of the perforated outer filter shield on a Poole abdominal suction tip is to, allow easier cleaning of the suction lumen., increase suction pressure for rapid fluid removal., control suction using a thumb hole on the handle., prevent tissue from being drawn into the suction apparatus., The main function of a probe during surgical exploration is to, improve visibility in deep wounds., remove obstructions from tubular organs., deliver irrigation solutions into the surgical field., explore the course of a wound without causing tissue trauma., The material commonly used for micro instruments for its strength and light weight is, aluminium., carbon fibre., titanium alloy., stainless steel., The purpose of spring handles in micro scissors is to, return tips to the open position., allow single-hand during operation., maintain grip during long procedures., prevent fingers from slipping during manipulation., The person to be informed before using electrical equipment in the operating room is, surgeon., scrub nurse., circulating nurse., anesthesia provider., The maximum vessel size that LigaSure can safely seal is, 3 mm., 5 mm., 7 mm., 10 mm., Krypton laser is mainly used in, cardiology., paediatric., gynaecology., ophthalmology., The purpose of packing the rectum with a moistened sponge during perineal laser surgery is to, absorb irrigation fluids., reduce heat transmission., maintain tissue moisture balance., prevent ignition from flammable methane gas., The primary purpose of the compression-decompression movement in microsurgical instrument handling is to, close and open forceps., adjust and optimize microscope focus., control and stabilize the suture tension., insert and position needles into fine tissues., What is the main challenge introduced by magnified visualization through an operating microscope?, Limited field and depth perception, Impaired tissue colour and texture differentiation, Reduced control over instrument alignment and movement, Increased fatigue due to bright illumination and prolonged use, Why is cool solution needed during long procedures using coaxial illumination?, Reduce the reflected glare, Maintain sterility of the wound, Clear debris from the optical path, Prevent tissue damage from radiant energy, Ultrasonic aspirator works by using, heat to melt tissues using ultrasound energy., high frequency vibrations to break down tissues., vibration with low frequency to cut through tissue layers., sound waves within the human hearing range to dissolve tissues., The advantage of using an ultrasonic aspirator for tumor emulsification is, increasing blood flow to the tumor site and side., minimizing trauma to nerves and blood vessels., enhancing radiation therapy for effectiveness and safety., eliminating the need for surgical intervention and evaluation., Applying a tourniquet to an extremity with arteriovenous (AV) fistula is contraindicated because it can, increase blood flow., reduce oxygen status., induce tissue necrosis., worse circulation problems., Which of the following tourniquet cuff pressures effectively suppress arterial circulation in the upper extremity?, 200mm Hg, 180mm Hg, 150mm Hg, 130mm Hg, What should be done with disposable suction catheters after use?, Reuse after rinse, Rinse with cold water, Keep for next procedure, Discard safely in biohazard waste, The purpose of dripping saline onto the bone during cutting with electrical instruments in surgery is to, keep the surgical instruments from overheating., prevent heat damage to bone and delay healing., sterilize the area before bone implants are placed., improve the absorption of anesthetic drugs into the bone., The advantage of the high-frequency current used by electrosurgical units during surgery is to, enhance blood flow., allow safe tissue cutting., minimize nerve damage., increase the strength of muscle contractions., Electrosurgery should not be used in the mouth, trachea, head, or pleural cavity as it will, lower the oxygen levels in the body., make the electrosurgery less effective., cause electrical problems with monitoring devices., start a fire due to the oxygen rich environment. 8888, Who is responsible for ensuring that all personnel in the laser room wear appropriate protective eyewear?, Surgeon, Anesthetist, Scrub nurse, Circulating nurse, The correct technique to pass instruments to the surgeon during microsurgery is, placing the instrument in the surgeon’s hand ready to use., looking at the operation area instead of the surgeon’s hand., leaving the instrument on the table for the surgeon to pick up., giving the instrument straight away even if it is not set for use., The recommended length for a tourniquet cuff to overlap at least, 1 to 4 inches., 3 to 6 inches., 6 to 10 inches., 7 to 12 inches., Broken fibre optics in a laparoscopic cable appear when viewed with the naked eye as, glowing red dots., bright shiny spots., smooth, clear lines., dark spots like pepper., The correct way to clean endoscope after use is, washing with plain water., soaking in detergent overnight., wiping only the outside with alcohol., using the manufacturer’s cleaning solution., How should keep the suction bottle after cleaning?, Wrapped in cloth, Left open to air dry, Placed upside down, Closed tightly with water inside, The flow of irrigation and suction during surgery on the disposable tip assembly is controlled by, surgeon., scrub person., circulating nurse., health care assistant.
