Question 1 1 / 1 pts When assessing the SaO2 with a pulse oximeter, the nurse will place the oximeter on a finger: while exercising the arm to stimulate circulation. on a finger that has a good circulation and temperature on the same side as the blood pressure cuff. on the same side as the fracture in sling. The pulse oximeter should be placed on a finger of the hand that is normal temperature because hypothermia will affect the reading. The device should not be put on a finger on the same side as a blood pressure cuff or arterial line. Question 2 1 / 1 pts The nurse assessing an 11-year-old who is having an asthma attack heard high-pitched, whistling adventitious sounds of: friction rub. vesicular crackles. wheezes. The narrowed bronchioles characteristic of an asthma attack would produce sibilant wheezes, which are high-pitched whistling sounds. Question 3 1 / 1 pts A nursing student prepares to instruct a client to expectorate a sample of sputum that will be sent to the laboratory for Gram stain, culture, and sensitivity and describes the procedure to the licensed practical nurse (LPN), who is the primary nurse. The LPN corrects the student if which incorrect description is provided? “I will send the specimen immediately to the laboratory.” “I will have the client take a breath and gather his saliva before shallow coughing.” “I will use a sterile container from the supply area.” “I will ask the client to brush the teeth and rinse the mouth before expectorating.” Rationale: Because of the nature of the test, the sputum must be collected in a sterile (not a clean) container. The client should brush the teeth and rinse the mouth to decrease the number of contaminating organisms. The client should take a few deep breaths, and then cough forcefully (not spit) into the container. The specimen should be sent directly to the laboratory. It should not be allowed to stand for long periods at room temperature to prevent overgrowth of contaminating organisms. Test-Taking Strategy: Note the strategic words “incorrect description.” These words indicate a negative event query and ask you to select the incorrect procedure for collecting the sputum sample. Noting the words “shallow breath” in option 4 will direct you to this option. Review the procedure for collecting a sputum sample if you had difficulty with this question. Question 4 1 / 1 pts A patient, age 22, is admitted with acute asthma. It is important to monitor his oxygen saturation levels. The quickest way to assess his saturation of oxygen is to use pulse oximetry. do a pulmonary function test. do a pulse pressure assessment. get arterial blood gases. In acute asthma, oxygen therapy should be started immediately, and its administration should be monitored by pulse oximetry. Pulse oximetry is noninvasive and provides continuous monitoring of SaO2.
