter and are involved in chemical reactions and bonding. Therefore, the constituents of an atomic nucleus are specifically protons and neutrons, making option B the correct choice.
