To determine the quality of oxygenation, the nurse performs the physical assessment, the arterial blood gas test, and pulse oximetry. What is the purpose of the pulse oximetry technique? a) Monitor the amount of oxygen saturation in the blood b) Monitor the pressure of oxygen dissolved in plasma c) Calculate the pressure of carbon dioxide dissolved in plasma d) Calculate the percentage of hemoglobin saturated with oxygen Monitor the amount of oxygen saturation in the blood Explanation: The pulse oximetry test is a noninvasive transcutaneous technique for periodically or continuously monitoring the oxygen saturation of blood. The arterial blood gases test the client's blood for the partial pressure of oxygen dissolved in plasma, percentage of hemoglobin saturated with oxygen, and the partial pressure of carbon dioxide dissolved in plasma. 1361  Which of the following is a recommended guideline for determining suction catheter depth when suctioning an endotracheal tube? a) Using a spare endotracheal tube of the same size as being used for the patient, insert the suction catheter halfway to the end of the tube and note the length of catheter used to reach this point. b) Combine the length of the endotracheal tube and any adapter being used, and add an additional 2 cm. c) For a closed system, combine the length of the endotracheal or tracheostomy tube and any adapter being used, and add an additional 3 cm. d) Using a suction catheter with centimeter increments on it, insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align and insert the suction catheter no further than an additional 1 cm. Using a suction catheter with centimeter increments on it, insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align and insert the suction catheter no further than an additional 1 cm.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
