The heart is a pumping organ that pumps blood to different parts of the body by generating electrical impulses on its own. These electrical impulses generated in the heart are of major clinical significance and thus a system called electrocardiogram (ECG) is used to monitor the electrical activity of the heart. The ECG consists of waves, complexes, segments, and intervals that correspond to different activities of the heart such as the P wave, QRS complex, T wave, U wave, and QT interval. The ECG uses a characteristic graph paper having a square that denotes a particular time interval and this paper runs at the same speed as the ECG system.

Question

While inflating the balloon of a pulmonary artery catheter (PAC) with 1.0 mL of air to obtain a pulmonary artery occlusion pressure (PAOP), the nurse encounters resistance. What is the best nursing action ? a) add an additional 0.5 mL of air to the balloon and repeat the procedure. b) Advance the catheter with the balloon deflated and repeat the procedure. c) Deflate the balloon and obtain a chest x-ray study to determine line placement. d) Lock the balloon in the inflated position and flush the distal port of the PAC with normal saline asap
