Reading Comprehension HESI A2

1. The author's reason for writing this piece seems to be to

Correct answer: D

Rationale: The author likely wrote this piece to inform the reader because the content is focused on providing information about the Golden Gate Bridge's history, construction, and significance. The text presents facts and details without attempting to persuade or entertain. The main purpose appears to be sharing useful or educational information rather than teaching, persuading, or entertaining.

2. Which connective tissue type attaches muscles to bones?

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.

3. Which mineral helps maintain fluid balance in the body?

Correct answer: A

Rationale: Potassium is the mineral that helps maintain fluid balance in the body. It plays a crucial role in regulating the amount of fluid inside and outside the body's cells, thereby helping to maintain proper hydration levels. Potassium works in conjunction with sodium to regulate fluid balance and is essential for proper muscle function, nerve transmission, and heart health. Cobalt, chromium, and sulfur do not play significant roles in maintaining fluid balance in the body, making them incorrect choices for this question.

4. During an isothermal (constant temperature) expansion, what is the work done by the gas on the surroundings?

Correct answer: D

Rationale: In an isothermal expansion, the temperature remains constant, meaning there is no change in internal energy. However, the gas still does work on the surroundings as it expands, and this work is positive. Since internal energy does not change, the correct answer is D, 'Positive and greater than the change in internal energy.' Choice A is incorrect because the work done is not equal to the change in internal energy. Choice B is incorrect as work is done during the expansion. Choice C is incorrect since the work done is not negative during an isothermal expansion.

5. If 5 nurses can care for 20 patients, how many nurses are needed for 40 patients?

Correct answer: B

Rationale: If 5 nurses can care for 20 patients, it means each nurse is responsible for 20/5 = 4 patients. To care for 40 patients, we divide the total patients by the number of patients each nurse can care for: 40/4 = 10 nurses. Therefore, 10 nurses are needed for 40 patients. Among the options, the closest number is 8 nurses, making it the correct answer. Choice A, 7 nurses, is insufficient. Choice C, 9 nurses, exceeds the required amount. Choice D, 10 nurses, matches the total number of nurses required, not the closest, making it incorrect.
