ATI TEAS Science Test Questions
Question 1 of 5
In order to verify if a particular drug is responsible for the recovery of individuals with a disorder, what procedure would be most effective in testing its effectiveness?
Correct Answer: A
Rationale: The most effective procedure in testing whether the drug is responsible for the recovery is to ensure that neither the subjects nor the investigators know which subjects are given the drug and which are given the placebo. This method is known as a double-blind study, which helps eliminate biases and ensures that the results are reliable and not influenced by expectations or beliefs. By keeping both the subjects and investigators unaware of who is receiving the drug or placebo, the study can accurately determine the true impact of the drug on recovery. Choice B is incorrect as it only prevents the subjects from knowing which treatment they are receiving, allowing for potential bias from the investigators. Choice C is also incorrect as it allows for potential bias from the subjects. Choice D is incorrect as full knowledge of treatment allocation can introduce bias and affect the study's validity.
Question 2 of 5
When defending a scientific argument, which technique is most effective?
Correct Answer: B
Rationale: The most effective technique when defending a scientific argument is to show the results of scientific experiments that support your argument. In the realm of science, evidence-based support is crucial. By presenting concrete data and experimental results, you provide a convincing and reliable foundation for your argument. This method allows others to review, replicate, and verify the findings, thus strengthening the credibility of your position. Choices A, C, and D are not as effective as choice B because citing other scientists who agree with your argument (Choice A) may not carry the same weight as empirical evidence, describing your scientific credentials, education, and past accomplishments (Choice C) may not directly address the validity of your argument, and pointing out that no one has come up with a proven alternative explanation (Choice D) does not provide direct evidence supporting your argument.
Question 3 of 5
Where is the abdominopelvic cavity in relation to the thoracic cavity?
Correct Answer: D
Rationale: The abdominopelvic cavity is located inferior to the thoracic cavity. The thoracic cavity contains organs like the heart and lungs, while the abdominopelvic cavity includes the abdomen and pelvis regions. Therefore, the correct answer is D, as the abdominopelvic cavity is positioned below (inferior to) the thoracic cavity. Choice A (Dorsal) is incorrect as it refers to the backside of the body. Choice B (Ventral) is incorrect as it refers to the front side of the body. Choice C (Superior) is incorrect as it indicates a position above the thoracic cavity, which is not the case.
Question 4 of 5
Which of the following organs does not belong with the others?
Correct Answer: B
Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.
Question 5 of 5
How does water affect the temperature of a living thing?
Correct Answer: B
Rationale: Water has a high specific heat capacity, which means it can absorb and release a large amount of heat energy without causing a significant change in temperature. This property allows water to help regulate the temperature of living things by buffering against sudden temperature changes in the environment. Overall, water helps to maintain a stable temperature within living organisms, which is crucial for their survival and physiological processes. Choices A, C, and D are incorrect because water's high specific heat capacity enables it to stabilize temperatures rather than increasing, decreasing, or having no effect on them.
