If rounding is required, round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["0.4"]

Given:

Ordered dose of methylprednisolone succinate: 1.5 mg/kg/day IV in divided doses every 6 hours

Child's weight: 42 kg

Concentration of methylprednisolone succinate: 40 mg/mL

Step 1: Calculate the total daily dose of methylprednisolone succinate:

Total daily dose (mg) = Ordered dose (mg/kg/day) x Child's weight (kg)

Total daily dose (mg) = 1.5 mg/kg/day x 42 kg

Total daily dose (mg) = 63 mg/day

Step 2: Calculate the dose per administration:

Since the medication is given every 6 hours, there are 4 administrations per day.

Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day

Dose per administration (mg) = 63 mg/day / 4 administrations/day

Dose per administration (mg) = 15.75 mg

Step 3: Calculate the volume to be administered per dose:

Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)

Volume (mL) = 15.75 mg / 40 mg/mL

Volume (mL) = 0.39375 mL

Step 4: Round to the nearest tenth:

Volume (mL) ≈ 0.4 mL

Correct Answer is ["1"]

Explanation

Given:

Ordered dose of loratadine: 5 mg

Concentration of loratadine suspension: 5 mg per 5 mL

1 teaspoon = 5 mL

Step 1: Determine the volume of loratadine suspension to be administered:

Since the ordered dose and the concentration are the same (5 mg), the volume to be administered is 5 mL.

Step 2: Convert mL to teaspoons:

1 teaspoon = 5 mL

Volume in teaspoons = 5 mL / 5 mL/teaspoon

Volume in teaspoons = 1 teaspoon

Correct Answer is ["6"]

Explanation

Given:

Ordered dose of Oxytocin: 2 milliunits/min

Concentration of Oxytocin: 20 units in 1 liter (1000 mL) = 20 units/1000 mL = 0.02 units/mL

Step 1: Convert milliunits to units:

Ordered dose (units/min) = Ordered dose (milliunits/min) / 1000 milliunits/unit

Ordered dose (units/min) = 2 milliunits/min / 1000 milliunits/unit

Ordered dose (units/min) = 0.002 units/min

Step 2: Calculate the infusion rate in units/hour:

Infusion rate (units/hour) = Ordered dose (units/min) x 60 minutes/hour

Infusion rate (units/hour) = 0.002 units/min x 60 minutes/hour

Infusion rate (units/hour) = 0.12 units/hour

Step 3: Calculate the infusion rate in mL/hour:

Infusion rate (mL/hour) = Infusion rate (units/hour) / Concentration (units/mL)

Infusion rate (mL/hour) = 0.12 units/hour / 0.02 units/mL

Infusion rate (mL/hour) = 6 mL/hour
