 ** ANSWERS **

75 mL = 44 mL

33 mL = 22 mL

11.5 mL = 11 mL

11,000,000 units / 1,000 mL = 11,000 units/mL

11,000/250,000 = 0.044 x 1,000 = 44 mL

11,000/500,000 = 0.022 x 1,000 = 22 mL 

11,000/1,000,000 = 0.011 x 1,000 = 11 mL

 ** ANSWERS: 47 ML/HR, 108 ML/HR **

2.2 = 80 kg

20000/150 = 133.3333 

1.3 x 80 x 60 = 6240

6240/133.3333 = 46.80 = 47 

 3 x 80 x 60 = 14400

14400/133.3333 = 108

#NacoleMedMath | Nursing Math - Dosage Calculations

 ** ANSWER: 89 ML **

134 ML / 3 = 44.6667

44.6667 x 2 = 89.3333 = 89 ML

#NacoleMedMath | Nursing Math - Dosage Calculations

 ** ANSWER: 17 GTT/MIN **

1,000 ML / 12 HR = 83.3333 ML/HR

83.3333 / 60 MINUTES = 1.3889 ML/MIN

1.3889 x 12 = 16.6667 = 17 GTT/MIN

#NacoleMedMath | Nursing Math - Dosage Calculations

** ANSWER: 1.5 ML **

400 MG / 5 ML = 80 MG/1 ML

120 MG / 80 MG = 1.5 MG

1.5 MG x 1 ML = 1.5 ML

** ANSWER: 4.95 ML ** 

65.91 KG x 0.15 MG = 9.89 MG/KG

9.89 MG/KG / 2 MG/ML = 4.95 ML

#NacoleMedMath | Nursing Math - Dosage Calculations

** ANSWER: 4.70 ML **

62.7 KG x 1.5 MG = 94.05 MG/KG 
94.05 MG/KG / 20 MG/ML = 4.70 ML 

#NacoleMedMath | Nursing Math - Dosage Calculations

** ANSWER: 12.48 ML ** 

83.2 KG x 0.3 MG = 24.96 MG/KG 

 24.96 MG/KG / 2 MG/ML = 12.48 ML

#NacoleMedMath | Nursing Math - Dosage Calculations

** ANSWER: 8.96 ML **

89.5 KG x 0.15 MG = 13.43 MG/KG 

13.43 MG/KG / 5 MG/ML = 2.69 ML

89.5 KG x 0.35 MG = 31.33 MG/KG

31.33 MG/KG / 5 MG/ML = 6.27 ML
