Non-contrast Computed Tomography (NCCT) Final Exam Test Bank Questions & Answers, With Explained Rationales (from Actual Test)

Non-contrast Computed Tomography (NCCT) Final Exam Test Bank Questions & Answers, With Explained Rationales (from Actual Test)-Which of the following solutions is contraindicated on the sterile field for an endoscopic case using electrosurgical instruments? A. chlorahexidine B. betadine C. sterile water D. normal saline - D. Normal Saline Rationale: Cholorahexidine and betadine are not expected on the field, but are not contraindicated. Sterile water would normally be used in this case since electrocautery is used. Sterile water is nonconductive. Normal saline is contraindicated because it can conduct electricity and could inadvertently burn other tissue when using electrosurgical equipment. The patient is scheduled to have a Meniscal repair done on his right knee. Which of the following best represents how the site should be marked in the preoperative holding area to verify correct surgical site? A. A "yes" written on the right knee, with a small line showing where the incision will be. B. An "X" marked on the right knee, with a small line showing where the incision will be. C. An "X" marked on the left knee, showing that this is not the correct surgical site. D. A "no" written on the left knee, showing that this is not the correct surgical site. - A. "yes" written on the right knee, with a small line showing where the incision will be. Rationale: The operative site will be marked by the surgeon. Indelible marker should be used, so that prep solutions, drapes and tape do not inhibit the ability to read it clearly. The word "yes" or the surgeon's initials are commonly acceptable ways to mark the correct surgical site. "X" or "no" are not acceptable, as to it could lead to confusion or misunderstanding of whether site is correct or not. During surgery, the surgical technologist reaches for a supply item being handed by the circulator. The surgical technologist's left glove touches the outside of the package. Which of the following steps must be taken to correct the break in sterile technique? A. The surgical technologist must break, re-scrub, and re-gown and glove. B. The surgical technologist must remove the contaminated glove and re-glove herself. C. The circulator removes the contaminated glove and then the technologist re- gloves herself. D. The circulator removes the contaminated glove and re-gloves the surgical technologist away from field. - C. The circulator removes the contaminated glove and then the technologist re-gloves herself. Rationale: Because the surgery is already in progress, it is not necessary for the surgical technologist to re-scrub and re-gown. The circulator can remove the contaminated glove, and the surgical technologist can re-glove. The surgical technologist cannot remove their own glove, because the surgery is in progress. And the surgical technologist cannot leave the sterile field since the surgery is in progress. During a vaginal hysterectomy the surgical team noticed that the safety belt was left off the patient before the drape was applied and discovered after draping. How can the patient be secured to the OR bed without interrupting the sterile field or procedure? A. The surgical technologist can watch for movement of the patient and inform the circulator. B. The anesthesiologist can secure the head to prevent shifting. C. The circulator can reach under the sterile drape and apply the safety strap. D. The surgeon can request sterile coban to secure the patient. - C. The circulator can reach under the sterile drape and apply the safety strap. Rationale: The underside of the drape is not sterile, therefore, can be touched by the unsterile circulating nurse, while she secures the patient with the safety strap. Which of the following information is the surgical technologist responsible for reporting to the circulating R.N. to document in the OR record? A. amount of diprivan (Propofol) used B. amount of actavis (Fentanyl) used C. amount of prep solution used D. amount of x-ray contrast used - D. amount of x-ray contrast used Rationale: The circulator always documents all medication used during the procedure, including contrast. Propofol and Fentanyl are both used by anesthesia for general surgery. The amount of prep solution does not need to be documented.. During a vascular procedure a vessel is ligated. The surgeon states that she will repair the vessel after bleeding is controlled. Which needle type would she most likely require to complete this task? A. French eyed needle B. control release needle C. cutting needle D. tapered needle - D. tapered needle Rationale: A tapered needle is often used for vascular, GI, and most soft tissue. A cutting needle penetrates through tougher tissue, such as skin. A control release needle is better for placing interrupted sutures or when there's a need for rapid release of the needle. Use of a French eye needle results in greater tissue damage than an eyeless needle, like the tapered needle. During a colon resection, an endo GIA misfired. Where should the surgical technologist bring the endo GIA after surgery? A. Materials Management B. CS assembly department C. decontamination area D. Biomed - C. decontamination area Rationale: The endo GIA was opened during the colon resection so it is considered unsterile and contaminated. It would need to go to the decontamination area. Material management is where supplies for the hospital are kept. Central processing department is where instruments are put together and re-processed for use. During the initial pre-operative count, the surgical technologist and circulator noticed that there were 11 Raytecs in a package instead of 10. Which of the following should they do about the extra sponge? A. Include the extra sponge in the count. B. Throw out one sponge to make it 10. C. Discard the entire package into a kick bucket and remove it from count. D. Remove the package and the sponges from room. - D. Remove the package and the sponges from room. Rationale: If the patient has not entered the room the Raytecs are to be removed from the sterile field. They are then taken out of the room. Sponges used during the case are counted in the kick bucket so the incorrect sponges should not be placed in it. Raytec sponges come in a total of 10, so subtracting one from the count would complicate the surgery if relief would come in. Which of the following is the minimum amount of time an unwrapped Kelly clamp needs to be flash sterilized for? A. 6 minutes B. 3 minutes C. 7 minutes D. 12 minutes - B. 3 minutes Rationale: The minimum amount of time is 3 minutes. Which of the following resources should the surgical technologist use if a question arises concerning the correct use of a cleaning solution? A. OSHA regulations B. CDC guidelines C. MSDS D. Bowie-Dick test sheet - C. MSDS Rationale: OSHA is the Occupational Safety and Health Administration. CDC stands for the Centers for Disease Control and Prevention. Material Safety Data Sheets (MSDS) contains information on all hazardous chemicals: precautions for handling the chemicals, the hazards associated with chemicals, and the firefighting techniques--along with first aid for exposure. The Bowie-Dick test is used to test and monitor high vacuum steam sterilizer. Ten minutes into an automatic chemical washer cycle for an instrument string, the surgical technologist notices she has missed a few critical instruments. Which of the following should the technologist do? A. Immediately power down the washer and add the instruments. B. Wait until the washer stops and run a new cycle with the instruments. C. Open the washer door on the dirty side and add manually decontaminated instruments. D. Open the washer door on the clean side and add manually decontaminated instruments. - B. Wait until the washer stops and run a new cycle with the instruments. Rationale: The correct thing to do is wait until the cycle stops then add the instruments and start a new cycle. The instruments should not be added to the stringer until they have gone through the washer sterilizer. It is not good to abort the cycle.
