    The color of normal serum is usually __________.

    • A.

      Straw to yellow

    • B.

      Milky white

    • C.

      Clear red

    • D.

      Hazy brown

    Correct Answer
    A. Straw to yellow
    Explanation
    Normal serum is usually straw to yellow in color. This is because serum is the clear, yellowish fluid that remains after blood has clotted and the blood cells have been removed. The color of serum is determined by various factors, including the presence of certain pigments and proteins. In a healthy individual, the serum is typically a pale yellow color, resembling straw. This color can vary slightly depending on the individual's hydration status and diet.

    Which of the following conditions would stop a phlebotomist from drawing blood from a patient's vein?

    • A.

      Same side mastectomy

    • B.

      Recent heart attack

    • C.

      IV in the opposite arm

    • D.

      Active tuberculosis

    Correct Answer
    A. Same side mastectomy
    Explanation
    A phlebotomist would avoid drawing blood from an arm on the same side as a mastectomy. This is because lymph node removal or damage during mastectomy can lead to complications such as lymphedema, which can be exacerbated by blood draws or the application of pressure to the limb. Therefore, out of the conditions listed, a same-side mastectomy would be a contraindication for venipuncture on that side.

    Chemicals that precent blood from clotting are called __________.

    • A.

      Preservatives

    • B.

      Activators

    • C.

      Anticoagulants

    • D.

      Adhesives

    Correct Answer
    C. Anticoagulants
    Explanation
    Anticoagulants are chemicals that prevent blood from clotting. They work by inhibiting the formation of blood clots, which can be harmful and lead to conditions such as deep vein thrombosis or stroke. Unlike preservatives, which are substances used to prevent decay or spoilage, or activators, which initiate or enhance a chemical reaction, anticoagulants specifically target the clotting process in the blood. Adhesives, on the other hand, are substances used to bind or stick things together, and are unrelated to blood clotting.

      Chemistry

    • B.

      Blood banking

    • C.

      Hematology

    • D.

      Microbiology

    Correct Answer
    C. Hematology
    Explanation
    Red and white blood cell counts are examples of hematology tests because hematology is the branch of medicine that deals with the study of blood, blood-forming organs, and blood diseases. This branch specifically focuses on the examination of blood cells, including red blood cells and white blood cells, to diagnose and monitor various conditions and diseases related to the blood. Therefore, hematology is the correct answer in this context.

    Explanation
    Antibiotics are drugs that are specifically designed to destroy or kill bacteria that cause disease. They work by targeting the structure or function of bacteria, either by inhibiting their growth or by directly killing them. Disinfectants, germicides, and sterilizers are all types of agents that are used to kill or eliminate microorganisms, but they are not specifically targeted towards bacteria. Therefore, the correct answer is antibiotics.

      Arterial pressure

    Correct Answer
    A. Systolic pressure
    Explanation
    During the contraction of the heart, known as systole, blood is forcefully pumped out of the heart into the arteries. This results in a peak pressure that is exerted on the walls of the arteries. This peak pressure is referred to as systolic pressure. It represents the maximum pressure within the arterial system and is typically measured as the higher value in a blood pressure reading.

    Which of the following is not known to transmit HIV?

    • A.

      Vaginal secretions

    • B.

      Breast milk

    • C.

      Semen

    • D.

      Sweat

    Correct Answer
    D. Sweat
    Explanation
    Sweat is not known to transmit HIV because the virus cannot survive outside the human body for long periods of time. HIV is primarily transmitted through specific bodily fluids such as blood, semen, vaginal secretions, and breast milk, which contain a high concentration of the virus. However, sweat does not contain enough HIV to transmit the infection, making it an unlikely mode of transmission.
