Practice TEAS Science Test Questions
Question 1 of 5
Which of the following is an example of a ball-and-socket joint?
Correct Answer: B
Rationale: The correct answer is B: Hip. A ball-and-socket joint allows for a wide range of motion in multiple directions. The hip joint fits this description, with the rounded head of the femur fitting into the socket of the pelvis. This joint enables movements like flexion, extension, abduction, adduction, and rotation. The other choices, such as the knee (A), elbow (C), and wrist (D), are not ball-and-socket joints. The knee is a hinge joint, the elbow is a hinge joint as well, and the wrist is a condyloid joint.
Question 2 of 5
Which of the following is an example of an organ?
Correct Answer: A
Rationale: The correct answer is A: Skin. An organ is a group of tissues that work together to perform specific functions in the body. Skin is the body's largest organ, made up of different layers that serve various functions like protection, sensation, and regulation of body temperature. Neuron (B) is a cell type, brainstem (C) is a part of the brain, and DNA (D) is a molecule, not an organ. Skin best fits the definition of an organ, making it the correct choice.
Question 3 of 5
What is the function of the lymphatic system?
Correct Answer: B
Rationale: The correct answer is B: To filter waste from the blood. The lymphatic system includes lymph nodes and vessels that help filter out waste, toxins, and pathogens from the blood. Lymphocytes in the lymph nodes also play a key role in immune responses. The other choices (A, C, D) are incorrect because the lymphatic system is not responsible for transporting oxygen (A), producing red blood cells (C), or regulating body temperature (D).
Question 4 of 5
A researcher wants to conduct qualitative research. Which method should they use?
Correct Answer: A
Rationale: The correct answer is A: Collecting patient narratives. Qualitative research aims to understand individuals' experiences and perceptions in-depth. Collecting patient narratives allows for capturing subjective insights, emotions, and personal perspectives. This method helps uncover themes, patterns, and nuances in participants' stories, providing rich data for analysis. B: Tracking drug dosage and blood levels is quantitative research, focusing on numerical data. C: Observing physical changes is more suitable for quantitative or observational research. D: Writing journal notes about the research experience is reflective and may provide insights but does not capture the essence of qualitative research, which is to explore subjective experiences.
Question 5 of 5
What is the ultimate end product of glucose breakdown in glycolysis?
Correct Answer: C
Rationale: The correct answer is C: Pyruvic acid. In glycolysis, glucose is broken down into pyruvic acid. This process involves a series of enzymatic reactions that result in the production of pyruvic acid, which is a crucial intermediate in cellular respiration. Pyruvic acid can then enter the citric acid cycle to further extract energy in the form of ATP. Rationale for other choices: A: ATP is produced during glycolysis, but it is not the end product. B: NADPH is not the end product of glucose breakdown in glycolysis; it is a reducing agent used in various metabolic pathways. D: Oxygen is not directly produced as a result of glucose breakdown in glycolysis; oxygen is utilized in later stages of cellular respiration.
