A 2 mL solution containing 1.20 μCi/mL is injected into the blood stream of a patient. After dilution, a 1.00mL sample is withdrawn and found to have an activity of 2.4×10−4 μCi . Calculate the total blood volume in Liters
Homework Answers
Rsample = Rtracer * (Wsample / (Wsystem + Wtracer))
soo
2.4*10 ^-4 = 1.20 * (1/(Wsystem + 2))
Solve for Wsystem
2.4*10 ^-4 = 1.20 / (Wsystem + 2)
Wsystem = 1.20 / (2.4*10 ^-4) - 2
Wsystem = 4998 mL

Morphine is injected intravenously into a patient’s blood stream in a solution of 2 mg/mL at a rate of 1 mL/hour. The patient is bleeding at a constant rate of 3 mL/hour. The patient normally has 5 L blood in their body, and will lose consciousness if they lose more than 40% of their total blood volume. What is the concentration of morphine in their blood (mg/L) by the time they lose consciousness, assuming they have excellent circulation?
