ATI TEAS 7 Science Questions

Question 1 of 5

What is the maximum volume of air that the lungs can hold after a full forced inhalation?

Correct Answer: C

Rationale: The correct answer is C: Total lung capacity. Total lung capacity is the maximum volume of air the lungs can hold after a full forced inhalation. It includes all the volumes within the lungs, such as tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. It is the sum of vital capacity and residual volume. Inspiratory capacity (A) is the maximum volume of air that can be inhaled after a normal exhalation. Tidal volume (B) is the volume of air inspired or expired during normal breathing. Vital capacity (D) is the maximum volume of air that can be exhaled after a maximum inhalation, not the total volume the lungs can hold.

Question 2 of 5

In the process of osmosis, the solvent moves from an area of...

Correct Answer: D

Rationale: In osmosis, solvent moves from an area of low solute concentration to high solute concentration to equalize concentration. This is due to the principle of diffusion where molecules move from high to low concentration. Choice D is correct as it aligns with this principle. Choice A is incorrect because osmosis involves solvent movement, not solute movement. Choices B and C are incorrect as temperature does not determine the direction of solvent movement in osmosis.

Question 3 of 5

Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

Correct Answer: C

Rationale: The correct answer is C: Holding urine in the bladder for long periods is NOT recommended for optimal urinary system health. When urine is held for a long time, it can increase the risk of urinary tract infections and bladder issues. It can also lead to bladder distension and potential damage to the bladder muscles. To maintain urinary system health, it is crucial to empty the bladder regularly to prevent bacterial growth and support proper bladder function. Choices A, B, and D are recommended practices for optimal urinary system health. Limiting high-sodium foods helps reduce the risk of kidney stones and hypertension, consuming cranberry juice can help prevent urinary tract infections, and regular moderate-intensity exercise promotes overall health, including the urinary system.

Question 4 of 5

Which of the following is used to record the measurable electrical activity of the brain?

Correct Answer: C

Rationale: The correct answer is C: Electroencephalogram (EEG). EEG is used to record the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to measure brain waves. A CAT scan (A) uses X-rays to create detailed images of the brain's structure, not its electrical activity. An MRI scan (B) uses magnetic fields to produce detailed images of the brain's anatomy, not its electrical activity. X-ray (D) is used to visualize bones and dense tissues, not brain activity. EEG is the only option that directly measures the brain's electrical activity, making it the correct choice.

Question 5 of 5

Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?

Correct Answer: D

Rationale: The correct answer is D because all the options are valid obstacles to achieving controlled nuclear fusion on Earth. Lack of suitable materials (A) is crucial due to extreme conditions, limited fusion fuels (B) can hinder sustained reactions, and containing plasma (C) is challenging to prevent energy loss. Therefore, all factors must be addressed for successful fusion energy production.
