Consent is important!

Recently on my cardipumonary placement I was treating a patient in NSU (nursing specialty unit) with my supivisor. The patient had been admitted followig exacerbation of COPD, but had mets and lung ca, with the doctors deeming him pallitive. They had requested chest physio to decrease his WOB and anxiety.
I began to explain breathing startegies when the patient became quite distressed explaining he had not slept well and just had a sleeping med so would prefer to comply with physio in the afternoon. I agreed, though my supivisor interrupted and insisted- due to her heavy case load that we would treat him now. The patient declined treatment due to fatigue and resp distress, yet my supivisor persisted. I was hestitant as a student to interrupt, yet I felt she had breached the pts rights.
I looked on the treatment sessio with the pt becoming increasingly distressed, and finally left the room feeling the supiviso had crossed the line.
On reflection I should have interrupted for the pts sake, but as a student felt I was in no position to do so. In the future I will always remember that above all- the patients consent is important as well as a legality.
