1. A medication dosage is listed as 1/4 gram. What is the equivalent dosage in milligrams (1 gram = 1000 milligrams)?

• A. 125mg
• B. 250mg
• C. 375mg
• D. 500mg

Correct answer: D

Rationale: Multiply the gram dosage (1/4) by the conversion factor (1000mg/gram) to get 250 milligrams.

2. What is the difference between emphysema and chronic bronchitis, both chronic obstructive pulmonary diseases (COPD)?

• A. Emphysema damages alveoli, while chronic bronchitis inflames airways.
• B. Emphysema causes coughing, while chronic bronchitis leads to shortness of breath.
• C. Emphysema is more reversible than chronic bronchitis.
• D. Emphysema affects only smokers, while chronic bronchitis can occur in non-smokers.

Correct answer: A

Rationale: The correct answer is A. Emphysema and chronic bronchitis are both types of COPD, but they have distinct characteristics. Emphysema is characterized by the destruction of the alveoli in the lungs, which impairs the exchange of oxygen and carbon dioxide. This damage to the alveoli leads to difficulty breathing and decreased lung function. On the other hand, chronic bronchitis involves inflammation and narrowing of the airways, leading to excessive mucus production and a persistent cough. While both conditions are chronic and progressive, emphysema primarily affects the alveoli, while chronic bronchitis primarily affects the airways. Understanding these differences is crucial for appropriate diagnosis and management of COPD.

3. Express 0.75 as a fraction.

• A. 4/5
• B. 3/4
• C. 1/2
• D. 1/4

Correct answer: B

Rationale: Decimals can be represented as fractions where the denominator is a power of 10 (in this case, 10 raised to the power of -1, or 1/10th). So, 0.75 is equivalent to 7/10. We can simplify this fraction by dividing the numerator and denominator by 5, resulting in 3/4.

4. A substance that can donate a hydroxide ion (OH-) in solution is classified as a:

• A. Salt
• B. Base
• C. Neutral compound
• D. Dehydrating agent

Correct answer: B

Rationale: Bases accept protons (H+) and can donate hydroxide ions

5. Bradycardia refers to a heart rate that is:

• A. Normal (60-100 bpm)
• B. Slightly elevated (100-120 bpm)
• C. Significantly elevated (>120 bpm)
• D. Abnormally slow (<60 bpm)

Correct answer: D

Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.

6. He emphasizes to the team that they need to put their efforts together towards the attainment

• A. Span of control
• B. Unity of direction
• C. Unity of command
• D. Command responsibility

Correct answer: B

Rationale: The correct answer is B: Unity of direction. Unity of direction is a principle of management which states that all activities within an organization should be directed towards the same objectives. In this scenario, the leader is stressing the importance of aligning the team's efforts towards a common goal or objective. This ensures that everyone is working towards a shared purpose, avoiding conflicting or contradictory actions. Span of control refers to the number of subordinates a manager can effectively supervise. Unity of command relates to the principle that employees should receive orders from only one supervisor to avoid confusion and conflict. Command responsibility is a term often used in the context of accountability for actions taken under one's command. Therefore, the most appropriate concept in this context is Unity of direction.
