Lab Values Quiz : Questions And Answers

The correct answer is Renal system primarily. Urinalysis is a diagnostic test that examines the urine to evaluate the health of the kidneys and urinary system. The renal system, which includes the kidneys, ureters, bladder, and urethra, is responsible for filtering waste products from the blood and producing urine. Therefore, the primary body system that relates to the urinalysis test is the renal system.

A CBC (Complete Blood Count) test would be ordered to diagnose anemia. This test measures various components of the blood, including red blood cells, white blood cells, and hemoglobin levels. In the case of anemia, the CBC test would show a decrease in red blood cells and/or hemoglobin levels, indicating a lower than normal oxygen-carrying capacity of the blood. The glucose test, cholesterol test, and BUN (Blood Urea Nitrogen) test are not specific to diagnosing anemia and would not provide relevant information in this case.

The CBC test, which stands for Complete Blood Count, is a blood test that provides information about the cells in the blood, including red blood cells, white blood cells, and platelets. The hematologic system, also known as the circulatory system, is responsible for the production, function, and regulation of these blood cells. Therefore, the hematologic (circulatory) system is the body system that relates to the CBC test.

The normal value that goes with electrolyte Na+ is 136-145 mEq/L. This range represents the normal levels of sodium ions in the blood. Sodium is an essential electrolyte that helps maintain fluid balance in the body and is important for nerve and muscle function. Deviations from this range can indicate certain medical conditions or imbalances in the body's sodium levels.

A coagulation study is a test that evaluates the blood's ability to clot. It is used to diagnose bleeding disorders or monitor the effectiveness of anticoagulant medications. Since coagulation is a process that occurs within the blood, the study would be primarily done on the circulatory/hematologic system. This system includes the heart, blood vessels, and blood cells, which are directly involved in the clotting process. The other options mentioned, such as the metabolic, genitourinary, and hepatic systems, are not directly related to coagulation.

The normal value for the electrolyte K+ (potassium) is 3.5-5.0mEq/L. This range represents the typical concentration of potassium in the blood. Potassium is an essential electrolyte that plays a crucial role in various bodily functions, including muscle contractions, nerve impulses, and maintaining proper fluid balance. Deviations from this normal range can indicate an imbalance in potassium levels, which can have significant health implications. Therefore, it is important to monitor and maintain potassium levels within the normal range.

The normal range for platelets in the blood is 150,000-400,000. Platelets are important for blood clotting and preventing excessive bleeding. If the platelet count falls below 150,000, it may indicate a condition called thrombocytopenia, which can lead to increased bleeding. On the other hand, a platelet count above 400,000 may suggest a condition called thrombocytosis, which can increase the risk of blood clot formation. Therefore, the range of 150,000-400,000 is considered normal for platelet count.

The percentage of RBCs in the blood determines the bloods viscosity

An elderly client with renal insufficiency may show deviations from normal lab reference ranges because renal insufficiency can affect the functioning of the kidneys, which play a crucial role in maintaining the balance of various substances in the body. The kidneys filter waste products and regulate electrolyte levels, so when they are not functioning properly, there can be abnormalities in lab results such as elevated levels of creatinine, urea, or electrolyte imbalances. This is why an elderly client with renal insufficiency is more likely to have deviations from normal lab reference ranges.

The normal lab values for hematocrit are 37-47% for males and 42-52% for females. Hematocrit is a measure of the proportion of red blood cells in the blood. These ranges indicate the percentage of blood volume that is occupied by red blood cells. The values for males and females differ slightly due to physiological differences between the sexes.

The normal value that goes with electrolyte Ca is 9.0-10.5mg/dl. This range represents the normal levels of calcium in the blood. Calcium is an important electrolyte that is necessary for various bodily functions, including muscle contraction, nerve transmission, and bone health. Maintaining the proper balance of calcium in the blood is crucial for overall health and wellbeing.

The given answer, 20-40%, is the correct range for normal lab values of lymphocytes. Lymphocytes are a type of white blood cell that play a crucial role in the immune system. The normal range for lymphocytes is typically between 20% and 40% of the total white blood cell count. This range may vary slightly depending on the specific laboratory or reference range used. It is important to monitor lymphocyte levels as they can indicate various health conditions, such as infections, autoimmune disorders, or certain types of cancer.

The normal lab value for WBC (white blood cell count) is 5,000-10,000/mm3. This range indicates a normal level of white blood cells in the body, which is essential for a healthy immune system. White blood cells help to fight off infections and protect the body against diseases. A WBC count higher or lower than this range may indicate an underlying health condition or infection.

These values represent the percentage of red blood cells (RBCs) in the blood and are used to assess a person's blood volume and oxygen-carrying capacity. They can vary slightly depending on the laboratory and the individual's age and other factors, but the range you provided is generally accepted as the normal reference range for hematocrit.

The correct answer is 32-36%. MCHC stands for Mean Corpuscular Hemoglobin Concentration, which is a measure of the average concentration of hemoglobin in a given volume of packed red blood cells. The normal range for MCHC is 32-36%, indicating the normal concentration of hemoglobin in red blood cells.

The correct answer is 3-5%. This refers to the normal laboratory value range for the percentage of white blood cells (WBC) that are neutrophils in their band form. Neutrophils are a type of white blood cell that helps the body fight off infections. In a healthy individual, 3-5% of the total WBC count should consist of band neutrophils. This range is considered normal and indicates a properly functioning immune system.

The correct answer is 0.5-1% because basophils are a type of white blood cell that play a role in the immune response to allergic reactions and parasitic infections. In a normal blood sample, basophils typically make up around 0.5-1% of the total white blood cell count. This range is considered within the normal range for basophils in a healthy individual.

The correct answer is 55-70%. This range represents the normal lab value for WBC Neutrophils (Segs). Neutrophils are a type of white blood cell that play a crucial role in the body's immune response. A percentage of 55-70% indicates a healthy balance of neutrophils in the blood, which is important for fighting off infections and maintaining overall immune function.

The normal lab values for RBC (red blood cell) count are 4.7-6.1 million per microliter (m/pl) for males and 4.2-5.4 million per microliter (M/O) for females. This indicates the normal range of red blood cells present in the blood of males and females.

The normal value for electrolyte Cl- is 98-106 mEq/L. This range represents the typical concentration of Cl- in the body. Electrolytes are essential for various bodily functions, including maintaining fluid balance, transmitting nerve impulses, and regulating muscle contractions. Therefore, it is important for the Cl- levels to fall within the normal range to ensure proper functioning of the body.

The correct answer is 27-31pg. MCH stands for Mean Corpuscular Hemoglobin, which measures the average amount of hemoglobin in each red blood cell. The normal value for MCH is typically between 27-31pg, indicating a healthy amount of hemoglobin in the red blood cells.

The correct answer is 2-8%. This range represents the normal laboratory values for monocytes, which are a type of white blood cell. Monocytes play a crucial role in the immune system by engulfing and destroying pathogens. The percentage range provided indicates the proportion of monocytes in the total white blood cell count. A percentage within the range of 2-8% is considered normal and indicates a healthy immune response.

The correct answer is "Follow the procedure exactly as outlined in Pagana and Pagana text." This option is not a routine nursing intervention when collecting laboratory specimens because the procedure for collecting laboratory specimens may vary depending on the specific test being conducted and the healthcare facility's protocols. Nurses should follow the specific guidelines and protocols provided by the facility rather than relying solely on a specific textbook.

The normal value for MCV (Mean Corpuscular Volume) is 80-95um3. MCV measures the average size of red blood cells, and a value within this range indicates that the red blood cells are of normal size. Values outside of this range may indicate certain medical conditions or disorders.

The correct answer is 1-4%. This range represents the normal laboratory value for WBC Eosinophils (EOS). Eosinophils are a type of white blood cell that play a role in the immune response, particularly in allergic reactions and parasitic infections. The normal range of eosinophils in the blood is typically low, ranging from 1-4% of the total white blood cell count. Higher levels of eosinophils may indicate an allergic reaction, asthma, or certain infections, while lower levels may be seen in certain types of leukemia or bone marrow disorders.

The correct answer is 11-14.5%. RDW stands for Red Cell Distribution Width, which measures the variation in size of red blood cells. A normal RDW value is typically between 11-14.5%, indicating that the red blood cells are relatively uniform in size.

The normal pH range for most biological systems, including the human body, falls within the range of 6.5-7.5. This range is considered optimal for the proper functioning of enzymes and other biochemical processes in the body. pH values outside of this range can indicate imbalances and potential health issues.

The correct answer is 6-25. This range represents the normal blood urea nitrogen (BUN) to creatinine ratio. BUN is a waste product that is filtered out of the blood by the kidneys, while creatinine is a waste product produced by the muscles. The ratio of BUN to creatinine can provide information about kidney function. A ratio within the range of 6-25 is considered normal and indicates that the kidneys are functioning properly.

A glucose test is primarily done for the hepatic system, which refers to the liver. The liver plays a crucial role in regulating blood glucose levels by producing and releasing glucose as needed. Therefore, a glucose test is used to assess the liver's ability to maintain proper glucose levels in the body. This test helps in diagnosing and monitoring conditions such as diabetes, liver diseases, and metabolic disorders that affect the hepatic system's functioning.

The test that would primarily be done for nutritional, hepatic, circulatory, and metabolic issues is the metabolic test. This test helps to assess the body's overall metabolic function, including the breakdown and utilization of nutrients, liver function, and circulation. The integumentary system, which includes the skin, is not directly involved in these processes and therefore would not be the primary focus of testing in this case.
