Which characteristic best describes a locking plate?\n|type=\"()\"}\n- It generates compression across the fracture by eccentric screw placement\n|| ''This describes a Dynamic Compression Plate (DCP), which generates compression through eccentric screw placement.''\n- It is used only for temporary fracture stabilization\n|| ''Temporary stabilization is more commonly achieved using devices such as external fixators.''\n+ It provides fixed-angle stability because the screws lock into the plate\n|| '''Locking plates use threaded holes that allow screws to lock into the plate, creating a fixed-angle construct that is especially useful in osteoporotic bone and comminuted fractures.'''\n- It is designed only for insertion into the medullary canal\n|| ''This describes an intramedullary nail rather than a locking plate.''\n\n{Which practice best helps prevent implant compatibility problems before an orthopedic procedure begins?\n|type=\"()\"}\n+ Confirm implants, guides, drivers, and accessories are from the same system\n|| '''Orthopedic implant systems are typically manufacturer-specific and should be used with their corresponding instrumentation unless compatibility has been formally established.'''\n- Opening several implant systems before confirming they are needed\n|| ''Opening unnecessary implant systems increases waste and complicates implant accountability.''\n- Arranging implants according to color and assembling them before surgery\n|| ''Implants should be organized according to system, type, and size rather than color.''\n- Selecting implants based on the scrub nurse's preference\n|| ''Implant selection is determined by the surgeon and operative plan.''\n\n{Why is it important for the scrub nurse to understand the stages of an orthopedic procedure?\n|type=\"()\"}\n- To determine the patient's postoperative rehabilitation plan\n|| ''Rehabilitation planning occurs after surgery and is outside the scrub nurse's role.''\n- To independently select implants during the operation\n|| ''Implant selection is the surgeon's responsibility.''\n- To decide when fluoroscopy should be used\n|| ''Imaging decisions are made by the surgeon according to the procedure.''\n+ To anticipate the sequence and prepare instruments at the right time\n|| '''Understanding the stages of surgery helps the scrub nurse organize instruments, anticipate upcoming steps, and maintain an efficient surgical workflow.'''\n\n{Which statement correctly describes cortical and cancellous screws?\n|type=\"()\"}\n- Cortical screws are intended only for locking plates, while cancellous screws are used only with dynamic compression plates\n|| ''Both screw types may be used with different fixation systems depending on the procedure.''\n+ Cortical screws have fine threads for dense bone, while cancellous screws have wider threads for softer bone\n|| '''Thread design allows each screw to obtain optimal purchase in the type of bone for which it is intended.'''\n- Cortical screws are always longer than cancellous screws\n|| ''Screw length varies according to the anatomy and procedure.''\n- Cancellous screws are used only during external fixation\n|| ''Cancellous screws are commonly used for internal fixation in cancellous bone.''\n\n{During preparation for fracture fixation, the surgeon requests an intramedullary nail. What is its primary purpose?\n|type=\"()\"}\n- Compressing bone fragments across a simple fracture\n|| ''Compression across the fracture line is achieved by devices such as Dynamic Compression Plates.''\n- Reshaping bone before fixation\n|| ''Bone reshaping is performed using instruments such as saws, osteotomes, or reamers.''\n+ Providing internal splinting of long bones such as the femur or tibia\n|| '''Intramedullary nails stabilize long bones by acting as internal splints within the medullary canal.'''\n- Temporarily holding fracture fragments during reduction\n|| ''Temporary stabilization during reduction is more commonly achieved with reduction clamps, K-wires, or external fixator pins.''\n\n{Which handling practice best maintains the sterility and integrity of orthopedic implants during surgery?\n|type=\"()\"}\n+ Handling implants with sterile forceps or designated holders\n|| '''Using sterile forceps or implant holders minimizes unnecessary handling and helps preserve sterility.'''\n- Opening all implant packages before the surgeon requests them\n|| ''Implants should be opened according to the operative plan and local policy to avoid unnecessary waste and maintain accountability.''\n- Returning opened implants to storage if they remain unused\n|| ''Orthopedic implants are single-use devices and must not be returned for future use once opened.''\n- Passing implants between team members by hand whenever possible\n|| ''Implants should be handled using appropriate sterile techniques and designated instruments to reduce contamination.''\n</quiz>{{Return to main}}{{Page data\n| part-of = Orthopedic Surgery - ECSACONM\n| keywords = surgery, health\n| sdg = SDG03 Good health and well-being\n| organizations = ECSACONM, SELF\n}}"}
