Case study #1

Mr. T, age 75, has been vomiting intermittently for the past 24 hours. His weight today is 165lbs compared to a baseline of 165lbs. Upon assessment, the nurse notes that his mucous membranes and skin are dry. His vital signs are: temp 99.4, pulse 120, respiration 32, and blood pressure 90/60. His urine output for the last eight hours is 150ml. On review of the morning lab work the electrolyte findings are: K 3.5, Na 145, and the Hematocrit and BUN are elevated.

Question 1: Identify a problem the nurse would be concerned about. Based on the findings above, what is a priority nursing diagnosis?

Question 2: List appropriate nursing interventions and how the nurse would evaluate the effectiveness of each intervention related to the priority nursing diagnosis that you have identified.
