Case Study 1: Tell Me About Blood 1. What is the significance of lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit?
A lower-than-normal hematocrit tells us that a person has anemia. A large amount of white blood cells due to cancer or some type of infection, vitamin or mineral deficiencies, or some type of blood loss. A bacterial infection will cause the hematocrit test show more white blood cells in the blood because it is trying to fight off the infection. 2. Compare the development of lymphocytes with the development of the other formed elements.
Lymphocytes are produced in the red bone marrow and some can be produced in lymphatic organs like the lymph nodes. B cell lymphocytes are in the red bone marrow where they live out their life cycle. T cell lymphocytes begin in the red bone marrow but later mature in the thymus. 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis?
Erythropoiesis produce red blood cells. The amount of oxygen being carried would affect the speed of erythropoiesis. 4. Explain what would happen if a person with type B blood were given a transfusion of type O blood.
A person that has type B blood can receive a transfusion from a person with type O blood because there are no antigens and the person with B blood will not have any antibodies that will attach the O blood. 5. During an anatomy and physiology exam you are asked to view white blood cells in prepared slides of standard human blood smears. Based on the observation below, what is the name and function of each WBC? A. WBC has a round nucleus surrounded by a blue halo of cytoplasm with no visible granules. Lymphocytes.

...Unit 1. Case Study 1. Tell Me About Blood Unit 1. Case Study 1. Tell Me About Blood 1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? (PAGE 618 619) First, hematocrit (HCT) is the percentage of blood made up of red blood cells. Usually measured by centrifuging a blood sample in a graduated tube and then reading the volume of red blood cells and dividing it by the total volume of blood in a sample. A significant drop in hematocrit is an indication of anemia (lower-than-normal number of red blood cells (Jenkins & Tortora, 2013). A bacterial infection would increase the production of white blood cells to fight off the infection. The hematocrit would have a thicker buffer layer (white blood cells) causing the red blood cell production to slightly decrease which would decrease the ratio of red blood cells to whole blood volume. 2. Compare the development of lymphocytes with the development of the other formed elements. (PAGES 629 631 632 769) Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid stem cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues,...

Unit 1 Case Study 1: Tell Me About Blood

...1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? The significance of lower than normal hematocrit is anemia. This can be caused by nutritional deficiency, loss of blood, bone marrow problems, or abnormal hematocrit. The effect of bacterial infection would cause a decrease in hematocrit. 2. Compare the development of lymphocytes with the development of the other formed elements. Leukocytes are produced or stored in many locations in the body, including the thymus, spleen, and bone marrow. The two kinds of lymphocytes are B lymphocytes and T lymphocytes. Lymphocytes start out in the bone marrow and either stay there to mature into B cells, or they leave for the thymus gland, where they mature into T cells. Other formed elements, such as blood is a mixture of plasma and other substances which are developed through red blood cells or erythrocytes. Thrombocytes or platelets are formed by fragmentation of megakaryocytes in the bone marrow. 3. What is Erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process of red blood cell formation or production which begins in the red bone marrow as a proerythroblast. It then divides several times until it reaches the end of development, ejects the nucleus, and becomes a reticulocyte. These develop into erythrocytes within one or two days after release from the bone marrow. Erythropoiesis slows down when there is a......

You may also click on the Audio: Thinking It Over if you prefer to listen to the case study. After reviewing the case study, answer the questions on below. Gayle and Patrick have been in a monogamous marriage for seven years. During a medical checkup, Gayle finds that she is HIV positive. Because she has not been sexually active outside her marriage and has never injected drugs, received a blood transfusion, or been hospitalized, she is quite certain that Patrick must have infected her. When she calls the local health clinic to discover if Patrick has been tested for HIV, they tell her that this information is confidential. She does not want to confront Patrick for fear that he may not be infected and she will have to explain her own infection.

She has to deal with two very large issues — she's infected with a life-threatening virus and she's living with doubt and fear about her partner. Since she's quite certain he transmitted the virus to her, he most likely is infected. How did he become infected? In what behavior did he participate that put him at risk, and eventually put her at risk as well? Why didn't he tell her about it? Why didn't he have himself tested to make sure he was HIV-free? Most people in such cases would be angry with their partners. But Gayle is......

Accepted 6 July, 2011 Few studies have focused on the processes in which patients reveal their HIV infection to others. This study sought to understand these processes. Thus, the research questions were: (a) What were their thoughts about the moment when patients learned that they were infected? (b) To whom and when did patients disclose that they were infected? (c) How did they disclose the information? (d) How much or what information did they disclose, and what were the reactions of those who were informed? (e) Why did they reveal the information? The descriptive study was done using a convenience sample of 45 patients with HIV/AIDS at a hospital clinic in northeastern Thailand. The results showed that 67% told a family member, usually their mother, within a day of being told about their HIV diagnosis from a medical staff. Most patients (65%) communicated the diagnosis face to face; only 4%......

All About Blood

...Unit 1 Case Study 1: Tell me about blood. 1. Lower than normal Hematocrit indicates Anemia. Hematocrit does not have enough Hemoglobin which is an oxygen carrying protein in red blood cells that results in having Iron, B12 and Folic Acid deficiencies. The main causes of developing Anemia include: medications and pregnancy, but the more serious causes include: kidney disease and cancer of the kidney, also leukemia and lymphoma. A bacterial infection on the Hematocrit can cause the white blood cell count to raise but lower Hematocrit. 2. Lymphocytes and other formed elements develop from Pluripotent cells. Pluripotent stem cells generate Myeloid and lymphoid stem cells. The Myeloid stem cells starts and completes development in red bone marrow and raises red blood cells, Platelets Eosinophils, Basophils, Neutrophils and Monocytes. The Lymphoid stem cells develop in red bone marrow but complete in the Lymphocytes tissue. 3. Erythropoiesis is the production of red blood cells or Erythrocytes.

Groups should consist of 3 to 4 individuals. Exceptions to this can be made for offcampus students if they can demonstrate difficulty in finding group members. You are free to form your own groups, whether through face-to-face contact or by using the ‘group formation’ forum on CloudDeakin. Ensure once your group is formed that you register it on CloudDeakin. You are required to finalise your group formation by the second week of trimester. GROUP WORK TIPS Your group will benefit from diversity. You are encouraged to form groups with a broad range of skills covering quantitative analysis, writing, editing skills and leadership skills. You should also try to form groups that cover diverse industry groups and cultural backgrounds. You should consider appointing a leader for the group. The role of the leader is to coordinate meetings and set deadlines. However, the group should still agree on decisions made by the leader and the group cannot expect the leader to bear responsibility for the group’s performance. At the initial stage, avoid assigning different tasks to each member.

Introduction

...Neeraj’s USMLE Step-2 CS Notes The Perfect “Encounter”: A Strategic Approach to Communication & Interpersonal skills The encounter in a USMLE CS examination is between a non-physician medical educator (SP: Standardized Patient) and an examinee, who may be a medical student or a physician. SPs are defined as "a simulated or real patient who has been taught to present a problem so accurately that the simulation cannot be detected by a skilled clinician.” (1) These SPs will seem like real patients to you and should be treated as such during the USMLE examination. With this in mind, it is important to remember that good communication and interpersonal skills are a top concern for every patient. If you have a pleasing personality, patiently hear all of their dilemmas and concerns, and have good communication skills, it will surely create and maintain long lasting and conducive relationships with your patients. Before we talk about strategies to delineate an ideal and perfect encounter with a SP, we should know a few facts about the examination. First, what is the purpose of the examination? It is very interesting that this examination is structured to test your clinical skill proficiency and not the diagnosis that you arrive at. Three components of the report score: One must pass all three components in a single test administration.
