Answer to Question 1

A
Advance directives are guidelines to be used only if a client cannot make medical decisions for him- or herself. Informed consent implies that the client understands the risks and benefits of the treatment to be performed.

Answer to Question 2

C
Metabolic alkalosis is caused by excessive ingestion of antacids or milk, or by excessive oral or parenteral administration of sodium bicarbonate or other alkaline salts and prolonged nasogastric suctioning. Overly vigorous mechanical ventilation and pain result in respiratory alkalosis. Hyperkalemia results in metabolic acidosis.
