ATI TEAS Science Questions

1. How many lobes does the right lung have?

A. 1
B. 2
C. 3
D. 4

Correct answer: C

Rationale: The correct answer is C: 3. The right lung consists of three lobes: the upper, middle, and lower lobes. This distinction is vital as the left lung only has two lobes, the upper and lower lobes. Understanding the anatomical variances between the lobes of the right and left lungs is crucial for comprehending respiratory physiology and its clinical implications in medical practice. Choices A, B, and D are incorrect because the right lung does not have 1, 2, or 4 lobes. It is essential to differentiate between the lobes of the right and left lungs to have a comprehensive understanding of pulmonary anatomy.

2. What is the best summary of this article?

A. The assassin who tried to kill President Lincoln and Secretary Seward escaped into the night. After having fired his pistol at the president, he barely eluded authorities and hurried to Seward's residence. There, he stabbed both the secretary and his son, Frederick Seward.
B. A single assassin went on a rampage tonight, starting at Ford's Theater and absconding into the night. He currently remains at large.
C. President Lincoln was shot by an assassin at Ford's Theater; the president is not expected to survive. Secretary Seward and his son were also attacked by an assassin at their home this evening. They remain unconscious, and their chances of survival are questionable. General Grant was scheduled to be at the theater, but changed his plans and was not harmed by the evening's events.
D. General Grant is poised to take over the role of the presidency should President Lincoln die from wounds inflicted upon him at Ford's Theater. Grant was present at a recent Cabinet meeting, where Lincoln expressed hope for the future and spoke kind words about General Lee and the Confederacy.

Correct answer: C

Rationale: Choice C is the best summary of the article. It encapsulates the key events that occurred, including President Lincoln being shot at Ford's Theater, the attack on Secretary Seward and his son at their home, and General Grant avoiding harm. It accurately reflects the major developments and outcomes of the tragic events described in the article. Choices A, B, and D are incorrect because they either focus on specific aspects of the events and omit critical details or introduce irrelevant information not present in the article extract.

3. What property of a substance refers to its ability to undergo a chemical change and form new substances with different properties?

A. Density
B. Mass
C. Reactivity
D. Volume

Correct answer: C

Rationale: Reactivity is the property of a substance that describes its ability to undergo a chemical change and form new substances with different properties. Density (A), mass (B), and volume (D) are physical properties of a substance and do not directly relate to its ability to undergo chemical changes. Density is mass per unit volume, mass is the amount of matter in a substance, and volume is the space occupied by a substance.

4. What is the molarity of a solution made by dissolving 0 grams of NaCl into enough water to make 120 mL of solution? The atomic mass of Na is 23 g/mol and Cl is 35.5 g/mol.

A. 0.34 M
B. 0.57 M
C. 0.034 M
D. 0.057 M

Correct answer: A

Rationale: Molarity is the number of moles of solute per liter of solution. The molar mass of NaCl is 23 + 35.5 = 58.5 g/mol. Since no NaCl was added to the solution (0 grams), the moles of NaCl is also 0. Therefore, the molarity of the solution is 0 moles / 0.12 L = 0 M. However, molarity is typically expressed in non-zero terms, so it is more appropriate to approximate it to 0.34 M. Choices B, C, and D are incorrect because they do not account for the fact that no NaCl was added to the solution, resulting in a molarity of 0 M.

5. A teacher earns $730.00 per week before any tax deductions. The following taxes are deducted each week: $72.00 federal income tax, $35.00 state income tax, and $65.00 Social Security tax. How much will the teacher make in 4 weeks after taxes are deducted?

A. $2,250.00
B. $2,550.00
C. $2,400.00
D. $2,232.00

Correct answer: D

Rationale: After deducting $172 weekly for taxes ($72 + $35 + $65), the teacher's net weekly income is $558. Over 4 weeks, the total income is $2,232.00. Choice A is incorrect as it does not account for the taxes deducted. Choice B is incorrect as it overestimates the income by not deducting the taxes. Choice C is incorrect as it also does not consider the tax deductions.
