Question

  A nurse must be careful not to inject a drug too quickly into a patient’s IV.  If the drug is injected at the maximum rate of 0.04 cc per second, and the total amount to be injected is 15 cc,

Create an equation that tells the amount injected as a function of time (in seconds);
Determine the time required to complete the injection.

Answer 1

Let t = time passed

 

Let rate = 0.04

 

Let d = amount of drug injected

 

The equation would be:

 

d = 0.04t

 

15 = 0.04t

 

t = 15/0.04 = 375 seconds
