Final answer:
The approximate blood volume for a 48 kg adult patient is 3.84 liters or 3,840 milliliters, calculated using the fact that blood constitutes about 8% of adult body weight and that there are 1,000 milliliters in a liter.
Step-by-step explanation:
To estimate the approximate blood volume of an adult patient who weighs 48 kg, we can use the general principle that blood constitutes about 8 percent of adult body weight. For adult females, the average blood volume is typically between 4 and 5 liters. Therefore, to calculate the blood volume for this particular patient, we would use the following calculation:
Blood Volume = Body Weight (kg) × Percentage of Blood Volume
Blood Volume = 48 kg × 0.08 (or 8%) = 3.84 liters
To convert this volume to milliliters, we multiply by 1,000 (since there are 1,000 milliliters in a liter), which gives us:
Blood Volume = 3.84 liters × 1,000 = 3,840 milliliters
Thus, the approximate blood volume for a 48 kg adult female patient would be about 3,840 milliliters.
