A nurse is administering a unit of RBC 300 mL over 2 hr to a client who has anemia. The nurse should set the IV pump to deliver how many mL/hr? Round to the nearest whole number. Enter numeric value only (numbers and decimal points only, no commas or labels)
The Correct Answer is ["150"]
Identify the given information:
Total volume: 300 mL
Time: 2 hours
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
300 mL/2 hr = X mL/1 hr
Cross-multiplying gives us:
300 mL x 1 hr = 2 hr x X mL
Simplifying:
300 = 2X
Solving for X:
X = 300 / 2 = 150 mL/hr

Correct Answer is ["15"]
Explanation
Identify the given information:
Prescribed dose: 6 million units of penicillin G benzathine
Available concentration: 400,000 units/mL
Determine the volume to be administered:
We can set up a proportion to solve for the unknown volume (X):
400,000 units/mL = 6,000,000 units/X mL
Cross-multiplying gives us:
400,000 units x X mL = 6,000,000 units x 1 mL
Simplifying:
400,000X = 6,000,000
Solving for X:
X = 6,000,000 / 400,000 = 15 mL
Correct Answer is ["1.3"]
Explanation
Identify the given information:
Prescribed dose: 12.5 mg of diphenhydramine elixir
Available concentration: 50 mg/5 mL
Determine the volume to be administered:
We can set up a proportion to solve for the unknown volume (X):
50 mg/5 mL = 12.5 mg/X mL
Cross-multiplying gives us:
50 mg x X mL = 12.5 mg x 5 mL
Simplifying:
50X = 62.5
Solving for X:
X = 62.5 / 50 = 1.25 mL
Round off to the nearest tenth:
1.25 rounds off to 1.3 mL
