Answer:Take as an example

Step-by-step explanation:

7,203 x 6,892. If I want to know that exactly, then I reach for Mathematica (or if I absolutely have to, I reach for pencil and paper to apply multiplication in columns). But often I just need a rough answer, so I mentally convert this to 7,000 x 7,000 = 7 x 7 x 1,000 x 1,000 = 49,000,000. More formally I am converting the numbers the nearest approximation of the form k x 10n where k ∈ {the set of numbers for which I know times tables}. Then I use the times tables on the remaining significant digits and implicitly use the 10 times table to get the magnitude right. In this case the real answer is:

The hcp has ordered cefazolin 500 mg ivpb every 6 hours. the pharmacy sends cefazolin 500 mg in 50 ml of d5/w and it is to run o
madreJ [45]

It is to be noted that the flow rate is 50mL/h for the first instance, and;

100mL/h for the second instance.

<h3>What is flow rate?</h3>

Flow rate (Fr) is computed with the following formula:
Fr (mL/h) = Volume (mL)/ Time (Hours)

<h3>Given that the drop factor of the IVBP set is 60 gtt per ml. what is the hourly rate?</h3>

Time = 1 hour

Volume = 50 mL

It is to be noted that we don't need 500mg because it is already infused into the 50mL solution) hence,

Hourly flow rate = unknown

<u></u>

<u>To compute for Flow Rate (Fr)

</u>Recall that:

Fr (mL/h) = Volume (mL)/ Time (Hours)

Inserting the values we have
Fr = 50/1

Fr = 50mL/h

<h3>What would the hourly rate be if the hcp ordered the cefazolin to run over 30 minutes?</h3>

<u></u>

We have been given the following:
Time = 0.5 hours (30 minutes = 0.5 hours)

Volume = 50mL

It is to be noted that we don't need 500mg because it is already infused into the 50mL solution) hence

Fr = 50/0.5

Fr = 100 mL/h

Simplify the expression. (3 i) - (2 - 2i)<br> a. 1 3i<br> b. 5 - i<br> c. 4i<br> d. -1 - 3i
ololo11 [35]
Just treat 'i' as a placeholder (I know that it represents √-1, but just add 'i' as if it were a placeholder becaseu that is what it is.)

(3+i)-(2-2i)

distribute
3+i-2+2i
group
3-2+i+2i=
1+3i

answer is A
