Correct Answer is ["A","D"]
Explanation
A. Hypotension: When blood pressure drops, the body's ability to transport fluids and electrolytes is compromised, leading to fluid imbalances and ultimately dehydration.
B. Blood clotting: Blood clotting does not directly cause dehydration or increase water needs.
C. Hypertension: Hypertension does not typically cause dehydration; it is more often associated with fluid overload.
D. Gastrointestinal (GI) fluid loss: GI fluid loss, such as from vomiting or diarrhea, leads to dehydration and increases the body's need for water.
E. Low body temperature: While it might seem counterintuitive, low body temperature (hypothermia) can actually increase fluid loss through increased metabolic rate and shivering.
F. Weight gain: Weight gain is more often associated with fluid retention rather than dehydration.
Correct Answer is B
Explanation
A. Aortic valve regurgitation: This condition involves the backward flow of blood from the aorta into the left ventricle, not the left atrium.
B. Mitral valve regurgitation occurs when the mitral valve does not close properly, allowing blood to flow back from the left ventricle into the left atrium during systole.
C. Mitral valve stenosis involves the narrowing of the mitral valve, restricting blood flow from the left atrium to the left ventricle, but does not involve backflow into the left atrium.
D. Aortic valve stenosis is the narrowing of the aortic valve, which restricts blood flow from the left ventricle into the aorta, not back into the atrium.
