HESI A2 Practice Vocabulary

1. If a patient has SALLOW skin, what is true?

Correct answer: A

Rationale: Sallow skin is a term used to describe skin that appears yellowish in color. This discoloration can be due to various factors, such as an underlying health condition, poor circulation, or certain medications. Observing sallow skin can be an important clinical indicator that prompts further investigation into the patient's overall health status. Choice B, blue tint, is incorrect as sallow skin is not associated with a blue color. Choice C, red tint, and Choice D, green tint, are also incorrect as sallow skin specifically refers to a yellowish complexion, not red or green.

2. How many pounds are in 80 ounces?

Correct answer: A

Rationale: To convert ounces to pounds, you need to know that there are 16 ounces in a pound. Therefore, to find how many pounds are in 80 ounces, you divide 80 by 16, which equals 5 pounds. Thus, the correct answer is 5 pounds. Choice B, 6 pounds, is incorrect because it doesn't accurately reflect the conversion from ounces to pounds. Choice C, 4 pounds, and Choice D, 3 pounds, are also incorrect as they do not align with the correct conversion factor of 16 ounces to 1 pound.

3. How do the muscular and skeletal systems collaborate to facilitate movement?

Correct answer: A

Rationale: The muscular system and the skeletal system collaborate to facilitate movement. Muscles are connected to bones through tendons and contract to generate movement at the joints. When muscles contract, they exert force on the bones, resulting in actions like bending the arm or leg. This coordinated effort between muscles and bones is crucial for various activities such as walking, running, and grasping objects. Choices B, C, and D are incorrect because they do not accurately describe the interaction between the muscular and skeletal systems. The skeletal system's primary role is to provide structural support and protect internal organs, while cardiac muscles are responsible for heart function and not bone strength. Smooth muscles are found in internal organs and are not involved in leaching excess minerals from bones.

4. The car that he had seen at the Ford dealer was the one that he finally decided to _____.

Correct answer: A

Rationale: The correct answer is 'buy' because it is the appropriate verb for purchasing a car. In this context, the person saw a car at the Ford dealer and decided to buy it, indicating ownership. Choices B, C, and D are incorrect because 'rent,' 'lease,' and 'sell' do not fit the context of deciding to acquire a car for ownership. Renting and leasing involve temporary possession, while selling involves transferring ownership to another party.

5. Which type of blood cell is primarily responsible for fighting infections?

Correct answer: B

Rationale: White blood cells, also known as leukocytes, play a crucial role in the immune system by primarily combating infections. These cells can identify and destroy pathogens, such as bacteria and viruses, helping the body defend against illnesses and maintain overall health. Red blood cells are responsible for oxygen transport, platelets aid in blood clotting, and plasma carries various components throughout the circulatory system, but none of these functions involve fighting infections like white blood cells do.
