Calling for help!

Say a client worsens in condition or the nurse is unable to answer an important question; How does a nurse call for help?
Call the doctor or 911.

It all depends on the location of the nurse/patient. If both are already in the hospital, you can call on your charge nurse, or call the specialty department for an answer to a specific question (i.e. pharmacy, respiratory, social work etc), or phone the doctor, or call a code to get a bunch of people to help.

Personally, I stick my head out of the patient's door and yell to the nurses' station, "I need some help in here NOW". Or, if it's a code situation, I push the blue button on the wall and holler "Someone call a code 33".

Do you mean like a code situation or just a change in patient condition? If I'm worried about the patient's status (like a major change in BP, heart rate/rhythm etc) then I call rapid response and stay with the patient. If it's a code situation, I'd like to push the call light and tell everyone to come help now, but in reality I'd just yell for help really loud. Where I work now, we wear these gps trackers on our name badge that actually has a button on it that you can push for help. But I'd probably still just yell, lol.

Who are you, and why are you asking this question? I am curious.

Not sure exactly what you're asking. If I can't answer an important question from whom? What kind of question? If you were more specific you might get better answers.

If a pt. is worsening you 1st call for help and then being assessing he/she and report your findings to the rapid response team. If your unable to anwser a question you let the pt know that you are unsure, but you will try to find out the anwser.
