A patient on fluid restriction is weighed each morning under the same conditions. The patient's weight increases by 1 kg in 24 hours. Which interpretation is most appropriate?
Correct answer: C. The patient has retained about 1 litre of fluid
- A. The patient has retained about 100 mL of fluid
- B. The patient has retained about 500 mL of fluid
- C. The patient has retained about 1 litre of fluid
- D. The patient has retained about 2 litres of fluid
Explanation
A rapid gain of approximately 1 kg usually represents about 1 litre of retained fluid, because 1 litre of water weighs about 1 kg. Daily weights are useful for detecting fluid changes that may not yet be obvious on physical examination.
