Tell Me About Blood

1) A hematocrit is a blood test that measures the percentage of red blood cells in the total volume of whole blood. So a lower than normal hematocrit would mean that you have a lower than normal RBC’s (red blood cell) count for your age, sex, or condition. This signifies that you could have anemia, internal bleeding, or something is destroying your RBC’s, or your body is not producing them at an appropriate rate. The effect of a bacterial infection on a hematocrit would be that you would have a lower RBC count because you will have a higher WBC’s (white blood cell) count to combat the bacterial infection.

2) Leukocytes are produced and stored in different locations like the thymus, spleen, and bone marrow. There are two kinds of lymphocytes B lymphocytes and T lymphocytes (killer T cells). 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. Formed elements, such as blood is a mixture of plasma and other substances which are developed through erythrocytes. Platelets are formed by the fragmentation of megakaryocytes.

3) Erythropoiesis is the production of RBC’s. This begins in the red bone marrow and starts off as a proerythroblast. The proerythroblast then divides several times until it reaches the end of development and ejects the nucleus. After that it is called a reticulocyte. The reticulocyte develops into erythrocytes within one or two days after being release from the bone marrow. Erythropoiesis can slows down when there is enough oxygen-carrying RBC’s in the blood. It can speeds up when there is a mass distruction of RBCs such as trauma resulting in blood loss or if you donate whole blood.

4) If a person with type B blood were given a transfusion of type O blood, there would

Please alert me immediately if there is any deviation from normal range. Passive communication; here the problems don’t get solved and the delegator is avoided and ends up doing more work him or herself. Example of this communication style I have experienced in my work place is a case where my director asked the unit secretary Eva to type the paper for the vital signs of all the patients, make bed rosters, assignment sheets, discharge paper works, including diet sheet to give to the dietician before she leaves by the end of the day. The unit secretary typed and printed some of the papers, but could not finish on time. The director found out that the printed...

Case Study Gayle and Patrick

...Axia College Material Appendix G Case Study: Gayle and Patrick Read the following case study about Gayle and Patrick. 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. Audio: Thinking It Over This is a difficult situation for Gayle to find herself in. 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 holding...

Racism in the United States

...King Jr. come along and try to change the way things are by showing peace. Others like Malcolm X came along and tried to show that we were all equal by force. Regardless of which ever way was the correct way to go about things, we have gotten to a point where things are somewhat integrated. Although we are integrated and not dealing with the same problems there were 50 years ago, there are still those who do not like this new form of integration. In the state of Texas there are 62 documented hate groups. I can honestly say that the relatively high number didn’t surprise me. I actually wouldn’t have been surprised if the number was higher. Coming from California I heard often that Texas was different than California. In that people hadn’t came to accept integration as graciously as they had back home. They didn’t tell me this to scare me but more to prepare me for the new lifestyle I was about to embark in. I listened to them only to get this assignment and learn that California has more hate groups than Texas. One of the hate groups in Texas known as the ‘European-American Unity and Rights Organization’ was founded in 2000. The group was created by David Duke to help protect the rights and heritage of European Americans. Another group in Texas known as ‘Blood and Honour’ was formed in England back in the 1980s. They were known as a hate band, making hate music. This group rebelled against racial tolerance. These things going on in our world are simply just a part of...

...to teach overseas, you must receive vaccinations. You receive three vaccines and your life changes forever. Anxious about my trip to Cambodia and nervous about the three vaccines; I patiently wait for the nurse to call me back into an exam room. Sitting in the waiting room, I reflect on all that is to come. I will be getting vaccines so that I can teach for a month in Cambodia. When I come back I will be able to student teach and then graduate. Yes, I am so looking forward to graduation. Deep in my thoughts, I miss hearing the nurse call my name. The little old woman with a little too much perfume on nudges me and points to the door. Grabbing my coat, I whisper thank you before heading for the door. Inside the exam room, a nurse with shoulder length blond hair informs me that she is going to get the three shots and will be right back. A moment later, she returns with three needles and three alcohol swabs. Before administering each shot, she carefully cleans the intended injection site. She engages me in a conversation before she ever so cleverly sticks the needle into my upper arm injecting the serum. Placing a Band-Aid over each spot, she tells me to monitor the sites for possible swelling. I nod as I head out the door. Leaving the parking lot, my phone rings.

Solve a Problem

...or issue. If you encountered a specific problem or issue that you couldn’t resolve, you may need to ask someone with more experience or research the issue to reach an adequate solution. Producing ideas is the fourth and final stage. One must make a precise decision to determine which ideal concept they will take.  In this stage there lie two obstacles.  While trying to produce ideas one must fight the urge to limit your ideas.  The other obstacle is not settling on the first idea that comes to mind and to try harder to come up with something different. Some may think their first thought is also the best result, but you should challenge yourself to think past your first thought to chime into your creative nature. A personal challenge for me was going back to school. I had to think of all the different obstacles going back to school would pose on my normal day to day routine. Returning to school would interfere with my work schedule, not having time to cook dinner, and causing conflict with my spare time. Then, I realized that there are other ways to attend school and not just going to a standard university campus. I weighed my options by writing out all of the advantages and disadvantages of going to a school online and going to a campus. This included the different programs...

...Recruitment – Internal vs. External As the world today keeps changing and the economy struggles to maintain workforce; there needs to be a lot of things truly thought out before just posting a job and hiring a person. I know in the company that I work for in which I am the Director of HR/Payroll of a management group for eight places; one fireplace/landscape business, three donut shops, and.five assisted living facilities; we have general guidelines of posting jobs and process for recruiting but then there are many things that then must be specific to the industry of those business. I also did research and found that many have the same issues we do and what they feel is the key things to know for doing recruiting. In the management group we have developed a HR manual which has policy and procedures that must be followed for doing the steps for recruitment and the follow through to get the candidates hired. As I have attached a copy of the request for recruitment form, job requisition form and the job duties questionnaire and the job description form which are the tools we use to get positions approved and filled for the company in Appendix A. There is a step-by-step for doing the recruiting and where to post the jobs. We then follow this step up with the interview process and pre & post offer screening and then the orientation of new hire.

...they accomplish much of what they do. She helped me set aside some time and a place to present the information. We did find it a little difficult with the demands of the assignment and their time because they had other obligations but were helpful and made time for me. They gave me suggestions and ideas and talked to me about the best approach for teaching my community would be receptive to. A poster board was discussed and decided upon after discussing the other options. They explained that most people in this learning group would not sit through a powerpoint and enjoy talking and telling their stories so with a poster-board they can browse and talk and pick up little take-aways. The nurse did explain that my local hospital that most of our community uses does not offer any free services and most of the services come from an adjacent hospital who provide them with a lot of free services and resources. So to be aware they will not appreciate where I am coming from but will appreciate that I am trying to learn. I also consulted with a teacher friend of mine and asked for help with talking points as if talking to a grammar school crowd. I began with explaining what a stroke is and the differences in each as well as the causes. A stroke is similar to a heart attack except it occurs in the brain when the blood supply to that part of the brain is cut-off. This occurs when a blood clot blocks flow inside of a vessel or a blood vessel...

...Introduction Food Intake I was born to a father with the history of Diabetic mellitus and on my mother’s side; there is a history of High Blood Pressure. Although my father is not diabetic, my mother has been diagnosed with blood pressure. Blood pressure has been a steady disease in my household which has affected four out my five uncles. In 2010, after a seven year long battle with infertility, I was diagnosed with High Blood Pressure which I was given medication for and shortly thereafter, I had a son after my aggressive treatment. Ever since, I have always link most diseases with food intake and I strongly believe that my nutrition and my health work hand in hand. According to Grodner, Roth &Walkingshaw (2012), “The presence in the American diet of too much fat is directly related to several chronic diseases such as CAD and certain types of cancer. High-fat diets are indirectly related to type 2 diabetes mellitus and hypertension” (p.110). In order for me to remain in good health and to eliminate my disease, my daily food intake calorie should go to 2200 meal plan which includes breakfast, lunch, snack and dinner according to the super tracker web site . The purpose of this paper is to teach me how to eat healthy and to accomplish my goal of maintaining a healthy eating habit which includes an excellent food intake .

Evan 201 Reflection Paper

...thinking about the Work of the Cross. The Bible teaches Jesus died on the cross for man’s sins and to grant everlasting life to God’s followers with God in heaven. The sins of man are washed away with the blood of Christ and we receive God’s salvation and sanctification. When looking at the Work of the Cross, a Christian needs to look no further than John 3:16 (NRSV), which states, “For God so loved the world that he gave his only Son, so that everyone who believes in him may not perish but may have eternal life.” But this would be too simple of an answer for God’s intention for Christ on the cross and how Christ and the cross play a role in the salvation and sanctification of man. The next two verses, John 3:17-18, help explain it further, stating, “Indeed, God did not send the Son into the world to condemn the world, but in order that the world might be saved through him. / Those who believe in him are not condemned; but those who do not believe are condemned already, because they have not believed in the name of the only Son of God.” Christ dying on the cross was the Work of the Cross, but man must do some work themselves to gain the salvation and sanctification God has offered. Man must accept Christ as the Son of God and recognize Christ as the Messiah mentioned in earlier scripture. Without doing this, the Work of the Cross is in vain and man can be in for much suffering instead of eternal life with God. Part 2 Dr. Billy Graham (2000) lists Five Things Blood Brings as...
