“Nausea is not an allergic reaction to the medication.”
“If she is asleep, we will press the button for her so she won’t wake up in pain.”
Number 4 is correct.
No one other than the client should press the button to deliver medication, in order to avoid oversedation. Remind the family to report if anyone other than the client administers a dose. The family should call if the pump starts beeping or the client becomes oversedated. Nausea is not an allergic reaction.
