Question 1 of 5
Which of the following situations represents work being done on an object?
Correct Answer: C
Rationale: The correct answer is C because lifting a box to place it on a shelf involves exerting a force to overcome gravity, resulting in the displacement of the box. Work is defined as the product of force and displacement in the direction of the force applied. In this scenario, the force applied (lifting the box) results in the box being displaced vertically, which meets the criteria for work being done. Choices A, B, and D do not represent work being done on an object because in these situations, the objects do not experience a displacement in the direction of the force applied. In choice A, the wall does not move, so no displacement occurs. In choice B, carrying a heavy object without lifting it does not involve any vertical displacement. In choice D, holding a book stationary in your hand does not result in any displacement of the book. Therefore, only choice C fulfills the criteria for work being done on an object.
Question 2 of 5
Which of the following is the smallest unit of matter?
Correct Answer: B
Rationale: The correct answer is B: Atom. An atom is the smallest unit of matter that retains the properties of an element. Atoms are made up of protons, neutrons, and electrons. A molecule (A) consists of two or more atoms bonded together. A compound (C) is a substance composed of two or more different elements chemically bonded. An element (D) is a pure substance made up of only one type of atom. Therefore, the smallest unit of matter is the atom.
Question 3 of 5
What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?
Correct Answer: B
Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid. Lymph fluid can accumulate in tissues due to various reasons such as lymphatic system blockages or underlying medical conditions. Anemia (A) is a condition characterized by a deficiency of red blood cells or hemoglobin. Hypertension (C) is high blood pressure, not related to lymph fluid buildup. Diabetes (D) is a metabolic disorder affecting blood sugar levels, not directly related to lymph fluid accumulation. In this case, edema is the most appropriate choice as it specifically addresses the swelling caused by lymph fluid buildup.
Question 4 of 5
What is the maximum volume of air that the lungs can hold after a full forced inhalation?
Correct Answer: C
Rationale: The correct answer is C: Total lung capacity. Total lung capacity is the maximum volume of air the lungs can hold after a full forced inhalation. It includes all the volumes within the lungs, such as tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. It is the sum of vital capacity and residual volume. Inspiratory capacity (A) is the maximum volume of air that can be inhaled after a normal exhalation. Tidal volume (B) is the volume of air inspired or expired during normal breathing. Vital capacity (D) is the maximum volume of air that can be exhaled after a maximum inhalation, not the total volume the lungs can hold.
Question 5 of 5
Which of the following vessels is responsible for pumping oxygenated blood to the body?
Correct Answer: D
Rationale: The correct answer is D: Aorta. The aorta is responsible for pumping oxygenated blood to the body. This happens after the oxygenated blood leaves the left ventricle of the heart through the aortic valve. The aorta is the largest artery in the body and carries blood to all parts of the body, supplying oxygen and nutrients. The other choices are incorrect because: A: Right ventricle pumps deoxygenated blood to the lungs. B: Left ventricle pumps oxygenated blood to the body. C: Pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.
