ATI TEAS Science Questions Questions

Question 1 of 5

What is bile, where is it produced, where is it stored, and what is its function?

Correct Answer: B

Rationale: Bile is a digestive fluid produced in the liver, stored in the gallbladder, and it aids in the digestion of fats by emulsifying them. Emulsification helps to break down fats into smaller particles, facilitating their digestion by enzymes in the small intestine. Choice A is incorrect because bile is not produced in the pancreas, and it is not stored in the liver. Choice C is incorrect as bile is not produced in the stomach, and it does not neutralize acid. Choice D is also incorrect as bile is not produced in the gallbladder, and its primary function is not to break down proteins.

Question 2 of 5

Salts like sodium iodide (NaI) and potassium chloride (KCl) use what type of bond?

Correct Answer: A

Rationale: Salts like sodium iodide (NaI) and potassium chloride (KCl) use ionic bonds. Ionic bonds are formed between atoms with significantly different electronegativities, leading to the transfer of electrons from one atom to another. In the case of NaI and KCl, sodium (Na) and potassium (K) are metals that easily lose electrons to become positively charged ions, while iodide (I) and chloride (Cl) are nonmetals that readily accept electrons to become negatively charged ions. The attraction between the oppositely charged ions forms the ionic bond, which holds the compound together in a lattice structure. Disulfide bridges (option B) are covalent bonds formed between sulfur atoms in proteins, not in salts. Covalent bonds (option C) involve the sharing of electrons between atoms and are typically seen in molecules, not ionic compounds like salts. London dispersion forces (option D) are weak intermolecular forces that occur between all types of molecules but are not the primary type of bond in salts like NaI and KCl.

Question 3 of 5

As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

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.

Question 4 of 5

Which of the following is not a component of blood?

Correct Answer: D

Rationale: The correct answer is D: Cartilage. Cartilage is not a component of blood. Blood primarily consists of red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen, white blood cells are part of the immune system, and platelets are essential for blood clotting. Cartilage, on the other hand, is a type of connective tissue found in various parts of the body, such as the joints and nose, but it is not present in the blood. Therefore, choices A, B, and C are incorrect as they are components of blood, while choice D, Cartilage, is the correct answer as it is not a component of blood.

Question 5 of 5

Which muscle is voluntary, striated, and found attached to bones?

Correct Answer: B

Rationale: The correct answer is B, Skeletal muscle. Skeletal muscle is both voluntary and striated, as well as attached to bones, allowing for movement. Smooth muscle, on the other hand, is involuntary and typically found in the walls of internal organs, controlling functions like digestion. Cardiac muscle is also striated, but it is involuntary and specifically found in the heart, responsible for cardiac contractions to pump blood. 'Epithelial muscle' is an incorrect term; epithelial tissue is a type of tissue that forms the linings of various body surfaces and structures, not a muscle type.
