Answer to Question 1

Ans: D
Feedback:
When adults older than 65 years of age were compared with younger adults, the plasma osmolarity at which the older group experienced thirst was increased, indicating an increased risk for development of a water deficit.

Answer to Question 2

Ans: A
Feedback:
Metabolic alkalosis occurs when there is excessive loss of body acids or with unusual intake of alkaline substances. It can also occur in conjunction with an ECF deficit or potassium deficit (known as contraction alkalosis). Vomiting or vigorous nasogastric suction frequently causes metabolic alkalosis. Endocrine disorders and ingestion of large amounts of antacids are other causes. The loss of stomach acid or taking in of base causes H+ shifts in the blood, and pH increases.
