Mrs Alensi returned to the ward 1 hour ago following a Left sided total knee replacement. She has a morphine infusion running at 1mg/hour for pain relief. 30 minutes ago, her BP was 115/75 and her respirations were 16.

Choose all the statements that are correct. When the heart beats, first the right side of the heart contracts, and then the left side of the heart contracts. That is one heartbeat. The sympathetic nervous system speeds up the heart rate and the parasympathetic system slows down heart rate. M Bradycardia is when the heart beats faster than normal. The SA node is the pacemaker of the heart. Coronary arteries deliver blood to the muscle of the heart. A heart attack is a myocardial infarction. The ECG (EKG) has a QRS wave that represents ventricular depolarization (the message to tell the ventricle to contract. The heart needs nerve stimulation in order to contract.

Identify the following:   Normal Sinus Rhythm   Sinus Bradycardia            Sinus Arrhythmia            Sinus Arrest
