Question 1: Which of these elements is liquid at room temperature?

• mercury
• zinc
• manganese
• magnesium

Answer:

• mercury

Mercury is the only one of the elements listed here that is liquid at room temperature. The element bromine also has this property.Question 2: Referring to the attached passage, what is the name of the disease characterized by a high number of red blood cells?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.

• polycythemia
• thrombocytopenia
• anemia
• This condition was not mentioned in this passage.

Answer:

• polycythemia

The text states that a person may be diagnosed with polycythemia if his or her red blood cells counts are increased.

Question 3: Which of these is not mentioned in the accompanying text?

A quantitative descriptive study focused on the attitudes of nurses towards chronic pain found in the cancer patient population. The study sample was composed of 93 nurses from three hospitals with an average age of 30.54 years. Of these, 45.2% had a bachelor's degree.Throughout their professional careers, 91.4% of the nurses said they had acquired training in the assessment and treatment of pain. A small percentage, 18.3%, acquired this training through postgraduate studies or equivalent. However, 76.5% of these nurses found their training insufficient and experienced difficulties in the assessment of chronic pain in cancer patients.The study concluded that many nurses have little knowledge about cancer-related pain in the areas of pain assessment, pain management, psychological pain, spiritual pain, and the side effects of analgesic therapy. The results suggest the need for more training in the area of pain and pain assessment in this population.

• This study was influenced by independent variables.
• More than 30% of the nurses that participated in the study have a bachelor's degree.
• Nurses need more training in the area of pain.
• A small percentage of nurses acquired their training through postgraduate studies.

Answer:

• This study was influenced by independent variables.

Independent variables were not mentioned in this passage. The idea that nurses need more training in the area of pain and the statistics about the number of nurses who acquired their training through postgraduate studies and the number of nurses in the study who have a bachelor's degree were explicitly stated.

Question 4: What is the only artery in the body to carry oxygen-poor blood?

• renal artery
• interosseous artery
• vena cava
• pulmonary artery

Answer:

• pulmonary artery

Most arteries in the body carry oxygen-rich blood away from the heart, but the pulmonary artery carries oxygen-poor blood from the right ventricle of the heart to the lungs. The vena cava would not be correct because it is not an artery, it is a vein and the question asks for an artery.

Question 5: Who discovered the special theory of relativity?

• Albert Einstein
• Max Plank
• James Chadwick
• Alfred Nobel

Answer:

• Albert Einstein

The theory of relativity is one of physics' most famous theories and was proposed by Albert Einstein.Question 6: Which of these statements cannot be inferred from the attached passage?An allergy is defined as an "immunological hypersensitivity to a specific external stimulus" or, simply put, an exaggerated response of the immune system to a substance that is foreign to the body. Patients with allergies are called "atopic" or, more popularly, "allergic". The diagnosis of an allergy is mainly clinical and it can be aided by skin allergy tests and laboratory examinations.Skin allergy tests are fast, practical, and can be done in an allergy and immunology provider's

office. While skin tests are generally sufficient to confirm a diagnosis, doctors may also request complementary laboratory studies for further confirmation. These blood tests may diagnose an increase in white blood cells or antibodies for common allergy triggers, such as pet dander, grasses, and molds. Blood tests may help confirm or exclude the possibility of an allergy and, consequently, reduce adverse reactions caused by unnecessary medication. A correct diagnosis, along with proper treatment based on the valid results of allergy tests, will help reduce or eliminate the incidence of symptoms and improve the patient's quality of life.

• Skin tests are the most accurate way to confirm an allergy test.
• It would be wise to seek a correct diagnosis and treatment of allergies.
• Giving medicine for an allergy that does not exist can be harmful.
• The term allergic is used more than atopic when referring to people with allergies

Answer:

• Skin tests are the most accurate way to confirm an allergy test.

While the text mentions that skin tests are "generally sufficient" to confirm an allergy, further detailed testing is sometimes needed for confirmation.The other answer choices are not specifically stated in the passage, but you can infer them from information that is given by the author.Question 7: Which statement can correctly be inferred from the accompanying passage?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,

• The test of red blood cells is more informative than the tests of white blood cells and

platelets.
