Answer to Question 1
A
Feedback:
A living will is a document in which clients state the types of treatment they desire to receive or not to receive if a terminal situation arises or if they are unable to make decisions or express their wishes. A durable power of attorney for healthcare designates a person of the client's choice to make these healthcare decisions should the client become incompetent. An individual may have a do not resuscitate (DNR), do not intubate (DNI), or both orders in his or her health record. Healthcare personnel are thus informed that if this person experiences cardiopulmonary arrest, a code blue (or the code name for arrest in that facility) should not be called. The use of tube feedings may also be specified as a treatment the client wants or does not want. Clients who are DNR or DNI or who refuse tube feedings will be kept as comfortable as possible and given emotional support.

IV fluids are administered via the circulatory system to correct or to prevent fluid and electrolyte imbalance in the client.
