HESI A2 60 Questions with Verified Answers 2023 Which of these statements is true regarding the way light travels? A. Sound travels faster than light. B. The speed of light is always the same regardless of the medium through which it travels. C. Light travels as both a wave and a particle. D. Light can not travel through a vacuum. - CORRECT ANSWER C. Light travels as both a wave and a particle. Light is a curiosity in that it acts as both a wave and a particle. It only changes direction via reflection (bouncing off of something) or refraction (passing from one medium to another). In a vacuum, the speed of light is constant, but when passing through a medium that has an index of refraction different from a vacuum, light's speed slows. Which of these elements is liquid at room temperature?

A person with AB- blood should not receive blood from which other blood type? A. B- B. A- C. O- D. AB+ - CORRECT ANSWER D. AB+ Those with an AB- blood type should not receive blood from those with AB+ blood. Although both AB+ and AB- blood have A and B antigens, the person with AB- blood lacks a special protein, or "Rhesus" Factor (Rh), circulating in their blood. If they are given blood that has the Rh factor present, their body will make antibodies to this foreign substance and complications will occur. This is especially true in pregnancy situations where the mother is Rh- and the baby she is carrying is Rh+. Which blood type is considered the universal donor? A. O- B. O+ C. AB- D. AB+ - CORRECT ANSWER A. O- O- blood lacks both A and B antigens and the Rh factor, making it the only blood type that can donate to everyone. Note the correct use of the terms antibody and antigen: O- is the best donor because it does not have A, B or Rh antigens. AB+ is the universal receiver because it does not have A, B or Rh antibodies. What is the only artery in the body to carry oxygen-poor blood? A. renal artery B. interosseous artery C. vena cava D. pulmonary artery - CORRECT ANSWER D. pulmonary artery Most arteries in the body carry oxygen-rich blood away from the heart, but the pulmonary artery carries oxygen-poor blood from the right ventricle of the heart to the lungs. The vena cava would not be correct because it is not an artery, it is a vein and the question asks for an artery. Chocolate cysts of the ovaries are attributed to ____. A. menorrhagia B. ectopic pregnancy C. pelvic inflammatory disease D. endometriosis - CORRECT ANSWER D. endometriosis Endometriosis is a condition in which the tissue from the uterus (endometrium) grows in other parts of the body, such as the ovaries or bowel. If a woman has endometrial tissue in her ovary, the tissue bleeds and builds up over time, and as the blood ages it turns brown, hence the term "chocolate cyst." Which is not true of synovial joints? A. They are found in the intervertebral discs of the spinal column B. They have a fluid-filled capsule that surrounds their articulating surface C. They are the most common joint in the body D. They are the most moveable joint type in the body - CORRECT ANSWER A. They are found in the intervertebral discs of the spinal column Instead of a synovial joint, the intervertebral discs of the spinal column form a fibrocartilaginous joint, which allows slight movement of the vertebrae of the spine.

Positive feedback is a mechanism used by the body that results in amplification or enhancement of a signal that has already been activated. An example of this would be ____. A. the release of oxytocin to increase contractions during childbirth B. shivering to increase temperature C. slowing metabolism in response to starvation D. blood vessels regulating blood pressure - CORRECT ANSWER A. the release of oxytocin to increase contractions during childbirth Contractions in childbirth are considered a positive feedback loop because each contraction stimulates the brain to release more oxytocin, which in turn stimulates more contractions. When placed in a hypotonic solution, what will a cell do? A. shrink B. swell C. disintegrate D. remain the same - CORRECT ANSWER B. swell Water always moves from areas of higher concentration to lower concentration. A hypotonic solution contains less solutes and more water than the contents inside of the cell, so water will move from outside of the cell to inside, causing it to swell. Which is not an effect of photo-oxidation? A. loss of surface smoothness B. increase in brittleness C. increase in tensile strength D. discoloration - CORRECT ANSWER C. increase in tensile strength Photo-oxidation occurs when UV light and ozone break down the surface of polymers. The result is the material becoming more brittle and discolored and less strong and smooth. Using the Lewis-dot structure model, how many dots would carbon have? A. 6 B. 2 C. 4 D. 8 - CORRECT ANSWER C. 4 The number of dots in a Lewis-dot structure model corresponds to the number of valance electrons for that atom. Because carbon has four valance electrons, its Lewis-dot structure model would have 4 dots. Which of these would produce hydrogen ions in an aqueous solution and would turn a litmus test from blue to red? A. ammonia B. lye C. vinegar D. detergent - CORRECT ANSWER C. vinegar Blue litmus paper turns red in the presence of an acid. Ammonia, lye, and detergent are basic, so they would not give off hydrogen ions in an aqueous solution and when added to blue litmus paper the paper would remain blue.

A. 47 B. 32 C. 27 D. 72 - CORRECT ANSWER C. 27 In Roman numerals, an "X" represents the number 10, a "V" represents 5, and "I" is representative of the number 1. In this problem we have 2 X's, 1 V, and two II's, which means we have two 10's (20), one 5, and two 1's (2). Written mathematically, 20 + 5 + 2 = 27 What is (-5)2? A. 5 B. -25 C. 25 D. (-25)2 - CORRECT ANSWER C. 25 25 is correct. In this situation you address the parenthesis and then the exponent, and the negatives would cancel each other out for a positive answer. What is x2x4 ? A. x8 B. x6 C. 2(x8) D. 2x6 - CORRECT ANSWER B. x6 is correct because you add the exponents, 2+4 It is assumed in math that terms will be presented in their simplest form. This one is not, so you would add the exponents to simplify it: 2 + 4 = 6, so x2x4=x6. Lance makes $11.35 an hour and earns time and a half pay for every hour over 40. If Lance worked 47 hours this week, about how much will his paycheck be? Round to the hundredths place. A. $546.24 B. $454 C. $573.18 D. $521.37 - CORRECT ANSWER C. $573.18 $573.18 is correct because $11.35 an hour x 40 hours a week equals $454. Time and a half pay for Lance would be $17.025, and you figure that out by multiplying $11.35 an hour by 1.5. Then multiply $17.025 times 7 overtime hours to get $119.175. Lastly, add $454 and $119.175 and you will get $573.175. Rounded to the hundredth place would be $573.18. Dawn has a 20% off one shirt coupon at her favorite store. If she buys 3 shirts at $29.99 each and uses her coupon, how much will her total bill be? Round to the nearest hundredth. A. $89.97 B. $86.42 C. $83.97 D. $71.98 - CORRECT ANSWER C. $83.97 $83.97 is correct because $29.99 multiplied by 3 shirts is $89.97. To get 20% off of ONE shirt, $29.99 is multiplied by 0.20, which equals $5.998. You subtract $5.998 from $89.97 to get $83.972. Rounded to the nearest hundredth you would get the correct answer, $83.97. What is 0.85 x 0.65? A. 0.2552 B. 0.5252 C. 0.5525 D. 0.5520 - CORRECT ANSWER C. 0.5525 Multiply 0.85 by 0.65.

How would you write this as a mathematical expression? A. (5+1/2)N B. N/5⋅2 C. N/2+5 D. N+5/2 - CORRECT ANSWER C. N/2+5 First, we let N represent any number. We then express half of N as 1/2(N) or N/2. The phrase 5 more than indicates the mathematical expression 5+. Putting terms together, we get the correct answer. |7|+|−2| = ____ Note: This problem shows the number -2 within an absolute value sign, not the number -21. A. 9 B. 5 C. 0 D. 14 - CORRECT ANSWER A. 9 9 is the correct answer because the brackets around the numbers mean you are adding the absolute value of those numbers. The absolute value of a number is always positive, so: The absolute value of 7 is 7.The absolute value of -2 is 2.Therefore, the problem becomes: 7 + 2 = 9. Note: You will not do anything to signs outside the absolute value brackets, only those within them. (Absolute value brackets do not operate by the same rules as parentheses in math.)

What is her mass on Earth? A. 25 kg B. 0 kg C. 100 kg D. 50 kg - CORRECT ANSWER D. 50 kg While the woman's weight would change due to differences in gravitation force, her mass would remain the same no matter if she was on the Earth or moon. According to the accompanying text, what are the names of the three basic blood cells? A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice. A CBC searches for all the cells that exist in the blood, which are divided into three basic types: white blood cells (leukocytes), platelets, and red blood cells (erythrocytes). All of these blood cells are produced in the bone marrow and correspond to a specific exam, integrated in the CBC: erythrogram, leukogram, and thrombogram. The erythrogram studies red blood cells. Among other tests, it includes a red blood cell count, a hematocrit, and hemoglobin. When these levels are low, the patient may be suffering from anemia, which can be caused by anything from heavy menstrual bleeding to Addison's disease. A diagnosis of polycythemia may be made if the number of red blood cells is increased. The leukogram is the test that eva - CORRECT ANSWER B. leukocytes, platelets, and erythrocytes The three basic blood cells are white blood cells (also called leukocytes), platelets, and red blood cells (also called erythrocytes). Referring to the attached passage, what is the name of the disease characterized by a high number of red blood cells? A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice. A CBC searches for all the cells that exist in the blood, which are divided into three basic types: white blood cells (leukocytes), platelets, and red blood cells (erythrocytes). All of these blood cells are produced in the bone marrow and correspond to a specific exam, integrated in the CBC: erythrogram, leukogram, and thrombogram. The erythrogram studies red blood cells. Among other tests, it includes a red blood cell count, a hematocrit, and hemoglobin. When these levels are low, the patient may be suffering from anemia, which can be caused by anything from heavy menstrual bleeding to Addison's disease. A diagnosis of polycythemia may be made if the number of red blood cells is increased. The - CORRECT ANSWER A. polycythemia The text states that a person may be diagnosed with polycythemia if his or her red blood cells counts are increased. Which statement can correctly be inferred from the accompanying passage? A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice. A CBC searches for all the cells that exist in the blood, which are divided into three basic types: white blood cells (leukocytes), platelets, and red blood cells (erythrocytes).

When these levels are low, the patient may be suffering from anemia, which can be caused by anything from heavy menstrual bleeding to Addison's disease. A diagnosis of polycythemia may be made if the number of red blood cells is increased. The leukogram is the test that evaluates the num - CORRECT ANSWER D. A CBC gives a more complete evaluation of a patient's blood than a leukogram. While this is not explicitly stated in the passage, two statements provide evidence of the truth of this statement: "A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice." "...integrated in the CBC: erythrogram, leukogram, and thrombogram." Since the leukogram is only one part of the CBC and the CBC is defined as one of most useful tests, one may infer that the CBC would provide a more complete picture than the leukogram alone. The other answer choices cannot be inferred from the passage. Pregnancy is only one possible cause of low platelets. No part of the test is referred to as being "more informative" than another; they can all detect the possibility of important medical conditions. Finally, although the CBC is deemed highly useful, there is no evidence in this passage that it would be recommended for every single patient exam. When you infer something from a passage, you have to be able to point to specific evidence that supports your inference. According to the attached text, why is it important to be tested for allergies if they are suspected? An allergy is defined as an "immunological hypersensitivity to a specific external stimulus" or, simply put, an exaggerated response of the immune system to a substance that is foreign to the body. Patients with allergies are called "atopic" or, more popularly, "allergic". The diagnosis of an allergy is mainly clinical and it can be aided by skin allergy tests and laboratory examinations. Skin allergy tests are fast, practical, and can be done in an allergy and immunology provider's office. While skin tests are generally sufficient to confirm a diagnosis, doctors may also request complementary laboratory studies for further confirmation. These blood tests may diagnose an increase in white blood cells or antibodies for common allergy triggers, such as pet dander, grasses, and molds. Blood tests may help confirm or exc - CORRECT ANSWER D. all of these The second paragraph of the text mentions all of these as potential benefits of allergy testing. (Since the article is about allergies and testing for them, you can assume that the medications mentioned here are ones for allergies.)

Blood tests may help confirm or exclude the possibility of an all - CORRECT ANSWER A. Skin tests are the most accurate way to confirm an allergy test. While the text mentions that skin tests are "generally sufficient" to confirm an allergy, further detailed testing is sometimes needed for confirmation. The other answer choices are not specifically stated in the passage, but you can infer them from information that is given by the author. What is the main conclusion you can draw from the accompanying text? A quantitative descriptive study focused on the attitudes of nurses towards chronic pain found in the cancer patient population. The study sample was composed of 93 nurses from three hospitals with an average age of 30.54 years. Of these, 45.2% had a bachelor's degree. Throughout their professional careers, 91.4% of the nurses said they had acquired training in the assessment and treatment of pain. A small percentage, 18.3%, acquired this training through postgraduate studies or equivalent. However, 76.5% of these nurses found their training insufficient and experienced difficulties in the assessment of chronic pain in cancer patients. The study concluded that many nurses have little knowledge about cancer-related pain in the areas of pain assessment, pain management, psychological pain, spiritual pain, and the side effects of analgesic therapy. The - CORRECT ANSWER B. Nurses need more training in order to take care of patients in pain. The final sentence of the passage concludes that, "The results suggest the need for more training [of nurses] in the area of pain and pain assessment in this population." Which of these is not mentioned in the accompanying text? A quantitative descriptive study focused on the attitudes of nurses towards chronic pain found in the cancer patient population. The study sample was composed of 93 nurses from three hospitals with an average age of 30.54 years. Of these, 45.2% had a bachelor's degree.

The study concluded that many nurses have little knowledge about cancer-related pain in the areas of pain assessment, pain management, psychological pain, spiritual pain, and the side effects of analgesic therapy. The results su - CORRECT ANSWER A. This study was influenced by independent variables. Independent variables were not mentioned in this passage. The idea that nurses need more training in the area of pain and the statistics about the number of nurses who acquired their training through postgraduate studies and the number of nurses in the study who have a bachelor's degree were explicitly stated. What is the primary purpose of the accompanying article on smallpox? Smallpox is one of the most deadly and dangerous diseases affecting the human population across the world. The first recorded epidemic was in 1350 BC during the Egyptian-Hittite war, and it was quite prevalent in the late 1800's through a large part of the 1900's. Approximately five hundred million people were infected with the disease prior to its eradication in the 1970's, with the last case being in Somalia in 1977. Symptoms of infection included excessive bleeding, high fever, delirium, vomiting, and a raised pink rash. Most cases of smallpox ended in death and survivors were often seriously maimed by pock marks, blindness, or infertility. The pain and suffering remained for a lifetime after the disease was gone. There is no known cure for smallpox, only preventative vaccinations. Because smallpox was wiped out in 1970′s, the World Health Orga - CORRECT ANSWER D. to examine the issue of what to do with the remaining smallpox vaccines The issue of what to do with the remaining smallpox vaccines is brought up several times in the article. In the second paragraph, it states, "Because the disease is considered eradicated, the issue of what to do with the remaining government-held vaccines has been an issue of debate." In the conclusion, the article again mentions, "The question remains: do we run the risk of bioterrorism by continuing to store several hundred smallpox vaccinations or do we destroy the vaccine and pray that there is no outbreak of the deadly virus?" The other options are either not mentioned or are untrue. Which of these is the best definition of the word distended?
