Math Practice TEAS Test
1. How many pints are in a gallon?
- A. 2 pints
- B. 4 pints
- C. 8 pints
- D. 16 pints
Correct answer: C
Rationale: The correct answer is C: 8 pints. In the U.S. customary system, there are 8 pints in a gallon. This conversion is essential to know for various activities like cooking, measuring liquids, or understanding container volumes. Choice A, 2 pints, is incorrect as it represents half a gallon. Choice B, 4 pints, is incorrect as it represents a half-gallon or a quart. Choice D, 16 pints, is incorrect as it represents two gallons. Therefore, the correct answer is C, 8 pints.
2. What is a temporary loss of consciousness due to insufficient blood flow to the brain called?
- A. Stroke
- B. Seizure
- C. Syncope (fainting)
- D. Coma
Correct answer: C
Rationale: Syncope, also known as fainting, is a temporary loss of consciousness caused by insufficient blood flow to the brain. It results from a brief interruption in the brain's blood supply, leading to a temporary loss of consciousness. The correct answer is C. A stroke, option A, is caused by a blockage or rupture of blood vessels in the brain, not insufficient blood flow. Seizure, option B, involves a sudden surge of electrical brain activity, not reduced blood flow. Coma, option D, is characterized by prolonged unconsciousness, not a temporary loss of consciousness due to insufficient blood flow.
3. What word best describes the organization of this passage?
- A. Modeling
- B. Hypothesizing
- C. Explaining
- D. Observing
Correct answer: C
Rationale: The correct answer is 'Explaining.' The passage is structured in an explanatory manner, providing a detailed account of how a plunger works. It explains the process step by step, from the initial depression of the plunger to the increase in pressure inside the clogged pipe. 'Modeling' and 'Observing' are not suitable choices as the passage does not involve creating models or direct observations. 'Hypothesizing' is also incorrect as the passage focuses on describing the functioning of a plunger rather than proposing or discussing potential hypotheses.
4. Which of the following hormones helps regulate blood pressure by affecting kidney function?
- A. Insulin
- B. Testosterone
- C. Renin
- D. Estrogen
Correct answer: C
Rationale: Renin is the hormone that helps regulate blood pressure by affecting kidney function. It is released by the kidneys in response to low blood pressure or low blood volume. Renin plays a crucial role in the renin-angiotensin-aldosterone system, which is responsible for regulating blood pressure and fluid balance in the body. Insulin, testosterone, and estrogen do not directly impact blood pressure regulation through kidney function. Insulin is involved in regulating glucose metabolism, testosterone is a male sex hormone, and estrogen is a female sex hormone. Therefore, the correct answer is Renin (Choice C) because of its specific role in blood pressure regulation through kidney function.
5. What is the primary function of the nervous system?
- A. To produce hormones
- B. To transmit electrical impulses
- C. To carry oxygen
- D. To transport nutrients
Correct answer: B
Rationale: The correct answer is B: To transmit electrical impulses. The primary function of the nervous system is to transmit electrical impulses and coordinate body activities. While hormones are produced by the endocrine system, not the nervous system, oxygen transportation is mainly carried out by the respiratory system, and nutrient transport is primarily the role of the circulatory system. Therefore, choices A, C, and D are incorrect as they do not align with the primary function of the nervous system.
