An intrinsic factor that contributes to the development of a pressure injury is: A. Pressure B. Hypothermia C. Diabetes mellitus D. General anesthesia - ✔✔C. Diabetes mellitus An intrinsic factor is related to the health of the patient. Diabetes mellitus is an intrinsic factor that contributes to the development of a pressure injury. Which of the following helps determine a patient's discharge destination? A. Written discharge instructions from anesthesiology and medical staff B. Risk of postoperative complications C. Standardized pain scoring D. General condition and readiness for discharge - ✔✔B. Risk of postoperative complications The choice of discharge site is based on patient acuity, access to follow-up care, and the potential for postoperative complications. Central nervous system (CNS) signs and symptoms of local anesthetic systemic toxicity (LAST) include: A. Hypertension B. Numbness of lips and tongue C. Respiratory depression D. Elevated temperature - ✔✔B. Numbness of lips and tongue CNS symptoms of LAST include circumoral and tongue numbness. All other options are not considered part of the CNS. Autologous bone grafts should be stored at a temperature of: A. 68*F (20*C) B. 32*F (0*C) C. -4*F (-20*C) D. -112*F (-80*C) - ✔✔C. -4*F (-20*C) Maintaining storage temperatures within recommended parameters of -4*F (-20*C) helps ensure that autografts are maintained in optimal conditions for successful replantation. When providing patient education for a child, it is important to understand which learning characteristics of children? A. Children are self-directed B. Children use intrinsic thought processes C. Children respond to use of activities that follow transitions of maturity. D. Children respond to a trial-and-error approach - ✔✔D. Children respond to a trial-and-error approach When teaching children, using a trial-and-error approach is effective. Child learners are task-oriented, use extrinsic thought processes, and value self-esteem. Which of the following actions would decrease radiation exposure during fluoroscopy procedures? A. Positioning the patient as close to the tube as possible B. Positioning the patient as far from the image intensifier as possible C. Positioning the patient as far from the monitor as possible D. Positioning the patient as close to the image intensifier as possible - ✔✔D. Positioning the patient as close to the image intensifier as possible The x-ray beams originate from the tube and are captured by the image intensifier. Multiple studies have demonstrated that positioning the patient closer to the image intensifier results in a significantly decreased dose of radiation. A perioperative nurse is assisting an anesthesia professional with a rapid-sequence induction by providing cricoid pressure using the Sellick maneuver. Which of the following is the most appropriate description of this technique? A. Exerting down-and-up pressure on the cricoid cartilage to compress the trachea B. Palpating for the thyroid cartilage and exerting pressure on it with a dominant index finger and thumb to occlude the esophagus C. Applying pressure on the cricoid cartilage to occlude the esophagus D. Maintaining pressure on the thyroid cartilage until anesthesia verifies placement - ✔✔C. Applying pressure on the cricoid cartilage to occlude the esophagus The Sellick maneuver, more commonly known as cricoid pressure application, involves exerting downward pressure on the cricoid cartilage with the thumb and index finger of one hand to compress the esophagus. The Sellick maneuver is used to prevent potential aspiration during induction of anesthesia. A diagnostic procedure that replies on radio-frequency waves to reproduce cross-sectional images of the body without exposing the patient to ionizing radiation is: A. Ultrasonography B. Position emission tomography C. Computed tomography D. Magnetic resonance imaging - ✔✔D. Magnetic resonance imaging Magnetic resonance imaging stimulates disequilibrium in the nuclei of hydrogen atoms and the water of body cells. As nuclei return to their original state, they emit radiofrequency signals. Which of the following movements of a powered instrument is used to drill holes or to insert screws, wires, and pins? A. Reciprocating B. Oscillating C. Alternating D. Rotating - ✔✔D. Rotating Rotary movement is used to drill holes or to insert screws, wires, or pins. Reciprocating and oscillating movements are used to cut or remove bone. Alternating movement should not be sued. What is the most likely cause of a rapid decrease in blood pressure and heart rate for a patient being infused when 1.5% glycine is used for irrigation? A. Anaphylactic reaction B. Myocardial infarction C. TUR syndrome D. Pulmonary embolus - ✔✔C. TUR syndrome The patient is most likely experiencing TUR syndrome associated excessive glycine absorption. Preoperative teaching is most effective when patients have a readiness to learn and the perioperative nurse teaches from ________ different levels. A. Two B. Three C. Four D. Five - ✔✔B. Three There are three different levels of preoperative teaching: information, psychosocial support, and skill training. Information should include explanations of procedure and what to expect throughout the phases of perioperative care.

Have relaxing music playing in the operating room to avoid overstimulation C. Administer a liter of normal saline prior to surgery to ensure that the patient is well hydrated D. Allow a family member or friend to sit with the patient in the preoperative area and in the post anesthesia care unit. - ✔✔A. Raise the temperature in the operating room to between 26.7*C and 29.4*C (80*F and 85*F). The sickle cell patient must be kept warm to prevent hypothermia and meet increased demands for oxygen. A _______ type of fire extinguisher should be used in an operating or procedure room. A. Wet chemical B. Carbon dioxide C. Halogen D. Dry powder - ✔✔B.
