HESI A2 Anatomy and Physiology Quizlet 2024

1. How does the integumentary system interact with the nervous system?

Correct answer: C

Rationale: Touch input via the integumentary system sends messages to the nervous system. The integumentary system, comprising the skin, hair, and nails, functions as a sensory organ and a protective barrier against external threats. Specialized receptors in the skin detect stimuli like pressure, temperature, and pain, transmitting signals to the nervous system for interpretation. This communication enables the perception of touch and is vital for sensory processes, showcasing the interconnectedness between the integumentary and nervous systems. Choices A, B, and D are incorrect because the integumentary system primarily interacts with the nervous system through sensory input and communication of stimuli, rather than heat removal, nutrient circulation, or affecting skin color and texture based on nervous system messages.

2. A cake recipe calls for 2½ cups of flour. How many cups are needed to make 6 cakes?

Correct answer: D

Rationale: To make one cake, you need 2½ cups of flour. To make 6 cakes, you would need 6 times the amount of flour for one cake, which is 2½ x 6 = 15 cups. Therefore, the correct answer is 15 cups. Choices A, B, and C are incorrect as they do not correctly calculate the total amount of flour needed for 6 cakes.

3. Which phrase correctly completes the sentence? 'During the fight, I was hit on ___.'

Correct answer: A

Rationale: The correct answer is 'A: Head.' The phrase 'on the head' is a prepositional phrase indicating where the person was hit. 'Head' is the correct noun to complete the sentence. Choices B, C, and D are incorrect because they either add unnecessary articles ('a' or 'the') or incorrectly use the preposition 'on' before 'head.' The correct structure is 'hit on the head,' without any additional articles.

4. What is the numerical value of the Roman numeral XVII?

Correct answer: B

Rationale: The Roman numeral XVII represents the number 17. In Roman numerals, X stands for 10 and V stands for 5. When V (5) is subtracted from X (10), it results in 5 being subtracted from 10, which equals 5. Adding this to V (5) gives the total value of XVII as 17. Choice A is incorrect because it is not the correct numerical value of XVII. Choice C and D are also incorrect as they do not correspond to the Roman numeral XVII.

5. What is the primary function of hemoglobin in red blood cells?

Correct answer: C

Rationale: The correct answer is C: 'To carry oxygen.' Hemoglobin in red blood cells binds to oxygen in the lungs and transports it to the tissues and organs throughout the body. This oxygen transport is crucial for cellular respiration and the overall functioning of the body. Choices A, B, and D are incorrect because hemoglobin's primary function is not to transport nutrients, fight infections, or produce energy in red blood cells.
