Think "cardiac" with both. Hyperkalemia is the most deadly of all electrolyte imbalances.

Describe the Cardiac Cycle The Cardiac cycle is a description of the activities that take place in the period from the start of one heart the next. The conducting system autonomically controls the heart beat impulses it is also called the cardiac conduction system or the nodal system. It is made up of six main components the sinoatrial node (SA-Node)‚ internodal paths‚ atrioventricular node (AV-Node)‚ atrioventricular bundle (AV bundle) or bundle of His‚ bundle branches and Purkinje fibres.

and their cusps flatten against the arterial walls as the blood rushes past them. When the ventricles relax‚ the blood flows backward toward the heart‚ it fills the cusps & CLOSES the valves. THE AV VALVES. ~ 2 AV valves are located at each atrial-ventricular junction‚ prevent backflow into the atria when the ventricles are contracting. : 1) Tricuspid Valve-the right AV valve has 3 flexible cusps. 2) The Mitral Valve-the left AV valve with 2 flaps. It is sometimes called the bicuspid valve

or stress. The parasympathetic nervous system slows down the heart rate during periods of rest. The Sino-atrial node sends electrical impulses around the heart muscle and tells it how fast it should be beating according to the impulses received from the parasympathetic and sympathetic nervous systems. Every few seconds‚ the Sino-atrial node sends out nerve impulses which branch across the atrial muscle fibres and cause a contraction. These impulses are received by the atrio-ventricular node which stimulates

“the nursing process is often conceptualized as the integration of singular actions of assessment‚ diagnosis‚ and identification of outcomes‚ planning‚ implementation‚ and evaluation.” For instance‚ I remember taking care of a patient who had atrial fibrillation and I could see in the telemetry monitor that the heart rate would fluctuate within 110-150’s‚ the patient was asymptomatic. I called the doctor and reported my patient’s status; I received new orders to administer digoxin intravenously. After

Research Paper on Acute Respiratory Distress SyndromeAbstract Acute Respiratory Distress Syndrome is a life-threatening condition that results from injury to the alveolar-capillary membrane. The condition is associated with extensive pulmonary inflammation and small blood vessel injury in all affected organs. ARDS is considered to be more the end result of a variety of severe injuries instead of an actual disease. ARDS was first officially discovered in 1967. There are 3 identified stages of ARDS
