A solution is to be administered by intravenous infusion at a rate of 45 mL/h. (1) drops/min should be infused if the administration set deliver 40 drops/mL. Round answer to the nearest whole number. Do not include units.
Answer and Explanation

The Correct Answer is ["30"]

Step 1 is to identify the volume per hour and the drop factor

Volume: 45 mL

Time: 60 minutes

Drop Factor: 40 drops/mL

 

Step 2 is to calculate the drops per minute (gtt/min)

(Total Volume × Drop Factor) ÷ Time in minutes

(45 × 40) ÷ 60

45 × 40 = 1800

1800 ÷ 60 = 30

Result at this step = 30

 

Step 3 is to round to the nearest whole number

30 = 30

Correct Answer is D

Explanation

Step 1. Set up the alligation grid.

Higher strength: 12.5%

Lower strength: 3%

Desired strength: 7%

Step 2. Calculate the parts.

Parts of 12.5% solution = 7 - 3 = 4 parts

Parts of 3% solution = 12.5 - 7 = 5.5 parts

Total parts = 4 + 5.5 = 9.5 parts

Step 3. Calculate volumes for 855 mL.

Volume of 12.5% = (4 / 9.5) x 855 = 360 mL

Volume of 3% = (5.5 / 9.5) x 855 = 495 mL

Correct Answer is D

Explanation

Step 1 is to convert the aspirin dose per suppository to grams

300 ÷ 1000 = 0.3

Result at this step = 0.3 g

Step 2 is to calculate the weight of the base displaced by the drug

(Drug weight ÷ Density factor)

(0.3 ÷ 1.3) = 0.2307

Result at this step = 0.2307 g

Step 3 is to calculate the actual weight of the base needed per suppository

(Weight of blank base - Weight of base displaced)

2 - 0.2307 = 1.7693

Result at this step = 1.7693 g

Step 4 is to calculate the total number of suppositories

(Total base available ÷ Base needed per suppository)

31 ÷ 1.7693 = 17.52

Result at this step = 17.52

Step 5 is to round down to the nearest whole number for completed suppositories

17.52 ≈ 17
