ATI TEAS Science Questions
1. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?
- A. The patient says he feels pain.
- B. The patient says he has stabbing pain.
- C. The patient's temperature is 101.7°F.
- D. The patient reports that he had a fever yesterday.
Correct answer: C
Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.
2. Differentiate between genotype and phenotype in the context of gene expression.
- A. Genotype refers to the physical manifestation of a trait, while phenotype represents its underlying genetic makeup.
- B. Genotype encompasses the spectrum of possible traits encoded by an organism's genes, while phenotype signifies the specific trait observed.
- C. Genotype denotes the presence of dominant alleles, while phenotype reflects the influence of recessive alleles.
- D. There is no distinction; both terms are interchangeable.
Correct answer: B
Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses. - Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment. - While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits. - Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.
3. Which division of the nervous system is responsible for the 'fight or flight' response, preparing the body to respond to stressful situations?
- A. Somatic nervous system
- B. Autonomic nervous system
- C. Peripheral nervous system
- D. Central nervous system
Correct answer: B
Rationale: The autonomic nervous system is correctly identified as the division responsible for the 'fight or flight' response, which readies the body to react to stressful situations. This system regulates involuntary bodily functions, such as heart rate, pupil dilation, and adrenaline release during stress. The somatic nervous system controls voluntary movements and skeletal muscle activity, not the automatic responses seen in the 'fight or flight' reaction. The peripheral nervous system connects the central nervous system to the body's organs and limbs, facilitating communication, while the central nervous system, comprising the brain and spinal cord, serves as the primary control center of the body, integrating and processing information.
4. What is the primary function of the small intestine?
- A. To absorb water
- B. To absorb nutrients
- C. To store waste
- D. To produce enzymes
Correct answer: B
Rationale: The correct answer is B: "To absorb nutrients." The small intestine's primary function is to absorb nutrients from digested food. It plays a crucial role in the digestion and absorption of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals, which are essential for the body's functions and energy production. Choice A, "To absorb water," is incorrect because the absorption of water primarily occurs in the large intestine. Choice C, "To store waste," is incorrect as waste is stored in the large intestine before elimination. Choice D, "To produce enzymes," is incorrect because while the small intestine does receive enzymes from other organs to aid in digestion, its primary role is not enzyme production.
5. What is a characteristic property of acids?
- A. Bitter taste
- B. Sour taste
- C. Slippery feel
- D. Sweet taste
Correct answer: B
Rationale: The correct characteristic property of acids is a sour taste. Acids release hydrogen ions when dissolved in water, giving them a sour taste. Bitter taste is a property associated with bases, not acids. Slippery feel is a characteristic property of bases, due to their soap-like nature. Sweet taste does not accurately describe the characteristic property of acids, as they are known for their sour taste.
