A nurse is preparing to administer magnesium hydroxide/aluminum hydroxide 30 mL PO to an adolescent. How many oz should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1"]
Step 1: Identify the conversion factor.
We need to convert milliliters (mL) to ounces (oz). The conversion factor is:
1 ounce (oz) = 30 milliliters (mL)
Step 2: Set up the conversion.
The prescribed dose is 30 mL. We want to convert 30 mL to ounces.
Using the conversion factor:
Amount in oz=Amount in mL/Conversion factor=30 mL/30 mL/oz
Step 3: Perform the calculation.
Amount in oz=30/30=1 oz
Step 4: Round the answer (if needed).
1 oz is a whole number

Correct Answer is ["0.67"]
Explanation
Identify the formula for volume to administer:
Volume (mL)=Dose ordered (mg)/Available concentration (mg/mL)
Substitute the given values:
Dose ordered = 25 mg
Available concentration = 37.5 mg/mL
Volume=25/37.5=0.6667mL.
Round to the nearest hundredth:
0.6667=0.67mL.
Correct Answer is ["2.7"]
Explanation
Step 1: Convert the child's weight from pounds to kilograms.
We know that 1 kg = 2.2 lb,
Weight in kg=Weight in lb=78/2.2≈35.45 kg
Step 2: Calculate the required dose of ondansetron in mg.
The prescribed dose is 0.15 mg per kg:
Dose in mg=0.15 mg/kg×35.45 kg=5.318 mg
Step 3: Determine the volume of ondansetron to administer.
To determine how many mL the nurse should administer, we use the following formula:
Volume (mL)=Dose in mg/Concentration in mg/mL=5.318 mg/2 mg/mL=2.659 mL
Step 4: Round the answer:
Rounding 2.659 mL gives 2.7 mL.
