HESI A2 Anatomy and Physiology Practice Exam Questions
Question 1 of 5
Which of these can provide significant protein to a person on a vegan diet?
Correct Answer: C
Rationale: The correct answer is C: Tofu. Tofu, made from soybeans, is a complete protein source, providing all essential amino acids needed by the body. It is a significant protein source for individuals on a vegan diet. Eggs (A) and fish (B) are animal products and not suitable for a vegan diet. Leafy greens (D) are not a significant source of protein compared to tofu and may not provide enough protein for a person following a vegan diet.
Question 2 of 5
What is the average normal body temperature in degrees Celsius?
Correct Answer: D
Rationale: Failed to generate a rationale after 5 retries.
Question 3 of 5
What structures are likely torn in a rotator cuff tear?
Correct Answer: A
Rationale: The correct answer is A: Tendon and possibly ligament. In a rotator cuff tear, the structures that are typically torn are the tendons of the rotator cuff muscles, particularly the supraspinatus tendon. The rotator cuff is composed of muscles and tendons, not ligaments. While it is possible for some ligaments to be involved in severe cases, the primary structures affected are the tendons. Choice B is incorrect because muscles are not typically torn in a rotator cuff tear. Choice C is incorrect as ligaments are not the primary structures involved in a rotator cuff tear. Choice D is incorrect as it suggests that only the tendons are affected, whereas the tear commonly involves both tendons and possibly ligaments.
Question 4 of 5
The sebaceous glands are part of which system?
Correct Answer: D
Rationale: The correct answer is D, Integumentary system. Sebaceous glands are located in the skin, which is part of the integumentary system. These glands secrete sebum to lubricate and protect the skin. The endocrine system (choice A) regulates hormones, not sebum production. The digestive system (choice B) processes food, not related to sebaceous glands. The respiratory system (choice C) is responsible for gas exchange, not sebum secretion. Therefore, the integumentary system is the correct choice.
Question 5 of 5
Which of the following is true about skeletal muscle?
Correct Answer: B
Rationale: The correct answer is B because skeletal muscle attaches to bones by tendons, allowing for movement of the body. Tendons are tough connective tissues that anchor muscles to bones. This attachment enables the contraction of skeletal muscles to produce movement at the joints. Choices A, C, and D are incorrect. Skeletal muscle typically makes up around 40-50% of the body's weight, muscle contraction plays a role in temperature regulation through shivering, and skeletal muscles can contract even at rest due to maintaining posture or supporting the body.
