Answer:
Option B, not know that respirations are being assessed
Step-by-step explanation:
If you have ever seen any of the Toy's Story movie, think about how when the toys are being watched, their behaviors change immediately. It would be hard for Andy to accurately know what is going on in the lives of the toys, right? We can apply this same principle to assessing patient respirations.
When the patient knows that the nurse is counting their respirations, they can easily alter the results by hypoventilating, hyperventilating, or otherwise presenting an abnormal breathing pattern which could, in turn, change the nurse's documentation of vital signs and, subsequently, their plan of care.
Because of this, the nurse should know that when assessing the patient's respirations, it is important for the patient to not know that respirations are being assessed.
There are a few ways nurses can disguise that they are assessing a patient's respirations: 1) tell the patient you are taking their pulse and while you do so, watch their chest rise and fall; 2) listen to the patient's heart and lungs sounds and watch chest rise and fall; 3) while holding regular conversation with the patient, look at chest rise and fall -- this may not be accurate though because in order to speak, one must hold their breath.
Whichever method the nurse uses or develops, the main goal for the patient to not know respirations are being assessed as to not interfere with the assessment, option B.
