    how long should a patient fast when going for a glucose or cholesterol testing?

    Explanation
    When going for a glucose or cholesterol testing, it is recommended for a patient to fast for 12 hours. Fasting helps to obtain accurate results as it ensures that the food consumed does not interfere with the test. By not eating or drinking anything except water for 12 hours before the test, the patient's body has enough time to process and metabolize the glucose and cholesterol levels, providing a more reliable measurement.

    what are the three general methods for the collection of a specimen?

    Explanation
    The correct answer is venipuncture, capillary puncture, and arterial puncture. Venipuncture involves the collection of blood from a vein, usually in the arm, using a needle and syringe or vacuum tube. Capillary puncture, also known as a fingerstick or heelstick, is the collection of a small amount of blood from the capillaries in the fingertip or heel. Arterial puncture involves the collection of blood from an artery, typically in the wrist, and is done to measure blood gases and other parameters.

  • 6. 

    if arm veins can't be used, what other areas are?

    Explanation
    When arm veins cannot be used, the basilic vein and dorsal hand veins can be used as alternative areas for medical procedures. The basilic vein is located in the upper arm and is commonly used for venipuncture and blood draws. The dorsal hand veins are located on the back of the hand and can be accessed for intravenous therapy or blood collection. These alternative areas provide accessible and reliable veins for medical procedures when arm veins are not available.

  • 7. 

    What areas to avoid during venipuncture?

    Explanation
    During venipuncture, it is important to avoid areas with hematoma or scars of previous mastectomy. This is because these areas may be more sensitive or prone to bleeding, which can make the procedure more difficult and increase the risk of complications. Additionally, scars from previous mastectomy may have altered blood flow or damaged blood vessels, making it harder to successfully draw blood. Therefore, it is best to choose a different site for venipuncture to ensure a safe and successful procedure.

    Rate this question:

  • 8. 

    What is a hematoma?

    Explanation
    A hematoma is an abnormal collection of blood outside of a blood vessel. It occurs due to damage to the wall of a blood vessel, such as an artery, vein, or capillary, causing blood to leak into surrounding tissues. Hematomas can vary in size, ranging from a small dot of blood to a larger collection that causes significant swelling.

    Rate this question:

  • 9. 

    Which veins lack resilience?

    Explanation
    Thrombosed veins lack resilience because they are blocked by a blood clot, preventing them from expanding and contracting normally. This lack of resilience can lead to pain, swelling, and a feeling of heaviness in the affected area. Thrombosed veins are commonly seen in conditions such as deep vein thrombosis (DVT) or thrombophlebitis, where the blood clot forms in a vein and causes inflammation. Prompt treatment is necessary to prevent complications such as pulmonary embolism.

    Rate this question:

  • 10. 

    when performing venipuncture, the needle should be at a: 

    Explanation
    When performing venipuncture, the needle should be inserted at a 15-30 degree angle. This angle allows for proper entry into the vein while minimizing the risk of puncturing through the vein or causing excessive pain to the patient. Inserting the needle at a steeper angle may increase the likelihood of going through the vein, while a shallower angle may make it difficult to properly access the vein. Therefore, a 15-30 degree angle is considered the optimal range for venipuncture.

    each sample must have a ______________ to be submitted to the laboratory.

    Explanation
    To ensure that each sample is properly identified and processed, it must have a requisition form attached when submitted to the laboratory. This form contains important information such as the patient's name, date and time of collection, type of sample, and any specific tests requested. The requisition form serves as a crucial document for the laboratory staff to accurately track and handle each sample, ensuring efficient and reliable testing.

    when collecting blood from newborns, the penetration depth of lancets should be:

    Explanation
    When collecting blood from newborns, the penetration depth of lancets should be less than 2.0mm. This is because newborns have delicate and sensitive skin, and using a deeper penetration depth may cause unnecessary pain and discomfort to the baby. Additionally, a shallow penetration depth reduces the risk of injury or damage to the underlying blood vessels and tissues. Therefore, it is important to use lancets with a penetration depth of less than 2.0mm to ensure a safe and comfortable blood collection process for newborns.
