1. 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.

2. Which of the following is a unit of power?

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

Correct answer: c

Rationale: Watt is the unit of power, measuring the rate of work done or energy transfer.

3. Which type of waves do not require a medium for propagation?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: c

Rationale: Electromagnetic waves (such as light or radio waves) can travel through a vacuum as they do not require a medium.

4. He asserts the importance of promoting a positive organizational culture in their unit. Which

• A. Proactive and caring with one another
• B. Competitive and perfectionist
• C. Powerful and oppositional
• D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

5. Differentiate between gene therapy and genetic engineering in the context of human intervention.

• A. Gene therapy aims to modify existing genes within body cells, while genetic engineering manipulates genes in embryos to be passed on to offspring.
• B. Gene therapy focuses on treating genetic diseases, while genetic engineering enhances desirable traits or eliminates undesirable ones.
• C. Both involve directly altering the DNA sequence, but gene therapy targets somatic cells and genetic engineering modifies germline cells.
• D. There is no fundamental difference; both terms are synonymous.

Correct answer: B

Rationale: Rationale: A) Incorrect. Gene therapy does aim to modify existing genes within body cells, but genetic engineering does not necessarily manipulate genes in embryos to be passed on to offspring. Genetic engineering can involve modifying genes in any type of cell, not just embryos. B) Correct. Gene therapy is a medical intervention that aims to treat genetic diseases by correcting or replacing faulty genes within an individual's body cells. On the other hand, genetic engineering involves modifying genes to enhance specific traits or eliminate undesirable ones, often in the context of agriculture or biotechnology. C) Incorrect. While both gene therapy and genetic engineering involve altering DNA sequences, the distinction lies in the target cells. Gene therapy targets somatic cells (non-reproductive cells), while genetic engineering typically involves modifying germline cells (reproductive cells that can pass on genetic changes to offspring). D) Incorrect. There is

6. A medication order is written as 3/4 of a tablet. If each tablet is 500mg, what is the equivalent dosage in milligrams?

• A. 375mg
• B. 425mg
• C. 450mg
• D. 475mg

Correct answer: A

Rationale: Multiply the tablet strength (500mg) by the fractional dose (3/4) to get 375 milligrams.
