Extract:
Four hours after her arrival to the emergency department, the patient remains in second-degree type II heart block and her vital signs are stable. She is transferred to a telemetry unit to prepare for insertion of a permanent pacemaker later in the day. When she gets out of bed to use the restroom, she felt faint and had to sit on the floor. The nurse finds her sitting on the floor beside the commode; the patient is awake but somewhat confused. The nurse notes that the ECG monitor shows that the patient's heart rate is at 40 beats/minute and she is now in third degree heart block. The Rapid Response team is called, and preparations are made for the immediate application of a transcutaneous pacemaker (TCP).
Question 5 of 5
