Reading Comprehension HESI A2 Practice Test

1. Which of the following is not mentioned as being important for seniors?

A. Vitamin B12
B. Calcium
C. Nitrates
D. Exercise

Correct answer: C

Rationale: The passage lists important nutrients for seniors, including fiber, calcium, vitamin D, and B12, while exercise is also discussed as crucial for health. However, nitrates are not mentioned at all, making option C correct since it stands out as the only nutrient not discussed in the context of seniors’ health

2. A nurse needs to dilute 2 milliliters of a concentrated medication with 8 milliliters of sterile water. What is the final concentration of the solution in percent?

A. 16.67%
B. 20%
C. 25%
D. 50%

Correct answer: B

Rationale: To find the final concentration, first, calculate the total volume of the solution (2 ml + 8 ml = 10 ml). Then, determine the concentration by dividing the volume of the concentrated medication by the total volume and multiplying by 100%: (2 ml / 10 ml) * 100% = 20%. Therefore, the correct answer is B. Choice A (16.67%) is incorrect as it does not represent the correct calculation. Choices C (25%) and D (50%) are both incorrect as they do not reflect the accurate concentration resulting from the dilution process.

3. Which of the following structures is found in the upper respiratory system alongside the Pharynx?

A. Larynx
B. Trachea
C. Pharynx
D. Bronchi

Correct answer: A

Rationale: The correct answer is 'Larynx.' The larynx is indeed located in the upper respiratory system alongside the pharynx. Positioned below the pharynx and above the trachea, the larynx is crucial for breathing and sound production. The trachea and bronchi are part of the lower respiratory system and are situated below the larynx, making them incorrect choices in this context.

4. Which gland is responsible for producing adrenaline?

A. Thyroid gland
B. Adrenal gland
C. Pituitary gland
D. Pineal gland

Correct answer: B

Rationale: The correct answer is the Adrenal gland. The Adrenal glands, situated on top of the kidneys, are responsible for producing adrenaline. Adrenaline is a hormone that prepares the body for the fight-or-flight response during stress. Choice A, the Thyroid gland, is responsible for producing hormones that regulate metabolism, not adrenaline. Choice C, the Pituitary gland, regulates many of the body's functions by producing various hormones but is not responsible for adrenaline production. Choice D, the Pineal gland, produces melatonin, a hormone that regulates sleep-wake cycles, and is not responsible for adrenaline production.

5. The development of the disease was 'insidious'. What does insidious mean in this context?

A. Gradual
B. Momentous
C. Sudden
D. Innocuous

Correct answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.
