The output of a solid state electrosurgery unit can measured accurately with -         an RF ammeter in series with a non-inductive resistor 3. The accuracy and reproducibility of cardiac output measurements may be reduced when -         the patient has deep respirations 4. A bedside monitor displays an arterial blood pressure waveform that is damped and the readings are inaccurate. Of the following choices, the likely cause might be that -         air bubbles are present in the pressure line 5. The type of fluid used to test an ultrasound unit's transducer is -         de-gassed water 6. A patient is being monitored by a pulse oximeter. The nursing staff is having trouble obtaining a signal. A possible cause is -         a bad connection at the sensor, in adequate blood flow to the sensor site, and the patient is receiving vasoconstrictive drugs 7. While being used in the operating room, an end tidal CO2 monitor has a low flow alarm. A reasonable first step would be to ask the equipment operator to -         replace the sample tubing 8. A nurse discovers infiltration of an IV site and reports that the IV pump failed to alarm. The technician finds the pump to be operating properly. An additional step, if any is appropriate, that the technician should take is -         explain to the nurse that site infiltrations do not necessarily create enough back pressure to trigger an alarm 9. A dialysis machine has a low dialysate temperature (34 degrees C) and a reference thermistor resistance of 3 kilohms. The thermistor's specifications are 5 kilohms at 23 degrees C, and a temperature coefficient of -1% per degree C. It would be most appropriate to -         replace the thermistor 10. On a local area network, which of the following can cause a loss of communications between the server and the clients: -         a hub losing power 11. A nurse reports that a patient whose blood pressure is being monitored invasively has a BP reading of 150 mmHg. When she takes the patient's pressure with a cuff, she only reads 138 mmHg. This is: -         not unusual 12. You get a call from an anesthesiologist who has a patient on the table in the O.R. He says "We think our patent expired, but if we turn the gain up real high on the EEG recorder, we see some low level signal. How do we determine whether this is cerebral activity or artifact?" Your best response would be -         suggest a neurologist be called to make the determination 13. After using an adult ventilator, a respiratory care provider reports a monitored volume loss without airway pressure changes. Your best first step would be: -         verify that the expiratory flow sensor is functional 14. ** When a 2 millivolt signal is applied differentially to an amplifier input, the output is 4 volts. When a 10 volt, 60 hertz signal is applied as a common signal on both inputs, the output is 1.0 volts. The common-mode rejection ratio (CMRR) of this amplifier is -         20,000:1 15. The load impedance that would normally be use when checking the output waveform of an external cardiac pacemaker is -         500 ohms 16. A thermal dilution cardiac output computer system is indicating an error condition and the temperature recording curve shows a notch. The problem was probably caused by -         a non-continuous injection 37. A nurse has difficulty obtaining a signal on a pulse oximeter with an ear probe. The patient is suffering from exposure and hypothermia. Of the following, the most appropriate recommendation to the nurse is to -         switch to a nasal sensor if available; otherwise warm the patient's ear 38. A nurse is using an IV controller to infuse fluids, and the back pressure alarm sounds. The nurse should be instructed to -         check the infusion site and the line for occlusion or kinked tubing 39. A nurse reports that an automated vital signs monitor is displaying lower than expected blood pressure values. A likely cause is -         using a cuff that is too large 40. A nurse reports a noisy arterial pressure waveform and requests that the technician adjust the monitor. Pressures on the monitor are 170/80 and cuff pressure is 150/80. Of the following, the most likely cause is -         the waveform is underdamped; the catheter tubing is probably too long 41. The detection of IV infiltration is accomplished by -         frequent visual inspections of the infusion site 42. On one patient, the five consecutive thermodilution curves displayed on the cardiac output computer show a "bump" on the upslope. The injectate has been administered smoothly and within 3 seconds. The most likely cause is the patient probably has a -         righ-left cardiac shunt (分流) 43. The x-ray technician complains that radiographic film image is "striped". A likely cause is: -         a stationary Bucky grid 44. A cardiologist asks you to redirect the printout on the central ECG database so that it comes out at the nurses' station instead of the cardiologist's office. This makes sense to you because the nurses can then put the paper directly into the patient's chart. You should: -         ensure the nurses' station printer is in a secure area and consult a HIPPA expert 45. The hospital buys a computerized ECG data acquisition system, composed of a main server and mobile signal acquisition ECG carts. The salesperson said the ECGs could be done at any bedside, and with the cardiograph plugged into the hospital backbone, ECGs are directly archived onto the main server. This works fine from all ports in the hospital except for those on a particular floor. Very likely: -         The Ethernet crossover cable is still attached 46. A biomedical amplifier is "overloaded" when the -         differential input signal times the amplifier gain is greater than the power supply voltage, input DC offset voltage is greater than differential dynamic range, and applied common mode signal is greater than input common mode dynamic range 47. An oxygen monitor has a very long response time to room air. The most likely cause is -         defective galvanic cell 48. During an MIS (Minimally Invasive Surgery) procedure, the nurse specialist reports that the image is dropping in and out on one of the video monitors. A likely cause is: -         bad connection/faulty video cable from source to monitor 49. An EEG acquisition system consisting of 5 nodes and a reader station is connected to the hospital's network backbone (TCP/IP). The EEG tech says the reader station lost the ability to monitor live recordings from node 2. All cables are connected properly. A good troubleshooting first step is: -         ping node 2 from any computer on the hospital network 50. After using an adult ventilator, a respiratory care provider reports a monitored volume loss without airway pressure changes. Your best first step would be: -         verify that the expiratory flow sensor is functional 51. U7A is configured as -         an inverting amplifier 52. One of the hospital's wireless cardiographs will not transmit data to its server. A likely cause is -         The device's wireless Ethernet card has been removed 53. A biphasic defibrillator is set to deliver 200 J. You measure delivered energy into a 50 ohm load and a 100 ohm load. Compared to the first reading, the second reading should be -         the same 54. A healthcare institution uses portable, battery-operated bed exit alarms to prevent patient falls. Intermittent complaints are brought to Biomed's attention: the Nursing staff states that the devices "do not always work." (The model in question utilizes the pressure-sensitive mat technology.) None of them have sent to Biomed for evaluation. How should you approach this problem? -         Ask the nurses to call Biomed to the clinical setting to help troubleshoot the situation when the problems are encountered 55. You are called to the Operating Room first thing in the morning to perform electrical safety test on a loaner device brought in by a salesperson. A surgeon has scheduled an operation using this device (to begin in fifteen minutes), and the salesperson will assist the surgeon in its use. You should -         Be aware of your hospital's policy for rental/loaner/leased devices 56. You are called to an operating room because the table is malfunctioning with a patient on it. All functions on the hand control work except the Trendelenburg position. A good first attempt at resolving the problem quickly would be to -         Replace the hand control 57. You receive two broken ultrasound transducers from your hospital's Ultrasound Department. Neither works after being sterilized by the hospital's Central Sterile Processing Department. In an attempt to help determine what happened, you would initially want to know -         If the transducers worked before they were sent to be sterilized 58. You are asked by your hospital's Central Processing Department to place a service call to the manufacturer of the plasma sterilizer. It seems that after having been sterilized, a flexible endoscope was found to have biologic debris in one of its channels. -         Channels need to be cleaned manually before sterilization 59. The display on an infusion pump reads "KVO". This means -         The pump has delivered the programmed volume and is now continuing to infuse but at a very low rate (KVO = "keep vein open") 60. In upgrading your hospital's monitoring systems so their data can be routed to the EMR, your first question might be -         Do all your monitors have the HL7 options 61. A patient on oxygen therapy desaturates, and the air/O2 blender is called into question. On testing in the Biomedical Lab, the blender is found to be out of calibration (producing 40% O2 when set for 80). On overhauling the device, water is found inside, as well as corrosion of internal components. What is the most likely reason to find water inside an air/O2 blender? -         Moisture in the house medical air line 62. You receive a complaint that one of the dye injectors from the cardiac cath lab is not functioning properly - the device cannot be armed. When you go to look at it, you find dried contrast solution all over the housing. A good first step toward troubleshooting the problem would be -         After powering down the device, open the case and look for contrast liquid leakage on the circuit boards 63. An invasive blood pressure measurement shows negative pressures -         Location of the transducer relative to the patient's heart 64. You receive a complaint from the Coronary Care Unit that the blood pressure alarm keeps sounding on the physiological monitor. Upon investigation, you find the patient to be on a continuous-flow pump Left Ventricle Assist Device (LVAD). The arterial waveform is a flat line, and the display says, "Check A-Line, Non-pulsatile." What is the problem? -         The physiologic monitor is expecting a normal arterial pressure waveform 1. There is a connector labeled "100Base-FX MMF" on the media converter, which routes data into your physiological monitoring server. What sort of data cable is this? -         Fiber optic 2. The main difference between Cat 5 and Cat 6 cable is -
