Nursing....... any regrets ?

Hello i'm a nursing student who finished his first year and after sitting through 6 weeks of clinical attachments i'm beginning to hate nursing. i entered nursing of course with an ideal to save lives , but the 6 weeks spent at a general medical ward and a surgical orthopedic ward has shown me otherwise.

From my observation , nurses they do roll calls ******** about doctors , serve medications , escort patients to the toilets , serve bedpans/ urinals , clean patients up . That's what nurses can do .

However things like oxygen therapy , pain management , cases of vomiting and severe medical issues . the trend in this pattern is that we would require a doctor to assess and plan out his/her required treatment and management of the patient so we nurses have to implement . I remember asking my RN what we have to do when a patient is vomiting and she answered "just get her a vomit bowl the doctor will come " and i stood there baffled expecting more than what she could answer.

Why do we then learn about physical assessments , pharmacology , anatomy & physiology when nobody in clinicals care about what u know. The hours spent reading up on orthopedic textbooks , pathology just to prepare for clinical is wasted because we are supposed to be kept in our place and allow the doctors to do their thing because of the disparity of decision making between nurses and doctors. and that made me so affected that nurses couldn't do anything more than they could do

Right now i'm facing a dilemma between doing biomedical engineering, life sciences or just continue with nursing to eventually hope that all of the issues i'm facing would turn for the better....
