1. She notes that there is an increasing unrest of the staff due to fatigue brought about by
- A. Evaluate the overall result of the unrest
- B. Initiate a group interaction
- C. Develop a plan and implement it
- D. Identify external and internal forces.
Correct answer: C
Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.
2. What is the main function of transition words and phrases in writing?
- A. To add unnecessary embellishments and fluff.
- B. To emphasize specific words or phrases in the text.
- C. To connect ideas smoothly and guide the reader's flow.
- D. To introduce opposing viewpoints and counterarguments.
Correct answer: C
Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.
3. What is the main purpose of biological classification?
- A. To create a rigid and unchanging system for labeling organisms
- B. To understand the diversity and interconnectedness of life
- C. To simplify nature into neat and tidy categories
- D. To assign organisms to specific ecological niches
Correct answer: B
Rationale: Rationale: Biological classification, also known as taxonomy, is the science of categorizing and organizing living organisms based on shared characteristics. The main purpose of biological classification is not to create a rigid and unchanging system (option A) or to simplify nature into neat and tidy categories (option C). Instead, it aims to help us understand the diversity of life on Earth and how different organisms are related to each other. By classifying organisms into groups based on their evolutionary relationships, we can gain insights into the interconnectedness of life and better appreciate the complexity and beauty of the natural world. Assigning organisms to specific ecological niches (option D) is more related to ecological studies rather than biological classification.
4. . Edema, characterized by swelling due to fluid buildup, can be a sign of:
- A. Heart failure
- B. Liver disease
- C. Lymphatic system dysfunction
- D. All of the above
Correct answer: D
Rationale: Edema, which is the accumulation of fluid in tissues leading to swelling, can be caused by various medical conditions. Heart failure can result in fluid retention due to the heart's inability to pump effectively, leading to edema. Liver disease can cause edema by impairing the liver's ability to produce proteins that help maintain fluid balance. Dysfunction of the lymphatic system can also lead to edema, as the lymphatic vessels play a crucial role in draining excess fluid from tissues. Therefore, all the options (heart failure, liver disease, and lymphatic system dysfunction) can contribute to the development of edema, making 'All of the above' the correct answer.
5. Which part of the heart generates the QRS complex on an ECG?
- A. Sinoatrial node (SA node)
- B. Atrioventricular node (AV node)
- C. Bundle of His
- D. Ventricular muscle cells
Correct answer: D
Rationale: The correct answer is D, ventricular muscle cells. The QRS complex on an ECG represents the depolarization of the ventricles. This electrical activity is generated by the spread of impulses through the bundle branches and Purkinje fibers to the ventricular muscle cells. The SA node (option A) is responsible for initiating the electrical impulse in the heart, but it does not directly generate the QRS complex. The AV node (option B) delays the impulse to allow for proper coordination of atrial and ventricular contractions. The Bundle of His (option C) and its branches facilitate the conduction of the electrical signal from the AV node to the ventricles but do not generate the QRS complex directly.
6. What is the relationship between work and the displacement of an object?
- A. Work depends only on the force applied, not displacement
- B. Work is directly proportional to displacement
- C. Work is inversely proportional to displacement
- D. Work is unrelated to displacement
Correct answer:
Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.
