Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20

Doctor's order: Infuse 50mg of Amphotericin B in 250ml NS over 4 hr 15 min; Drop factor : 12gtt/ml. What flow rate ( ml/hr) will

svlad2 [7]

Answer:

59 ml/hr

Step-by-step explanation:

Amount of solution = 250 ml

Flow rate = 250 ÷ 4.25 hrs = 58.82352941176 ml/hr

since answer is required in ml/hr and not gtt/hr,

Therefore answer = 59 ml/hr to the nearest flow rate.
