Telemetry Medications fully solved graded A+

Telemetry MedicationsCardiac Glycosides are used for Used to increase the efficiency of the heart and improve the contraction of the heart muscle Cardiac Glycosides Negative Inotropic effect Slows the heart rate by decreasing the conduction through the SA and AV node Cardiac Glycosides Positive inotropic effect Increases the force of contraction of the cardiac muscle Cardiac Glycosides treat... CHF or Heart failure, Afib, Aflutter Anti-arryhthmic Agent Class I Sodium-channel blockers which block the fast sodium channels, thereby slowing the electrical conduction in the heart Anti-arryhthmic Agent Class II Beta-blockers work by blocking sympathetic nervous system stimulation to the heart, thereby reducing the transmission of impulses within the hearts conduction system Anti-arryhthmic Agent Class III Potassium-channel blockers bind to and block the potassium channels which prolongs repolarization of the cell membrane. Anti-arryhthmic Agent Class IV Calcium-channel blockers which inhibit the calcium channels reducing the movement of calcium ions in the call during action potentials. Beta-blockers action... -Decrease activity of the sympathetic nervous system on certain tissue -Decrease HR -Decrease cardiac workload and O2 demand -Provide stabilization of dysrhthmias Beta-blockers used for... HTN and certain arryhthmias Beta-blockers monitor and watch for.. -Monitor weights -Encourage pt. to get up slowly and avoid hot showers -Can mask hypoglycemic response Action of Calcium channel blockers -Cardiac and vascular smooth muscles contraction depends on calcium moving across the walls of the cell -Decrease contractility and conductivity -Decrease O2 demands -Dilate coronary and peripheral arteries Action of vasodilators -Widen blood vessels and cause a decrease in vascular resistance and an increase in blood flow -May act by activations of the vasomotor center in the brain, which brings about relaxation of the smooth muscle in the blood vessel walls, OR they can act locally on blood vessel smooth muscle cells Vasodilators are used for.. HTN, angina, and CHF Action of Loop diuretics Prevent reabsorption of sodium and chloride ions in the loop of Henley Action of Thiazide diuretics Inhibit sodium reabsorption at the distal convoluted tubules
