The nurse is assigned to watch the cardiac monitors in the constant care unit and notes four different clients displaying arrhyt
Tresset [83]
<span>The nurse should give the highest priority care to the Ventricular Arrhythmias Patient. Because Ventricular arrhythmias start in the heart's lower chambers, the ventricles. They can be very dangerous and usually require medical care right away. Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an abnormal electrical impulses that start in the ventricles and cause an abnormally fast heartbeat. This often happens if the heart has a scar from a previous heart attack. Usually, the ventricle will contract more than 200 times a minute. Ventricular fibrillation is an irregular heart rhythm consisting of very rapid, uncoordinated fluttering contractions of the ventricles.The ventricles do not pump blood properly, they simply quiver. Ventricular fibrillation is life threatening and usually associated with heart disease. It is often triggered by a heart attack.</span>

Which one of the following statements about the troposphere is
Dvinal [7]

Answer:

B. The tropospheric gases move becuase of convection currents.

Explanation:

The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
