TEAS Practice Math Test

1. A lab technician took 100 hairs from a patient to conduct several tests. The technician used 1/7 of the hairs for a drug test. How many hairs were used for the drug test? (Round your answer to the nearest hundredth.)

Correct answer: C

Rationale: To find how many hairs were used for the drug test, you need to calculate 1/7 of 100. 1/7 of 100 is 14.2857, which rounds to 14.29 when rounded to the nearest hundredth. Therefore, 14.29 hairs were used for the drug test. Choice A is incorrect as it does not account for rounding to the nearest hundredth. Choices B and D are incorrect as they do not accurately reflect the calculated value after rounding.

2. Divide 52 by 27 and 51 by 27 and simplify.

Correct answer: A

Rationale: To divide 52 by 27 and 51 by 27, you get 52/27 and 51/27, respectively. When simplified, 52/27 is the correct answer. The other choices, 51/27, 52/29, and 51/29, are incorrect because they do not reflect the correct result of dividing the given numbers.

3. Which of the following is true regarding T cells?

Correct answer: D

Rationale: The correct answer is D: T cells are a specialized type of white blood cell that play a crucial role in the immune response. They are produced in the bone marrow and mature in the thymus gland. T cells help coordinate and regulate the immune response to pathogens and foreign substances by interacting with other immune cells. Choices A, B, and C are incorrect. T cells are not exclusively seen in individuals with leukemia; they are a normal component of the immune system found in healthy individuals. While it is true that T cells are a specialized type of white blood cell, the key characteristic being tested in this question is their role in the immune response. Lastly, T cells do mature in the thymus, but this alone does not encompass the full scope of their function in the immune system.

4. Which of the following is an effect of high blood pressure?

Correct answer: C

Rationale: The correct answer is C: Renal vessel damage. High blood pressure can lead to damage in blood vessels throughout the body, including the kidneys. When blood vessels in the kidneys are affected, it can impair kidney function and potentially lead to kidney disease. Smoking (Choice A) and excessive dietary salt (Choice B) can contribute to high blood pressure but are not direct effects of high blood pressure itself. Older age (Choice D) is a risk factor for developing high blood pressure but is not a direct effect of high blood pressure.

5. Which of the following statements best describes Newton's first law of motion?

Correct answer: A

Rationale: Newton's first law of motion, also known as the law of inertia, states that an object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by an external force. This principle highlights the concept of inertia, which is the tendency of objects to resist changes in their state of motion. Option A accurately captures this fundamental aspect of Newton's first law. Options B, C, and D describe Newton's second law, third law, and the relationship between force, acceleration, and mass, respectively. Therefore, options B, C, and D are incorrect as they pertain to different laws formulated by Newton.
