Answer to Question 1

ANS: B
A patient who is hypothermic may not have good circulation to the extremities. The nurse should assess the patient's circulation, and if it is poor to the extremities, choose another spot at which to measure the oxygen saturation. Moving the probe to another finger or removing nail polish will not help if the problem is poor circulation. The nurse should document appropriately, but needs to do more than just charting that the reading could not be obtained.

Answer to Question 2

ANS: D
The pulse pressure is the difference between the systolic and diastolic blood pressure readings. In this case, 142 - 76 = 66.
