Question

You receive the following order for a patient that presents to the ED with acute alcohol intoxication: Folic acid 1mg, thiamine 100mg, Multivitamin 10ml in 0.9% Sodium Chloride 1000ml. The nurse sets the infusion rate to 125ml/hr. How many milligrams of thiamine will the patient receive per hour?

a. 12.5mg
b. 8mg
c. 10mg
d. 1.25mg

Answer 1

The patient will receive 12.5 milligrams of thiamine per hour, as determined by the infusion rate and initial thiamine concentration in the IV bag.

Step-by-step explanation:

The student's question pertains to calculating the amount of thiamine administered per hour when infused at a rate of 125ml/hr with an initial thiamine concentration of 100mg in 1000ml 0.9% Sodium Chloride. To solve this, we need to calculate the proportion of thiamine administered per the 125ml of infused solution per hour from the total 1000ml bag.

Here's the calculation:

• Total thiamine in bag: 100mg
• Total volume of bag: 1000ml
• Infusion rate: 125ml/hr
• Thiamine per hour = (Thiamine in bag / Volume of bag) * Infusion rate
• Thiamine per hour = (100mg / 1000ml) * 125ml/hr
• Thiamine per hour = (0.1mg/ml) * 125ml/hr
• Thiamine per hour = 12.5mg

Therefore, the patient will receive 12.5 milligrams of thiamine per hour at the infusion rate of 125ml/hr.
