ATI TEAS Science Questions

1. What is the cycle of infection?

Correct answer: A

Rationale: The correct answer is A: 'Reservoir host, means of exit, means of transmission, means of entrance, susceptible host.' This cycle of infection involves the pathogen starting in a reservoir host, exiting through a means, being transmitted to another host, entering the new host through a means, and ultimately infecting the susceptible host. Choices B, C, and D are incorrect because they do not follow the correct sequence of events in the cycle of infection.

2. Using the chart below, which equation describes the relationship between x and y?

Correct answer: B

Rationale: The correct equation that describes the relationship between x and y based on the chart is y = 3x. This is because each y-value in the chart is 3 times the x-value. Choice A (x = 3y) is incorrect as it implies x is 3 times y, which is the opposite of the relationship shown in the chart. Choice C (y = 1/3x) is incorrect since the relationship in the chart indicates y is 3 times x, not a third of x. Choice D (x/y = 3) is incorrect as it represents a ratio between x and y equal to 3, which is not in line with the relationship depicted in the chart.

3. Which of the following units is used to express concentration as a mass of solute per unit volume of solution?

Correct answer: A

Rationale: Molality (m) is the unit used to express concentration as a mass of solute per unit volume of solution. It is calculated by dividing the mass of solute in grams by the mass of the solvent in kilograms. Molality is preferred over molarity when there are large temperature variations as it is temperature-independent, making it a more accurate measure of concentration. Molarity (B) is the unit used to express concentration as moles of solute per liter of solution, weight percent (C) is the mass of solute per 100 parts of the total mass of the solution, and parts per million (D) is used to express very small concentrations where 1 ppm is equivalent to 1 mg of solute per liter of solution.

4. Which of the following water-soluble vitamins is NOT synthesized in the large intestine?

Correct answer: A

Rationale: The correct answer is A: B6. Vitamin B6 is not synthesized in the large intestine, while biotin, pantothenic acid (Vitamin B5), and Vitamin K can be synthesized by gut microflora. Biotin, B5, and K are examples of water-soluble vitamins that can be produced in the large intestine, but B6 needs to be obtained through dietary sources. Therefore, B6 is the correct answer as it is not synthesized within the large intestine, unlike the other options.

5. The lake was clear and shimmering, and it was such a friendly day; therefore, he dove right in. Which of the following describes the grammar problem in the sentence above?

Correct answer: A

Rationale: The correct answer is A: Ambiguous word choice. In this sentence, the word 'friendly' is ambiguous and does not clearly convey the intended meaning. The context of the sentence suggests that 'friendly' is used inappropriately to describe a day, making the sentence unclear. Choices B, C, and D are incorrect because the issue in the sentence does not relate to transition words, tense disagreement, or an incomplete sentence.
