Read passage 3 and answer the questions following the passage.
1 Erythrocytes are red blood cells. 2 They make up the majority of the cells found in human blood. 3 The volume in a cubic milliliter of blood contains more than four million of them and only thousands of the
other blood cells.

4 The function of red blood cells is essential to life. 5 Erythrocytes travel continuously through the body's veins and capillaries. 6 As they circulate, they carry oxygen and carbon dioxide between the lungs and the other living cells. 7 They move oxygen to cells and carbon dioxide away from them.

8 The constant exchange of gases is vital since it keeps the body tissues alive and functioning,
An essential pigment in erythrocytes enables oxygen to combine with them. 10 This pigment,
hemoglobin, also produces the red color of blood. 11 The amount of hemoglobin in red blood cells influence the amount of oxygen they carry. 12 Abnormal levels of hemoglobin affect 'oxygen delivery to the tissues, which hinders the body's functions.

13 The type of hemoglobin in red blood cells also affect their function. 14 For example, sickle cell disease produces high levels of an abnormal hemoglobin. 15 This genetic malady prevents erythrocytes from freely moving through veins and capillaries and carrying oxygen effectively,
16 As cells, erythrocytes are unique. 17 They both generate and develop in the bone marrow along with other cell, but they have no nucleus. 18 Other blood cells include this dense internal component that contains genetic material. 19 Erythrocytes lose their nucleus as they mature, before the marrow releases them to circulate through the bloodstream.

During the last seven months of, 'gestation, developing babies' marrow produces fetal hemoglobin. This hemoglobin is called hemoglobin F. Hemoglobin A, adult hemoglobin, starts to replace hemoglobin F a few weeks before birth.

Read Passage 5 and answer the questions following the passage.

1 Pharmacology is the study of drugs and how they affect living things. 2 It is the science of substances that have medicinal properties. 3 These substances are called pharmaceuticals or medications.

4 Nursing pharmacology studies the type of drugs called medications. 5 It explores the composition and characteristics of medications. 6 It describes how they act and interact with humans and their physiologic processes.

7 It focuses on therapeutic medications-substances or agents that treat diseases or medical conditions. 8 It also studies how they can be toxic to life processes.

9 Nursing pharmacology combines the sciences of nursing, chemistry, biology, medicine, and physiology. 10 It joins these with statistics, mathematics, business, education and other fields.

11 Nursing pharmacology includes several subtypes: Clinical pharmacology studies the medical effects of medications Neuropharmacology studies the effects of mediations on the nervous system; Psychopharmacology studies the effects of medications on behavior

12 Nurses know about pharmacology regulation, which requires that all medications must be safe. 13 They know that extensive studies must prove that medications do not harm people. 14 They understand that regulations also require that medications must be effective-thorough testing must prove that they treat the diseases they target. 15 They know that medications are tested for effectiveness before they treat disease.

16 Nursing pharmacology is an ever-changing and growing science. 17 Nurses continually study it, to learn about new medications and new types of medications. 18 They know about commonly used medications and how they meet specific treatment needs.

1Chemistry is the science that studies matter and change. 2It works with substances and their properties. 3It examines elements, atoms, molecules, compounds, and their parts. 4It studies solids, liquids, gases, compounds, and elements.

5It investigates steady states, changing states, and ways things interact. 6It uses experiments to discover what happens when substances combine or change.

7Chemistry examines matter and energy. 8It describes their properties, and it works with them in a variety of ways. 9It uses tests to determine what happens as matter and energy change. 101t also investigates how temperature, pressure, and other conditions affect matter.

11The science of chemistry includes many types. 12Several of these types are organic chemistry and inorganic chemistry, and physical chemistry, biochemistry, and analytical chemistry.

13Organic chemistry studies matter that contains carbon, a main component of all living things. 14Inorganic chemistry explores matter that has no carbon, including minerals and other non-living materials. 15It studies metals in living systems, atoms and radioactive substances, and the chemical nature of the Earth and the other planets

16Physical chemistry develops theories to describe ways substances behave. 17Biochemistry studies living species and what they are made of. 18Analytical chemistry separates matter into its basic parts and it identifies these parts.

19All types of chemistry work together to describe the material and energy that makes up our world. 20 They use experiments and theories to explain matter and how it changes

Read passage 2 and answers the questions following the passage.

1 Falls frequently cause accidents, serious injuries, and accidental death in the elderly. 2 Falling puts older people at a great personal risk that cannot be ignored. 3 Understanding the risks of falls and taking precautions against them can protect senior citizens from this problem.

4 Everyone is at risk for falling, regardless of age group, strength, or health status. 5 However, young children and elderly adults seem to fall most frequently, and the elderly are at the greatest rick of, falling.

6 Children's bodies are typically more resilient and resistant to injury from falls. 7 Always haphazardly on the move, toddlers typically bounce back after they topple.

8 They quickly pull themselves, up and waddle off uninjured, only to harmlessly tumble down again a few steps later. 9 In contrast, many elderly people are injured when they fall. 10 Their bodies are fragile and susceptible to injury. 11 They are frail and easily hurt. 12 They rarely "bounce back" after they topple. 13Consequently, they usually avoid living alone and risking falling with no one there to help. 14 AS people age, their eyesight, hearing, and reflexes often diminish, increasing their likelihood of falling. 15 Sometimes they do not see or hear things that might warn them of danger. 16 Frequently their adaptation to sudden changes in position diminishes.

17 Chronic illness also reduces older people's strength and balance, increasing the likelihood of falling. 18 Side effects of medications they take sometimes cause light-headedness and loss of balance.

19 Several factors often work together to make the elderly prone to falls. 20 When they do not have or use the lighting needed to see clearly as they walk in their surroundings. 21 Age and wear and tear on the body sometimes make their legs unsteady and their ankles weak. 22 Also, their reflexes typically slow down as they age.

1Transfusion of a persons' own blood is called autologous transfusion. 2It's different from transfusion of blood given by others homologous transfusion, and transfusion of blood given by friends or family-directed donation.

3The public's growing interest in AIDS increases its interest in blood transfusion. 4It also leads some people to worry about receiving donated blood. 5Public concern about spreading disease through blood transfusion has increased the number of autologous transfusions. 6This trend promotes research and progress in autologous transfusion

7Now many people believe that a person's own blood is the safest blood to receive

8Advances in medicine continues to reduce the risk of transmitting viruses, such as human immunodeficiency virus (HIV), through blood. 9Research steadily finds new ways to test blood for disease, and blood donated by volunteers is becoming a safer product.

10Medical professionals often suggest autologous transfusion. 11They want the people to know that it is a choice they might have when they need blood. 12They encourage people to receive their own blood because it reduces possible negative effects of transfusion, 13 Receiving one's own blood ensures that the blood is compatible.

14 Transfusion of autologous blood avoids many types of transfusion reactions. 15Transfusion of directed donation blood does not prevent these reactions. 16 However, it’s difficult to change public Perceptions about this. 17 Many people still believe that receiving blood donated by family and friends prevents disease transmission. 18 Sometimes people choose not to donate blood.

19 Autologous transfusion is not always the best medical treatment. 20 Sometimes blood loss does not require transfusion. 21 It is impractical for large numbers of people to donate 'blood for the possibility of receiving it. 22 Also, some people who want to donate blood do not meet medical guidelines for donation.
