    Explanation
    Bumpers or bolsters are used on retention sutures to prevent the suture from cutting into the skin surface. By providing a cushioning effect, the bumpers or bolsters distribute the pressure evenly along the suture line, reducing the risk of tissue damage or cutting. This helps to promote proper wound healing and minimize complications such as infection or dehiscence.

    780. An abdominal wall defect may be reconstructed using

    • Gore-Tex patch

    • Heavy interrupted silk

    • Shouldice repair

    • Bassini repair

    Correct Answer
    A. Gore-Tex patch
    Explanation
    A Gore-Tex patch can be used to reconstruct an abdominal wall defect. Gore-Tex is a synthetic material that is biocompatible and durable, making it suitable for use in surgical repairs. It provides a strong and flexible barrier, helping to reinforce the weakened abdominal wall and prevent herniation. The patch can be sutured in place, providing support and allowing for tissue ingrowth over time. This technique is commonly used in abdominal wall reconstruction surgeries.

    801. A device that may obviate the need for an abdominoperineal resection because a low anterior anastomosis can be performed is a(n)

    • End-to-end anastomosis (EEA)

    • GIA

    • TA 55

    • LDS

    Correct Answer
    A. End-to-end anastomosis (EEA)
    Explanation
    An end-to-end anastomosis (EEA) is a surgical procedure that connects two ends of a hollow organ or blood vessel. In the context of the question, an EEA can be used to create a low anterior anastomosis, which is a surgical technique used to reconnect the colon or rectum to the anus after removing a portion of the lower bowel. By performing a low anterior anastomosis using an EEA, the need for an abdominoperineal resection, which involves removing the rectum and anus, can be obviated. Therefore, an EEA device may eliminate the need for a more extensive surgical procedure.

    733. When a sterile item is hanging or extending over the sterile table edge, the scrub nurse

    • Must watch closely that no one comes near it

    • Does not touch the part hanging below table level

    • Should pull it back onto the table so it does not become contaminated

    • May use the item

    Correct Answer
    A. Does not touch the part hanging below table level
    Explanation
    When a sterile item is hanging or extending over the sterile table edge, the scrub nurse must not touch the part hanging below table level. This is to ensure that the sterile field remains uncontaminated. Touching the part hanging below table level could introduce pathogens or contaminants onto the sterile item, compromising its sterility. Therefore, it is important for the scrub nurse to be vigilant and avoid touching the hanging part to maintain the integrity of the sterile field.

    746. When drop technique for an intestinal procedure is utilized

    • Two Mayo stands are used

    • Drapes and gloves do not need to be changed

    • Contaminated instruments are discarded, gloves are changed

    • A separate setup is used for the closure

    Correct Answer
    A. Contaminated instruments are discarded, gloves are changed
    Explanation
    When the drop technique is used for an intestinal procedure, contaminated instruments are discarded and gloves are changed. This is done to prevent the spread of infection and maintain a sterile environment. The drop technique involves dropping instruments into a sterile field without directly handling them, reducing the risk of contamination. However, if any instruments come into contact with the patient's body or any non-sterile surfaces, they are considered contaminated and must be discarded. Changing gloves is necessary to ensure that the surgical team does not transfer any contaminants while handling the instruments.

    750. An enzyme extract from bovine blood used as a topical hemostatic agent is

    • Oxytocin

    • Tannic acid

    • Thrombin

    • Collagen

    Correct Answer
    A. Thrombin
    Explanation
    Thrombin is a suitable enzyme extract from bovine blood for use as a topical hemostatic agent. Thrombin plays a crucial role in the blood clotting process by converting fibrinogen into fibrin, which forms a mesh-like structure to stop bleeding. As a result, thrombin promotes blood clot formation and aids in stopping bleeding, making it an effective hemostatic agent. Oxytocin is a hormone involved in childbirth and breastfeeding, tannic acid is a plant-derived compound with astringent properties, and collagen is a protein found in connective tissues.

    755. Dark Blood in the operative field may indicate that the patient is

    • Hyperkalemic

    • Hypovolemic

    • Hypotensive

    • Hypoxic

    Correct Answer
    A. Hypoxic
    Explanation
    Dark blood in the operative field may indicate that the patient is hypoxic. Hypoxia refers to a condition where there is a lack of oxygen supply to the tissues. When the blood is not adequately oxygenated, it appears dark in color. Therefore, the presence of dark blood in the operative field suggests that the patient may be experiencing a lack of oxygen, which can be indicative of hypoxia.

    744. A postoperative complication attributed to glove powder entering a wound is

    • Granulomata

    • Infection

    • Inflammation

    • Keloid formation

    Correct Answer
    A. Granulomata
    Explanation
    Glove powder entering a wound can lead to the formation of granulomata. Granulomata are small nodules that form as a result of the body's immune response to foreign substances. In this case, the glove powder acts as a foreign substance, causing an inflammatory reaction and the formation of granulomata. This complication can occur after surgery and may require further medical intervention to address the granulomata and prevent infection or further inflammation.

    Correct Answer
    A. Retention
    Explanation
    Sutures placed in a wound to prevent wound evisceration are called retention sutures. These sutures are used to hold the edges of the wound together and prevent the organs or tissues from protruding through the wound. They provide additional support and help in maintaining the integrity of the wound, reducing the risk of complications such as evisceration.
