Answer:
32 mL
Explanation:
Step 1: Covert pounds to kilograms. This problem's units are already in kg, so no conversion is necessary.
Step 2: Calculate the number of hours an infusion will last by dividing the volume in the bag (1 liter,or 1000 mL) by the rate per hour: 1000 mL/100 mL/h = 10 hours.
Step 3: In case the problem asks for a dose per minute, you will need to multiply the hours by 60 to convert to minutes, but this problem does not ask for it, it asks for ug/kg/hr, so no need to convert here.
Step 4: Now plug into the equation: 4 ug/40 kg/10 hr = 1600 ug.
Step 5: Now convert the ug into mg by dividing by 1000: 1600/1000 = 1.6 mg.
Step 6: Then calculate the quantity of fentanyl to add, by dividing the 1.6 mg by the concentration of the drug (0.05 mg/mL): 1.6 mg/0.05 mg/mL = 32 mL.
Note: to be truly accurate when adding drugs to bags like this, you should discard 32 mL of fluids from the bag prior to adding the 32 mL of fentanyl.
The answer is B. diaphragm

Loss of breath or a concussion
Answer:
0.4 ml
Explanation:
The mother solution contains 10 mCi, but the patient just need 4 mCi.
So using a rule of three, it would be:
10 mCi - 1 ml
4 mCi - X X = (4x1) /10 = 0.4 ml
And considering the half life of 6 hours, need to pass 18 h to have a dose in the body that is insignificant. (at the first 6 h it will have 2 mCi, at the next 6 hours 1mCi, at the next 6 hours 0.5 mCi)
So it would be 0.4 ml of the mother solution every 18 h.
