Reading Comprehension HESI A2 Practice Test

1. What is the meaning of the word viable as used in the last paragraph?

A. Reasonable
B. Unresolved
C. Contemporary
D. Consistent

Correct answer: A

Rationale: In the context of the passage, "viable" means reasonable or feasible, referring to the acceptability of acupuncture as a treatment option based on the study's results. This definition aligns with the implications made in the conclusion of the study, thus supporting option A.

2. What is the best description for the term anodyne?

A. Emulsified
B. Liquefied
C. Contaminated
D. Painkilling

Correct answer: D

Rationale: The term 'anodyne' refers to something that relieves or alleviates pain or discomfort. Therefore, the best description for anodyne is 'painkilling.' Choices A (Emulsified), B (Liquefied), and C (Contaminated) are incorrect as they do not accurately represent the meaning of anodyne.

3. A restricted diet is ___________.

A. low in fat
B. vegetarian
C. banned
D. limited

Correct answer: D

Rationale: A restricted diet is limited in some way, such as reducing the intake of certain foods, food groups, or nutrients. It may involve limitations on quantity, frequency, or types of foods consumed. This restriction could be related to health factors, allergies, sensitivities, ethical reasons, or personal preferences. Choice A, 'low in fat,' is too specific and does not encompass the broad concept of restriction in a diet. Choice B, 'vegetarian,' refers to a specific dietary pattern but does not necessarily indicate restriction. Choice C, 'banned,' is incorrect as it implies a complete prohibition rather than limitation, which is characteristic of a restricted diet.

4. Which connective tissue type attaches muscles to bones?

A. Ligaments
B. Tendons
C. Cartilage
D. Fascia

Correct answer: B

Rationale: Tendons are the correct answer. They are strong connective tissues that connect muscles to bones, allowing movement when muscles contract. Ligaments connect bones to other bones, providing joint stability. Cartilage is a firm, flexible connective tissue present in joints and the outer ear. Fascia is a connective tissue that surrounds muscles, blood vessels, and nerves, offering support and protection. Therefore, the correct tissue type that connects muscles to bones is tendons.

5. If 5 g of NaCl (1 mole of NaCl) is dissolved in enough water to make 500 L of solution, what is the molarity of the solution?

A. 1.0 M
B. 2.0 M
C. 11.7 M
D. The answer cannot be determined from the information given.

Correct answer: C

Rationale: Molarity is defined as the number of moles of solute per liter of solution. In this case, 5 g of NaCl represents 1 mole of NaCl. Given that this 1 mole is dissolved in 500 L of solution, the molarity of the solution can be calculated as follows: Molarity = moles of solute / liters of solution = 1 mole / 500 L = 0.002 M. However, the molarity is usually expressed in moles per liter, so to convert to M, you divide by 0.085 L (which is 500 L in liters) to get 11.7 M. Choice A is incorrect because the molarity is not 1.0 M. Choice B is incorrect because the molarity is not 2.0 M. Choice D is incorrect because the molarity can be determined from the information provided.
