Question 1

The study of antigen-antibody reactions to assess the presence of a substance or to determine the presence of disease is known as

Accepted Answer

Immunology and blood banking is the study of antigen-antibody reactions and is used to assess the presence of a substance or to determine the presence of disease. Hematology is the study of blood and blood-forming tissues. Clinical chemistry is the study of body fluids and their chemical composition. Cytology is the study of cells. Histology is the study of the microscopic structure of tissues. None of these specifically involve antigen-antibody reactions to the extent that immunology and blood banking does.

Question 2

Detection of abnormal cells is known as

Accepted Answer

Detection of abnormal cells is typically done through cytology, which involves examining cells under a microscope to identify any abnormalities or changes in cell structure. Hematology focuses on the study of blood cells, immunology and blood banking are related to blood transfusions and disease immunity, clinical chemistry analyzes blood and bodily fluids for chemical changes, and histology involves the study of tissues and cell structure.

Question 3

What is the purpose of performing a routine test?

Accepted Answer

C

Question 4

Which of the following is an example of using a laboratory test to regulate treatment?

Accepted Answer

Testing blood glucose levels is a laboratory test used to guide insulin dosing in diabetic patients. The other options (B, C, and D) involve laboratory tests that may diagnose a condition but do not guide treatment dosing.

Question 5

Which of the following assists the physician in making a diagnosis?

Accepted Answer

All of the given options (health history, physical examination, laboratory tests, and diagnostic tests) are important in assisting the physician in making a diagnosis. They provide important information about the patient's condition and help the physician identify the underlying cause of the symptoms.

Question 6

How are laboratory reports delivered to the medical office?

Accepted Answer

Laboratory reports can be delivered to a medical office through various methods including fax, mail, hand-delivery by a laboratory courier, and electronically. This ensures flexibility and efficiency in communication between laboratories and medical offices.

Question 7

The study of blood and the blood-forming tissues is known as

Accepted Answer

The study of blood and the blood-forming tissues is known as Hematology.

Question 8

All of the following are reasons for indicating the clinical diagnosis on the laboratory request form except

Accepted Answer

The answer of All of the following are reasons for...

Question 9

What is a profile?

Accepted Answer

A profile refers to a set of laboratory tests or analysis that are grouped together to identify or diagnose a particular disease or condition. Therefore, option C - an array of laboratory tests for identifying a disease - best defines a profile.

Question 10

All of the following are included on a laboratory request form except the

Accepted Answer

The laboratory test results are not included on the laboratory request form; they are generated by the laboratory after performing the requested tests. The other options, including the physician's name and address, patient's age and gender, date and time of collection of the specimen, and source of the specimen, are all important pieces of information that should be included on the laboratory request form.

Question 11

What is the purpose of a laboratory report?

Accepted Answer

The purpose of a laboratory report is to relay the results of laboratory tests to the physician, so they can use the information to diagnose and treat the patient. It does not indicate the patient's diagnosis, prognosis, or order laboratory tests.

Question 12

Which of the following is an example of using a laboratory test to assist in the differential diagnosis of a patient's condition?

Accepted Answer

Performing a strep test to determine if a patient has strep throat or pharyngitis is an example of using a laboratory test to assist in the differential diagnosis of a patient's condition. This test helps to differentiate between a bacterial infection (strep throat) and a viral infection (pharyngitis).

Question 13

Which of the following occurs when the body is in homeostasis?

Accepted Answer

Homeostasis refers to the body's ability to maintain a stable internal environment. In this state, all bodily functions are operating normally and within a narrow range of values. As a result, laboratory test results will fall within the reference range. A and B are incorrect because laboratory test results outside the reference range indicate an imbalance in the body. D is incorrect because laboratory test results are valid regardless of whether the body is in homeostasis or not.

Question 14

What is the purpose of the patient accession number found on the laboratory report?

Accepted Answer

The patient accession number is used to identify each specimen in the laboratory. It allows for tracking of the specimen and correct association of results with the correct patient.

Question 15

All of the following are guidelines for storing specimens and testing components in a laboratory refrigerator except

Accepted Answer

The temperature of the refrigerator should be checked daily, not just once each week, to ensure it remains within the required range for specimen storage.

Question 16

All of the following are advantages of the laboratory component of an EMR program except

Accepted Answer

The laboratory component of an EMR program does not determine the type of tests required by the patient. This is determined by the healthcare provider after an assessment of the patient's condition and needs. However, laboratory requests can be completed on the computer, transmitted electronically to the medical laboratory, and plotted on a flow sheet for routine monitoring.

Question 17

All of the following are included in a lipid profile except

Accepted Answer

Glucose is not a component of a lipid profile, which is a blood test used to measure the levels of different types of cholesterol and triglycerides in the blood. The lipid profile includes total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides.

Question 18

What temperature is usually required for storing testing materials and performing laboratory tests?

Accepted Answer

Room temperature is usually required for storing testing materials and performing laboratory tests. This is typically around 20-25°C or 68-77°F. Storing materials at this temperature helps ensure accuracy and consistency of results.

Question 19

Which of the following is not found in a laboratory directory?

Accepted Answer

The answer of Which of the following is not found...

Question 20

The purpose of patient preparation for a laboratory test is to

Accepted Answer

Patient preparation is an important step in laboratory testing as it aims to provide a specimen that yields accurate test results. Preparation may include fasting, avoiding certain medications or activities, or following specific instructions from the healthcare provider to ensure the specimen is not contaminated or altered in any way. Accurate test results can help with diagnosis, treatment, and monitoring of patients, making patient preparation essential for optimizing patient care.
