A nurse is reviewing a prescription for ibuprofen 150 mg PO with the parent of a child. Available is ibuprofen suspension 100 mg/5 mL. How many tsp should the nurse advise the parent to administer to the child? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Step-by-step calculation:
The desired dose of ibuprofen is 150 mg.
The available medication concentration is 100 mg/5 mL.
We need to convert mL to tsp.
Calculating the volume to administer in mL:
Use the concentration of the medication: 150 mg ÷ (100 mg/5 mL) = 150 mg ÷ 20 mg/mL = 7.5 mL
Converting mL to tsp:
1 tsp = 5 mL
7.5 mL ÷ 5 mL/tsp = 1.5 tsp

Correct Answer is ["0.24"]
Explanation
Step 1: Convert the infant's weight from pounds to kilograms.
To convert pounds to kilograms, we use the conversion factor 1 kg = 2.2 lb.
Weight in kg= 21/2.2≈9.55 kg
Step 2: Calculate the total daily dose of clindamycin in mg.
Total dose in mg/day=15 mg/kg/day×9.55 kg=143.25 mg/day
Step 3: Divide the total daily dose into 4 equal doses (every 6 hours).
We divide the total daily dose by 4:
Dose per administration=143.25 mg/4=35.8125 mg/dose
Step 4: Determine the volume to administer per dose.
The available clindamycin phosphate injection concentration is 150 mg/mL. To determine how many mL the nurse should administer per dose, we use the following formula:
Volume (mL)=Dose in mg/Concentration in mg/mL=35.8125 mg/150 mg/mL=0.238 mL
Step 5: Round the answer.
Rounding off 0.238 mL gives 0.24 mL.
Correct Answer is ["850"]
Explanation
Step by step calculation:
The desired dose of magnesium hydroxide is 0.85 g.
We need to convert grams to milligrams.
Converting grams to milligrams:
1 g = 1000 mg
0.85 g x 1000 mg/g = 850 mg
