Question

Lactulose 20 gm is to be administered to a patient through gastric tube. On hand is lactulose syrup 10 gm/15 mL. How much will the nurse give:
1. 1 mL
2. 10 mL
3. 20 mL
4. 30 mL

Answer 1

Correct Answer - Option 4 : 30 mL

CONCEPT: 

Basic dosage calculation

\(Dose ={D\,{(Desired\,dose)} \over{H\, (Amount\, on\,hand)}}\times V\, (volume)\,\)

 

CALCULATION:

• According to the question mentioned above;

D (desired dose) = 20gm

H (amount in hand/ available dose) = 10gm

V (volume)= 15 ml

 

\(Dose ={20*15\over10 }\,\)

Dose = 15

Hence, the correct answer is 30ml.
