Reading Material

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 evaluates the number of white cells present in the blood, which should vary between 4,000 and 10,000 cells per cubic millimeter in most adults. High values of white blood cells are seen with infection or severe emotional/physical stress, while AIDS and chemotherapy are two causes for low values.

The thrombogram is the analysis of platelets, the cells responsible for coagulation. The main function of platelets is to help stop bleeding by helping form a clot. They do this by secreting proteins from their surface that allow them to stick to vessels and each other. Low values of platelets are seen with pregnancy or an enlarged spleen, whereas high values are seen with cancers or iron deficiency.

Which statement can correctly be inferred from the accompanying passage?

A. A CBC gives a more complete evaluation of a patient's blood than a leukogram.

B. The test of red blood cells is more informative than the tests of white blood cells and platelets.

C. An elevated level of platelets is a confirmation of pregnancy in the patient.

D. A CBC should be part of every physical exam because it tells so much about the patient's blood.

Read the following passage and answer the question.

WHAT IS EQUAL EMPLOYMENT OPPORTUNITY?

SmithCo, Inc. Associate Manual

Commitment to Equal Employment Opportunity

Equal Employment Opportunity Equal Opportunity is the expressed policy of SmithCo. Our policy is to select the best-qualified person for each position in the organization and to conduct all business relationships without prejudice. SmithCo is committed to the principles of equal employment opportunity for all employees and applicants for employment. Advancement opportunities and employment decisions will be made without regard to race, creed, color, religion, sex, national origin, ancestry, age, physical or mental handicap, veteran or military status, or any other characteristic protected under federal, state, or local law. Managers are expected to seek out a diverse pool of candidates for consideration when making hiring decisions. SmithCo also develops an annual Affirmative Action program, which is a federal requirement due to our status as a government contractor. The leadership team plays an active role in demonstrating SmithCo's commitment by providing equal employment opportunities at all levels of employment. Managers and employees are advised to meet with the HR manager for assistance in meeting the standards set in this policy.

Equal Employment Opportunity Applies Throughout The Employment Process To advance the principles of equal employment opportunity, SmithCo also extends this policy to every phase of the employment process including, but not limited to, recruitment, selection, placement, transfer, training and development, promotion, compensation, benefits, layoffs, termination, and all other conditions or benefits of employment. All employees are expected to abide by and promote this policy of equal employment opportunity within the organization, as well as with those who have a business relationship with SmithCo.

Equal Employment Opportunity Requires the Participation of All Associates While overall authority for implementing an Equal Employment Opportunity policy is assigned to the Vice President of Human Resources, an effective equal employment opportunity program cannot be achieved without the support of all associates. Any associate who feels they have been denied equal opportunity or subjected to discrimination should consult with their manager or HR representative. SmithCo's Employee Assistance Program also provides assistance with these matters.
