A nurse is preparing to administer ibuprofen 10 mg/kg PO every 6 to 8 hr PRN pain to a child who weighs 55 lb. Available is ibuprofen suspension 100 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["12.5"]
Step-by-Step Solution:
Convert the child's weight from pounds to kilograms.
1 pound is= 0.453592 kilograms.
55 pounds = 55 x 0.453592 = 24.94756 kilograms.
Calculate the total dose of ibuprofen.
The prescribed dose is 10 mg/kg.
The child weighs 24.94756 kg.
The total dose = 10 mg/kg x 24.94756 kg = 249.4756 mg.
Calculate the volume of ibuprofen suspension to administer.
The available ibuprofen suspension is 100 mg/5 mL.
To find the volume, we can set up a proportion:
100 mg / 5 mL = 249.4756 mg / x mL
Cross-multiplying:
100x = 249.4756 x 5
Solving for x:
x = (249.4756 x 5) / 100 = 12.47378 mL
Round the answer to the nearest tenth.
12.5 mL.

Dose of iron dextran: 75 mg
Concentration of iron dextran: 50 mg/mL
Calculate the volume of iron dextran to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 75 mg / 50 mg/mL
Volume = 1.5 mL
Correct Answer is ["0.019"]
Explanation
Identify the given information:
Dose of haloperidol: 19,000 mcg
Use the conversion factor:
1 g = 1,000,000 mcg
Set up the conversion:
19,000 mcg x (1 g / 1,000,000 mcg)
Calculate the result:
19,000 mcg x (1 g / 1,000,000 mcg) = 0.019 g
