The healthcare provider prescribes amoxicillin 500 mg PO every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hours. The available suspension is labeled, "Amoxicillin Suspension 250 mg/5 mL. Based on this child's weight, how many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the whole number.)
The Correct Answer is ["10"]
First, we need to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So,
Weight in kg= Weight in pounds/2.20462 = 2.2046288 ≈ 39.92kg
The prescribed dosage is 500 mg every 8 hours, which means three doses per day (since there are 24 hours in a day). Therefore, the total daily dosage is 500 mg * 3 = 1500 mg.
The recommended maximum safe dose is 50 mg/kg/24 hours. Therefore, the maximum safe dosage for this child would be:
Maximum safe dosage in mg=Dosage per kg×Weight in kg=50mg/kg×39.92kg=1996mg
Since the prescribed daily dosage (1500 mg) is less than the maximum safe dosage (1996 mg), it is safe to administer the prescribed dosage.
The medication is available in a concentration of 250 mg/5 mL. Therefore, the volume to be administered per dose in mL would be:
Volume in mL= Dosage per dose in mg/ Concentration in mg/mL = 500mg/50mg/mL = 10mL
So, the nurse should administer 10 mL of Amoxicillin Suspension per dose.

Correct Answer is ["1.5"]
Explanation
Here's how to calculate the number of levothyroxine tablets the nurse should administer:
1. We know:
Prescribed dose: 0.075 mg of levothyroxine (given)
Tablet strength: 50 mcg per tablet (given on the medication label)
2. We need to find:
Number of tablets to administer
3. Calculation:
To find the number of tablets, divide the prescribed dose (in milligrams) by the strength of each tablet (in milligrams).
Number of tablets = Prescribed dose (mg) / Tablet strength (mg/tablet)
Number of tablets = 0.075 mg / 50 mcg/tablet
Important note: We need to convert the tablet strength from mcg to mg for consistency in units. Remember, 1 mg is equal to 1000 mcg.
Tablet strength (mg/tablet) = 50 mcg/tablet / 1000 mcg/mg
Tablet strength (mg/tablet) = 0.05 mg/tablet
Now, plug in the converted values:
Number of tablets = 0.075 mg / 0.05 mg/tablet
Number of tablets = 1.5 (round to nearest tenth as requested)
Therefore, the nurse should administer 1.5 tablets.
Correct Answer is ["0.29"]
Explanation
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer for one dose:
1. Convert client weight to kilograms (kg):
Weight (kg) = Weight (pounds) / 2.205
Weight (kg) = 126 pounds / 2.205
Weight (kg) = 57.14 kg (round to two decimal places for better accuracy)
2. Calculate the dose per administration based on weight and prescribed dose:
Dose per administration (units) = Prescribed dose (units/kg) x Weight (kg)
Dose per administration (units) = 50 units/kg x 57.14 kg
Dose per administration (units) = 2857 units (round to nearest whole number)
3. Calculate the volume (mL) to administer for one dose:
Volume (mL) = Dose per administration (units) / Concentration (units/mL)
Concentration (units/mL) = 10,000 units/mL (given on the vial label)
Volume (mL) = 2857 units / 10,000 units/mL
Volume (mL) = 0.2857 mL (round to nearest hundredth as requested)
Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa for one dose.
