    • A newborn screening blood spot

    • Blood in a thick malaria smear

    • Lipemia in a bilirubin specimen

    • The thinnest area of a blood film

    Correct Answer
    A. The thinnest area of a blood film
    Explanation
    The term "feather" is used to describe the thinnest area of a blood film. When preparing a blood film for microscopic examination, a drop of blood is spread thinly and evenly across a glass slide. The feathered edge refers to the tapered, thin area of the blood film where the cells are more spread out and easier to visualize under the microscope. This area is important for identifying and analyzing blood cells and their characteristics.

    The ability of oxygen to combine with this substance in the red blood cells increases the amount of oxygen that can be carried in the blood by up to 70 times

    • Carbon dioxide

    • Glucose

    • Hemoglobin

    • Potassium

    Correct Answer
    A. Hemoglobin
    Explanation
    Hemoglobin is a protein found in red blood cells that is responsible for carrying oxygen throughout the body. It has a unique structure that allows it to bind with oxygen molecules, forming a reversible complex. This ability of hemoglobin to combine with oxygen greatly enhances the amount of oxygen that can be transported in the blood. In fact, hemoglobin can increase the carrying capacity of oxygen by up to 70 times. This ensures that oxygen is efficiently delivered to the body's tissues and organs, supporting their proper functioning.

    What is the purpose of an antiglyolytic agent

    • Enhance the clotting process

    • Inhibit electrolyte breakdown

    • Preserve glucose

    • Prevent clotting

    Correct Answer
    A. Preserve glucose
    Explanation
    The purpose of an antiglycolytic agent is to preserve glucose. Antiglycolytic agents are substances that inhibit the breakdown of glucose in a sample, usually blood or urine, by preventing the action of enzymes that break down glucose. This preservation of glucose is important in certain laboratory tests where accurate measurement of glucose levels is required. By preserving glucose, antiglycolytic agents help ensure that the glucose levels in the sample remain stable and can be accurately measured.

    Laboratory results can be negaitvely affected if the phlebotomist

    • Awakens a sleeping patient and raises the head of the patients bed

    • Collects a specimen in dim lighting conditions in the patients room

    • Draws a specimen from an unconscious patient without assistance

    • Statles a patient who is asleep while preparing to collect a specimen

    Correct Answer
    A. Statles a patient who is asleep while preparing to collect a specimen
    Explanation
    If the phlebotomist startles a sleeping patient while preparing to collect a specimen, it can negatively affect the laboratory results. This is because sudden movements or surprises can cause the patient to have a stress response, leading to an increase in certain hormones and chemicals in the body. These changes can potentially alter the composition of the blood or other bodily fluids being collected, which may in turn affect the accuracy of the laboratory results.

    It is imporant to fill anticoagulant tubes to the proper lvel to ensure that

    • The specimen yields enough serum for the required tests

    • There is a proper ratio of blood to anticoagulant additive

    • There is an adequate amount of blood to perform the test

    • Issue fluid contamination of the specimen is minimized

    Correct Answer
    A. There is a proper ratio of blood to anticoagulant additive
    Explanation
    Filling anticoagulant tubes to the proper level ensures that there is a proper ratio of blood to anticoagulant additive. This is important because the anticoagulant additive prevents the blood from clotting and allows for accurate testing. If the ratio is not correct, it can affect the validity of the test results. Therefore, it is essential to fill the tubes to the proper level to ensure the correct ratio and accurate testing.

    A blood smear prepared from an EDTA specimen should be made

    • After the blood cells settle in the tube

    • At the time the specimen is collected

    • Before the specimen has been mixed

    • Within 1 hour of specimen collection

    Correct Answer
    A. Within 1 hour of specimen collection
    Explanation
    A blood smear prepared from an EDTA specimen should be made within 1 hour of specimen collection because EDTA is an anticoagulant that prevents blood from clotting. If the blood smear is not made within this time frame, the blood cells may begin to degrade and the quality of the smear may be compromised. Therefore, it is important to prepare the blood smear as soon as possible after the specimen has been collected to ensure accurate results.

    A bleeding time ( BT) test assesses the functioning of which of the following cellular elements

    • Erythrocytes

    • Leukocytes

    • Neutrophils

    • Thrombocytes

    Correct Answer
    A. Thrombocytes
    Explanation
    A bleeding time (BT) test assesses the functioning of thrombocytes. Thrombocytes, also known as platelets, are cellular elements in the blood that play a crucial role in blood clotting. They help in the formation of a clot to stop bleeding by sticking together and forming a plug at the site of injury. Therefore, a BT test is used to evaluate the ability of thrombocytes to form a clot and assess the overall functioning of these cellular elements in the blood.
