TEAS Practice Test Science
1. Which part of the heart receives oxygenated blood from the lungs?
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Correct answer: A
Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs, which is then pumped into the left ventricle and out to the rest of the body. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle to be pumped to the lungs for oxygenation. Choices B, C, and D are incorrect as they do not directly receive oxygenated blood from the lungs.
2. Which of the following options contains a possessive pronoun?
- A. If the patient chooses to leave, let them know the right to do so is theirs.
- B. When we support patients in these ways, the hospital's mission is accomplished.
- C. Take personal items to the front desk once you are finished.
- D. This hospital has some problems, no doubt.
Correct answer: A
Rationale: Choice A, 'theirs,' is a possessive pronoun indicating ownership. In this sentence, 'theirs' shows possession by referring to something belonging to the patient. Choices B, C, and D do not contain possessive pronouns. Choice B uses the possessive form 'hospital's,' but it is a possessive noun, not a pronoun. Choice C uses 'personal items,' where 'personal' is an adjective and 'items' is a noun. Choice D does not include any possessive pronouns or possessive nouns.
3. How do vaccines primarily function within the body?
- A. Creating a physical barrier against pathogens
- B. Triggering an inflammatory response
- C. Developing immunological memory to a specific pathogen
- D. Activating phagocytes to engulf pathogens
Correct answer: C
Rationale: Vaccines primarily function by stimulating the immune system to develop immunological memory to a specific pathogen. When a vaccine is administered, it exposes the immune system to a harmless version of a pathogen or a piece of it. This exposure triggers the immune response, leading to the production of antibodies and memory cells specific to that pathogen. Choice A is incorrect because vaccines do not create a physical barrier; rather, they prepare the immune system to recognize and fight specific pathogens. Choice B is incorrect as vaccines do trigger an immune response, but the primary goal is to create memory rather than inflammation. Choice D is incorrect as vaccines do not directly activate phagocytes; instead, they stimulate the immune system to generate a targeted response against a particular pathogen.
4. How many millimeters are in a meter?
- A. 100 mm
- B. 1,000 mm
- C. 10,000 mm
- D. 100,000 mm
Correct answer: B
Rationale: The correct answer is B: 1,000 mm. This is because there are 1,000 millimeters in a meter. To convert from meters to millimeters, you need to multiply by 1,000. Choices A, C, and D are incorrect. A meter is equivalent to 1,000 millimeters, not 100 (A), 10,000 (C), or 100,000 (D) millimeters.
5. Which of the following is NOT a function of the nervous system?
- A. Detecting touch
- B. Regulating body temperature
- C. Producing insulin
- D. Controlling muscle movement
Correct answer: C
Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.
