The nurse says they are reading wrong because there is a 2% difference in the blood oxygen levels between them. What is wrong? -         This is normal operation A sterilizer has a jacket pressure of 30 psi and a chamber pressure of 28 psi. What is wrong with it? -         This is normal operation when a cycle is running. The EEG is used to detect: _______ ________ -         Brain Tumors Steam Sterilization Temperatures are usually above: -         132 Degrees Celsius Ultrasound is best described as: -         Acoustic compressions [and rarefactions propagated through matter] During Synchronous Cardioversion -         The defibrillator is set to fire approx 20ms after the peak of the "R" wave What is the Highest Temp that an infant warmer should be before the alarm is tripped. -         39 degrees Celsius The treatment of high bilirubin in babies is treated by; -         Light Therapy Ultrasound Energy for imaging is produced by -         Piezoelectric Crystal What is the most life-threatening problem associated with an IV Pump? -         Air Embolism A paper speed of 25mm/sec is set on an ECG recorder. The patient's heart rate is 60 beats per minute. In a normal ECG waveform, how often will the R wave show up on the paper? -         Every 5 big boxes on the paper Using your test equipment you feed a 1milli volt signal into ECG leads. You have the monitor set to read on lead 2. You are using a 3 lead set. The monitor ECG size is set to 1 milli volt. You run a strip on the recorder. What should you see for amplitude on the recording? -         Two big squares on the paper positive deflection What selection on an electro surgical unit most resembles a sine wave? -         Pure cut The purpose of a grid on an x-ray bucky is to: -         Stop scatter radiation from going to the film or detector The normal test load for a defibrillator is: -         50 ohms non-inductive An ECG monitor acquires the respiration wave and rate from: -         ECG lead 2 A tourniquet stops the flow of blood to a patient's body part that is being operated on by: -         Pumping up to a pressure higher than the patient's blood pressure and restricting flow. A centrifuge spins at 3432 RPM at one scheduled preventive maintenance check. This centrifuge is checked on a quarterly schedule. At the next scheduled preventive maintenance it reads 2600 RPM. What would the most likely case for this problem be? -         Different rotor head was installed. A nurse calls you to repair a non-invasive blood pressure unit. The nurse tells you that the blood pressures are too high when using this unit. What is the most likely cause of this problem? -         Blood pressure cuff is too small. Name the A) standard speed and B) two optional speeds on an ECG machine. -         25 mm/s, 50 and 100 mm/s What is the cause of a wandering base line? -         Movement of electrode on skin A tabletop sterilizer gets up to 220 degrees F and about 5 psi and then times out. What is the most likely cause of this problem? -         The bellows will not close The pure cut waveform of an ESU is. -         Low crest You have a lot of noise on leads I, III and AVL. Which electrode or lead would look at first? -         LA Write in the proper tank colors for each gas listed Oxygen Carbon Dioxide Nitrous Oxide Cyclopropane Helium Nitrogen Air -
