Exam 7: Surgical Modalities

The design of laparoscopic instruments aims to provide a clamping,cutting,dissecting,electrocoagulating,suturing,or stapling instrument on the tip of a shaft that is long or short enough to reach the target tissue.The hand control on the surgeon's end of the instrument is engineered to provide:

The nursing research and practice committee searched the scientific literature for information on smoke evacuation,as they planned for a unit-wide initiative to use this safety measure on all procedures where smoke or plume is generated.Their main concern is that the surgeons will not be as willing to comply as the staff.Select the safety measure that will be the most critical and most challenging to enforce.

Flexible fiberscopes and flexible videoscopes share many of the same components;however,in a video gastroscope,the eyepiece and lens of the fiberscope are replaced by a:

MATCHING Flexible endoscopes,whether they are a fiberscope with an eyepiece lens or a videoscope,have four distinct components.Match each component with its descriptive statement by drawing a line from the component part name below to the appropriate component part on the image. a.Control body b.Insertion tube c.Light guide connector d.Bending section -Suction,air,water,and light connection adaptors to energy source

Clair Townsend arrived at the endoscopy center 2 days before her scheduled interventional bronchoscopy to receive an injection of a photosensitive intravenous dye that the pulmonologist explained would highlight the dysplastic tissues of her bronchi that were precancerous.He scheduled her for an ablative procedure called photodynamic therapy (PDT),where the highlighted tissues would be affected by the laser light that is color-specific for uptake of the dye.Select the laser that would be appropriate to use on this patient during a PDT bronchoscopy.

The challenge of suturing intra-abdominally is not as great as the process needed to tie and tighten the surgical knot.The knot-tying process can be achieved within or outside of the abdominal compartment.One technique uses laparoscopic grasping forceps and a laparoscopic needle holder only,and another uses the same instruments plus two obturator sleeves to push,slide,and tighten the knot into place.When sutures are tied and knotted during an open procedure,the surgeon may tie the knot with gloved fingers,called a one- or two-handed tie,or wrap the suture around the tip of a needle holder and grasp the other end of the suture to pull it through the wrapped coils;this is called an instrument tie.The intracorporeal suture technique uses the suture-tying process analogous to the:

High-pressure insufflation rates can cause increased intra-abdominal pressure that can result in life-threatening sequelae.The perioperative nurse reduces the flow rate in collaboration with the surgeon,while monitoring the patient for signs of:

Susie Reynolds,a 9-year-old softball player,has arrived in the OR for emergency repair of superficial facial and deep arm lacerations when she ran into the chain link fence during practice after school.The perioperative nurse discovers that Susie has diabetes and has an insulin pump that should remain connected during the short procedure.The best option for energy-generated hemostasis is:
