GOOD NCLEX-RN Pharmacology Math web..

[Shaw-way RN]

hi everyone!

i would like to share one good nclex-rn pharmacology math web.

http://www.accd.edu/sac/nursing/math/titration2.html

there have many information for pharmacology.

some math question similar in nclex-rn exam.

ex:the physician orders dopamine (intropin) 400 mg in 250 mg d5w tra 5 mcg/kg/min. for the client who weighs 110 lbs, how many ml /hr will the pump be set?

ex:dopamine (intropin) is infusing at 15 cc/hr. the bag has 200 mg / 250 cc d5w. the

client weighs 145 lbs. how many mcg/kg/min is the client receiving?

there also have many practicequiz.

the practicequiz's list:

● matching: equivalencies

● matching: abbreviations

● multiple choice: basic calculations

● multiple choice: iv calculations

● multiple choice: titration (critical care)

● multiple choice: pediatric focus

● multiple choice: pulling it all together

hope can help!:redpinkhe

:redbeathe dear stefano,

here you go!

[color=#6600ff]a) the physician orders dopamine (intropin) 400 mg in 250 mg d5w tra 5 mcg/kg/min. for the client who weighs 110 lbs, how many ml /hr will the pump be set?

[color=#6600ff]answer:

[color=#6600ff]1) [color=#6600ff]first: to find concentration.

[color=#6600ff]400 / 250 = 1.6 mg/ cc = 1600 mcg/cc

[color=#6600ff]2) convert lbs to kg.

[color=#6600ff]110 / 2.2 = 50

[color=#6600ff]3) 5 (dose) x 50 (kg) x 60 / 1600 (concentration) 5 x 50 x 60

[color=#6600ff]= 15,000

[color=#6600ff][color=#6600ff]4) 15, 000 / 1600 = 9.375

[color=#6600ff]answer is 9.375

[color=#6600ff][color=#6600ff]b) dopamine (intropin) is infusing at 15 cc/hr. the bag [color=#6600ff][color=#6600ff]has 200 mg / 250 cc [color=#6600ff][color=#6600ff]d5w.

[color=#6600ff][color=#6600ff]the client weighs 145 lbs. [color=#6600ff][color=#6600ff]how many mcg/kg/min is the client [color=#6600ff][color=#6600ff]receiving?

[color=#6600ff][color=#6600ff]answer:

[color=#6600ff][color=#6600ff][color=#6600ff]1) [color=#6600ff]first: to find concentration.

[color=#6600ff][color=#6600ff]200 / 250 = 0.8 mg/cc = 800 mcg/cc.

[color=#6600ff][color=#6600ff]2) convert lbs to kg.

[color=#6600ff][color=#6600ff]145 / 2.2 = 65.90

[color=#6600ff][color=#6600ff]3) 15 (rate) x 800 (concentration) / 60 x 65.9.

[color=#6600ff][color=#6600ff]15 x 800 = [color=#6600ff][color=#6600ff]12,000

[color=#6600ff][color=#6600ff]60 x 65.9 = 3954

[color=#6600ff][color=#6600ff]12,000 / 3954 = 3.03

[color=#6600ff][color=#6600ff]answer is 3.03

hope they could help...:redpinkhe
