Correct Answer is ["1.5"]
Explanation
Step 1: Determine the ratio of milligrams per tablet from the available tablets.
The available tablets are labelled "100 mg/tablet." This means that for every 1 tablet, there are 100 milligrams of desipramine.
Step 2: Calculate the number of tablets needed for 150 milligrams.
We can set up a proportion to solve for the unknown number of tablets:
(100 mg) / (1 tablet) = (150 mg) / (x tablets)
Cross-multiplying:
100 mg x x tablets = 1 tablet x 150 mg
Step 3: Solve for x (the number of tablets).
Divide both sides of the equation by 100 mg:
x tablets = (1 tablet x 150 mg) / (100 mg)
x tablets = 1.5 tablets
Correct Answer is ["100"]
Explanation
Here's how to calculate the IV pump rate:
1. Calculate the total infusion time in hours:
30 minutes / 60 minutes/hour = 0.5 hours
2. Calculate the infusion rate:
Total volume (mL) / Infusion time (hours) = Infusion rate (mL/hr)
50 mL / 0.5 hours = 100 mL/hr
