lOMoAR cPSD| 19500986 1 | P a g e HESI A2 V2 ENTRANCE EXAM LATEST EDITION 2023 QUESTIONS AND ANSWERS GRAMMAR, VOCABULARY, READING COMPREHENSION, MATH, A&P, BIOLOGY AND CHEMISTRY (DETAILED ANSWERS) S ECTION I - R EADING C OMPREHENSION. Directions: The following questions are based on a number of reading passages. Each passage is followed by a s eries of questions. Read each passage carefully, and then answer the questions based on it. You may reread the passage as often as you wish. When you have finished answering the questions based on one passage, go right on to the next passage. Choose the be st answer based on the information given and implied. Questions 1 3 4 refer to the following passage. Passage 1 - Infectious Disease An infectious disease is a clinically evident illness resulting from the presence of pathogenic agents, such as viruses, bacteria, fungi, protozoa, multi - cellular parasites, and unusual protein known as prions. Infectious pathologies are also called communicable diseases or transmissib diseases, due to their potential of transmission from one person or species to another by a replicating agent (as opposed to a toxin). Transmission of an infectious disease can occur in many different ways. Physical contact, liquids, food, body fluids, contaminated objects, and airborne inhalation can all tr ansmit infectin agents. Transmissible diseases that occur through contact with an ill person, or objects touched by them, are especially infective, and are sometimes referred to as contagious diseases. Communicable diseases that require a more specializ ed route of infection, such as through blood or needle transmission, or sexual transmission, are usually not regarded as contagious. The term infectivity describes the ability of an organism to enter, survive and multiply in the host, while the infectious ness of a disease indicates the comparative ease with which the disease is transmitted. An infection however, is not synonymous with an infectious disease, as an infection may not cause important clinical symptoms. 1 1. What can we infer from the first paragraph in this passage? a. Sickness from a toxin can be easily transmitted from one person to another. b. Sickness from an infectious disease can be easily transmitted from one person to another. c. Few sicknesses are transmitted from one person to anot her.

lOMoAR cPSD| 19500986 d. Infectious diseases are easily treated. 2. What are two other names for infections9 pathologies? a. Communicable diseases or transmissible diseases b. Communicable diseases or terminal diseases c. Transmissible diseases or preventable diseases d. Communicative diseases or unstable diseases 3. What does infectivity describe? a. The inability of an organism to multiply in the host b. The inability of an organism to reproduce c. The ability of an organism to enter, survive and multiply in the host d. The abi lity of an organism to reproduce in the host 4. How do we know an infection is not synonymous with an infectious disease? a. Because an infectious disease destroys infections with enough time. b. Because an infection may not cause important clinical symptoms or impair host function. c. We do not. The two are synonymous. d. Because an infection is too fatal to be an infectious disease. Questions 5 3 8 refer to the following passage. Passage 2 - Viruses A virus (from the Latin virus meaning toxin or poison) is a small infectious agent that can replicate only inside the living cells of other organisms. Most viruses are too small to be seen directly with a microscope. Viruses infect all types of organisms, from animals and plants to bacteria and single - celled organisms. Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, all n h u r a s y v l a e b.c a o m p - T r h o e t M e a r i k n et p c l a o c e a t o t B t u h y a a n t d p S e r l l o y o t u e r c S t t u s d y t M h a e te r s i a e l genes, and some have an envelope of fat that surrounds them when they are outside a cell. (Viroids do not have a protei coat and prions contain no RNA or DNA.) Viruses vary from simple to very complex structures Most viruses are about one hundred times smaller than an average bacterium. The origins of viruses in the evolutionary history of life are unclear: some may have evolved from plasmids4 pieces of DNA that can move between cells4while others may have evolved from bacteria. Viruses spread in many ways; plant viruses are often transmitted from plant to plant by insect that feed on sap, such as aphids, while animal viruses can be carried by blood - sucking insects These disease - bearing organisms are known as vectors. Influenza viruses are spread by coughing and sneezing. HIV is one of several viruses transmitted through sexual contact and b exposure to infected blood. Viruses can infect only a limited range of

What is one common virus spread by coughing and sneezing? a. AIDS b. Influenza c. Herpes d. Tuberculosis Questions 9 3 11 refer to the following passage. Passage 3 3 Clouds The first stage of a thunderstorm is the cumulus stage, or developing stage. In this stage, masses of moisture are lifted upwards into the atmosphere. The trigger for this lift can be insulation heating the ground producing thermals, areas where two winds converge, forcing air upwards, or where winds blo n u w rsyl o a b v . c e o m r - t T e h e rr M a a r i k n et p o l a f ce i t n o c B u r y e a a n d s S i e n l l g yo u e r l S e t u v d y a M ti a o t e n ri a . l Moisture in the air rapidly cools into liquid drops of water, which appears as cumulus clouds. As the water vapor condenses into liquid, latent heat is released which warms the air, causing to become less dense than the surrounding dry air. The warm air rises in an updraft through th process of convection (hence the term convective precipitation). This cre ates a low - pressure zone beneath the forming thunderstorm. In a typical thunderstorm,
