Question 11
Anarel [89]

Answer:

the trainee calculated the incorrect amount

It should be 0.5 mL

Step-by-step explanation:

The physician orders penicillin 500,000 units for a patient while the concentration of the drug you have is 1,000,000 units/ 1mL. It's clear that 1mL drug is too much for the patient since 1,000,000 units are higher than 500,000 units.  

The amount of penicillin in 1.5 mL will be definitely higher than 1,000,000 units, so it must be a lot higher than the physician's orders. We can roughly guess that the trainee draws an incorrect amount.

To calculate the exact volume you need, you have to divide the amount of the drug you need with the concentration of the drug. The calculation will be:

the volume needed = amount of the drug you need/ concentration of the drug

volume needed =  500,000 units / (1,000,000 units/ 1mL)= 1/2 mL = 0.5 mL

How many mor barrel of gasoline than diesel were produced last year
algol [13]

Answer:

3 million barrels

Step-by-step explanation:

Total crude oil=60 million barrels

gasoline 34% diesel 29% total crude oil -60 million barrel · =0.34 times 60

Diesel=20,400,000 and gasoline=17,400,000

Quantity of gasoline = 34% of total crude oil

=0.34 times 60 =20.4

Quantity of diesel = 29% of total crude oil

=0.29 times 60 { million barrels}

Clearly, Quantity of gasoline is more than Quantity of diesel

difference = Quantity of gasoline-Quantity of diesel

20.4 -17.4 milion barrels

Therefore,

The production of gasoline is 3 million barrels more than diesel last year.
