A client is experiencing fluid volume deficit from heat exhaustion. Which laboratory studies should the nurse assess to help determine improvement in the client's condition?
1. Amount of fluid obtained during a lumbar puncture
2. Blood cultures
3. Serum glucose level
4. Urine specific gravity
Answer: 4
1. A lumbar puncture does not determine hydration status.
2. Blood cultures are used to determine the presence of a systemic infection.
3. Serum glucose does not reflect fluid volume status.
4. A urine specific gravity is done, and when normal, reads 1.010-1.035. The higher the number, the greater the dehydration.
