Practice TEAS Science Test Questions
Question 1 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 2 of 5
Which of the following is the space between the lungs?
Correct Answer: A
Rationale: The correct answer is A: Mediastinum. The mediastinum is the space between the lungs that contains vital structures such as the heart, major blood vessels, esophagus, and trachea. It separates the lungs into right and left compartments. The pericardial cavity (B) is the space that surrounds the heart within the mediastinum. The pleural cavity (C) is the space between the lungs and the chest wall, not between the lungs themselves. Thoracic space (D) is a vague term and does not specifically refer to the space between the lungs.
Question 3 of 5
What is the function of the Vas Deferens?
Correct Answer: D
Rationale: The correct answer is D because the Vas Deferens connects each testis to the urethra, allowing sperm to travel from the testes to the urethra during ejaculation. This tube plays a crucial role in the male reproductive system by transporting sperm for ejaculation. A is incorrect because the production of fluid to increase sperm mobility is carried out by the seminal vesicles and prostate gland. B is incorrect because the site where the egg matures is the fallopian tubes in females. C is incorrect because controlling urine flow is the function of the urethra and muscles in the bladder, not the Vas Deferens.
Question 4 of 5
Which blood type is known as the universal donor?
Correct Answer: D
Rationale: The correct answer is D: Type O. Type O blood lacks both A and B antigens, making it compatible with all blood types. As a result, it can be safely transfused to individuals with any blood type, earning it the title of the universal donor. Choice A (Type A) has A antigens, Choice B (Type B) has B antigens, and Choice C (Type AB) has both A and B antigens, making them not suitable for universal donation.
Question 5 of 5
Which region of the small intestine is the primary site of absorption?
Correct Answer: B
Rationale: The correct answer is B: Jejunum. The jejunum is the primary site of absorption in the small intestine due to its extensive surface area, presence of villi and microvilli that increase absorption capacity, and higher blood supply compared to other regions. It is where most nutrients such as carbohydrates, proteins, and fats are absorbed. The duodenum (A) is mainly responsible for initial digestion, the ileum (C) absorbs bile salts, vitamin B12, and some nutrients, and the cecum (D) is part of the large intestine and is not involved in nutrient absorption.
