TEAS Test 7 science quizlet
1. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?
- A. Dehydration
- B. Kidney failure
- C. Incontinence
- D. Nephritis
Correct answer: B
Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.
2. What is the condition called when someone experiences a temporary loss of consciousness due to a lack of blood flow to the brain?
- A. Stroke
- B. Epilepsy
- C. Syncope (fainting)
- D. Multiple sclerosis
Correct answer: C
Rationale: Syncope, also known as fainting, is a temporary loss of consciousness caused by a lack of blood flow to the brain. This can occur due to various reasons such as low blood pressure, dehydration, or sudden emotional stress. Strokes involve a disruption of blood flow to the brain resulting in brain cell damage. Epilepsy is a neurological disorder characterized by recurrent seizures. Multiple sclerosis is a chronic autoimmune disease that affects the central nervous system. In this case, the correct answer is 'Syncope' as it directly relates to the temporary loss of consciousness due to decreased blood flow to the brain, distinguishing it from the other options which involve different conditions affecting the nervous system.
3. What principle explains the relationship between pressure, volume, and temperature for ideal gases?
- A. Law of conservation of energy
- B. Newton's laws of motion
- C. Ideal gas law
- D. Archimedes' principle
Correct answer: C
Rationale: The correct answer is the Ideal Gas Law (Choice C). The ideal gas law, PV = nRT, describes the relationship between pressure (P), volume (V), temperature (T), and the number of moles of gas (n) for an ideal gas. It states that the product of pressure and volume is directly proportional to the absolute temperature of the gas when the number of moles is held constant. This law is a fundamental principle in understanding the behavior of ideal gases. Choices A, B, and D are incorrect. The Law of conservation of energy (Choice A) pertains to the principle that energy cannot be created or destroyed; Newton's laws of motion (Choice B) describe the relationship between the motion of an object and the forces acting on it; Archimedes' principle (Choice D) deals with the buoyant force exerted on an object immersed in a fluid. These principles are not directly related to the relationship between pressure, volume, and temperature for ideal gases.
4. Which of the following lists of joint types is in the correct order for increasing amounts of permitted motion (least mobile to most mobile)?
- A. Hinge, condyloid, saddle
- B. Saddle, hinge, condyloid
- C. Saddle, condyloid, hinge
- D. Hinge, saddle, condyloid
Correct answer: A
Rationale: The correct order of joint types, from least mobile to most mobile, is hinge, condyloid, saddle. A hinge joint allows movement in one plane (like a door hinge), a condyloid joint allows movement in two planes but not rotation (like the wrist), and a saddle joint allows movement in multiple directions (like the thumb). Choice A, 'Hinge, condyloid, saddle,' is the correct sequence as it accurately represents the order of increasing permitted motion in joints. Choices B, C, and D are incorrect because they do not follow the correct order of joint types from least mobile to most mobile as required by the question.
5. What is the process of breaking down proteins into amino acids called?
- A. Proteolysis
- B. Lipolysis
- C. Carbohydrate catabolism
- D. Nucleic acid catabolism
Correct answer: A
Rationale: Proteolysis is the specific process of breaking down proteins into amino acids. Lipolysis refers to the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production, not proteins. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides, not proteins. Therefore, in the context of breaking down proteins into amino acids, the correct term is proteolysis.
