What is the lab test commonly used in the assessment and treatment of acid-base balance?

Arterial blood gas

The nurse is responding to a client's call light. The client states, "I was getting out of bed and caught my IV on the siderail. I think I may have pulled it out." The nurse determines that the intravenous (IV) catheter has been almost completely pulled out of the insertion site. Which action is most appropriate?

daily weights

A client who is NPO prior to surgery reports feeling thirsty. What is the physiologic process that drives the thirst factor?

decreased blood volume and intracellular dehydration

A nurse who has diagnosed a client as having "fluid volume excess" related to compromised regulatory mechanism (kidneys) may have been alerted by what symptom?

distended neck veins

Edema happens when there is which fluid volume imbalance?

extracellular fluid volume excess

During a blood transfusion, a client displays signs of immediate onset facial flushing, hypotension, tachycardia, and chills. Which transfusion reaction should the nurse suspect?

hemolytic transfusion reaction: incompatibility of blood product
