Math Problem - can anyone solve this? - GoFuckYourself.com

Your 78 kg patient has 400 mg dopamine in 250 ml D5W running at 12 ml/hr. What dose of dopamine is the patient receiving?

A) 2 mcg/kg/min

B) 4 mcg/kg/min

C) 5 mcg/kg/min

D) 6 mcg/kg/min

GrouchyAdmin · 08-28-2009, 07:37 PM

12ml ~= 1200mcg 1200mcg/60min = 20mcg/min
78kg/20mcg/min = 3.9 mcg/kg/min

That's assuming at the 12ml is the dopamine amount not watered down.. I really don't understand the whole statement.

I'm not doing your hw for you -- master dimensional analysis otherwise you are fuced.

AIbenjamink · 08-28-2009, 07:50 PM

I calculated ~4.1 mcg/kg/min, B?

woj · 08-28-2009, 08:04 PM

Just plug shit in and cancel stuff out, this isn't rocket science...

eroticsexxx · 08-28-2009, 10:19 PM

B) 4 mcg/kg/min

Patient is 78 kg. The ordered dose would have to be for 4 mcg/kg/min since:

78 kg x 4mcg/kg/min = 312 mcg/min.

312mcg/min x 60min/hr = 18720mcg/hr which equals mg= 18.72 mg/hr.

18.72 mg/hr x 250mL/400mg = 11.7 (12) mL/hr the running rate.

d-null · 08-28-2009, 10:40 PM

these things always freak me out when the answer is inexplicably rounded off to 1 significant digit

Zorgman · 08-28-2009, 10:42 PM

First, whats my patient's name? Is she sexy?

Mr Pheer · 08-28-2009, 11:07 PM

See, gay math problems that round like that shouldn't be allowed. It should be exact fucking answers or the question should ask "which dose is the closest to what the patient is receiving". Do enough rounding with shit and all of a sudden #s can get way off in a hurry.

Just start low and turn up the volume till you start feeling good and then keep it there.
If your vision get blurry then turn it down slightly.

God damn it's been 10 years since I had to do this on the streets lol
400mg of Dopamine in 250 cc D5W = 1600 mcg/cc
60 min/hr

= 26.6 mcg/cc/min

When I was a paramedic we didn't use bags of 250cc's we always used 500/1000 and it was N/s sometimes Ringers *shrugs*

Answer is B.

KRosh · 08-30-2009, 10:48 AM

400mg / 250 = x mg/1 ml

250 x = 400

x = 1.6

Concentration is 1.6 mg/ml
Convert mg to mcg

1.6 (mg) X 1000 (mcg per 1mg) = 1600 mcg /ml

(ml/hr) 12 X 1600 / (time) 60 min/hr X 78 (weight in kgs) = 19200 / 4680

X = 4.1 mcg/kg/min

potter · 08-30-2009, 01:24 PM

The answer is E.
