When left ventricular failure occurs, which of the following signs and symptoms relate to the backward effects of heart failure? Select all that apply: a) Hypertension b) Jugular vein distension c)Pulmonary edema d) Paroxysmal nocturnal dyspnea e) Peripheral edema

Correct Answer is (C)

Explanation:

   (c) Pulmonary edema is right answer.  

pneumonic edema is a part of Cardiogenic pulmonary edema which is caused by expanded weights in the heart. When the sick or exhausted left ventricle isn't able to pump out enough of the blood it gets from your lungs.Pulmonary edema is frequently brought about by congestive cardiovascular failure. At the point not able to pump efficiently, blood can back up into the veins that take blood through the lungs. The weight in these veins expands, liquid is driven into the air spaces (alveoli) in the lungs.

The open ocean begins at the low-tide mark and extends to the end of the continental shelf

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
