1. mode ultrasound projects a two-dimensional image on an oscilloscope screen. The image appears as dots from the echoes of the signal. 2. Duplex ultrasound is a combination of the pulse Doppler and the real time B. mode image ultrasonogram. 3. Angiography is a study used to evaluate the vascular system using fluoroscopy and contrast medium. - Answer-INFO A 3-way Foley catheter with a 30 cc balloon should be inserted following a transurethral prostate resection (TURP) to A. irrigate and facilitate hemostasis. B. prevent the patient from getting out of bed. C. keep accurate input and output records. D. minimize postoperative hypertrophy. - Answer-A. The pressure of the 30 cc balloon against the walls of the urethra, where the prostate was removed by electrocautery, allows hemostasis, while the lumen of the catheter can be used to irrigate clots from the bladder. A 60-year-old obese patient with a history of diabetes and renal insufficiency has undergone drainage of an abdominal abscess through a midline incision. Which of the following should the surgical first assistant consider during wound closure? A. Multifilament, absorbable suture material provides for optimal wound healing. B. A continuous suture line should be utilized. C. An interrupted retention suture should be utilized. D. Use of blunt surgical needles is a consideration in the presence of infection. - Answer-C. Interrupted retention suturing effectively provides a secondary suture line relieving strain on the wound and providing a better opportunity for healing by first intention. A 70-year-old patient who underwent an 8-hour colon resection is at the greatest risk for which of the following? A. diverting colostomyB. postoperative infection C. myocardial infarction D. hyperthermia - Answer-B. All 3 components to this question are contributing factors to higher risk of wound infection: 1) the age of the patient, 2) the extended time of the procedure, and 3) the wound classification. A complication of steep reverse Trendelenburg position is A. deep vein thrombosis. B. arterial compression. C. cardiac overload. D. respiratory alkalosis. - Answer-A. Steep reverse Trendelenburg position decreases venous return. Sequential compression stockings are applied to prevent deep venous thrombosis. A patient involved in a motor vehicle crash arrives in the OR. The patient presents with the following: The surgical first assistant should prepare the OR for A. a ORIF left femoral fracture. B. a left temporal craniotomy. C. a repair of the left temporal laceration. D. an exploratory laparotomy. - Answer-D. Clinical hypotension and blood in the urine indicate intraabdominal injury. Exploratory laparotomy is necessary and should be the initial step in the surgical treatment of the patient. A patient scheduled for elective surgery has a positive pregnancy test. Which of the following is MOST appropriate? A. Proceed with surgery regardless of the trimester. B. Only proceed with surgery during the first trimester. C. Use a general anesthetic with a halogenated agent only. D. Defer the surgery until after the delivery. - Answer-D. Elective surgical procedures should be deferred until after delivery of the neonate, once the anatomic and physiologic changes of pregnancy have returned to normal. A pledgeted suture is used for hemostasis in liver injury toA. align the suture placement. B. add bulk to the injury site. C. reduce the likelihood of suture cut- through. D. provide traction for increased exposure. - Answer-C. Pledgeted sutures (buttresses) are sutures passed through a small patch of reinforcing material (usually Teflon). This type of suture is used in areas where the surgeon considers buffering to be beneficial, particularly in delicate or friable tissue. A threaded cortical screw cannot provide compression of bone fragments unless the A. hole is tapped. B. screw is self-tapping. C. near cortex is overdrilled. D. screw is cannulated. - Answer-C. Cortical screws can function in interfragmentary compression if the hole in the near cortex is overdrilled. A. The ascending aorta carries oxygenated blood to the patient via the aortic cannula. C. The right ventricle is not used in the bypass circuit at all. D. The right superior pulmonary vein is used for left ventricular venting through a vent cannula - Answer-INFO A. The splenic artery runs retroperitoneal below the stomach C. The common duct is medial to the stomach. D. The pancreatic duct is retroperitoneal and underneath the stomach. - Answer-INFO According to Maslow's Hierarchy of Needs, which of the following patient needs should be met first? A. esteem B. belonging C. physiological D. safety - Answer-C. Physiological needs must be met first before any of the other needs can be considered. Physiological needs include breathing, circulation, and the patient's physical condition.An epidural catheter is introduced into a patient in the preoperative holding room. When the patient is given a bolus of local anesthetic in the OR, the surgical first assistant observes hypotension and signs of complete respiratory failure. Which of the following is the MOST likely cause? A. migration of the epidural catheter through the dura B. poor cardiac output C. administration of ropivacaine instead of bupivacaine D. use of a Bier block - Answer-A. With patient movement, the epidural catheter may migrate through the dura. A bolus injection into the subdural space can cause total spinal anesthesia resulting in hypotension and respiratory failure. Blood spatterings on the lens of an operative microscope should be removed with A. alcohol. B. water. C. fred. D. saline. - Answer-B. Distilled water is used with a cotton ball or cotton-tipped applicator when removing blood, water, and irrigating solutions from the lens surface. During a carotid endarterectomy, the arteries are unclamped and reclamped before arteriotomy closure is performed to A. flush free debris from the carotid bulb. B. restore complete blood flow to the brain. C. increase collateral flow. D. ensure patency of the carotid body. - Answer-A. Before complete closure, blood flow is temporarily restored through the arteries to wash away debris, such as free plaque, air, or thrombi. During a carotid endarterectomy, the final occlusion clamp to be removed after anastomosis is on the A. common carotid. B. internal carotid. C. external carotid. D. thyroid branch. - Answer-B. The clamp on the internal carotid artery should be removed last so that all debris left in the area is flushed out through the external carotid artery.During a Nissen fundoplication, care should be taken when placing medial traction on the stomach to prevent avulsion of the A. splenic artery. B. gastric arteries. C. common duct. D. pancreatic duct. - Answer-B. The gastric arteries run between the greater curvature of the stomach and the spleen. During a routine abdominal hysterectomy, the anesthesiologist notes that the patient is becoming progressively tachycardic. He notes that there has been virtually no blood loss. The surgeon requests additional muscle relaxation because the patient's abdominal musculature is "tightening up." The esophageal temperature probe indicates a core body temperature of 103°F (39°C). The anesthesiologist notices that the CO2 monitors are alarming with high levels. The anesthesiologist turns off his anesthetic agent, hyperventilates the patient with 100% oxygen, and administers which of the following drugs? A. succinylcholine B. dantrolene C. atropine D. epinephrine - Answer-B.The scenario is describing the anesthesia emergency malignant hyperthermia (MH). Dantrolene is the medication given to combat MH (2-3 mg/kg until signs are controlled). Some signs of MH are tachycardia, tachypnea, hypercarbia, muscle stiffness and rigidity, hypoxia, elevated BP, cardiac dysrhythmias, changes in CO2 absorption, and elevated temperature.
