Anatomy and Physiology Hesi A2 Practice Test

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

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.

2. If a runner runs 5 miles in 45 minutes, what is their average speed in miles per hour?

Correct answer: A

Rationale: To find the average speed, first, convert 45 minutes to hours (45/60 = 0.75 hours). Then, divide the distance by the time: 5 miles รท 0.75 hours = 6.67 mph. Choice A is correct because it accurately calculates the average speed based on the distance covered and time taken. Choice B is incorrect as it does not consider the time taken to cover the distance. Choice C is incorrect as it is higher than the calculated speed. Choice D is incorrect as it is higher and does not match the calculated average speed.

3. Fluids can be categorized based on their shear stress-strain rate relationship. An ideal fluid exhibits:

Correct answer: A

Rationale: An ideal fluid, often referred to as an inviscid fluid, is a theoretical concept used in fluid mechanics to simplify calculations. It is characterized by having zero shear stress at any strain rate. In reality, such fluids do not exist, but they serve as a useful starting point for understanding fluid behavior in idealized situations. Choice B is incorrect because a linear relationship between shear stress and strain rate defines a Newtonian fluid, not an ideal fluid. Choice C is incorrect because a non-linear relationship between shear stress and strain rate characterizes Non-Newtonian fluids, not ideal fluids. Choice D is incorrect because the high dependence of viscosity on temperature is a characteristic seen in real fluids and does not define an ideal fluid.

4. In a local baseball team, 4 players, which represent 5% of the team, have long hair, and the rest have short hair. How many short-haired players are there on the team?

Correct answer: C

Rationale: Given that 4 players represent 5% of the team, let's denote the total number of players as x. The equation to represent this situation is 0.05x = 4. Solving for x, we get x = 80, which is the total number of players on the team. Since 4 players have long hair, the remaining players have short hair, which is 80 - 4 = 76. Therefore, there are 76 short-haired players on the team. Choices A, B, and D are incorrect as they do not consider the total number of players correctly, leading to inaccurate calculations.

5. Identify the overall tone of the essay about Aromatherapy.

Correct answer: B

Rationale: The tone of the essay is uncertain, as the author questions the validity of aromatherapy based on the study's results. The phrasing "does not necessarily prove that aromatherapy is worthless" indicates a hesitance to fully endorse or dismiss its value. This ambiguity throughout the passage reinforces the uncertain tone, aligning it with choice B.
