Just because unsafe care is common does not mean we have to risk our patients and our license.
At minimum tell a supervisor or your manager about your concerns. Keep a diary at home and write about every shift, eliminating any potential HIPAA violations. When it is so unsafe yot have to tell a manager or supervisor write who you told, what you said, and how he or she answered.
If there is harm to a patient or you make a mistake the fact that you reported unsafe conditions can mitigate your punishment if reported to the board of nursing or help in court if you are one of the rare nurses sued for malpractice. (I think malpractice insurance
is worth the <$100.00 a year)
If you are bold and work with other nurses willing to do so speak up at a staff meeting. Take notes.
You can put your concerns in writing. Write it twice or make a copy and give it to a management person with the authority to obtaine more staff.
If all the above don't help you can write your concerns in detail and sent them to the hospital attorney.
If there is whistleblower protection for nurses in your state you can report unsafe conditions to the state agency that licenses hospitals. Or report to CMS.
Most hospitals make a profit. There is currently no shortage of nurses. There is no excuse for them not to provide sufficient staff to care for patients and meet their needs.
