In the ICU setting, a patient transported from surgery following open heart bypass grafting will likely have his core temperature measured by a/an
A) rectal tube inserted to prevent evacuation from bowels while recovering from anesthesia.
B) temperature probe taped behind his ear.
C) esophageal flexible thermometer monitoring aorta distention.
D) pulmonary artery catheter being used to measure cardiac output.
Ans:
D
Feedback:
Core temperature may be obtained by a rectal tube, by using an esophageal flexible thermometer, from a pulmonary artery catheter used for thermodilution measurement of cardiac output, or from a urinary catheter with a thermosensor that measures the temperature of urine in the bladder. Since CABG patients have their core temperature decreased to the 80s, the pulmonary artery catheter is the best choice for measuring core temperature while they are still under the influence of anesthesia.
