Question 1

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 2

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

Accepted Answer

Laboratory test results are not included on a laboratory request form, as the purpose of the form is to request the tests to be performed, not to provide the results. The other options (A, B, C, D) are typically included on a laboratory request form.

Question 3

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

Accepted Answer

Homeostasis refers to the state of balance and stability in the body's internal environment. When the body is in homeostasis, all physiological functions are within normal range, and laboratory test results fall within the reference range. A is incorrect because laboratory test results above the reference range indicate an abnormality or pathology. B is incorrect because an imbalance refers to a deviation from homeostasis. D is incorrect because laboratory test results can only be determined to be invalid if there was an error in the testing process.

Question 4

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

Accepted Answer

The patient accession number is used to provide identification of each specimen in the laboratory. This number helps to ensure that the correct results are reported for each patient and that there is no mix-up or confusion between different specimens.

Answer: E
 While the patient accession number primarily serves to identify each specimen in the laboratory, it also serves other purposes such as providing information for third-party billing and assisting the physician in making a diagnosis. Additionally, it may be used to identify the source of the specimen and ensure that it was collected from the correct patient. Therefore, choice E - "All of the above" - is the best answer.

Question 5

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

Accepted Answer

All of the choices (health history, physical examination, laboratory tests, and diagnostic tests) can provide valuable information that assists the physician in making a diagnosis. A complete evaluation typically includes a combination of these methods.

Question 6

What is the purpose of performing a routine test?

Accepted Answer

The answer of What is the purpose of performing a...

Question 7

Detection of abnormal cells is known as

Accepted Answer

Abnormal cells are typically identified using cytological techniques such as examining cells under a microscope. This makes cytology the best choice for the detection of abnormal cells.

Question 8

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

Accepted Answer

Hematology is the study of blood and the blood-forming tissues.

Question 9

What is a profile?

Accepted Answer

A profile is an array of laboratory tests that are done together to identify a disease or medical condition. It is a type of diagnostic test that helps in the evaluation of a patient's health status. A profile typically consists of several laboratory tests that are grouped together based on the condition being evaluated. These tests can include blood tests, urine tests, imaging studies, and other types of diagnostic tests.

Question 10

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 is a specific laboratory test used to differentiate between various conditions such as strep throat and pharyngitis. The other options are not as specific and may not provide a definitive diagnosis.

Question 11

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

Accepted Answer

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

Question 12

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

The study of antigen-antibody reactions is a major part of immunology and blood banking, which involves the testing of blood and other bodily fluids for the presence of antigens and antibodies. Hematology is the study of blood cells and disorders, clinical chemistry deals with the analysis of bodily fluids such as urine and blood for diagnosing diseases, cytology focuses on the study of cells, and histology involves the examination of tissue samples. None of these options specifically address the use of antigen-antibody reactions for assessing the presence of a substance or disease.

Question 13

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

Accepted Answer

Monitoring blood glucose levels through laboratory testing is a common way to regulate insulin dosage in diabetic patients.

Question 14

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

Accepted Answer

Instructions for testing specimens are typically not included in a laboratory directory, which primarily focuses on test names, codes, preparation, specimen requirements, and handling/storage.

Question 15

The purpose of patient preparation for a laboratory test is to

Accepted Answer

Patient preparation for a laboratory test aims to provide a specimen that yields accurate test results. This can include specific instructions such as fasting before a blood draw or avoiding certain medications. Patient preparation does not ensure that test results fall within the normal range or that the patient receives the proper treatment, but rather it provides the laboratory with the best possible specimen for analysis.

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 cannot determine the type of tests required by the patient. This decision requires the input of a healthcare provider based on the patient's medical history and current health status. The other options listed are advantages of the laboratory component of an EMR program.

Question 17

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. This allows the physician to make informed decisions about the patient's healthcare. Laboratory reports do not indicate the patient diagnosis or prognosis, and they do not order laboratory tests on a patient.

Question 18

All of the following are included in a lipid profile except

Accepted Answer

Glucose is not included in a lipid profile, as it is a measure of blood sugar levels and not related to lipid metabolism. Lipid profile typically includes measures of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides.

Question 19

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

Accepted Answer

Room temperature (typically between 68-77°F, or 20-25°C) is the most common temperature range for storing testing materials and performing laboratory tests. It is important to maintain a consistent temperature to ensure accurate and reproducible results. Extreme temperatures (very cold or very hot) can affect the integrity of the materials and compromise the validity of the tests. Body temperature and a temperature between 100°F and 104°F are not appropriate for laboratory testing.

Question 20

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.
