TEAS Practice Test Science

Correct Answer: B

Rationale: The correct answer is B: Scapula. Flat bones are thin, flattened bones that provide protection and allow for muscle attachment. The scapula fits this description as it is a thin, flat bone located on the back of the shoulder. The other choices (A: Femur, C: Humerus, D: Tibia) are long bones that are not thin and flat like flat bones. The femur, humerus, and tibia are all weight-bearing bones with a different shape and function compared to flat bones.

Correct Answer: B

Rationale: The correct answer is B because tracking drug dosage and blood levels is essential for quantitative research, providing measurable data for analysis. This method allows for precise measurement and statistical analysis, ensuring objective results. Patient narratives (A) lack quantifiability, making data analysis challenging. Observing physical changes (C) is subjective and doesn't provide quantitative data. Writing journal notes (D) is qualitative and doesn't involve numerical data for quantitative research.

Correct Answer: D

Rationale: The correct answer is D: Artificially acquired active immunity. Vaccines stimulate the body's immune system to produce antibodies and memory cells, providing long-lasting protection against specific diseases. This type of immunity is acquired through deliberate exposure to antigens in vaccines, making it artificial and active. A: Naturally acquired passive immunity is when antibodies are passed from mother to baby, providing temporary protection but not long-lasting immunity like vaccines. B: Artificially acquired passive immunity involves receiving pre-made antibodies, providing immediate but short-lived protection, not the prolonged immunity provided by vaccines. C: Naturally acquired active immunity is developed through natural exposure to pathogens, which is different from the intentional exposure to antigens in vaccines.

Correct Answer: D

Rationale: The correct answer is D: Temporal lobe. The temporal lobe is responsible for processing auditory sounds as it contains the primary auditory cortex. This area interprets and processes sound information received from the ears. The frontal lobe (A) is involved in higher cognitive functions, the occipital lobe (B) is responsible for processing visual information, and the parietal lobe (C) is involved in sensory processing and spatial awareness. Therefore, the temporal lobe is the correct choice for processing auditory sounds.

Correct Answer: B

Rationale: The correct answer is B: Artery. Arteries are responsible for carrying oxygenated blood from the heart to the body. Arteries have thick walls and are designed to withstand the high pressure generated by the pumping action of the heart. Oxygenated blood is pumped out of the heart through the aorta, the largest artery in the body, and then distributed to various parts of the body through smaller arteries. A: Veins carry deoxygenated blood back to the heart. C: Capillaries are tiny blood vessels where the exchange of oxygen and nutrients occurs. D: Lymphatic vessels are responsible for transporting lymph, not oxygenated blood. In summary, arteries are specifically designed to carry oxygenated blood away from the heart, making them the correct choice in this scenario.
