<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>
Answer:
element Y and Z
Explanation:
Having on valence electron indicates that these elements are on the same column/group of the periodic table. Both these elements will bond with a -1 charge.
Echinoderms have radial symmetry.
Answer:
Plasmolysis occurs when a <u>plant </u>cell is inmersed in a <u>3X salt solution</u>.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
- <em>Plamolysis does not occur in </em><u><em>animal cells</em></u><em>.
</em>
- <u><em>Pure water </em></u><em>does not produce plasmolysis.</em>
