Night Shift Nurse

He is responsible for narcotic drugs and reporting. At night, the nurses in that service consult with that nurse. If the shift nurse cannot resolve the situation, she is interviewed by the supervisor. They can do the patient distribution again, etc.. 
is there a similar practice in your country or hospital?

The hospitals that I've worked in my career have similar staff responsible on the night shift for different duties, barishan.

A House Supervisor is typically a seasoned nurse with a good amount of time at the facility who is pretty much in charge of the hospital. Each unit or floor then has a charge nurse who may work with other RNs and/or LPNs & CNAs or Techs.

The chain of command is followed should any problem arise: CNA or Tech > LPN > RN >Charge Nurse > House Supervisor. For example, if a patient has a situation where which the direct card staff can't handle, the House Supervisor is informed of the problem.

Narcotic counts are usually done every shift by an off going and oncoming nurse.

The last hospital where I worked, the House Supervisor assigned beds on the medical floors to patients coming from the ER, however, the Charge Nurse on the psych units typically assigned the beds for those patients.
