ATI TEAS 7 Science Sample Test Questions

Question 1:

Which of the following statements accurately describes the structure of an atom?

A. Protons are negatively charged particles located in the nucleus.

B. Electrons have a mass nearly equal to that of protons and neutrons.

C. Neutrons are positively charged particles found outside the nucleus.

D. Electrons occupy energy levels or shells surrounding the nucleus.

Correct answer: D

Explanation: The structure of an atom consists of a positively charged nucleus composed of protons and neutrons, while negatively charged electrons occupy energy levels or shells surrounding the nucleus.

Question 2:

Which of the following diseases is caused by a deficiency of vitamin D?

A. Scurvy

B. Rickets

C. Anaemia

D. Osteoporosis

Correct answer: B

Explanation: Rickets is a disease caused by a deficiency of vitamin D. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to weak and deformed bones.

Question 3:

An unknown element is found to contain 45 protons and an atomic mass of 64. What is its atomic number?

A. 19

B. 45

C. 64

D. 109

Correct answer: B

Explanation: The atomic number of an element corresponds to the number of protons in its nucleus. In this case, the element has 45 protons, so its atomic number is also 45.

Question 4:

Which of the following diseases is caused by iron deficiency?

A. Scurvy

B. Anaemia

C. Osteoporosis

D. Rickets

Correct answer: B

Explanation: Anaemia is caused by a lack of iron, which is required for the production of red blood cells. Inadequate iron can lead to decreased oxygen-carrying capacity and symptoms such as fatigue and weakness.

Question 5:

An unknown element is found to contain 10 protons and an atomic mass of 20. What is its atomic number?

A. 10

B. 20

C. 30

D. 40

Correct answer: A

Explanation: The atomic number of an element corresponds to the number of protons in its nucleus. In this case, the element has 10 protons, so its atomic number is also 10.

Question 6:

Which of the following glands is responsible for producing the hormone insulin?

A. Pituitary gland

B. Thyroid gland

C. Pancreas

D. Adrenal glands

Correct answer: C

Explanation: The pancreas is an organ in the endocrine system that produces the hormone insulin. Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose from the bloodstream into cells.

Question 7:

Which of the following is responsible for transmitting signals between neurons in the nervous system?

A. Neurotransmitters

B. Hormones

C. White blood cells

D. Red blood cells

Correct answer: A

Explanation: Neurotransmitters are chemical messengers that transmit signals between neurons in the nervous system. They are released from the synaptic vesicles of one neuron and bind to receptors on another neuron, facilitating the transmission of nerve impulses.

Passing the ATI TEAS 7 Science test requires preparation, focus, and strategy. Here are some tips to help you prepare for and pass the exam:

Understand the Test Format

Learn the format of the ATI TEAS Science exam. Review the number of questions, the amount of time you have, and the types of questions to help you get ready.

The TEAS requires you to recall many science facts. In fact, the key words will tell you what science you're being tested on and what facts you need to give. 

You may be given data or a process description to evaluate an experiment or draw a conclusion.

Give yourself enough time to study every question, which may be in the form of a sentence, a table, or a figure. When you take a look at the options given for each question, it will tell you the science subject that’s been tested. 

Study the Content Areas

Review the most important parts of the science test, like anatomy and physiology, biology, chemistry, and scientific reasoning. Use reliable study materials and textbooks to learn a lot about these topics.

Make a study schedule that gives each topic enough time. Break topics into manageable chunks and dedicate study sessions to each topic.

The TEAS tests a lot of different areas of science. So, when you begin a new question, give yourself the time you need to figure out what the question is about. Is this about the nervous system? Reproductive system? Once you know, you should think about what you already know about the subject.

Check the question above for more information. It will answer the question or help you figure it out. Watch out! Knowing the material but missing the question because you misread a graph's axis or called the independent variable the dependent variable would be disappointing.

Use Practice Tests

Practice ATI TEAS Science tests to learn the format and test your knowledge. To simulate the test, take timed practice tests.

Review your practice test answers and check how you have performed. Focus on weaknesses during study sessions. If you know the right answer before looking at the answer choices, you won't choose a wrong answer that looks similar or related. It's possible you don't know the scientific facts. Even in these cases, review what you remember. This will help you eliminate obvious wrong answers and improve your accuracy.

Choose the answer that matches what you think is the right answer. If you couldn't make a guess, get rid of the answers that have to do with a different organ system or idea. This lets you make a strategic guess from the remaining choices.

Practice Critical Thinking Skills

On the science test, you have to think critically and solve problems a lot. Learn how to analyze data, read graphs and charts, and draw conclusions from scientific information.

If you come across ideas or topics that are hard to understand, don't be afraid to ask for help from teachers, tutors, or online forums. If you understand the main ideas, you will do better overall.

On the day of the test, get there early, bring the right ID and materials, and keep a good attitude. Pay close attention to the test instructions and take the test at a steady pace.

Remember that your chances of doing well on the ATI TEAS Science test will increase if you study regularly and work hard, and if you practice a lot.

Follow these tips and prepare to pass the ATI TEAS 7 Science test and achieve your health sciences academic goals.
