Answer to Question 1

A
The amino groups in amino acids contain nitrogen. Amino acids do not contain potassium, iron, or sodium.

Answer to Question 2

1, 2, 3, 4
Rationale: Symptoms of dehydration can include sudden weight loss, increased heart rate, confusion, tachycardia, and hypotension. The elderly are at an increased risk for dehydration due to blunted thirst perceptions. The recommended fluid intake for females is 2.7 L/day. Edema results from a fluid overload rather than dehydration.
