Reading Comprehension HESI A2 Practice Test

1. Which statement would not be inferred by the reader in the passage about MRSA?

Correct answer: D

Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.

2. What is the primary function of the immune system?

Correct answer: B

Rationale: The primary function of the immune system is to fight infections. It identifies and destroys pathogens like bacteria and viruses, protecting the body from harmful substances. While oxygen transportation is carried out by the respiratory system, energy production is mainly the role of the metabolic system, and body temperature regulation is managed by the thermoregulatory system. These functions are separate from the immune system's primary role of defending the body against infections.

3. A pencil measures 8cm long. What is this in mm?

Correct answer: A

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since 1 centimeter is equal to 10 millimeters. Therefore, 8 cm x 10 mm/cm = 80 mm. The pencil measures 8 cm, which is equivalent to 80 mm when converted. Choice A is correct as it correctly converts 8 cm to mm by multiplying it by 10. Choices B, C, and D are incorrect because they do not apply the correct conversion factor.

4. Which organelle is responsible for energy production in the cell?

Correct answer: B

Rationale: Mitochondria are the organelles responsible for energy production in the cell. They generate energy through cellular respiration, producing ATP, which is the primary energy currency of the cell. Known as the powerhouse of the cell, mitochondria play a vital role in meeting the energy demands of various cellular processes. The nucleus is responsible for storing genetic material, not energy production. Ribosomes are involved in protein synthesis, not energy production. The endoplasmic reticulum is involved in protein and lipid synthesis, as well as detoxification, but it is not primarily responsible for energy production.

5. What conclusion can the reader draw after reading the passage about The Sleep Workout?

Correct answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.
