Question

Which of the following are true regarding an increase in SVR? Diastolic pressure will increase Systolic pressure will increase Left ventricular work will increase Myocardial oxygen consumption will increase Which of the following are true regarding hyperventilation and exercise? Hyperventilation helps to compensate for lactic acidosis Hyperventilation begins as soon as lactate production increases Hyperventilation facilitates diffusion of oxygen Hyperventilation is facilitated by increased pulmonary capillary blood flow Hyperventilation occurs when tidal volume and rate begin to increase Which of the following will result in metabolic alkalosis? Increase in HCO_3^- T Loss of HCO_3^- increase in PaCO_2 Decrease in PaCO_2

Explanation / Answer

12. In metabolic alkalosis, the bicarbonate concentration of the plasma is increased without undue changes in the carbonic acid concentration. Metabolic alkalosis occurs in the following conditions.

1. Ingestion of large doses of alkalies in the treatment of peptic ulcers.

2. Excessive vomiting with loss of huge amount of gastric juice as in cases of intestinal obstruction.

3. Removal of large amounts of gastric secretion as a gastric suction. There is also the loss of chloride. So more carbon dioxide is retained.

Hence, the correct answer is the option (A).
