Answer :
A 1-kg gain in body weight is equal to a 1000-mL fluid gain. This patient has gained 1.5 kg, or 1.5 liters of fluid.
A 1-kg gain in body weight is generally considered to be equal to a 1000-mL fluid gain. This is because fluids have a density close to 1 g/mL. In the given scenario, the patient's weight increased from 97.3 kg to 99.4 kg, indicating a gain of 2.1 kg. However, the question specifies that the urine output has been less than the intravenous and oral intake, implying that the patient is retaining fluids.
By subtracting the patient's weight yesterday (97.3 kg) from their weight today (99.4 kg), we find that they have gained 2.1 kg. Since the patient is not eliminating fluids efficiently through urine, this weight gain can be attributed to fluid retention. To convert this weight gain to fluid volume, we can apply the conversion rate of 1 kg = 1000 mL. Therefore, the patient has gained approximately 1.5 liters (1500 mL) of fluid.
This information is valuable for the nurse because it suggests that the patient's body is accumulating excess fluid. Monitoring fluid balance is crucial in healthcare, as abnormal fluid retention can be a sign of underlying medical conditions or indicate a need for adjustments in medication or treatment.
