Chemistry
1. The process of a gas changing into a liquid is called:
- A. Evaporation
- B. Boiling
- C. Condensation
- D. Sublimation
Correct answer: C
Rationale: Condensation happens when gas particles lose energy and slow down, transitioning into the liquid state.
2. What is the lysosome?
- A. A sac-like structure that contains enzymes that break down cellular components
- B. A network of tubules that transport proteins and lipids throughout the cell
- C. The site of protein synthesis
- D. The site of cellular respiration
Correct answer: A
Rationale: Rationale: Lysosomes are membrane-bound organelles found in animal cells that contain digestive enzymes. These enzymes help break down various cellular components, such as proteins, lipids, carbohydrates, and even foreign particles like bacteria. This process of breaking down and recycling cellular components is essential for maintaining cell health and function. Options B, C, and D do not accurately describe the function or structure of a lysosome.
3. 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.
4. Which of the following is the best guarantee that the patient’s priority needs are met?
- A. Checking with the relative of the patient
- B. Preparing a nursing care plan in collaboration with the patient
- C. Consulting with the physician
- D. Coordinating with other members of the team
Correct answer: B
Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.
5. Which of the following terms refers to a muscle that lengthens while another muscle contracts to produce movement?
- A. Synergist
- B. Agonist
- C. Antagonist
- D. Flexor
Correct answer: C
Rationale: The correct answer is C: Antagonist. In muscle physiology, an antagonist refers to a muscle that lengthens while another muscle contracts to produce movement. This relationship allows for smooth and coordinated movement by controlling the action of the agonist muscle. For example, when you bend your arm, the biceps muscle (agonist) contracts to flex the arm while the triceps muscle (antagonist) lengthens to allow for this movement. Synergists assist the agonist muscle in performing a movement, while flexors are a type of muscle that decreases the angle between bones at a joint. Therefore, the antagonist best fits the description of a muscle that lengthens while another muscle contracts.
6. What is the unit of measurement for momentum?
- A. Newton-second (N·s)
- B. Kilogram-meter (kg·m)
- C. Joule (J)
- D. Meter per second (m/s)
Correct answer: A
Rationale: Momentum is defined as the product of an object's mass and its velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s). Therefore, the unit of momentum is kilogram-meter per second (kg·m/s). By Newton's second law of motion (F = ma), force is measured in Newtons (N), which is equivalent to kg·m/s². Therefore, multiplying the unit of force (N) by the unit of time (s) gives the unit of momentum as Newton-second (N·s).
