Nursing Elites

1. Julius orients his staff on the patterns of reporting relationship throughout the organization.

• A. Span of control
• B. Hierarchy
• C. Esprit d’ corps
• D. Unity of direction

Correct answer: B

Rationale: The correct answer is B: Hierarchy. Hierarchy refers to the structure of authority and responsibility within an organization, including the levels of management and the reporting relationships. In this scenario, Julius is orienting his staff on the patterns of reporting relationships, which is a key aspect of hierarchy. Span of control refers to the number of employees a manager can effectively supervise, esprit de corps pertains to team spirit and unity among employees, and unity of direction relates to ensuring all activities are focused on the same objectives. Therefore, the most appropriate term for Julius's action is hierarchy.

2. 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

Rationale: As the pH increases, the concentration of hydrogen ions decreases. The relationship is inversely proportional

3. 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.

4. Which muscular pouch in the upper left abdomen stores food after swallowing and begins mechanical and chemical digestion?

• A. Esophagus
• B. Stomach
• C. Small intestine
• D. Large intestine

Correct answer: B

Rationale: The correct answer is B: Stomach. The stomach is the muscular pouch in the upper left abdomen that stores food after swallowing. It is responsible for beginning both mechanical and chemical digestion processes. Once food enters the stomach, it is mixed with gastric juices and enzymes that break down the food into smaller particles. The stomach also contracts and relaxes to further mix the food with digestive juices. The esophagus is a tube that connects the throat to the stomach and does not store food or participate in digestion. The small intestine and large intestine are parts of the digestive system, but they are not muscular pouches in the upper left abdomen responsible for storing and digesting food.

5. The phrase "green alternative" suggests that bioremediation is...

• A. The most economical option for plastic cleanup.
• B. Faster and more efficient than traditional methods.
• C. Environmentally friendly and less harmful than other solutions.
• D. More aesthetically pleasing than existing approaches.

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.

6. When a car brakes to a stop, friction between the tires and the road acts as:

• A. A balanced force
• B. An unbalanced force causing acceleration
• C. An unbalanced force causing the car to remain at rest
• D. No force at all

Correct answer: B

Rationale: Friction opposes the car's motion, acting as an unbalanced force that decelerates the car and brings it to a stop.
