Answer 1

Answer

47) E) All of the above

Explanation : Shock is the decrease in Arterial systolic blood pressure below 50 mmHg (Hypotension).

Hypotension causes decrease blood flow to peripheral tissue hence less oxygen delivery.

Decrease blood flow to the lung causes carbon dioxide accumulation in blood resulting in increase generation of H+ ion.

48)D) All Of the above

Explanation :- Diastolic blood pressure indicates peripheral vascular resistance. Low diastolic pressure means peripheral vascular resistance is diminished. If diastolic pressure is not obtained then it means korotkoff sound is still present.

49) D) All Of the above are correct

Explanations :- ADH is the antidiuretic hormone which conserve water from the kidney. This increases the blood volume and so is the venous return.

Loss of ADH results in diuresis with low blood volume. Low blood results in decrease venous return----low stroke volume - - - decrease cardiac output.

50) A) Vasodilation increases
