Which action would be the nurse's best response? * A: Close the door and discuss the UAP's action when the UAP comes out of the room. B: Ask the UAP to come back inside the room and then reenter closing the door. C: Say nothing to the UAP but report the incident to the nursing supervisor. D: Enter the client's room and discuss the matter with the UAP immediately. Rationale: Closing the door fixes issue with preventing air from entering hall and contaminating the hospital environment. when correcting UAP it should be done in private. Ask the UAP to come back inside the room and then reenter closing the door is disrespectful and should be corrected in private. The nurse is responsible for any task delegated and should not pass the buck Correction should never be done in the presence of the client. 2 0.50 78.95% 35.00% 0.44 0.32 B 24 #41 2 2 Question ID / Rev: 19436 / 1 35.20 60.28 2.94 2.94 8.84 -6.76 2.18 2.32 -0.20 0.44 -0.10 -0.05 Upper 27% 0.21 0.79 0.00 0.00 Lower 27% 1.50 0.35 0.10 0.05 Performance History: # Correct: 40 # Incorrect: 28 # Not Attempted: 0 Difficulty: 0.59 Q: The nurse is caring for a client with a tracheostomy tube. Which nursing intervention is most effective in promoting effective airway clearance? A: Suctioning respiratory secretions several times every hour * B: Administering humidified oxygen through a tracheostomy collar C: Instilling normal saline into the tracheostomy to thin secretions before suctioning D: Deflating the tracheostomy cuff before allowing the client to cough up secretions Rationale: Humidification of air will help keep the mucous membranes moist and will make secretions easier to expel. Suctioning should be done only as needed; too frequent suctioning can damage the mucosal lining, resulting in thicker secretions. Normal saline should never be instilled into a tracheostomy because this could lead to infection. The purpose of the tracheostomy cuff is to keep secretions from entering the lungs; the nurse should not deflate the tracheostomy cuff unless instructed to do so by the physician.3 0.40 47.37% 40.00% 0.07 0.09 A 17 24 NIA Question ID / Rev: 17708 / 2 % Selected 41.18 25.00 0.00 35.28 10.00 Point Biserial (rpb) -6.95 6.21 10.00 3.68 Disc.

C: Administer the medication by rapid IV infusion to reduce these effects. D: Nothing: these are expected side effects of this medication.

If these adverse effects or a severe reaction occur, the infusion must be discontinued (while the patient is closely monitored) and the prescriber contacted.
