Science TEAS Practice Test Questions
Question 1 of 5
A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?
Correct Answer: A
Rationale: The correct answer is A because it provides a logical and evidence-based explanation for the need for weight loss. Losing weight can lower blood pressure, increase energy levels, and promote overall health, which are all scientifically proven benefits. Choice B is irrelevant to the health benefits of weight loss. Choice C focuses on social perceptions rather than health benefits. Choice D oversimplifies the process of losing weight, which is not always easy and requires effort and commitment.
Question 2 of 5
Which of the following structures connects muscle to bone?
Correct Answer: B
Rationale: The correct answer is B: Tendons. Tendons are fibrous connective tissues that attach muscle to bone, allowing for movement. Ligaments (A) connect bone to bone, muscles (C) are the tissues responsible for movement, and bones (D) are the rigid structures that make up the skeletal system. Tendons play a crucial role in transmitting the force generated by muscles to move bones, making them the correct choice in this scenario.
Question 3 of 5
Which of the following is a representation of a natural pattern or occurrence that is difficult or impossible to experience directly?
Correct Answer: B
Rationale: The correct answer is B: A model. A model is a representation of a natural pattern or occurrence that simplifies complex systems to make them easier to understand and study. Models can simulate natural phenomena that are difficult or impossible to experience directly, allowing scientists to make predictions and test hypotheses. The other choices are incorrect because: A: A theory is an explanation based on evidence and reasoning, not necessarily something difficult to experience directly. C: A law describes a recurring phenomenon but may not involve a representation or simulation of the phenomenon. D: An observation is a direct act of seeing or noting something, not a representation of a complex natural pattern.
Question 4 of 5
In the 18th century, women were more likely to die in childbirth compared to the 21st century. What is a possible explanation for why women are less likely to die in childbirth in the present age?
Correct Answer: D
Rationale: The correct answer is D because all the statements provide reasonable explanations for the decrease in mortality during childbirth in the 21st century. A: Cesarean sections can be life-saving in cases of complications like prolonged labor or fetal distress. B: Monitoring tools help detect issues early, allowing for timely interventions and prevention of complications. C: Good hand hygiene reduces the risk of infections that could lead to maternal mortality. Therefore, by combining the advancements in cesarean sections, monitoring tools, and infection prevention practices, modern healthcare has significantly reduced maternal mortality rates compared to the 18th century.
Question 5 of 5
Long bones are one of the five major types of bones in the human body. Which of the following bones are long bones?
Correct Answer: D
Rationale: The correct answer is D because the ulna, fibula, and humerus are classified as long bones. Long bones are characterized by their elongated shape, with a shaft and two distinct ends. The ulna and humerus are long bones of the upper extremities, while the fibula is a long bone of the lower extremity. A, the sacrum, is a triangular bone at the base of the spine and is classified as a flat bone. B, the clavicle, is also a flat bone that connects the sternum to the scapula. C, the patella, is a sesamoid bone located in the knee joint and is not classified as a long bone. Therefore, the correct answer is D, as the ulna, fibula, and humerus are examples of long bones based on their structure and function.
