HESI A2 Anatomy and Physiology Practice Exam

1. How many bones are in the human foot?

Correct answer: C

Rationale: The correct answer is C: 26. The human foot consists of 26 bones, including tarsal bones, metatarsal bones, and phalanges. These bones collaborate to offer support, flexibility, and stability for various activities like standing, walking, and running. Choice A (6) is incorrect as it is too low for the number of bones in the human foot. Choice B (16) is incorrect as it underestimates the actual number of bones in the foot. Choice D (36) is incorrect as it overestimates the number of bones in the human foot.

2. Which mineral is important for the formation of red blood cells?

Correct answer: D

Rationale: Copper is crucial for the formation of red blood cells as it is a component of enzymes involved in the production of hemoglobin. Hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body, requires copper for its synthesis. A deficiency in copper can result in anemia due to insufficient production of red blood cells. Selenium, calcium, and magnesium do not play a direct role in red blood cell formation, making them incorrect choices for this question.

3. Which of the following statements is anatomically correct?

Correct answer: C

Rationale: The term 'proximal' refers to a body part being closer to the center of the body or a point of reference. In this case, the hip is closer to the center of the body compared to the knee, which makes the statement anatomically correct. Choice A is incorrect as the knee is proximal to the ankle. Choice B is incorrect as the heart is superior to the diaphragm. Choice D is incorrect as the elbow is proximal to the wrist.

4. Which enzyme functions to break down lactose, a specific sugar found in milk and dairy products?

Correct answer: D

Rationale: Lactase is the enzyme responsible for breaking down lactose, a sugar present in milk and dairy products. When lactase breaks down lactose, it splits it into two simpler sugars, glucose, and galactose, which can then be absorbed and used by the body. Catalase is involved in breaking down hydrogen peroxide into water and oxygen. Lipase breaks down fats into fatty acids and glycerol. Protease breaks down proteins into amino acids. Therefore, choices A, B, and C are incorrect for the specific breakdown of lactose.

5. How many different types of tissues are there in the human body?

Correct answer: A

Rationale: There are four major types of tissues in the human body: epithelial, connective, muscle, and nervous tissues. Epithelial tissue covers body surfaces, connective tissue supports and binds other tissues together, muscle tissue enables movement, and nervous tissue allows for communication between different parts of the body. Choices B, C, and D are incorrect because the human body has four main types of tissues, not six, eight, or ten.
